Traverse Town (Kingdom Hearts)

"Tell me what happened." Leon said when they got back to Traverse Town.

Everyone explained what happened at Hollow Bastion, from getting there, to losing their Keyblades, to getting their Keyblades back, to defeating Riku, to sacrificing themselves and waking up Kairi, to reviving, and then coming back.

"Holy crap..." Yuffie said in shock.

"So the darkness is flowing out of that Keyhole..." Leon said.

"No wonder there are more and more Heartless everywhere." Aerith said. "The only way to stop them is..."

"Seal the Keyhole, right?" Sabrina asked.

"Maybe, but no one knows what will happen once it's sealed." Leon replied.

"Well we can't just stay here! We have to do something! We have a friend back there!" Sora exclaimed.

"That's right." Leon nodded. "You have one more friend to worry about. Riku's Keyblade must have been born of the captive princesses' hearts just like the Keyhole you saw." He then looked at Kairi. "Of course, without Kairi's heart, it remained incomplete. Once that Keyblade was destroyed, the Princesses' heart should have been freed. Don't worry you two, if anyone can save your friend, it's you."

"Thanks." Sora said, and then Sabrina slapped him behind the head. "Ow! What was that for?!"

"I told you not to stab yourself, but what did you do? YOU FREAKING STABBED YOURSELF!" She yelled at him.

"Sabrina, he had to do it to save me." Kairi told her.

Sabrina sighed. "I know...but I just thought there'd be another way."

"Trust me, that'd be the last thing I'd do if I had a friend who lost their heart." Leon said.

"Hey, at least we're back." Sora smiled as they walked back to the second district.

Cid was busy working on something, just grumbling to himself. "Hey Cid." A voice said as he turned to see them.

"What's up?" Cid asked.

"We need to go back to Hollow Bastion." Sabrina said.

"I don't think I can let you guys do that. The Heartless there are multiplying by the minute. They'd eat your ship up." Cid told them.

"Well what can we do?" Sora asked.

"Simple. Go around 'em instead of through." He suggested. "Install a new navigation gummi and take a new route."

"A new gummi? From where?" Latias asked.

"The secret waterway. When I came here nine years ago, I stored it there in case I ever needed it. Never thought you kids would be the ones who would use it." Cid muttered.

"Thanks, see you later." Sora said as they all ran off.

Once they got to the Secret Waterway, Kairi was standing right there, just looking at the mural. "Kairi?" Goofy asked.

"Huh? Oh hey guys." Kairi waved. "I just thought I'd do a little exploring."

"With all the Heartless sneaking around? Girl, you're crazy." Sabrina said, not even noticing Sora walking to the mural.

Kairi giggled. "I guess it was my pure light that didn't make them come near me." She said.

"Who knows? We were fighting our way over here just to get the Navigation Gummi." Sabrina told her, and then noticed Sora walking up to them.

"I got it." Sora smiled. "Well, we should probably rest up considering we got tons of Heartless we have to fight just to seal a single Keyhole."

"Good point." Sabrina said.

"Well, see you all in the morning!" Donald exclaimed as they all walked away...though Sora and Kairi just stayed there.

Kairi (Kingdom Hearts II)

"A light at the end of the tunnel." Kairi said.

"Oh, your grandma's story, right?" Sora asked.

Kairi turned her head to him. "That's right. We were together."

"You know what's funny?" Sora asked. "We looked everywhere for you, but you were with us all along. Finally, we're together, Kairi." He smiled. "Now, it's time to get Riku back."

"You think it'll ever be the same between us? Riku lost his..." Kairi didn't want to finish her sentence.

"When we turned into a Heartless, you and Latias saved us, remember? We were lost in the darkness. We couldn't find our way. As we stumbled into the darkness together, We started forgetting things. Our friends, who we were, the darkness almost swallowed us. But then we heard two voices. They were yours and Latias' voice. You brought us back." He explained.

"We couldn't just forget about you. We just couldn't." Kairi told him.

Sora pounded his fists together. "That's it! Our hearts are connected and the light from our hearts broke through the darkness. We saw that light. I think that's what saved us. No matter how deep the darkness, a light shines within. I guess it's more than just a fairy tale."

Kairi smiled. "Well, let's go."

"You can't go."

Kairi was shocked to hear this. "Why not?"

"Because it's way too dangerous." He replied.

Kairi raised an eyebrow. "Come on, Sora. We made it this far by sticking together. You guys can't leave me here."

