"So, what's the over/under on this going south?" Crow asked

"Figuring that out's all part of the fun." Fie replied.

"Now let's see what's inside." Lea said as Mickey use the Castle of Mirror's Key to open the gate and then they go inside.

The moment, they head inside, they see the Castle of Mirrors interior dramatically changed. The layout of the Castle of Mirror change to an actual castle... however... the backdrop was covered in sinister red and black. Blue Crystals are now red. The globe pedestal blue energy now to black energy.

(Trails into Reverie ost - Maliciousness in the Mirror)

"The layout appears very different from when we last came here." Laura remarked

"I think I know the reason for that. This castle was where a major crisis began in Crossbell as few years ago. Afterward, there was no way people would've come here if it was left as it is, so it was remodeled and shrunk down." Juna explained

"So this is its true form, then." Rean look around and see the globe in the center between the staircases. "But something is definitely amiss here."

"It certainly is. Be careful, everyone. The space inside this castle is being eroded by a world that is not our own!"

"Wait, a world eroded by a world not of our own?" Teddie asked. "Wait, you mean like the TV World?"

"Isn't that the place where you guys went up going in your world?" Qrow asked

"Yes. That's also how we got our Personas from an... incident." Yukiko replied. "But the atmosphere is different compare to the TV world."

"I've recalled you guys also encountered something similar during the Great Twilight. I believe it was in Heimdallr and the Geofront that was taken staged." Naoto Shirogane said.

"How could this be..." Zhongli grit his teeth as he rubs his chin.

"This feeling..." Aqua muttered.

"Is something wrong?" Leo asked.

"Yo, Crow..." Shez looking at him. "Doesn't this feel like..."

"Yeah..." Crow nodded his head, giving a serious look. "The atmosphere feels just like the Realm of Darkness."

"The Realm of Darkness?" Rean looks surprised. "You mean that's where you, Edelgard, and the others went to rescue, Aqua, right?"

"The very same." Arval nodded his head. "The atmosphere of the realm of darkness has this... feeling of dread. Hopelessness fills this void. And the air itself feels sheered cold..."

"Yes..." Tiki shuddered as she wrapped her arms around herself. "I can feel the darkness surrounding this place. It's intimidating."

"Yes... It feels the same kind of dread with Grima..." Lucina muttered. "But... this feels a lot stronger... So this is what the realm of darkness feels like."

"Not to mention the atmosphere of the interior is so... sinister looking." Lissa muttered. "It's like a real version of Halloween."

"I don't like this one bit..." Amia shuddered. "My body is telling me that I should turn back for some reason..."

"I'll admit, it does look scary enough for Halloween." Iggy said.

"I'm guessing the mirrors of this castle are supposed to be a scary reflection?" Leafa asked.

"Mirrors are objects that connect two 'worlds' to one another." Celine said. "You know that Enforcer, Natsume, right? His powers of mirrors are something like this. The mirrors here have literally connection the castle to somewhere that isn't reality."

"That's right. Whoever did this must be someone dangerously powerful." Emblem Vita nodded in agreement.

"Right..." Aqua nodded. "His powers remind me of my time in the realm of darkness where I have to go through a realm within the magic mirror. It was... one of my frightening experiences." Aqua looking around. "And feeling that same feeling in this castle... bring back those haunted memories."

"Aqua..." Laura sadden.

"Whoever our enemy is doing this deliberately."

"But it also means we're in the right place." Morgan fold her arms. "Now let's see what we can find in this dreaded place."

"But don't forget to stay alert. We don't know what's looking." Venti advised.

"Right. Stay close, everyone." Levi agreed as they take off, spotted a couple of Moon Guardians, Dog Mummies, Darkballs, and Neoshadows.

"Heartless and monsters." Ryoma got out his Raijinto.

"Come on, let's deal with them." Mona said as they readied for battle.

The Moon Guardians unleash dark wavelengths toward the group while Neoshadows sink to the ground to launch a sneak attack. They dodge as Fie lung and slash a couple of Dog Mommies as her four of them ran to large with their jaws on, Zhongli, Leon, Tiki and Iggy, but Leo cast his magic to summon tree roots to bind them and then Zhognli killed them with one slash.

The Neoshadows emerges from behind Rean, Laura, Shez and Leafa but they block and counterattack as Aqua swoop in and deal with the final blow while Naoto Shirogane shooting at the Moon Guardians. Levi lung and slash each one and then impale the ground for a circular kick and then unleash a wide spin slash to push them away as Lissa swing her axe fierce to kill them with one blow.

Then more Neoshadows appeared as Morgan throw Excalibur and then two more Moon Guardians join and were pull into the tornados as Yukiko summon Sakuya to imbued the tornado with fire and Arval cloak his hands with dark magic and then clap them as energy appeared and exploded within the tornado, destroying the enemies within.

"Blech." Celine muttered. "It's bad enough the enemies here are gonna be a handful, but the Heartless is even worse."

"It's not unlike when Lohengrin Castle became infested with spirits." Laura said.

"Definitely. The spirit veins must be even more out of whack here than they were there." Rean nodded.

"Indeed. And whoever did this managed to hid it from me until now..." Zhongli muttered

"How could this happen to the star attraction of the whole part?" Juna grimaced. "We've gotta save it!"

"And we will. Let's go and be careful of any enemies lurking in this place." Mickey said as they take off and spotted a couple of Neoshadows with Weiss Clown and Orberoachs patrolling the area.

Crow throw his Double Sabers to hit them repeatedly then Shez teleport around them, dealing phantom slashes and then Laura lung, swing heavily and then slam them down, destroying them. They continue walking and spotted a couple of Sun Guardians, Grimblades, Invisibles, Star Guardians, Speculo II and Speculo I are present. Ryoma, Emblem Roy and Rean lung and slash the Sun Guardians, Grimblades, Invisibles, Star Guardians, Speculo II while Iggy throw magic at Speculo II. The Sun and Star Guardians throw wavelengths attack as the Invisisbles flew toward the group to slash Lissa and Lucina.

Lucina and Lissa block and they swing against them while the Grimblades flew toward Tiki, only to be bakes in fire by her. Teddie claw attack the Moon Guardian as Scizor throw Bullet Punch, Goodra use Dragon Pulse and Polteageist used Giga Drain on the Star Guaridan.

Qrow lung and drag the Invisisble away and slam them and then Aqua swing at them to destroy them. They keep going to the hallway.

"Ehehe..."

Everyone heard a child laughing. "W-What was that?" Juna asked.

"Ahahaha..."

"A child's laughter?" Marth asked

"Oh Aidios... please don't tell we've truly enter a haunted house that has children laughing to add creepy atmosphere..." Mona groaned

"This really is gonna be a Halloween thing, isn't it?" Leafa sighed as they cross the hallways of mirrors, suddenly, the reflection of Juna turn and pull out her Gunbreakers as Rean, Levi, Zongli and Amia sense it.

"Look out!" Amia yelled as Rean lung and slash the bullets.

"Eeek!"

(BGM ended)

"Already underata—" Lissa turn to the Mirrors and see some of the reflectings approaching the mirrors. "aaAAAACK?!" She jawdropped.

"Get ready for battle, everyone!" Rean yelled as the mirror versions of Juna, Celine, Venti, Leo, Tiki, Quaquaval, Butterfree, Teddie, Yukiko, Qrow, Lea, and Amia came out of the mirror.

(Kingdom Hearts: Birth By Sleep ost - Night of Tragedy)

"Holy shit." Qrow got his Harbringer

"Mirror versions of us!?" Venti exclaimed.

"What manner of illusion is this...?!" Marth grit his teeth as the mirrors eyes change to red and cloak in a dark aura.

"I don't know what trick this is, but I've dislike it." Felix readied his sword. "Let's get rid of them!"

"This feel exactly like..." Aqua shuddered as she lowered her head, allowing the Mirror Leo to attack her with magic. "Augh!"

