Warnings: Yaoi (which means men loving men), cursing, possible lemon/lime in future, and very confuzzled authors.

Pairings: eventual Sora/Riku, Soubi/Ritsuka (yes! It's a Loveless crossover!)

Summary: Begins at end of KH2. Sora and Riku are called away on a mission given by the King! And the world that has to be saved is one where cat ears and magic are normal. Interesting… Is Sora's change in age really necessary? KH/Loveless Xover

Prologue:

Sora took the bottle from Kairi's outstretched hand, quickly pulling open the seal. Faintly, the brunette boy could feel Riku begin to read it over his shoulder. Azure colored eyes darted across the page, drinking up every bit of information he could get. He heard Riku gasp in his ear, and Sora almost frowned; knowing the older boy read faster than him. Not to mention it felt weird to hear his shocked gasps. It was much different from when he was in pain.

Sora felt his eyebrows knit in confusion and began rereading from the beginning, ignoring as the redheaded girl Kairi slowly made her way to look over his shoulder as well. Sora handed the letter over to her, glancing at the boy behind him. Aqua eyes hidden behind silver bangs slightly tinted red by the powerful sunset at their shoulders met his gaze.

Licking his chapped lips, Sora finally spoke, ignoring the small fit Kairi had decided to throw. "Think we can do it Riku?" The aqua-eyed boy shrugged, turning his gaze to the falling orb in the sky. Sora turned completely, grasping Riku's shirt. "The King thinks we can."

Riku turned back to Sora, and the brunette could see the worry in his eyes. "But changing your age?" A small smirk, it looked kind of forced, made its way across Riku's delicate lips. "You just grew up and he wants to make you even younger than before?" Sora pouted faintly, his naturally pink lips pushing out slightly in retort.

Kairi finally decided to speak up. "But the King thinks it is necessary. The world hasn't been locked yet."

Sora peeked over his shoulder at her. "I don't know why you're up for this; you don't get to go Kairi." The girl deflated somewhat, but Sora didn't apologize. What was the point, the King specifically said she couldn't go, that "The Princess of Heart would only get in the way". Harsh, but most likely true. King Mickey knew what he was doing.

"When did he say we were getting picked up?" Riku sighed, his eyes seeming to glow in the slowly coming darkness. Kairi shrugged and Riku began to walk down the wooden bridge. "Might as well pack now. Who knows when he'll show up then?"

Sora scowled, a little miffed having missed the most spectacular sunset since Twilight Town. "You mean you pack… None of my clothes are gonna fit!" Kairi and Sora heard Riku's chuckle. "Riku!" Sora practically whined, running after the older boy. "It's not funny!"

No more comments were made as Riku untied his boat, glancing up at the pouting brunette and the giggling redhead. With a questioning look, the two joined him, the three all barely fitting into a boat made for a fourteen year old. As Sora and Riku rowed back to land, Kairi read over the paper. "What's this about ears?"

"Cat ears," Riku answered, tearing his aqua gaze from the sky back to the duo in front of him. "I heard from DiZ once about some worlds having genetic mutations, and to fit in, one had to replicate those. Sometimes bodies would automatically adapt, other times it has to be scientifically done." Kairi giggled, and Riku continued. "From what I got from the letter, the cat ears are a symbol of childhood, of innocence in that world."

"So…" Sora paused in his rowing; they were maybe a few feet from the dock. "You and I are gonna grow ears?" Riku shrugged and Sora lowered his gaze to the boat. He was amazed at how much Riku learned about different worlds while he was asleep, Namine chaining all his memories back in place. "A symbol of innocence…"

Riku couldn't help but chuckle. "Think of it as a visual way of telling who is a virgin, and who isn't."

Sora flushed the color of a cherry, Kairi right behind him. "Riku!"

"What?" The silver haired boy continued to chuckle, climbing out of the boat to tie it up. "It is true."

Sora practically slumped in the boat. Each world was completely confusing and different. Customs, beliefs, even physical appearances. And Sora even was going to be returned to the age of twelve! Why? Because that world needed him to be twelve. It was necessary. As were the ears… And holy snap! He'd have to begin puberty ALL OVER AGAIN! That was going to be hell, much less the very embarrassing mornings where he'd wake up with a problem (not saying he didn't do that now, but it'd be much more frequent). Sora groaned, ignoring the worried looks Kairi shot at him.

Twelve year old Sora, in his thin, petite like form practically glared at seventeen year old Riku. Even though his mindset was still that of a sixteen year old, Sora resisted the urge to cling to Riku. Riku was in charge of protecting him now. Even though Sora remained the Keyblade Master, Riku was going to be what Mickey called the Fighter, whatever that meant.

The Mouse King smiled faintly at the two boys, the ones who had already risked their lives for the worlds twice, and were about to do it again. Sora didn't look too pleased with it, but Mickey knew Sora would eventually be won over. He figured it might be something with the cat ears he was about to receive once stepping foot on the planet. "Now," the King spoke up, catching the chuckling seventeen year old and the pouting twelve year old's attention, "Once you land on that world, you're bound to the rules and restrictions of that world, just like before. Luckily there haven't been any reports of Heartless or Nobodies, so your Keyblades shouldn't be necessary.

"However, they have fighter units. Riku is the Fighter in the duo, and his job is to completely obey Sora." Sora perked up at this, sticking his tongue out at the former. "However, in battle Riku is not the one to receive damage, which would be Sora. Your position is called the Sacrifice. And to deal damage, one uses spells, harmful phrases to trap or cause harm to the opponent's Sacrifice." Sora and Riku nodded, faintly confused why they weren't opposite. Riku's tolerance for pain was greatly higher than Sora's, and the brunette had an easier time following Riku's orders. But the King apparently knew what he was doing.

The King guided them over to the gummy ship's door, opening it with the press of a button. "The one disadvantage is that you will be unable to contact me. However, I do have Merlin watching this world with a close eye, and once the keyhole has been sealed, I will return to this exact place to pick you both up."

Sora nodded, grinning his stupid smile. "Okay, then I guess this is goodbye, Your Majesty?" Mickey nodded. Stepping closer to the opening, Sora bit his lip. This was kind of nerve racking… exploring a world without Donald's magic or Goofy's protection to help him. He felt a much larger, calloused hand take his own, and azure eyes peered up into aqua. Riku gave a small smile, as if asking, 'ready to go?' Sora nodded again, he didn't need Donald or Goofy or the King or Merlin or anyone else. He had Riku with him.

And the two stepped out.

Hitting the ground, Riku immediately felt additional appendages on his body. Two cat ears twitched on his head, Riku wincing at how many more sounds he could hear, his silver Persian tail tensing in apprehension. Glancing around, he spotted the petite brunette at his side, calico-like ears (colored his regular brown and bits of Roxas's blonde) twisting which way and that, Sora's matching tail swishing side to side pleased. The now twelve year old practically jumped up and down, "Wow Riku, you have ears!"

Riku glanced away, holding in his chuckle, "You do too, Sora." Sora glanced over his shoulder, trying to see his over active tail. Riku eventually broke out into full laughter as Sora spun around himself, chasing his tail. Arms much stronger than Sora's now reached around the boy, pulling him close into a hug and stopping the chase temporarily. Sora only reached to Riku's stomach, chest if one included his ears and hair, and the silver haired boy felt Sora tilt his head in confusion. Was it another attribute of this world that they would act like cats too? Hesitantly, Sora returned the hug, before giggling.

"Know what Riku?"

"What?" Aqua eyes peered down at the gently spiky brown hair and ears, trying to keep his amusement off his face. Sora was just too cute.

"I think I like it here."

Riku's grin widened. "I think I do too."