"Kairi, even if we're apart, we're not alone anymore, right?"

Kairi just looked at him. "I can't help?"

"You'd kinda be in our way."

Kairi sighed in defeat and giggled. "Okay, you win." She said and then gave Sora something. "Take this. It's my lucky charm, be sure to bring it back to me!"

"Don't worry, I will." Sora smiled.

"Promise?"

"Promise." Sora smiled.

Kairi smiled back. "Don't ever forget. Wherever you go, I'm always with you.

Unknown to the two of them, Sabrina, Latias, Donald and Goofy were eavesdropping. "Those two are so cheesy together." Sabrina giggled.

"And so darn cute." Goofy chuckled.

Later...

Traverse Town

All of them were in the same place, sleeping away when Cid opened the door. "WAKE UP, YOU GUYS! IT'S TIME TO LEAVE!" He yelled, as they all shot up awake.

"Ugh, how long did we sleep?" Sabrina wondered.

"Seven hours. All the sleep you ever need when there's Heartless crawling everywhere." Cid replied. "I put the gummi in your ship! Now move it!"

"Well, we all needed that rest." Sora said as he stretched and then they all waked to the gummi ship.

"Be careful, you guys." Kairi told them.

"We'll be fine." Sora gave her a thumbs up as the Gummi Ship flew off.

Cloudchasers (Kingdom Hearts II)

"You sure were cute last night." Sabrina smiled at him.

"What are you talking about?" Sora asked.

"You and Kairi...alone..." Sabrina gave him a playful wink.

Sora blushed in embarrassment. "YOU FOUR WERE EAVESDROPPING?!"

"Every single word, you cheesy boy." Sabrina giggled.

"It was just so cute, I'm surprised you guys didn't kiss." Donald smirked at him.

Sora just folded his arms in annoyance. "I hate you all..." He muttered.

Hollow Bastion (Kingdom Hearts)

Once they landed in Hollow Bastion, Marisa was still looking at the castle in confusion. "Where's Reimu?" Sabrina asked.

"Still in the castle with the other girls." Marisa replied. "They're in there for some random reason." She said.

"We'll go check on them." Sora said.

"You'll probably need my help." Marisa smiled.

Meanwhile...

Have a Nice Talk (Mario and Luigi: Bowser's Inside Story)

"Wait wait, repeat that. What did you say?" Peach asked.

"I said that I feel darkness close by." Lucy replied.

"It's the Keyhole that's pouring darkness, you're feeling that." Sailor Moon told her.

"No, no...it's not that. I'm feeling something else...like emptiness...more powerful than the Keyhole." Lucy told them.

Palutena folded her arms. "Hmm...you know, I did feel a strong presence after Ansem left."

"See what I mean?" Lucy asked.

"Now that you mention it...I thought I felt something when that Ansem guy left." Reimu muttered.

"Hey!" A voice called out to them as they turned to see Sabrina and the others walking up to them.

"Oh hey guys!" Lucy waved to them and then noticed something. "Wait a minute...you're members of Fairy Tail now?!"

"Yeah, before we left and told everyone we'd get you back, Mirajane gave us these." Sabrina smiled.

Lucy took a look at them. "Let's see... blue on your hand, light blue on Sora's leg, purple on Donald's hat, red on Latias' leg and white on Goofy's shield. How awesome!"

Marisa and Reimu just simply hugged. "I'm sorry I didn't come with you, there's something that was bothering us." Reimu said.

"The Keyhole, right?" Marisa asked.

"It's not just that, Lucy here keeps saying something about a strong empty feeling that's powerful than the darkness of the Keyhole itself." Rosa told them.

"I want to investigate it, but man...i'm just worried I might end up getting killed." Lucy sighed. "I know I have my celestial spirits with me, but what if this thing is more powerful than Loke or even Taurus? I don't want that to happen."

"We'll investigate it for you." Sabrina said.

"Heck, I'll investigate it with you guys." Reimu said.

"You will?" Sailor Moon asked in shock.

"Yeah, I mean, I got Spell Cards." Reimu smiled and then fist bumping Marisa.

"Well, you guys stay here." Sabrina said. "We got a Keyhole to lock."

"Alright." Peach nodded, while watching them walk away.

Hollow Bastion

"I wonder what this powerful thing is." Latias said.

"I dunno." Marisa shrugged. "But all I know for sure...if it's bothering the Princesses, we should put a stop to it."

"She's right." Sabrina nodded as they made their way to the huge Keyhole itself. "You guys ready?" She asked.