The Mirror Amia lung toward Amia and swing at her, but she block and parried her as she and Emblem Rean thrust and slash her away while Mirror Juna, Mirror Lea, Mirror Qrow and Mirror Quaquaval lung toward the group as Celine throw a fireball along with her Mirror self as Levi, Rean, Zhongli, Laura, Fie, Felix, Qrow, Crow and Shez block Mirrors attacks. Mirror Teddie and Mirror Yukiko summon their personas.

"Our Personas?!" Yukiko yelled as Sakuya throw Maragidyne and Kintoki-Douji was thrown to the group by Mirror as Leo, Mona, Iggy and Arval block with Magic. "First our Shadows... now this?!"

"Grrr! Teddie is gonna file a copycat complaint!" Teddie form a drilling attack against the Mirror Juna but she block.

Aqua use Spellweaver to gather the Mirrors together as she spun around, attacking them and then Marth raised his sword for rapidly dash around Aqua's Spellweaver and then leaps into the air with his sword raised, and lands with a powerful overhead slash to the ground. The Mirrors were pushed away as Mirror Butterfree throw Hurricane toward them, covering some of their eyes as Mirror Venti fired multiple homing shot arrows to the group, hitting them as Zhongli form a barrier to block off attacks. Zhongli then dash in superhuman speed and struck each Mirror self while Mona created a dome to pull the Mirrors and trap them.

Ryoma, Rean, Levi and Felix each ran up to slash the dome to deal a large explosion as Fie lunged and clash with Mirror Lea and they swing at each other, then the real Lea airstep and lash out series of slashes on him while Qrow and Mirror Qrow swing at each other.

Both Qrows pass through each other as Hollow Celine throw a fireball at Qrow which he rolled while Naoto Shirogane firing bullets at the other who deflected them with a couple of swings before lunging at him. Morgan got in front and they swing at each other until Morgan throw a fireball to knock him away and then Leo summon multiple black holes to pull the Mirrors together. Quaquaval throws Hydro Pump at him.

"Ngh!" Leo grunted, canceling the attack as Mirror Tiki breathed fire while other Tiki did the same. Laura lung at rapid speed and she swing fierce against the Mirrors as Lissa swirl her axe to form tornados and then knock it toward Mirror Qrow, pulling him as Lucina ran up to Mirror Yukiko to slash her.

Mirror Yukiko block and then swing with her fan as Lucina dodges then rapidly thrust her and then knock her away. Levi use Spiral Vortez to pull them together as he launch to the air and impale them with glave energy spikes, then Rean, Juna Lea, Aqua, Zhongli, Emblem Crow, Emblem Erika, Emblem Roy, Mickey, Marth, Qrow, Leafa and Ryoma slash each one while Weavile form a drill attack with Night Slash, Butterfree use Hurricane to blow them away, Quagsire throw hydro pump at them and Arval trapped them within a dome and then deal with explosion.

The Mirrors fell on the ground, revealing to be machines as they deactivate.

(BGM ended)

(Resuming Maliciousness in the Mirrors)

"Well, would you look at that." Emblem Crow fold his arm.

"As I suspected. They are machines." Naoto Shirogane narrowed her eyes. "It's just like the Fake Arios you've encountered. We're in the enemy base of operation all right."

"Well, this was a fine welcome party." Venti sighed. "Now we know what the EDF was in Mishelam for."

"Oh yeah. They said they were told to keep an eye on something, right? Does they mean this?" Lea asked

"It's possible, but there are still a lot of questions that need answers." Emblem Rean fold his arms. "All we can do is stay alert and keep going."

"That isn't the only problem we need to be aware of. Those machines were able to use Personas." Naoto Shirogane pointed out.

"Yeah. But is that even possible?" Yukiko wondered as she gasped. "Could it be... they have Plum of Dust in them?!"

"Plum of Dusk?" Leafa asked

"It's a material with special properties." Naoto Shirogane explain. "It the core of how the Anti-Shadow Suppression are made and allows them to use a Persona. But for them to create a replica of our Personas... No... could it be possible our arrival was predicted?"

"Like they knew we would be coming?" Amia asked.

"But how can that be?" Felix asked.

"I don't know for certain but... I've got a real bad feeling about this..." Naoto Shirogane muttered

"I'm almost having trouble sensing things too." Mona replied. "This place is more and more dangerous the further we go. Please be cautious everyone."

"Right!" Venti nodded as they kept going as Rean look at the Mirror one more time as Levi noticed.

"Rean, you coming?" Levi asked

"Y-Yeah. Sorry. Right behind you." Rean replied as he walked.

But the moment they left the hallway, the Mirror suddenly shifted and turn black.

"Sheesh, this place reminds me of my home before it transforms into Dark Beauty Castle..." Oswald muttered.

"Yeah... That's where we fought against the blot..." Mickey trailed off.

"This domain is unlike any I've seen before... I shudder at the thought of whoever created this." Leo muttered.

"Yeah. But who could have that power?" Qrow wondered as they reached the hallway until they heard something shift. "Huh? What was that?"

"Damn!" Ryoma yelled as he looked down and they all fell through the trap door.

(BGM paused)

They all fell in a dark room that is pitch black.

"Where are we?" Rean wondered "Hey, is everyone all right?"

"I'm fine!" Celine said as she conjured a ball of fire to light up the room.

(Trails into Reverie ost - Mysterious Elements)

"Whew, what a relief." Rean sigh of relied.

"Hmph. Cats always land on their feet, remember?

"Heh, so the saying goes." Rean smiled before he thought for a moment. 'But why does it feel like my senses have been shut off?'

"Goodraaa!" Goodra cried as he hugged Rean and sobbed.

"Haha. It's okay, Goodra, I'm here." Rean meeting him.

"I take it that means you're both in one piece?" Crow asked, bushing off the dust off of him as he approached with Weavile. "Glad to hear it... but it looks like we've been separated with the others."

"No kidding." Aqua said as she, Levi, and Zhongli approached.

"Aqua! Zhongli! Levi!" Rean smiled and sigh with relief.

"Thank goodness you guys are okay." Levi sighed of relief. "But hey, did you notice I can't sense anyone else but us?"

"Something really is blocking our senses... I just hope everyone is okay..." Aqua muttered

"Not much we can do but split up and look for an exit." Crow advised

"Right. Come on, there's got to be a way out of here." Levi agreed as they split up and being to examine the room as Levi touching the walls. Celine look around and then in the mirror, there was Crow who had his Orbal Pistols out and aim at Rean.

Celine turn around and see the Crow in the mirror.

"Rean! Behind you!" Celine yelled as Rean flinched as he tried to dodge the bullets but then Levi turn and lung at him with his Glaive out, only to be blasted by the Levi within the Mirror from a light beam.

The bullets passed Rean, and hit something else. Rean turns and sees Crow, Goodra, and Weavile tries to attack him with his double saber.

"Crow?! Levi?! Goodra and Weavile?!" Rean exclaimed as he see static on his head along with Levi and Weavile.

Then the Crow, Levi, Goodra and Weavile emerges from the mirror.

"That's not us, Rean! Those are fake! We're the real ones!" Levi yelled

"It must've tried taking the place of the real Crow, Levi, Goodra and Weavile during the chaos of our little tumble!"

"I knew something was amiss." Zhongli got his Spear out as Rean jump back with his Tachi out.

"You seriously saved my hide, Crow, Levi." Rean said.

"Heh, we almost—fell foul of the traps ourselves." Crow smirked

"Crow, did you hang out with Yang?" Levi giving him a deadpan look as Laura, Fie, Quagsire, Scizor, Polteageist, Quaquaval, Aqua, Shez, Mickey, Mona, Arval, Marth, Iggy, Leafa, Ryoma, Lucina, Lissa, Morgan, Amia, and Felix were knocked away with sparks on them.

