I see many people were left intrigued with the little teaser I implied last chapter. Hahaha, well, time to address a few points:

1. Sora is born in the Destiny Islands in the Kingdom Hearts worldline. He is not from the DxD worldline. As you can see, it's his first time in Kuoh and he has no memories even if he was born in the DxD world.

2. Sora is the host of the Boosted Gear, in which Ddraig resides in. The Boosted Gear is one of the 13 Longinus of Highschool DxD, but characters keep on implying that it is one of the 6 that were lost and and nobody has ever found them. Somehow, Sora has it but how? He is from another universe.

Well, these are your clues. I told you there are mysteries that have yet to be solved, as expected from Kingdom Hearts. In fact, you can get more clues from the past chapters I've written and work your up from there. I hope you stay for the long ride, gentlemen.

(Play - "Tension Rising")

Ile and Nel were both shaking in fear, now aware of the danger that can be brought by this boy in front of them. Meanwhile, the keybearer kept his gaze towards the two chainsaw-wielding pawns before him, about to take off with his Flowmotion, when something abruptly stopped him from doing so.

"Impossible!" a voice said from behind Sora, causing him to turn around to see Mira recovering from being knocked down earlier. She also looked shocked, but was able to contain herself. "How can you be the Red Dragon Emperor?! The Boosted Gear is a lost Longinus, and hasn't been found by anyone yet!"

Sora frowned, being quickly reminded of his fight with Yozora and the things that he told him during that battle. "She's saying the same things that Yozora did… she's even calling me in the same way. I don't understand this at all… I'm not from this world… I don't have a Sacred Gear… do I?" He thought, looking down at his keyblade before another thing came into his mind. "And that voice… I heard it again… I know I've never met one, but it sure sounded something like… a dragon."

"It doesn't matter! Even if you really are the Red Dragon Emperor, we will defeat you for Riser-sama! I will win… and prove my worth!" Mira exclaimed, gripping her staff tight as she looked at her two fellow pawns. "Ile! Nel! Let's attack together and corner him!"

"Hai! Slice him up! Slice him up!" Both twins nodded as they raised their chainsaws and the three pawns began to charge towards Sora, who seemed to be too lost in thought to notice.

"Got you now!" Mira smirked as the three pawns looked like they were about to close the distance between them and Sora, only for the girls to widen their eyes completely when the keybearer disappeared by… transforming into a white orb? As soon as he was out of sight, Mira already began to fear the worst because this boy was apparently the host of a lost Longinus, leaving them clueless as to what he was capable of. "W-Where did he go…?!"

"Over here!" Sora's voice rang out, causing the three to quickly turn around, seeing that the boy merely teleported away to a short distance. Before they could do anything, he quickly used his Flowmotion to dash towards Mira, who wasn't able to defend herself in time as she got launched into the air with an aerial sweep. He quickly followed after her and delivered a volley of slashes imbued with the power of light, ending with a straight thrust towards the girl's chest, sending her crashing back into the ground at a great distance away.

"Mira!" Both blue-haired twins screamed in worry as Sora landed safely near her. Thinking that he was planning to do something to their comrade, this prompted Ile and Nel to look at each other and nod, before they ran towards the brunette with furious looks.

"I'm too weak to fight back… I don't stand a chance against him." The defeated Mira slowly looked up at Sora in fear, who was standing over her triumphantly. She closed her eyes when the boy crouched down and started to reach out to her with his free hand, only to feel him resting it on top of her head, causing her to look up at him again, but this time in complete surprise.

"Sorry about that, I hope I didn't hurt you too much." The boy grinned, giving her a headpat that made the bluenette blush slightly. "Don't worry about losing, because you did your best. I'm sure you'll be stronger in the future, Mira!"

The girl widened her eyes upon hearing his words, just as her body began to glow, signifying her defeat. "T-This boy… does he mean that?" Mira always thought that she was hopeless when it comes to being compared with her other peerage members and there was no way for her to improve.

Until this boy, who was apparently the Red Dragon Emperor, came along and told her that she could. Just from the smile on his face, it's like he was subconsciously telling her that everything will be okay, and Mira felt that she could trust him with this.

"Red Dragon Emperor… thank you." A smile managed to form on Mira's face as her whole body glowed brightly, before dissolving into the air through particles of light. Sora's smile faltered as she disappeared, before he stood upright and looked at his open palm with a somber expression.

"So this is what happens in a Rating Game," he thought. Somehow, he felt relieved that there would be no need for him to go too far when he's facing the enemy, and this was what he needed. "I guess I can work with this." Looks like this was still just a game in the end, which Sora preferred.