"Oh yeah." Sora nodded.

"Let's go." Sabrina said as they all walked inside the Keyhole...where a monstrous behemoth of a beast was waiting for them.

"What the CRAP is that?!" Marisa exclaimed.

"One mega Heartless, that's what it is." Sabrina said. "Let's take it out."

Destiny's Force (Kingdom Hearts)

The Behemoth slammed its foot on them, but they all dodged as Sora and Sabrina jumped up and slashed its horn.

Latias transformed and used Steel Wing, then using Psybeam on it as Donald used Thundaga and Goofy threw his shield.

"MAGIC SIGN: STARDUST REVERIE!" Marisa yelled.

Behemoth roared as it fired a laser from its horn, but they dodged as Sabrina used Strike Raid.

"TAKE THIS!" Sora yelled and used Ragnarock on the Behemoth, as it roared in pain.

"FIRE!" Donald yelled and used Firaga on it as Goofy jumped up and slammed his shield down on the horn and then got out of the way of Latias' Ice Beam.

The Behemoth fell down, weakly looking at them. "LOVE SIGN: MASTER SPARK!" Marisa yelled, as the laser hit Behemoth and then it roared until it disappeared in front of them.

"For a big guy, he sure got cocky." Marisa said.

Hollow Bastion

"Now, we just gotta seal with the Keyhole." Goofy said.

"Guys, you did it." A voice said as they turned to the source of the voice.

"Leon?" Sabrina asked as she and Sora walked outside.

"What are you guys doing here?" Sora asked.

"We came in Cid's ship." Yuffie replied.

"This is our childhood home." Aerith told him. "We wanted to see it again."

"It's in worse shape than I feared. It used to be so peaceful..." Leon sighed.

"Don't worry. If we defeat Ansem, then all will be restored, including your island." She said and looked behind them. "And Gensokyo and Alto Mare!"

"Booyah!" Marisa fist pumped while Latias just smiled.

"But, it also means goodbye." Yuffie muttered.

"Once the worlds are restored, they'll all be separate again." Aerith explained.

"Everyone will go back to where they came from." Yuffie said.

"Then we'll visit you guys with the Gummi Ship." Sabrina said.

"It's not that simple." Leon muttered.

"Before all this, you didn't know about the other worlds, right?" Yuffie asked.

"Because every world was isolated." Aerith said. "Impassable walls divided them."

"The Heartless destroyed these walls." Yuffie said. "But if the worlds return, so will the walls."

"Which means Gummi Ships will be useless." Leon told them.

"So you're saying we'll never...?" Sora asked, as Aerith and Yuffie sadly nodded.

"So I can't just visit these guys and their island whenever I want? That's lame." Marisa muttered.

"We may never meet again, but we'll never forget each other." Leon told them.

"No matter where we are, our hearts will bring us together again." Aerith said.

"Besides, I couldn't forget about you even if I wanted to." Yuffie gave them a playful smile.

"What's that supposed to mean?" Sabrina asked, giving her a look.

"GUYS!" Latias called out to them as they turned.

"Hurry! Come and close the Keyhole!" Goofy called out to them.

"Good luck, you guys." Leon told them as they nodded.

Sabrina aimed her Keyblade at the Keyhole and it fired a beam of light at it, immediately locking it. "That takes care of that." She said.

One regrouping later...

"I can feel it weakening." Sailor Moon smiled. "They locked it."

"Yeah, but now we have to deal with this strong emptiness." Lucy muttered as they then looked at them walking in.

"So, where's the problem?" Sora asked.

"It's at the place where you fought Maleficent." Peach explained.

"I can feel it getting stronger by the second." Lucy said.

"Come on, let's go." Sabrina said as they nodded and walked off, Reimu following them.

They walked in the room, looking around. "You sure it's this place? I don't see anything." Donald said.

Sabrina noticed something in the corner of her eye as she turned. "Uh, guys?" She said, pointing to a hooded figure walking towards them...and then it suddenly walked through Sora and Sabrina.

"What the heck?" Marisa asked. "That was weird."

"Way weird." Reimu nodded in agreement.

"Who the heck are you?" Sabrina asked.

The hooded figure stopped walking. "Ah, it seems you are special too." It said.

"Ansem?" Reimu asked.

The figure turned its head. "That name rings familiar." It said, and then suddenly, electricity formed in its hand. "You remind me of them."

"What's that supposed to mean? Who are you talking about?" Sabrina asked.