The other Juna, Venti, Laura, Fie, Aqua, Lea, Shez, Mona, Arval, Leo, Marth, Tiki, Iggy, Qrow, Leafa, Teddie, Yukiko, Ryoma, Naoto Shirogane, Lucina, Lissa, Crow, Morgan, Amia, Mickey, and Oswald came out from the mirror with Poltergeist, Quaquaval, Butterfree, Quagsire, and Scizor.

"There you are!" Emblem Erika sigh of relief.

"We ended up in another similar situation." Emblem Micaich muttered. "But I'm glad you all are okay."

"Talk about a close call, though." Rean said as they turn to the fakes.

"Grrr! We're really up against some tacky wiseguy!" Lissa growled

(BGM ended)

"Come on, let's show these imposters who's boss!" Lissa yelled

(Resuming Night of Tragedy)

The Fakes eyes glowed red and a dark aura cloak them.

"Ngh..." Aqua clench her teeth. "This is exactly like the realm of darkness! Let's go, everyone!"

The Fake Fie, Scizor, Leafa and Felix lung toward the real ones and they block and counterattack as they swing at each other while Fake Ryoma lung toward Ryoma and they clash their swings, swinging at each other fiercely as Fake Aqua teleported and then throws ice crystals at the group with Fake Mona closing them in with a water wall and Fake Quaquaval used Liquidations as water swords and lung toward Mickey.

Mickey swing against the Fake as Mona spread her arms to create jet of water to push the wall while Celine and Emblem Vita combine their magic to rain down fire and ice rays onto the Fakes as they split up. Fake Quagsire throws Earthquake to the ground, hitting them. Arval cast Hades to pull them together and then Lissa swing against her Fake.

Both fake and real Marths swing their swords at each other while Fake Morgan throw Magic onto the ground as the real Morgan respond in kind. Fake Lucina rush to swing her Falchion against Celine, but she jumped and kick her face while the Fake Crow swing at her, but Emblem Vita block it and Celine claw his face.

Emblem Eirika thrust combo Fake Iggy who used his arms as a shield and then flip kick and ten throwing magic attacks on Lissa. Lissa backflip while Levi ran up and then swing fiercely as they both swing at each other until Fake Iggy curl into his shell and moved around Levi until swing to hit him, but the moment he did, the Fake Iggy hit his back. The Fake Mickey rian down light attacks onto the group as Lea swirl his Keyblade as a spinning shield overhead.

Juna rush to Fake Mona to punch her, but she backflip and cancer her spell and then throw a swift kick at Juna as she block. Venti jump high and then firing orbal shots against the Fakes, but Fake Aqua form a barrier to reflect them back at him. The real Aqua and Emblem Crow swing against the fake and knock her away while Rean and Emblem Roy swing at Fake Ryoma until The fake kick Rean off and slash him, but Emblem Roy and Rean block the attack and push him off as the real Crow firing on the Fake's face and then Weavile and the Fake throw Night Slash at each other until the Fake kick the real one as Goodra used Dragon Tail to knock him away.

Emblem Micaiah throw rays of Thani as Polteageist throw many Shadow Balls onto the Fakes as Fake Marth slash one but the real Marth rapidly thrust him. The Real Mona created a field of water of the starry sky and then raised her arms to trapped the fakes in a bubble as Yukiko, Teddie and Naoto Shirogane throw Megidolaon, Maragidyne, and Mabufudyne.

The Fake Juna firing Bullets toward the Team as Zhongli spin his spear into a spinning shield and then Zhongli wave his arm and throw stone pillars toward the fakes, pinning them to the wall and then Leo summon three roots to bind them and then slam them to the ground as Tiki breathe fire on them and Celine and Emblem Vita throw Lost Genesis on them and deal devastating damage, causing them to malfunction and stop working.

(BGM ended)

(Resuming Maliciousness in the Mirrors)

Mona wipe her forehead. "Phew. At least we dealt with those fakes." Mona said.

"It's a strange feeling having to fight yourself." Fie replied.

"They're clearly well-made. It's difficult to tell the difference between who's real and who's false." Emblem Vita fold her arms.

"Yeah. I heard that imitation is the best form of flattery but this is creepy." Lissa grumbled.

"Incidentally, don't think I didn't notice you trying to smash my face off back there, Lissa. As well with Celine claw, too." Crow place his hand to his lips, looking at the two.

"Hey! That was your fault for mixing ME up!" Celine yelled.

"Whaaaat? I don't know what you mean~" Lissa giggled as she causally wrap her arms behind her back with her axe. "Besides, I have no reason I wanna kill my son-in-law."

"Wait, you want to kill my Husband, mom?" Morgan fold her arms.

"Again. Nope. Besides, the REAL Crow would have no trouble dodging my attacks after all the shenanigans we've done in the past."

"Now ain't that sweet. You really trust me that much, huh?" Crow asked sarcastically.

"Oh, but of course. I always trust you. Unless you call me delicate then I don't trust you." Lissa place her hands on her hips with a sulk.

"Sheesh, you're not gonna let that comment go, aren't you?"

"Well, joking aside." Lea scratch his hair. "This place is too dangerous. We're lucky we memorized each other well enough to tell the difference. Now come on. Let's get out of this hellhole."

"Agreed." Ryoma nodded. "Between the traps and whatever is jamming our senses, I'm not too fond of this place. But I don't think we're far from the top floor either."

"Yeah. Let's get out of here before something else shows up." Oswald agreed as they keep going.

As they did, Rean stopped and turn around to the Mirror behind him for a moment until suddenly, a Giant sinister eyeball appeared on the Mirror.

"!" Rean flinch as the eyeball narrow its eyes as it was smirking.

Rean draw his Tachi and the eyeball disappeared, as it was never there.

"Rean, what's wrong?" Mickey asked as they all look back.

Rean sheath his tachi. "Sorry. It's nothing."

As they take off, the giant eyeball appears within he mirror again, grinning and then vanishing as Rean glance back, grit his teeth and keep walking.

"As I thought, it seems our enemy anticipated our arrival." Naoto Shirogane muttered.

"But that doesn't make sense. How would they know we would be coming, and create copies of us?" Venti wondered.

"I don't like this. It's like we're playing right into somebody's hand." Rean muttered.

"Agreed. This level of foresight is uncanny. There's absolutely no way for them to know who's gonna be here." Leo agreed.

"Yeah... What kind of monster could have this level of power..." Aqua muttered as they keep going until they enter a room with mirrors.

"And now we're in an area with mirrors. Great." Oswald sighed. "So now what?"

"Hmm. Let's examine the room, but remember to be careful." Mickey advised as everyone nodded and then begin to look around and examine the room.

But the moment Oswald touch the mirror, a portal from it pull him in.

"Whoa! Guys!" Oswald yelled, getting their attention as Oswald pull his hand out.

"What's up, Oswald?" Fie asked

"Look!" Oswald touch the mirror, revealing the portal.

"A portal?" Celine asked.

"This could be a trap." Tiki pointed out.

"If it is, then we should avoid taking that mirror." Marth advised.

"But there's no way forward, right?" Shez asked. "The other Mirrors seem to be... just mirrors."

"So this mirror is our only way forward then?" Arval asked. "It seems we got no other choice but to go through with it."

"Right. Everyone, let's be careful." Zhongli agreed as hey go into the Mirror.

(BGM ended)

As they all arrived on the other side. They all saw the very different area.

(Kingdom Hearts: Birth By Sleep ost - Night of a Dark Dream)

The area they found themselves in was a central chamber leading to a hallway. The background was a

"What... is this place?" Fie look around.

"..." Aqua stare in the distance.

"I don't think... we're inside the Castle of Mirror anymore..." Juna looked around.

"Are we... in a different location?" Lucina asked.

Mickey notice Aqua's grim expression.

"Aqua, what's wrong?" Mickey asked.

"This place... it reminds me of the World Within the Realm of Darkness." Aqua muttered. "Although the interior is different. But if my guess is correct." Aqua turn her back to the mirror behind and touch it. "As I thought. This was a one-way entrance.