The boy snapped out of his thoughts just in time to see the chainsaw-wielding twins about to reach him, causing Sora to panic and quickly activate his barrier to block their attacks. While this was happening, Grayfia's voice spoke out through the intercom.

["One of Riser-sama's pawns has retired."]

"You'll pay! You'll pay!" Ile and Nel sang in unison, swinging their chainsaws wildly in an effort to break through Sora's light barrier, but none of their attacks were effective against it. A few seconds later, in the midst of their flurry of wild swings, the barrier exploded in a burst of light energy and sent the two young girls flying back.

"Thundaga!" Sora raised his keyblade and summoned down several lightning strikes that stunned the twins enough that they should be down after one more attack. He was about to take off with his Flowmotion, if it weren't for a new voice that stopped him in his tracks once again.

"Hold it right there, Red Dragon Emperor!"

Sora's eyebrow twitched in slight annoyance as he turned around, seeing a total of five different girls coming together in front of him. He raised an eyebrow at each of them, because they were all dressed in different outfits and it made him wonder what Evil Piece they represented. One of them only wore a bikini along with a few accessories that made the boy nearly want to turn away and blush, if only this wasn't a battle to begin with. Two of them were in French maid outfits, while the other two looked like they were catgirls who both donned revealing school uniforms.

"So this is the one who's supposed to be the Red Dragon Emperor? How shameful." The woman wearing a bikini spoke with her hands on her hips in arrogant fashion. She had long, pale blue hair with amber eyes that highlighted her tanned skin.

"He's pretty cute, so why don't we mess up that face of his a little bit?" One of the French maids said with a smirk. She had shoulder-length light brown hair and dark brown eyes. Her uniform was buttoned, sleeveless one with a white-laced design and she wore light gray tights underneath it.

"You made the wrong decision coming here alone, boy," the other maid boasted. She also had shoulder-length brown hair, although her uniform was a bit different as it exposed her cleavage. She also wore a pair of fingerless gloves that reached her forearm.

"I guess you're the rest of Riser's pawns." Sora smiled, deducing the identity of these girls before him. He then gestured to himself in proper greeting, "My name is Sora, and I'm Rias' pawn!" Upon hearing him introduce himself, the five girls laughed heartily in amusement before deciding to entertain him in the same way.

"Shuriya~"

"Marion!"

"Burent!"

The catgirls were the ones that followed, striking a cute pose. "Ni and Li! And we're all Riser-sama's pawns!"

Sora looked at each of them, before glancing for a quick moment behind him to see Ile and Nel struggling to recover after getting hit with his lightning spell. "Looks like he really did send all of his pawns after me, perfect… this is exactly what I needed." He thought, before gripping his keyblade tight and getting into his battle stance. The boy grinned at each of his opponents. "That's good, then! Let's do our best in this fight, everyone!"

His statement caused Shuriya to laugh arrogantly. "You plan on fighting all of us when you are alone? You're clearly outnumbered now, boy. You may be the Red Dragon Emperor, but you're just a—!" The woman was cut off when Sora dashed towards her with his Flowmotion, catching her by surprise and rendering her unable to defend against a keyblade slash towards her stomach that sent her skidding across the floor.

"So fast!" Marion exclaimed in shock.

Burent was also taken aback with Sora's speed, but she quickly snapped out of it as she looked at Ni and Li. "Quick! The two of you, trap him!"

Hearing those words, the two catgirls leaped towards Sora with the intent to hold him in place, but the boy caught sight of them and used an aerial sweep to intercept the two and caused them to fall back to the ground. Now in the air, he aimed the Oathkeeper towards the group of girls and prepared to fire one of his spells.

"Blizzaga!" A massive chunk of ice shot out from the boy's keyblade, causing the girls below to widen their eyes in panic.

"Dodge it!" Marion shouted, as the four pawns managed to avoid the spell in the nick of time. Their eyes widened at the huge glacier that got stuck on the floor afterwards, before looking up at Sora with serious looks. Now they were starting to understand that this boy wasn't someone to be trifled with.

While he was still airborne, Sora quickly noticed that Shuriya had recovered from his last attack and followed after him. "Take this, boy!" she yelled, cocking her fist back and it seemed like the woman was about to hit her target, if it weren't for Sora evading it with an Air Step and gaining some distance between them. "No! Get back here!"