Sora noticed something and took out his Keyblade. "You might want to get out your Keyblade...and fast!" He exclaimed.

Sabrina nodded and when she did, the figure shot out a bolt of lightning at the both of them, as they both blocked it and then they slashed it away, as two lightning bolts hit the walls behind the figure.

"It means you are not whole." The figure said. "You are incomplete." It then chuckled. "Allow me...to test your strength."

"Bring it." Sabrina said as they got in a battle position.

L'Impeto Oscuro (Kingdom Hearts: Dream Drop Distance)

The hooded figure ran towards with two red blades out and slashed Sora and Sabrina, but they both dodged and then slashed it.

Latias transformed and used Psybeam, but it shot lightning at the Psybeam, as it created a huge explosion as the figure ran through the smoke and slashed Latias, but she flew up in the way in time.

"DIVINE SPIRT: FANTASY SEAL!" Reimu yelled.

"STAR SIGN: METEONIC SHOWER!" Marisa yelled.

Donald used Firaga and then Goofy bashed his shield on the figure's head, but the figure kicked Goofy away while getting hit by the Firaga.

"FIRE!" Sora yelled, but the figure formed a shield and then fired small shots at him.

Sabrina used Sonic Blade, but the figure jumped back before she could land a hit on it, and then it slashed her multiple times before kicking her away.

"TREASURE SIGN: YIN-YANG ORB!" Reimu yelled.

The figure formed another shield and then fired lasers at Reimu, but she quickly flew out of the way and fired simple danmaku at it. "LOVE STORM: STARLIGHT TYPHOON!" Marisa yelled.

Sora attempted to use Aerial Slam on it, but the figure stepped back and fired lightning at Sora, as it then pulled him up in the air. "HEY!" Sabrina yelled and used Zantetsuken on it, as it was blasted a few feet, then cartwheeled out of the way to dodge Latias' Ice Beam.

"DIVINE ARTS: OMNIDIRECTIONAL DRAGON-SLAYING CIRCLE!" Reimu yelled.

"CLOSURE SIGN: BIG CRUNCH!" Marisa yelled.

The figure attempted to dodge it, but Goofy rammed into it, which made the spells connect to the figure, as it yelled in pain.

Sora and Sabrina ran towards the figure and slashed it, but the figure jumped back and fired electricity at them, but they dodged as they both used Strike Raid, then Latias flew in and used Steel Wing on it, blasting it away as Reimu and Marisa nodded at each other.

"MAGICANNON: FINAL SPARK!"

"HOLY RELIC: YIN-YANG DEMON GOD ORB!" They both yelled at the same time as the unleashed it on the figure.

Once the spells hit and a huge explosion happened...the figure fell on one knee, but then it got up. "What?! How is that guy still standing?!" Marisa exclaimed.

"Impressive." The figure said. "This will be enjoyable."

"WHAT THE HECK ARE YOU TALKING ABOUT?!" Sabrina yelled as the siblings ran towards it as they both slashed, but Sabrina did her usual thing as she jumped up in the air.

Suddenly, the figure disappeared and then reappeared behind them once their Keyblades didn't connect to anything. "It is beyond your comprehension, for now." It said as they turned to it as it then turned to them. "Until we meet again."

"Who are you, really?" Sabrina asked.

It chuckled. "I am...but a mere shell." It said as it made a portal and walked in, then closing it.

Hollow Bastion

"I'm amazed it's still alive." Reimu said.

"No kidding, but what did it mean by it was a mere shell? I don't get it." Marisa said.

Sabrina sighed. "Well, I guess we'll be leaving." She said.

"Going to defeat Ansem?" Reimu asked.

"Yeah." Sora said and then sighed. "But I have this feeling we'll never see each other again." He said and then explained what Aerith, Yuffie and Leon told them.

Reimu sighed. "I was afraid of that."

"Hey, but cheer up! Remember what Leon told you guys." Marisa said as they nodded. "Besides, if you ever somehow manage to wind up in our world, we'll show you around."

"It's a deal." Sabrina said as they both fist bumped and then walked away.

"I guess I'll do some exploring of this place before we somehow teleport back home." Marisa said as she walked away.

"Right right, you'll probably steal some books from the library." Reimu giggled at this.

"Hey!" Marisa exclaimed. "I only do that in Patchy's library!"

"I'm just teasing." Reimu said, playfully punching Marisa's arm as they walked away together.

I wanted to add the Xemnas fight in it. :P

Meanwhile, a Paper Mario stage has been confirmed for the 3DS.