"Wait, you mean we're trapped here?" Amia asked in with a surprise.

Mona activated her scryglass and begin ticketing.

"Ngh. No good." Mona muttered as she deactivated the scryglass. "Whatever this phase space we're in interfering with my scryglass. I can't make heads or tails of this place."

"So now what do we do?" Lissa asked

Marth look at the hallway. "Well, there is only one path forward. Perhaps we should make our way there."

"Sounds like it's our only option then. Come on. Let's see where this will lead us." Venti replied

"Right. But remember to be careful." Rean said as they begin to head to the hallway until.

The moment, they walk into the hallway, they spotted a Mirror in the end.

"A mirror?" Zhongli rub his chin. "No... another gateway."

"Shall we find out where it leads?" Levi wondered as they all look at each other and nodded.

They approach the mirror and the mirror added some zoom-in effects, transporting the group into a terrain of blue glowing marks on the ground.

"..." Aqua looking around.

"No way..." Mickey grimaced.

"I assume you're familiar with this terrain?" Emblem Micaiah asked

"Yes. This is what the realm of darkness looks like when I was exploring. Are we back in the realm of darkness?" Aqua wondered as they keep wondered.

"No... or at least. I don't believe so. It should not be possible to access the realm of darkness through the mirror... and yet..." Zhongli wondered.

"You're recalling what Xemnas mention with the Dark Star back in the Keyblade Graveyard, right?" Rean asked

"Yes. To think other methods can be use to travel to this dreaded place of hollow..."

"No wonder this place has a certain level of dread here..." Celine muttered. "I was even more shocked that you've survive here, Aqua."

"It wasn't easy, I'll give you that." Aqua struggled.

Then a couple of Shadows, Neoshadows and Darkballs appeared.

"Oh, look! We got a couple of Heartless to smash!" Iggy smirked.

"All right, let's clean those monsters." Qrow readied his Harbinger and then he long and slash a couple of them and Yukiko summon Sayuya to spin rapidly with fire and pull them into a tornado as Aqua swing her Keyblade in a cartwheel to hit rid of them as they keep going.

"How could the Castle of Mirror somehow have access to the realm of darkness?" Juna wondered as she scowled.

"It should not be possible for the Septium Veins to possess that level of power. Another force is in work here." Zhognli replied.

"But who would have that level of power?" Lucina wondered.

"Whoever they are... must be sick in the head." Crow muttered as they keep going.

"Hehehe..."

"Oh boy, more children's laughter..." Morgan groaned

"Ahaha..."

"Augh! I did NOT sign up to be in some horror show!" Leafa scowl. "The last time I ended up in one was when I was in the Underworld and I've been inter situations that gave me death all over."

"Wait, you mean you suffer pains that is death itself?" Fie asked.

"Imagine your arm was cut off and then you get impale in your eye."

Laura grimaced. "Oh, Aidios! How did you manage to survive that?!"

"It's a long and painful story..." Leafa muttered. "But I've used a "goddess" account where I have unlimited rejuvenation. So no matter how much I'm hurt or how much pain I've felt. I can't die out. There was a lot of hell from a dirty scheme involving some group to allow people diving into the Underground—thinking it was a game— and end up ruining a lot of work Kirito's work company."

"Still, to endure that much pain takes a high level of mental training." Ryoma spoked.

"I was nowhere near the level of mental training. But it was my thought for Kirito stubbornness to help me push it though."

"You are one tough woman, Leafa-san." Yukiko smiled yet sadden.

Teddie spotted a Mirror in the distance. "Hey, look! There's another Mirror!"

They approach the Mirror and then it transported them to another realm filled with a large room with a mirror floors.

"Where are we this time?" Laura wondered as they look around.

"Another area, but this time with a mirror floor." Lea looking down.

"Hmm..." Aqua hummed. "Come on. Let keep going."

As they keep wondering around the large room, they encounter more Shadows, Moon Guardians, Neoshadows, and Darkballs within the area and they've taken them out and keep going until they encounter stone pillars. Zhongli make a note of this as they keep going until they look around and see more of a stone pillar.

"Hmm... A moment." Zhongli approach the pillar and press it, causing it to glow. "As I thought. It would seem some of the pillars here are in mechanism order. If we can leave this realm."

"But how are we gonna solve that riddle out?" Amia wondered as Emblem Rean look down the floor.

"Perhaps the floor will be our clues." Emblem Rean said.

"Right. Let's first look at the floor and then the pillars and see if there are some differences." Rean said as they begin to explore around the room later and Mona notice that the mirror has stars flickering.

'Stars flickering... could it be...?' Mona thought as they walk around until they found different pillars mechanism scattered around. "Ah. I think I solve the puzzle to this realm." She alerted her team. "The stars in the mirror floor the number that needed to be pressed. So if we connect them in order... we should open a way out of here."

"All right, then let's get to work." Shez said as they split up and looking for the correct pillar number as Arval activated the first one, then Leafa, Levi, Crow, Teddie, Iggy and Lea.

The large room begin to flash, forcing everyone to cover their eyes and they spotted a Mirror.

"It appears we've solve this riddle. Let us continue." Tiki said as they keep going and approached the Mirror.

(BGM ended)

The Mirror transported them to a ghost-like arena area where the backdrop has dark clouds and dark green fire around.

"Well, this is just getting spooky." Fie sighed.

Something slithering in the darkness as it move swiftly until Zhongli turn his head.

"Look out!" He summon his Spear and throw it neat Mickey.

"Wha!" Mickey ducked as something hit what was going to attack him.

(Epic Mickey ost - Phantom Blot)

As they all draw they weapons and took their stand, a large shadow emerges from the ground and reveal to be then Phantom Blot who unleash a roar.

"Ah! There he is!" Oswald yelled as he pointed. "It's the Blot!"

"So it is here..." Mickey summon his Keyblade as the Phantom Blot flew into the air and then gathering dark energy and spread out its arms, causing the arena backdrop to change into a dark vortex as Phantom Blot roared at the group.

"This one looks like it's gonna be a tough fight! Everyone, prepare for battle!" Rean yelled

Zhongli throw his Spear gleaming with power and pass through Phantom Blot which force him to jump as Phantom Blot pieces the ground.

"My lance pass through it?" Zhongli resummon his lance as Phantom Blot bursts out of the ground and throw a jet of jink. Zhongi form a barrier to block the attack as Mickey airstep and combo slash it.

Arval throw Misama with Morgan throwing Elwind. Phantom Blot shield itself with its arms and then flew into the air and then channeling dark energy to throw toward the group. Aqua shotlock it and fired Prison Rain as Crow switched to his pistol and then firing Homing shots. Phantom Blot move around to avoid the sits until Levi lung high enough to swirl hig Glaive fast enough as a propeller and slash through the Blot and then throw a kick, but its liquid body begin to absorb his feet, causing Levi to blast a jet of light to splash off the paint and he backflip and landed on his feet.

"Its body is made out of black paint. Be careful not to get some stick on you!" Mickey advised.

"Shouldn't you tell us beforehand?" Levi asked.

"Complain, later, Crimson Slash!" Rean throw Supreme Crimson Slash on Phantom Blot as it circle around it and then throw dark energy rain toward the group.

Mona cloaked her hands with magic and then fired stream of water toward the left Phantom Blot. The Left Phantom Blot dodge it while the right Phantom Blot throw a jet of pink at her, but Mona teleported herself out of there while Leafa throw Zeruel Cannon on the right one. Lissa switch to her Bolt Axe and fire lighting at the right Phantom Blot and then ti flew down to grabbed her.

"Hey, let go of me you blech thing!" Lissa swing her Bolt Axe on the body and shocking electricity on it as it throw Lissa. "Waaaah!"

Lucina jump in and jumped her. "Are you okay, Aunt, Lissa?"

"Never better!"