Immediately after that, the keyblade wielder saw Ile and Nel were finally back up to their feet and were ready to charge into battle once again. However, he could tell that they were barely holding up and would go down after one more powerful attack. Sora dashed towards the two with Flowmotion, and they were too late to be able to react and do anything.

"Stop right there, boy!" Shuriya shouted, landing on the ground and chasing after Sora, who had already began his assault on the twins and there was seemingly no stopping him.

After a few light-imbued slashes that hit the two at the same time, Sora managed to disarm them of their chainsaws with a Radial Blast before he leaped into the air and slammed Oathkeeper into the ground, creating a shockwave that launched Ile and Nel into the air and both squealed in pain. From that attack, five pillars of light shot from the ground and went out in all directions. Two of them headed straight towards the twins and engulfed them in bright light, while the rest prevented Shuriya from getting to him as she evaded the pillars out of fear.

["Two of Riser-sama's pawns have retired."]

As soon as his attack was finished, Sora turned around and faced Shuriya, who was within distance as the woman looked ready to end him. "You're gonna pay for that!" she shouted, just as the boy raised his keyblade to block her attack. It became a battle of strength as the two tried to push each other back, until a voice rang out in Sora's ears.

"Now's our chance! Trap him while Shuriya has him under control!"

Sora quickly saw the remaining pawns charge towards him from all directions; the two catgirls from the left and right, Marion from above, while Burent was behind him. "They're all pretty good!" he thought with a small grin, before teleporting away with Sonic Dodge and caused Shuriya to nearly trip forward and the four other girls to stop in their tracks.

Shuriya quickly turned around when she felt a presence behind her, and she saw Sora standing there, ready to fight again. "You won't get another chance, Red Dragon Emperor! You may have gotten three of our comrades, but this ends here!" she said as Riser's pawns all stood side by side before the keybearer.

Sora shook his head with an apologetic expression, standing upright and outstretching his free arm as though he was going to explain something.

"Sorry, but I don't plan on losing this fight. I'm going to win this for Rias, and I still have to send a message to your master about underestimating us!" The boy then looked at his hand and closed it tight, before he looked up at his opponents. "Don't take this personally, all of you!" He twirled his keyblade with a grin on his face, before his body became covered in light.

"No!" Marion shouted, knowing what this meant after seeing the young brunette fight against Mira, Ile, and Nel earlier. The other girls with her just stood there as well, unable to do anything about this.

[BOOST! BOOST! BOOST! BOOST! BOOST! BOOST! BOOST! BOOST! BOOST! BOOST! BOOST! BOOST!]

"Haagghhh!" Once the light was gone, Sora had transformed into his Double Form, now holding the Oblivion keyblade in his left hand as well. "Let's do this!" he exclaimed as he twirled both weapons in his grasp.

"He has… two of them…" Burent whispered, being filled with fright. One of them was bad enough, and that was because it could use light [which was fatal to them] but what about a second? Just from the look on that dark-looking keyblade, it was imbued with the power of darkness, and that wasn't a good thing at all.

"We're…"

"Screwed." The catgirls said nervously, gulping heavily as the two had major doubts on whether they could handle the boy or not.

"Hey Roxas, those are your keyblades." Xion pointed out as they watched Sora summon the Oblivion keyblade in his left hand and go into one of his transformations. "I guess Sora can still use those even in a different world."

"Yep," the spiky blonde nodded. As soon as he saw his other use Oathkeeper, Roxas had a good feeling that Sora was also able to utilize Oblivion. "I guess he wants to end this early, and save up energy for the remaining ones. Those girls have no chance against Sora now, it's better if they just surrender."

"This is the power of the Red Dragon Emperor…"

"Is it really Ishida-senpai, though? It's hard to believe that someone from another universe has one of the lost Longinus…"

"Trust me, everyone else is as confused right now… this doesn't make sense at all."

Roxas turned towards Momo, Ruruko, and Reya, whom he heard whispering about something just nearby. "What are you three talking about over there?" he asked, raising an eyebrow.

"The two of you," Sona called out and getting both friends' attention. She looked really serious and was in need of urgent answers. "I need to ask you something. Since your hearts were once a part of Ishida-kun in the past, did you ever see something else residing inside of him? Something quite akin to a monster?"

While Xion was left conflicted on what to answer, Roxas shrugged his shoulders. "I have no idea. As far as I know, there's only one other heart besides us that lived inside Sora back then. Are you talking about the darkness inside his heart? There's no need to worry about that, he's got it under control."

