"This is so cool..." Sora muttered out loud at the Batcave. (Bonus: Base it off Arkham City's.)

While Sora was busy looking at it, Kairi was directly starting at Bruce, ready to ask him.

"So... this is your base as Batman?" she directly asked Bruce, who nodded in response to her.

Eventually, after some walking and scolding from Kairi to Sora, they made it to the Batcomputer, an oversized modern computer. Bruce eventually typed in the news and the headlines showed...

"Does other worlds indeed exist? GCPD reports two teenagers were found by Bruce Wayne and two medics, and reportedly Bruce Wayne took them in." the news anchor said. Sora and Kairi lightly sighed, and Bruce facepalmed a little.

"Guess we're popular, huh?" Sora said back to Kairi, who nodded. The news was still rolling. Maybe the two teenagers found peace. However...

Unknown Place

After being given a run-in by Joker, Riku was given a sword that apparently 'gets stronger if you use darkness.' It's name was Soul Eater for some reason.

'With this sword, maybe i can get away. But i need to touch my darkness, i guess. Just gonna give it time, and do what i am supposed to do.' Riku thought to himself leaning against the wall.

By then, the weird man appeared next to Riku. "You."

"What is it that you want?" Riku directly asked to him.

"If you want to use the darkness to enpower your sword, come train. Just follow me." the man explained what he wanted to do with Riku, who thought for a bit before nodding. "Alright. I'll do it." But left out the part he wants to leave when he's done, because surely the man and Joker would kill him.

Nearly three weeks later

The Wayne Manor

Sora had been spending the last few weeks training under Bruce's wing, learning new moves and getting acoustumated with the Keyblade. Kairi on the other hand, was taken in by Barbara Gordon, and learned pretty quickly. She was also remembering slowly her childhood secretly, not wanting to tell Sora and the others about it.

She had another one today, and a big one.

Flashback, ten years ago

Four year-old Kairi was gently picking up flowers when she saw a dandelion flower in one of the gardens. She eventually picked up, but then a weird creature appeared and tried to attack her. She screamed and ran away from it, while going after her.

"NO! RUN!" She heard a shout from a young woman who just arrived at the scene. Kairi eventually found herself near a wall and tried to protect herself from the oncomming strike, however the creature decided to not strike her, and she ran away to her, while more monsters appeared behind her, touching her hand into the woman's keyblade handle, in fright. The woman gasped a little, muttering. "This light...!"

"There's no way i can't fight like this..." the woman said, putting into a battle stance. When one of them was ready to attack the two, an giant anthomorphic mouse appeared, also holding a Keyblade, slashing the creature with one hit.

"Who are you?" the woman directly asked the animal. "Introductions later! Get that girl to safety, right now we need to stop those things!" the talking animal replied to the woman, who nodded and picked up Kairi and ran down to the stairs. When she was out of sight from the creatures, she instructed Kairi.

"Please, stay here until we're done with those creatures." she said to Kairi, who nodded. The woman ran back to the talking animal, who started to fight them. Kairi took a peek of the fight, and she saw precisive hits and magic spells. Once when the fight was done, she walked up to the two, who were chatting after the fight.

"Thank you. My name is Aqua, i train under Master Eraqus." Aqua said her name to the animal, who also replied. "And i'm Mickey! I used to be Yen Sid's apprentice. I came back to him for some more training." Mickey replied to Aqua, who nodded and changed the subject.

"I sense light within this girl. You think that's why they attacked her?" Aqua asked Mickey, since she saw a creature after Kairi. "Yep. I think ya may be absoutely right. If ya ask me, she must be someone pretty extordinary." Mickey replied back to her. Kairi smiled at that.

"Yes. I think she might someone who we're supposed to protect." Aqua said back to him. "Let's join forces!" Mickey said, holding his hand to her. However, something glowed from his pocket.

"Oh no, not now!" Mickey exclaimed, and a flash of light took over his body, leaving Kairi to gasp a little. "I'll be okay!" said Mickey, who was soon zapping out of the world. "See ya real soon!"

Kairi and Aqua was staring at the sky, where Mickey had left to, after the unprecedent. Eventually, she held out the flowers to Aqua. "Here."

"Are these for me?" Aqua asked to her, who nodded. "I picked you some flowers. Thanks for saving me." Kairi replied to her. She eventually picked the flowers.