The left Phantom Blot raised its arms and throw a black ink bomb toward while the Right one open its mouth and fire a jet of black ink as the group dodge, then Venti aim his hand and then fire two spheres of magic toward the Blots and hit their heads as they groaned, then Felix imbued his sword with magic and then le long toward the Left Blot and deal slashes around its body and then slash its back as it groaned. Laura on the other hand jumps up and then slashes through it, and then flip and swing down, only for her sword to pass through it.

As it laughs, Aqua throw Ice Crystals around its body, freezing it as it shoves and then Mickey throw Triple Firaga while Oswald with the ARCUS Alpha in hand throws Fire Bolt. The Phantom Blot hissed as he two blot fuse back together.

The Phantom Blot fired a dark green ray toward the group as Quaquaval jump up and used Aqua Step on its face and then bounced off while Goodra fire dragon pulse on it. Rean and Emblem Roy jump up and then aerial combo slash it but its body pass through it.

"Ngh!" Rean backflip and landed on its feet. "Physical Attacks won't work on it. Guess we have to rely on Arts and Magic to defeat this thing."

"It's like Juvia's water magic. Or Noel's powers." Levi remark.

"In that case." Mona cloak her hands with magic and them throw water blades toward Phantom Blot. "Aqua, can you freeze it?"

"Got it!" Aqua nodded and then summoned multiple ice crystals and then throw them at the Phantom Blot.

Phantom Blot shield itself and then Teddie summons his Persona for Mabufudyne. The Phantom Blot swing its arms to firing multiple Homing Shots toward the Team and then flew and dive directly at Rean. Rean jump high to avoid the attack and then Phantom Blot spreads its arms to summon portals, and reach its hands to create more portals of its hands punching the ground. The Phantom Blot laugh as it raised its arms and channeled a large black energy sphere and throw it into the air. It shattered, raining down dark spheres to create black ink bombs to cover the ground as everyone dodge. Mona used her magic to create a wave to move them.

"All right, begone!" Mona then summoned two magic circles and them fire streams of water and split on Phantom Blot as it roared in agony until it washed away.

"Well, at least we're done." Lissa sighed. "Not much for some of us can do..."

"Yeah. But at least it's over." Mickey said and a Mirror appeared. "There's our exit. Let's go."

The group made their way to the mirror as it flicker with light and then it transport them to the top floor of the area.

(Kingdom Hearts 0.2 Birth by Sleep -A fragmentary passage- ost - The World Within)

"Looks like we made it to the top floor... However..." Mona paused

"Indeed. We're not alone in this dimension. Which as I suspected." Zhongli nodded. "But there's more, there is an alarming amount of spiritual energy within the air."

"Yeah, something clearly extracting it directly from the spirit veins!" Celine nodded

"So we can thank this place for distorting the spirit veins, huh?" Crow asked.

'It's just like the events from years ago...' Juna thought.

"It appears to be a dead end, but we can't let that halt our investigation." Laura said as the group nodded as they walked up the stairs to the large mirror.

"What's with the giant mirror?" Iggy asked

"Oh, great. Please tell me this one isn't going to be a trap like the others." Venti hoped.

"No. Not this time at least." Lucina sighed. "At least I've hoped."

"The SSS told me all about this mirror! They said that there's a hidden room on the other side, where KeA awakened to her true power!" Juna said.

"What do you think waiting for us on the other side?" Shez asked.

"Most likely the "God". Marth answered.

"For an amusement park, they sure know how to make it spooky. It's a perfect place for a hideout." Leo said.

"I believe this is also where Arceus, Dialga, Palkia, Giratina and Celibi made their way to Crossbell before the SSS were arrested if I recall." Zhongli replied.

"From two years ago, right?" Levi asked

"I'D heard about the events of two years ago, but obviously I wasn't involved directly with Crossbellans. Even do I get the feeling that what's going on here is specially modeled after that event."

"Then we need to be careful who's also on the other side. They might be formidable." Arval added.

"Right. So we should—" Rean approached it until Levi, Mona, Emblem Vita, Zhongli notice something amiss.

"Wait, Rean! Don't touch it!" Levi reach out his hand but Rean was suddenly pull into the Mirror and disappeared, dropping the Ring of the Young Lion.

(BGM ended)

With Rean...

Rean open his eyes and found himself into a black void.

"Ugh... Is this some kind of spiritual trap?" Rean groaned as he look around. "Juna! Venti! Levi! Celine! Vita! Micaiah! Emblem Me! Laura! Fie! Aqua! Lea! Shez! Mona! Arval! Zhongli! Leo! Marth! Tiki! Iggy! Qrow! Leafa! Teddie! Yukiko! Ryoma! Naoto! Lucina! Lissa! Crow! Morgan! Amia! Mickey! Oswald!" Rean look at his hand and had an ! over his head and see the Ring of the Young Lion is gone. "Ah! Roy!" He look around. "Roy, where are you?"

"I think this is as far as we can go." A voice respond, causing Rean to gasp immediately as he look in front of him.

"Sorry we couldn't make it to the end with you." Another voice was very familiar as it reveal to be Millium in her astral form and Crow stand next to her, looking with a smile with a sad expression.

(Trails into Reverie ost - Crime, Punishment, and Deceit)

"What?" Rean eye widen with a sweat rolling on his cheek. "Crow? And Millium... that form... It's... just like..." The two latter vanished. "W-Wait!" He reach out but too late.

"Rean..." Another voice cried as he turn and see Elise with her Bellossom, Meganium, Metagross, and Tinkaton were in tears. "You can't have..."

"B-Bell..." Bellossom sobbing along with Meganim, Tinkaton and Metagross with Alfin wrapping her arms behind Elise, crying alongside with her with her Gardevoir, Dragonite, Sylveon, Frosmoth, and Aurous.

"Rean... *sob* How? How could you...?" Alfin sobbing

"Elise... Your Highness..." Rean trailed off until they vanished.

On his right, was Levi on his knees sobbing with Flygon, Altaria, Rachu, Polteageist, Leavanny, Baxcalibur, Charizard, Greninja, Decidueye, Meowstic, and Goodra crying.

"Rean, you bastard! How could you?!" Levi sobbing uncontrollably. "You promise... *sob* you... promise. You... stupid... promise-breaker!"

"Levi..." Rean reached out his hand to him, his Pokemon, and Levi's but they vanished.

"ROAAAAAAAR!" Charizard cried as he roared.

Rean expressed a dreaded feeling as he turned his back and see everyone from Class VII, old and new, Kingdom Hearts Crew, Smash Bros fighters, Fodlan, Mushroom Kingdom, Blazblue group, RWBY and JNPR, Galar Gang, and Rigbarth friends all looking at the sky with a tearful expression.

"Rean! REAAAAAAN!" Alisa screamed, reaching out her hand in the sky.

"Why? Why?!" Juna cried.

"Nooooooo!" Elliot cried

"Rean! Come Baaaaaaack!' Towa cried.

"Ahh... Aaahahaaaa!" Peach cried with Mario comforting her.

Rean shuttered at he see all the people he love and adored in his heart, vanished from his fight, causing him to grit his teeth, even shedding a tear as it rolled down on his cheek.

"This is the end you should have faced, Rean Schwarzer." A malevolent Voice spoke. "Accept it."

Rean lower his head. "Maybe you're right." he spoked, unknowingly, someone was behind him with a sword in hand. "If I'd made even one mistake, this is how it could have ended. But even so..." Rean clench his fist. "I refuse to accept it. That is not my story. I will cut down this ignoble end!" He draw his Tachi to turn his back and swing against the mysterious assaulted from behind and made them disappeared.

Rean then turn to the direction in front of them and then swing, shattering the mirror and burst out of there.

(BGM ended)

"Rean!" Levi yelled as the Team regroup as he hug him "Oh thank god you're okay!"

"Are you trying to give us a heart attack?!" Lissa complain.