Xion widened her eyes, realizing what the Sitri girl was likely referring to. If she was talking about a monster, then only one thing fits that description. "Sona-kaichou, does this have something to do with that voice we keep on hearing just now? Are you saying that there's something inside Sora which has that voice?" she asked, frowning in confusion.

Sona only nodded.

"What…?" Roxas narrowed his eyes, noticing that there was something weird going on. Those were Xion's exact words towards him earlier, and she just repeated it for Sona. He didn't think too much of it since he thought that voice yelling 'Boost' was something/someone from the enemy's side. "Hold up, are you telling me that there's something else inside Sora besides the three hearts that he kept safe?"

"Roxas-san, Xion-san, I'm afraid that there's something important you need to know about Ishida-kun…" Sona began, glancing at the monitor for a moment.

Shuriya had the same reaction as her fellow pawns, before she managed to snap out of it and fought back the fear building up inside of her. "Don't falter! Remember that we are supposed to win this for Riser-sama! Don't let your fears take over!" she shouted out, looking at Ni, Li, Marion, and Burent. "Even if this boy is the Red Dragon Emperor, he is not invincible! He can fall in battle!"

It took a few moments, but Marion was the first one to respond, shaking her head to recompose herself. "R-Right! We can't lose faith! We'll win this for Riser-sama!"

Her words prompted Burent to do the same, shaking off the fear she felt and scowling at the keyblade wielder. Ni and Li raised their fists and flashed a determined smile, a burst of motivation flowing in them. There were still five of them, while Sora was all on his own. Even if he now had two keyblades, it wouldn't matter if he didn't know how to defend himself.

"Promotion: Queen!" all females shouted at the same time as a bright orange aura coated their bodies for a few moments before it disappeared, a clear sign of their promotion. As soon as they felt the added power to their abilities, they felt more confident that they can bring down the lone pawn standing in front if them.

"Gotta be careful and have to keep an eye out on all sides," Sora thought as he witnessed Riser's servants promote themselves into the most powerful piece. He glanced at the Oathkeeper and Oblivion for a moment. "I'm sure using both these keyblades should be enough to take care of them, so I'll save promoting for later."

"Attack him all at once! He can't defend himself against multiple people!" Shuriya shouted as she charge towards the keybearer, remembering how Sora had to teleport away in order to prevent himself from getting cornered earlier.

The two catgirls began to circle around the boy, aiming to attack him from behind. Marion and Burent ran towards his left and right side, and with their added attributes, it only took them a few seconds to completely surround Sora with nowhere else to go. The keyblade wielder didn't even move from his place, knowing that he'll be caught either way.

"We've got you now!" Shuriya smirked in triumph, only for her eyes to widen when Sora had raised his keyblades to finally retaliate. "Damn it!"

It happened in a span of a few seconds. Riser's pawns were all blown away with the range of Sora's slashes while Shuriya was the boy's main target. He swung his keyblades in many directions and each attack was a direct hit towards the woman due to his wide reach. Even with the Queen's high defense, it wasn't enough to protect the blue-haired pawn from the raw power brought by Sora's Double Form.

"Take this!" Sora slammed his keyblades to the ground, summoning several pillars of light and darkness that sent Shuriya into the pair. He was about to finish it off, only to be forced to teleport away in an orb of light and dark when he felt two of his enemies were right behind him.

As soon as he disappeared, Marion groaned in frustration while Burent went towards Shuriya to check on her condition. The bikini-wearing woman was still conscious, but it was clear that she wouldn't last long. "Shit! We almost had him there!"

When Sora reappeared a few seconds later, he immediately found himself in the middle of Ni and Li. "Uh oh." Even the catgirls had been caught off guard that he showed up out of nowhere, but they were able to react in time to rear their arms back to punch the keybearer at the same time. Sora quickly blocked their attempted attacks with his keyblades, but that was when he saw Marion heading towards him at full speed.

"Hold him there! I got him now!"

Sora narrowed his eyes and used his Flowmotion to rush towards Marion almost instantly, which also got himself out of trouble before it could happen. The brown-haired maid was quickly filled with fear as Sora flew towards her like it was nothing, leaving her vulnerable for the keyblade wielder to strike her abdomen, sending her flying back and crashing into Burent in the process.

"Get back here!"

"We'll make you pay!"

Sora quickly turned around to see Ni and Li leaping towards him like a pair of cats, before he intercepted their attack with a flurry of slashes as he jumped into the air. They screamed in pain as Sora swung his weapons similar to a tornado before he thrusted his chest out, releasing some of his own light that seemingly burned the two girls alive. "Back off!" He spun in the air and swung the Oathkeeper keyblade at Ni while delivering a strong kick towards Li, sending them to the ground with their fellow pawns, nearly defeated.