"Oh they're lovely, you're so sweet." Aqua said to her.

"My name is Kairi, nice to meet you!" Kairi said her name to Aqua. "Nice to met you too. I'm Aqua."

"Kairi, about that light-" Aqua started to say, but Kairi's grandmother called her.

"Kairi!" Kairi's Grandmother called her name, gaining the two their attention. "Oh! Grandma!"

"Kairi, just a minute..." Aqua said to her, and then proceeded to touch her necklace. "I just cast a magic spell on you. One day when you're in trouble, the light within you, will lead you to the light of another. Someone to keep you safe." Aqua explained to her, who went from a confused face to a smiling one. "Thanks."

She ran back to her grandmother, while Aqua was looking at her. Kairi said her goodbye, and then she begged for her Grandmother to retell the story she always liked about. When looking at Kairi, Aqua quietly said. "Something tells me i didn't run into her by accident."

Flashback end

Kairi shot up from her bed, at 5:21AM. She sat on her bad, and grasped at her necklace. 'So... my necklace is how i got the Islands? I was guided by Sora's light?' she quietly thought to herself. She looked at the time. 'Great. God, i hate when dreams like that shoots me up early.' She thought again and yawned a bit.

"Maybe things were supposed to be." Kairi quietly mumbled while exiting the room.

Two hours later

Sora and Kairi were discussing about how the last two weeks came by.

"...And then i managed to learn a new move, where i toss my Keyblade like a boomerang, which can strike multiple enemies at once. I'd like to call it Strike Raid." Sora said to Kairi, who smiled at him. 'Maybe this is finally time i should tell him about it.' Kairi thought to herself, while smiling. She sighed a little.

"Sora, i think you should know the truth."

"The truth.. about what?"

Kairi sighed more, Sora was still the lazy bum she knew, even with all this training.

"I've been slowly regaining my memories of my childhood, before i arrived at the Islands. H-however..." Kairi stopped there, tearing.

"Kairi?" Sora asked her in worry.

"I-I think I d-don't have a home anymore..." Kairi couldn't hold it and started to cry, which prompted Sora to hug her, letting her cry on his shoulder. "It's alright... You're at least safe." Sora quietly whispered to her, while gently brushing her hair. The crying soon turned into a sob.

"T-thank you Sora." Kairi quietly said to Sora, still sobbing. "No worries, but now Gotham's our new home too."

"Anyway, i'm off to train again." Sora said, waving at Kairi, who questioned him. "This early?"

"Uh, yeah. I'm nearly done on my training so i'm pushing it 100% now!" Sora exclaimed while Kairi chuckled.

'He's still the lazy bum i know...'

Unknown Place, hours later

Riku had just recently finished his final training, now mastered a little bit of his darkness, which meant a stronger Soul Eater.

He was leaning against the wall when Joker approached him. "What do you want, now?"

"Oh-hohoho. Nothing, except that you need to come with me." Joker said, with joy. Riku thought about it for a while, but nodded. The two eventually walked to a room, with that man waiting. Riku didn't care about much, leaning against the wall, other than something called 'The Madhouse', which he didn't care until Joker snapped at him, causing the silverette to blink.

"Come, we have work to do."

Batcave

While Sora was training, Bruce was with his Batman suit, at the Batcomputer, researching about the Keyblade when he heard an urgent radio communication from the GCPD.

"All units, we need backup. Joker has invaded City Hall with those creatures. I repeat, Joker has invaded City Hall!"

Bruce upon hearing that immediatly put his hood on and went to the training grouds to call Sora, who was training at the time.

"Sora! Joker has invaded the City Hall! I need you to come with me!" Bruce called out to the brunette, who noticed him and nodded. "I'm coming!"

Sora immediatly put his hood up and ran to where Bruce was calling him to, and met Bruce at the Batcomputer.

"Remember; This is the real deal. You have to be careful and follow my steps, ok?" Bruce explained again to Sora, like he did when the brunette started his training. Sora nodded, then Kairi entered the Batcave, with something in her hand.

"Kairi? What's wrong?" Sora said, but she pulled down his hood, and put something in his right ear. "Huh?"

"That's a radio intercom. Me and Barbara desgined it. We're trying to sync it with Bruce's radio so you can hear it too. It might take a little bit so stay calm." Kairi explained to Sora, who nodded and pulled his hood back up.

"Got it. Let's go Batman."