"Sorry, about that guys." Rean hug Levi back. "It was careless of me not realizing it was a trapped."

"Heheheahaha." A dark crackle interrupted them as they turned to the direction of the voice and see Mephlies the Dark.

(Sonic the Hedgehog (2006) ost - Mephlies Whisper)

Mephlies was clapping his hands slowly as in a form of mocking. "Well done. All of you. I should commend you for making your way here. And of course, a special congratulations to you, Rean Schwarzer. For surviving that trap that was set especially for you."

"So you're the one behind those illusions?" Rean giving a glare as he gritted his teeth. "Every one of those illusions was sensitive to me."

"Wait, what did you see from that spiritual trap?" Celine asked

"I remember Millium was in that astral form during the Great Twilight. And Crow disappeared with her. Along with mourning about me."

"Wait... you mean... Your... "death"?" Levi widens his eyes with shock.

"Ah, yes. "That" particular event never happens in this story. But it is just something that was—"

"Enough with the details, Mephiles."

Everyone had an !? over their heads.

'Was that... my voice?' Rean thought as they all turned to the direction of the voice.

"Ah. Apologize for the loose tongue." Mephiles turn to the voice and did a respectful bowing pose.

They all see someone back. While their appearance is a mystery, they can see long overcoat of black and white with belt attachments similar to Rean's coat. He wears block trousers.

"But just like Mephiles. I'm impressed that you all managed to make your way here into this temporally castle of mine. How did you enjoy the interior? Did you enjoy it? Especially that little "Detour". I put a lot of effort into it, you know. Oh. Especially your "entertainment" Hmhmm..."

"W-What the hell?" Juna grits her teeth. "Who the heck are you?! You're the one who changed the interior to the Castle of Mirror!? And why do you sound like Instructor Rean?"

"That's one of the questions you wanted to ask? Yet you realized my voice is no different to that of Revali or Diluc."

"He's... got you there." Venti said.

"As for the Castle of Mirrors. Why not? After all, the Crosis Family did use this castle to further their Azure Zero Project. That's how the abomination of alchemy was able to gain her power as a Sept-Terrion of Zero, didn't she, Juna Crawford?"

Juna flinched "...!"

"Reusing this castle's true form—" The figure turns to face the group, revealing their face, except that his face was protected by a mask but the face is nearly identical to Rean. "—is by no means different."

With the Full appearance revealed, their mask aside, their appearance was already described by the long black and white overcoat. He has a flared collar and a loosely worn mixture of black and red belt. His black zipped shirt over a white buttoned shirt and his black trousers. His leather laced-up boots are black.

"What the—?!" Venti gasped.

"Whoa! He looks like Rean!" Iggy exclaimed.

"Another fake?" Ryoma asked. "Wait, no... something different about him... And I don't mean his appearance."

"So he must be the 'True God of the new universe' we were warned about." Rean asked

"But that's a bit far-fetched, don't you think?" Shez asked. "I mean, since Rean claimed himself to be a god?"

"I doubt Rean would like to be put on a pedestal." Lucina struggled.

"Are you kidding?" Crow chuckled. "For him to call a—"

"..." Chaos Rean stared at Rean, then glaring underneath his mask as he grit his teeth. "..."

A strong murderous intent washes over Rean.

"!" Rean flinched as he nearly took his battle stand.

"Rean?" Levi look at him, looking surprised.

"Rean, what's wrong? You almost draw your sword." Laura asked.

"I'm not sure. I almost felt an intense bloodlust just now..." Rean muttered. "Enough to scare me for my body to react on its own."

"Are you all done with the ridiculous chit-chat of your friend being a god or not?" Mephiles asked with an exasperated sigh.

"Pay them no mind, Mephiles." A voice spoke as a corridor of darkness appeared. "That is how these fools enjoy their measly time before their deaths."

"That voice..." Aqua grits her teeth.

"Oh hell no. Is that you, Xemnas?!" Lea growled as The cloaked figure lowered their hood, revealing to be Xemnas. "Oh, god damn it!"

"So, Organization XIII really is back." Fie growled.

"Please don't tell me that Xehanort made himself into a portal for them to come here like he did before." Crow muttered.

"Knowing how Xehanort did it. It must be that." Rean said. "And yet, it makes no sense. Especially if Xehanort has done his "reception arc". But I doubt they'll be interested in talking. Especially him." He referred to Chaos Rean.

"All right, who are you? Identify yourself!" Ryoma depends.

"Hehehe..." Chaos Rean dark crackled. "I have no interest in obliging to your question. You are quite bold to dare ask me that, King Ryoma. You must not value your life as a select group of people. No matter. Allow me to welcome you all to your death."He said as he snapped his finger and Zoa Balor appeared next to him.

"Isn't that Zoa Balor?! Alberichs's Combat shell?" Lucina asked

"I remember Aether destroyed that thing. It's been repaired?" Levi asked

"From the looks of it, yeah. But nothing is rational about this." Rean muttered

(BGM ended)

Rean draw his Tachi. "Steel yourselves for a fight, everyone! Whoever our opponent is, he clearly has the answers we need if we're to get to the bottom of what's happening. We need to take him in!"

"Right!" Fie nodded as she and everyone else got on their stance.

"Then let's do this!" Venti smirked.

"Cute." Chaos Rean roll his eyes behind his mask. "Mephiles, Xemnas, Zoa. Kill them."

"As you command." Mephiles transforms into his battle pose as Xemnas summons Ethernal Blades.

Mephiles snapped his fingers and the floor turn into a pool of darkness, causing everyone's heads to have an !? over their heads.

(Sonic the Hedgehog (2006) ost - Boss Mephiles)

"What the—the floor!" Lissa gasped.

"Now, my Shadows." Mephiles smirked behind his no mouth as hordes of Shadows appeared. "Dance!" The Shadows jump to the group.

Zhongli raises his arm to summon a stone pillar to launch Xemnas into the air. Before he can respond. Mephiles snapped his finger and manipulated time to rewind to the point where Xemnas was struck by Levi. The Glaive made a U-Turn until Mephiles teleported and then fired a jet of energy to bounce off the Glaive as Levi use magic to teleport it back to his hand.

"It's time we've drown you all to darkness!" Mephiles smirked a she dive into the pool of darkness, and then transform into a monstrous form.

"What in the Naga's name is that?!" Lissa yelled.

Mephiles roared and fired a massive leaser toward the group as they split up. Rean lung toward to slash Mephiles's body with Emblem Roy and Levi throw a beam of light with Emblem Micaiah.

"It's time we finish this." Mephiles raise his arms to gathering dark power something burst out of the smoke, revealing to an energy shot. "Ngh!?" He bend his back to avoid the attack as the smoke disburst by Venti who eyes glow.

Venti swirl his arms as onslaught green rays aim toward the trio until Mephiles, Xemnas and Zoa Balor teleported to avoid it. Venti snapped his finger to rewind time to return Mephiles, Xemnas and Zoa Balor reappeared to where they were.

"What?!" Mephiles eye widen.

'How did he...!?' Chaos Rean grit his teeth as Venti fired the onslaught of rays at them.

Chaos Rean teleported in front of the ray and aim his hand to form an invisible barrier as a destructive explosion covered the room until Venti cleared it away.

(BlazBlue ost - Premotion)

"What?" Venti's eyes stop glowing as he look surprised. "He blocked it?!"

"Hah... I was not expecting you of all to manipulate time." Chaos Rean muttered. "Are you three all right?"

"Yes. Thankfully." Mephiles answered as the four of them landed on their feet.

"The three of you fall back. I will handle this."

"As you wish." Xemnas responded as he, Mephiles and Zoa Balor step back and jump toward the machine behind them.

"Ah, so the "true god" decided to fight us this time, huh?" Crow asked with a smirk.

"Heh. You're just as cocky as ever, Crow." Chaos Rean responded

"Huh?"