"H-He's too strong…" Burent was the only one who could still stand among her comrades, although she had sustained injuries of her own. Looking around her, she saw everyone else barely able to move while Sora was running towards them while gripping both of his keyblades tight. Despite the innocent grin on his face, he looked determined to win, even if it meant not stopping anytime soon.

Burent was tempted to just run away in order to avoid whatever attack the boy was going to pull off, but that would mean leaving everyone else behind. Even if she did escape, she wasn't sure that she would be of much help to the match anymore, and that was assuming if the Red Dragon Emperor didn't chase her down personally

Hey, at the very least, she had faith that her Riser-sama would bring Sora defeat, because her master always wins.

And so, the French maid chose to fall to her knees, looking at Sora who raised his keyblades into the air, creating two large magic circles above and below all of them as the brunette jumped into the air and performed a backflip before pushing his chest out.

"Light!" Sora yelled as the magic circles produced massive pillars of light that engulfed all of Riser's pawns, who were directly within it.

"Such power… from a lost Longinus… we underestimated him…" Burent whispered, closing her eyes as she gracefully accepted her defeat at the hands of Rias Gremory's pawn.

(Stop playing - "Tension Rising")

["Five of Riser-sama's pawns have retired."]

After the big revelation of Sora being the host of a lost Longinus dropping into the clubroom like an atomic bomb, Rias and her peerage surprisingly didn't stay shocked for very long as they continued to pay complete attention to the ongoing match. After all, they were indeed in a Rating Game and they couldn't afford any distractions.

Still, they were in complete disbelief upon finding out that their friend, who hailed from another dimension, was in fact the host of a lost Longinus of this world. He was the Red Dragon Emperor, an alias given to the host of the Boosted Gear, one of the six lost Longinus that have been missing since the creation of them by God. Rias had her suspicions about Sora on this matter from the day they met, but she thought of them as nothing serious because her servant wasn't even from this world.

She couldn't believe that all of it was actually true.

As soon as Grayfia's voice was heard over the speakers, Kiba spoke up since he knew what this meant. "He did it… that's the last of them. Sora defeated all of the Phenex's pawns."

The blonde Knight was about to stand up and leave, but Rias quickly stopped him. "Wait, Yuuto! Let's wait for Sora to tell us himself," she said with a serious look. "He has the communicator, let's wait for him to give us his report."

As soon as she spoke these words, Sora's voice rang out in the clubroom through the device that Rias gave to him. Everyone paid attention to the spiky brunette's voice, knowing how crucial he was to the overall plan.

"I've taken care of Riser's pawns, everyone. There's no one else here in the gym, so I'm going to try and see if there's someone waiting for us up ahead. Don't worry, I'm staying out of sight. I'll meet you guys halfway."

Rias turned towards the members of her peerage the moment Sora's message ended, as she stood up from her seat with a deep frown on her face.

"I know all of you have many questions in your heads right, now… because I feel the same." The girl said, clenching her fists as she knew of the one thing that lingered in everyone's mind at this moment. "Yes, Sora is apparently the host of the Boosted Gear, a lost Longinus of our world, but we cannot let ourselves get distracted! The questions can come later, because right now, we are still in a Rating Game against another peerage!"

The looks on everyone's faces turned serious as well, while also nodding in agreement to Rias' words.

"Instead of being taken aback by all of this, let's use this to our advantage! With a Longinus wielder on our side, we have a good chance of achieving victory! You've all seen Sora fight, and you know how strong he is. As long as we do the same and fight with him, we can win this!" Rias exclaimed, raising her fist in the air.

"Hai, Buchou!" All of her servants nodded, each donning smiles on their faces as they too realized that they have a high chance of winning this whole game with Sora on their side.

Rias grinned before throwing out her right arm towards the door. "Now let's go out there and fight alongside Sora!"

"HAI!"

And there we go. I promised we'll get some action and we got it. Riser's pawns were all dominated and stood no chance against Sora in his Light Form/Double Form, even though they promoted to Queen in the end. That's the problem of facing someone with all 8 pawns inside them.

Hmm, if Sora is the host of the Boosted Gear, then Roxas and Xion should've come across Ddraig since they were all inside of him at one point, hence Sona asked them. Unfortunately, the two didn't know anything. I wonder where this leads. Next chapter should be interesting, because we're gonna get more action from the Rating Game.

Goodbye… and good night! BANG! *too sweet gesture*