"Caution everyone." Zhongli said. "I don't know how he managed to block Venti's attack, but he's clearly someone we should be more cautious."

"Indeed. Xemnas, Mephiles and Zoa Balor are formidable against our large numbers, but we don't know what this... fake of Rean is capable off." Laura agreed.

"Yeah. I don't know why he looks like that either. The white hair reminded me of that time when Rean was during the Great Twilight." Fie agreed.

"Yeah... and yet..." Rean close his eyes before he look firm. "Everyone, I want you to leave him to me."

"Huh?" Lea blinked as they all turn to him.

"Wait, you want to face him alone?" Aqua asked in surprise.

"Ho?" Chaos Rean dark grin.

"Yeah." Rean glancing at Chaos Rean. "I get the feeling that out of everyone here, it's me you are mostly interested in. That bloodlust that I've felt earlier. I doubt it came from Mephiles or Xemnas. It can come from you, and only you."

Chaos Rean snickered. "Hmhmhmhm... Oh, I couldn't help myself. But it's so kind of you where your friends will be the spectators. How can I resist this offer? It would be foolish of me to just let this slide. I'm going to enjoy this." He then summon the Tachi of Chaos.

(BGM ended)

"..?!" Zhongli flinched along with Venti, Levi, Mona and Celine.

"He summon a Tachi from magic?" Celine asked

"No... I've sensing an unknown power. Is it from that weapon... or the wielder?" Mona wondered.

"I don't know... but something tells me this... version of Rean... is someone that causes me dread." Emblem Vita muttered.

'What is this feeling...?' Rean thought as a swear roll down on his cheek. 'Am I... afraid of him? My body screaming at me... telling me to turn back... and run. But I don't know why. This is far worse than with the Fake Arios.'

Rean felt bloodlust from behind, causing him to react to quickly draw his Tachi to swing and block the attack by Chaos Rean, causing a powerful shockwave.

"How disappointing..." Chaos Rean said appeared so suddenly from behind which surprise everyone with an ?! over their heads except Mephiles and Xemnas.

Chaos Rean raise his arm and the channel chaos powers as it swirls with an ominous howl and fired a jet of darkness at Rean as he dodges.

"Okay that's it!" Levi got his Glaive out and then charge to help him but the barrier is so powerful enough it keeps preventing him.

"Come on, we gotta help him!" Shez yelled as the others agreed as they attack the barrier to help Rean but it proven futile.

"Ngh! What's with this barrier?!" Aqua growled.

"Zhongli!" Venti turn to him.

"I know!" Zhongli imbued power to his Spear and charge to pierce the barrier which a small crack appeared.

"W...What is he..." Mickey groaned.

"Nngh... How... is this... possible...?!" Emblem Vita groaned.

"W-Wait, how are YOU feeling pain?" Celine asked

"I don't know how... but..." Emblem Vita looking at Chaos Rean. "His power... somehow pierce through special properties... no... not just that... but defy reality!"

'No...' Zhongli grit his teeth, looking at Chaos Rean. 'Did he freeze time?! Who are you?!'

"All of you are nuisance and its time I rid of you all." Chaos Rean raised his hand and channeling a dark power as he dark chuckled. "Nyahahaha! Now PERISH!"

He was readied to launch his attack, causing Rean to look in horror as the vision of all his friends and lover pop into his head, causing him to grit his teeth.

"Nnnugh!" Chaos Rean winched as he place his hand to his mask. "You son of a—" Then his mask cracked. "?!"

(BGM ended)

"He did it!" Juna cheered as they saw the battle was over.

"That was impressive bladework." Laura smiled as the mask crumbled.

But when the mask fall out of Chaos Rean's face, his presence was revealed, a ominous presence that was enough to sent everyone's chill down their spine as they all had an ?! over their heads.

"Um... did anyone else feel that?" Teddie asked, feeling concerned.

"I think we all did..." Naoto Shirogane said. "As for what it was... it definitely felt something not of this world."

"Never mind that- look at his face!" Venti said as Chaos Rean's face was revealed.

(Legend of Zelda: Twilight Princess ost - Light and Darkness)

Chaos Rean got back on his feet, revealing his golden eye. His teeth grit, giving a glare. His hand hand was supporting his cheek.

"I knew it..." Fie muttered.

"Instructor...?" Juna gulped.

"What... is this presence...?" Tiki shivered.

"I don't know... but his presence... it's..." Aqua shuddered.

"Are you kidding me...?!" Chaos Rean gritted. "You're... even stronger than "him"?!" He growled, giving a murderous intention.

"Ngh..." Lucina flinched. "This... murderous aura...! It's too much!"

"Nnngh..." Chaos Rean growled but shook his head. "No..." He then glared at Rean. "You're only stronger because of that artifact."

Zhongli gasped immediately, knowing what he means.

"Artifact? What are you talking about?" Rean asked. "Wait, not just that. Who are you?" Rean asked. "Why do you exactly like me? What was that power during our fight? It's unlike anything I've seen before. And what is the goal behind the United World of Crossbell?"

Chaos Rean let out a sinister smirk. "Who indeed? I suppose this is our first meeting in this world. However..." He suddenly raises his Tachi and unleashes a dark slash of projections onto everyone, forcing them onto their knees, but as one strikes Levi, suddenly Zoa Balor grabs him and drag him across the room.

"Nngh!" Levi winched.

"I have no interest in talking." Chaos Rean smirked before he approached Levi. "Ahh... Levi Sullivan." He reaches out his hand to Levi's cheeks. "The man that Rean Schwarzer loves with all his heart." He hand traveled around Levi's face and then grabbed the chin. "Out of all the members of Class VII, it is you I wanted to kill the most. But I cannot... all because of this."

"Huh? What are you-" Levi suddenly was interrupted when Chaos Rean grasped his face and pulled him directly to his lips, forcing him into a kiss, with his left hand on Levi's waist and his right hand on my cheek. "Mm!?"

Everyone had an ! over their heads as many jaw drop and some look in horror. Rean was more horrified then turn to rage.

"Levi!" Juna exclaimed

"BASTAAARD!" Rean then charged at Chaos Rean with rage.

Levi unleash a dome of light to burn Chaos Rean.

"?!" He pull away as both their tongue and saliva drafted apart and Rean attacked with a downward slash, but he backflip as Venti shoot a stream of wind and knock Chaos Rean to the wall and slam him there. "Hmph!"

Zoa Balor dropped Levi and Rean caught him. Chaos Rean teleported to the terminal as he let out a sinister and evil laugh as he lick his lips with wet noise with a smug look on his face.

"Delicious." Chaos Rean smug. "Your power may have sting me, Levi, but I can see why that inferior fool enjoys kissing you. His love for you is so strong that raising his blade against the man he loves causes him to hesitate. Tch, what a pity that I had to inherit that from him. No matter how many times I want to kill you with my own hands, I could not thanks to that love for you."

"You son of a-!" Rean growled in rage while Levi was whipping his lips with his arms. "How dare you kiss my love... with your filthy mouth! I will make you regret that! But what this about inheriting feelings and planning to kill him?!" He yelled

"It should be obvious why, Rean Schwarzer. He's your biggest weakness in your heart. As for the feeling... who do you think I inherited?" Chaos Rean asked, giving Rean a narrow look before turning his back. "But enough about that. I already wasted my time. It's not exactly as planned... but the results will be the same. As much as I love to shove my sword to your chest, given you a thousand deaths, I'm afraid I'm very busy. So consider yourself lucky. But know this..." He glances to the team. "You cannot stop the inevitable."

Chaos Rean then raised his hand up high. "Heed my call... Zoa Gilstein, the Zeroth Knight!" He yelled and suddenly, Zoa Balor disappeared and then reappeared above Chaos Rean and emerged into the large silver Divine Knight which released an overwhelming aura that forced everyone to feel its mighty power.

"Nngh!" Leafa exclaimed

"What an overwhelming strength!" Lissa exclaimed

After the overwhelming power fades, Chaos Rean walks toward the Divine Knight and then look at everyone.

"Mephiles, Xemnas. We're leaving." Chaos Rean said.

"Understood." Xemnas bowed and he and Mephiles teleported by his side.

"Wait!" Zhognli yelled as he got back on his feet as he glare at CHoas Rean with his glowing eyes. "Who are you?! Your power... it resembles that of that power. How did you managed to obstain it? ANSWER ME!"

Chaos Rean glared. "Ah, yes. The one who damage Zoa Gilstein and my Aion Ridley. It's unthinkable that you managed to cause so much damage to my Divine Knight. I don't know who you are but. I will kill you... for ruining my moment!"

Levi gasped. "So... You're the one who was going to kill Rean!" His eyes glow white as he giving a death glare.

"Enjoy your time everyone. Because soon... each and every one of you will die by my hand... But before that..." He turns to Levi. "I'm going to discard these wretched feelings... and kill you first... my lovely Levi. Your blood will be one of the foundations of my victory. Hahaha... HAHAHAHAHA!" He let out a maniac laugh as he raised his hand to levitate into the air, opening a portal that caused him, Mephiles, Xemnas, and the Divine Knight to enter and then close.

"What... in the world is going on?" Lucina gulped.

"I don't know... but I felt more unexplained chills from his words..." Marth muttered as Rean collapsed into Levi's arms.

"Rean, you okay!?" Levi exclaimed

"Sorry, I'm fine." Rean replied as he pulled Levi into a kiss.

Levi responded in a surprise as the kiss was a little forceful, but he kissed back before both of their lips and tongue separated.

"There… that should rid of his taste." Rean said.

Levi sweatdrop. "That's your reason for kissing me?"

"But never mind that... I'm more concerned about what he said... and these unexplainable chills going down my spin."

"Rean..."

Rean grasp on Levi's jacket. "It must be a sign that the truth... is finally close at hand."

Levi nodded in agreement. "You're right..."

Venti headed to the terminal and from there he gasped. "Guys! Come quick!" He yelled as they gathered up to the terminal.

"Whoa... look at the size of this terminal..." Juna trailed off

"No, not that! Look!" Venti pointed and spotted the Sonorous Seashell.

"That's the Sonorous Seashell!" Rean gasped. "Someone called Professor Schmidt!"

(BGM ended)

Timeskip...

(Genshin Impact ost - Whisper of Irmensul or Sonic Frontier ost - The Last Piece)

"I've never expected to find something like this in the Castle of Mirrors. Let alone the disturbing setting." Matthew muttered as he arrived with Sara, Kurt, Ash and Schmidt as they found the Sonorous Seashell.

"I'm just glad everyone's all right. It sounds like you've been through a real ordeal." Sara replied

"It isn't just his strength that has me feeling uneasy. There was something... intrinsically ominous about our foe." Laura muttered.

"His powers is unlike anything we all have witness." Tiki muttered.

"It's like his powers comes from fear itself. Something that is beyond and within our understanding..." Marth muttered.

"Yeah. We might've underestimated what we're up against. Especially these guys who can bend time. And Organization XIII return." Fie muttered. "They're were our greatest enemies a year ago. Seeing them back causes enough chill down our spine after what we've went through in the Keyblade Graveyard."

"Yeah. Like that Heartless Core. It took everyone's efforts to kill that thing." Shez agreed.

"So this light is coming directly from the spirit veins?" Kurt asked.

"Yeah. Mr. Zhongli said the Castle of Mirror became a portal to an artificial dimension crafted by guy who look like Instructor Rean." Juna nodded.

"A dimension that somehow replica the Realm of Darkness, correct?" Musse asked.

"Yes. This adversary is someone we never must face alone." Aqua nodded.

"But damn. Who was that guy. It's like evil was his name." Lea wondered.

"I'm not so sure. But we can say that he hold power beyond our compensation." Naoto Shirogane said. "We'll add one of his abilities is manipulating time."

"Aww, just we need. Another bad guy with time manipulation..." Teddie groaned.

"But what about this device here?" Yukiko asked.

"Gyess all we know is that it's using the power form the spirit veins." Ash comment.

"Have you managed to learn anything more, Professor?" Altina asked

"Hmph. Don't ask like I'm some amateur." Schmidt replied. "Further analysis will be necessary, but it appears to function similarly to the projector that we found in Nord. However, its purpose is orders of magnitude more complex."

"Well, that doesn't sound good." Leafa muttered.

"You're telling me." Qrow sighed as he drink from his flask bottle.

"I'm feeling lost." Matthew admit.

"It's receiving significantly more power from the spirit veins than the device in Nord. What it is doing is on a much larger scale. Until we know exactly what that is, we must handle it with extreme caution." Schmidt advised.

"We can also add that this device is also responsible for jamming communications in this region by way of the Sonorous Seashell." Zhongli said.

"I thought so." Rean muttered

"But how did the artifact that Prince Olivert return to the church is here?" Venti asked.

"Perhaps we should ask someone from the church for further details." Mickey said. "Speaking off. I've also found Master Yen Sid's paintbrush here."

"The same one that the blot was being pull out from." Oswald added. "Which means our thief did came from this world... or rather... part of this "united nation" group."

"But why they would take the brush and leave it remains unclear..."

"That function, at least, I see no risk in disabling? Shall I?" Schmidt request

"Yes. Please do." Rean nodded "I'm convinced that all we did here was catch a glimpse at a mere fragment of the truth. We're not going to be able to handle this alone. We're going to need help."

"Very well. But our enemies will no doubt be able to detect that we have disabled it. Be aware of that fact." Schmidt said as he begin typing.

"It would seem there are still more shadows we have yet to encounter." Ryoma fold his arm.

"Agreed." Musse agreed. 'Why do I feel like I'm missing something?'

Schmidt deactivated the machine as it shut down. Then ringtones was heard as Altina, Amia and Sara pull out their ARCUS Alpha.

"An emergency call from the guild?!" Sara asked

"I'm getting one from an Intelligence Division secure line as well." Altina replied

"I'm getting one from my mother." Amia replied

Then everyone's ARCUS Alpha ringing.

"Whoa! My ARCUS just—" Juna pull out her as everyone did the same.

"The hell's going on?" Ash asked

(BGM ended)

"Thus do I call upon our good neighbors, Calvard and Erebonia, to make known their intent of joining our nation. They have until March 24 noon to comply."

(Trails into Reverie ost - A Nightmare to Revive)

"Rufus..." Iggy muttered.

"He's not..." Fie muttered

"What are the co-supreme leaders planning?" Musse wondered. "Is he hijacking orbal waves to broadcast this statement?!"

"Oh, that's just great." Lissa muttered.

"They're hijacking the satellite E. Gadd made? No... Or could it be possible they're capable of producing perfect replicas of artifacts..." Schmidt wondered

"Impossible. That technology was lost 1,200 years ago." Sara stated

"To you, perhaps. But don't forget that we are living in a new era of other worlds." Venti pointed out. "With now our technology has improve, it's possible we can analyzed them. I imagine our enemy managed to do that."

"What's more." Zhongli grabbed the Sonorus Seashell and notice a dark energy. "I sense an unknown power from it. It also appeared to be damaged too. It may be able to repair them."

"If... you think so... then..." Sara trailed off.

"What's more. We're dealing with an unknown force. Replicas of people... then reproductions of artifacts... and now beings who either defy or manipulate the laws of reality. Whoever this force is... this world will not know peace until we deal with the source."

'He's right. I feel like I'm finally starting to understand exactly what we're up against.' Rean thought. 'Which means our next play should be...' Rean pull his ARCUS Alpha and begin dialing. "I think it's going through." He said as someone answered. "Lloyd, do you read me?"

And that's the end of this chapter! Oh man, it was insane! It was also difficult of the fakes of the team to go in too. But I will add in the battle data for certain bosses.
