Little something I had in mind a while ago. From chapter 159 without the zombie-attack and with slight changes. Dunno if it's any good, but maybe it'll get better ? : 3

………………………………………………………………………………………………………………………………………………………………

Lavi picked up a box full of who-knows-what from the floor. 'The science department makes some crazy shit, better not to fall down or something' , he thought. He didn't even want to know what he was carrying or what would happen if he fell.

The sun was going down outside of the black order, which was on the move because of the attack the other day. Lulubell had apparently caused too much damage and they had the plan to use the arc to move the HQ somewhere else. And all of them were assigned to help, so our favorite exorcist were taking the science-teams stuff away.

As he walked with the box he accidentally bumped on to one of the many shelves and there was a loud thump and a yelp at the other side.

"Yuu-chan? You okay there?" Lavi peeked over one of the long stack of books and papers to see what had happened. There was no one to see. Lavi frowned and put the box down to investigate further. He walked around the shelves and found a bundle of clothes.

"Eh? What's this?" Lavi stalked curiously closer and noticed some long black strands of hair coming out of the seemingly like a shirt. And now that he was looking he had to admit that it didn't look like just a pile of clothes, There was something in. 'wait… Those clothes look familiar'

"Yuu…?" Lavi had a dubious look on his face because he had the hardest time to believe it was Kanda. Why were the clothes like that- like kanda had suddenly shrug or something.

"Ite-- Why the hell do they put those fucking boxes on the top of the shelf?! Are they trying to kill us with traps like that?" Kanda finally rose to sit and rubbed his head looking as irritated as ever. In addition being as little as a 1. Grade kid. Lavi stared at him with a blank expression.

"…What are you looking at?" He tilted his head scowling and Lavi couldn't help but think that Kanda looked a little cute like that. "Lavi?"

He shook his head a little and couldn't help but smirk subconsciously just by imagining Kandas reaction. 'This is gonna be fun.'

"Well you see… Why don't'cha try standing up?" Lavi suggested smiling sunnily.

"What's up with that, stupid? I- "He got cut off as he almost tripped on his pants that were practically a huge slump on his legs. "What the fuck?!" Kanda stared furiously at his clothes and lifted an arm overwhelmed by a shirt to look at it. Lavi was trying to suppress his snickering but failing miserably when Kanda lifted his head to look at him with this partly irritated and disturbed expression. Lavi couldn't help himself and just cracked at Kanda, who didn't look one bit amused(he never does, does he?). "You're so cute, Yuu-chan!" Lavi gasped between laughter. Mugen was quickly unsheathed and pointed at Lavis throat, a bit wobbly thou because the sword was much heavier for a elementary kid.

"I. Am. Not. Cute." His voice was all ice. "And stop calling me with my first name, usagi!"

"Aww, come on Yu-"

"I'm going to cut you."

"… Maybe we should find Komui or Reever then?" The redhead quickly finished and backed away a little. Even though Kanda probably couldn't use Mugen as effectively as in his original state it was certain when angered Kanda could hurt you with anything. Especially if the anything was a sharp katana.

"Che." Lavi assumed it was a yes and turned around. Kanda tried to follow but almost tripped again and stopped to tighten his belt. Then he rolled his pant so he could walk somehow, but it just didn't work properly. Lavi was leaning on the door and smiling at little-Kandas effort. Finally he gave up and glanced at the door where Lavi was beaming.

"What are you looking, baka usagi?! Why don't you go find Komui before I'm really going to kill you?" He threatened.

"Woah, no need to get so heated up. I didn't say anything…" The redhead waved his hands defensively.

"It's not just the idiotic things you say. Go."

Lavi sighted. " you're no fun." But quickly did as he was told. Kanda followed as fast as he could.

A little later:

"Ah! Komui!" Lavi waved at the toupee- wearing man at the centre of random group of scientists. He rushed to the man's side. "I need you for a bit."

"Oh, Lavi. How's the packing going? No problems?"

"Well… Now that you're mentioning it, we do have a little problem on our hands." Komui looked at Lavi questioning as he stepped aside revealing the struggling Kanda trying to get to where they were about 10 feet away.

"I see what you mean." Komui said slowly when Kanda finally got there.

"Komui, you bastard!! You better know how to turn me back really fast!"

"Well, it really is Kanda-kun, the way he speaks." He leaned closer to look at the little man better. "What happened?"

"I was about to get those fucking boxes on the science department and something dropped on me. Then I was like this, so-"

"Actually I think it might have been my fault. I bumped into a shelve and I guess Yu was on the other side…"

"Hmm… I guess you're about seven years old."

"Just cure me, so I can kick that rabbits ass!"

"I can't. And it doesn't need me, it should wear of about… ten days or so"

Silence.

"You've got to be fucking with me. Ten days!?"

"Yes. If I remember right, you age a year every day. You'll be eight tomorrow and nine after that and so on. When you get to your original age it should stop. I Didn't remember we still had that."

"And you guys invent these types of things…Why? Don't you have any real jobs to do?" Lavi retorted at the side incredulously. He could sympathize with Kanda.

Komui just stared at him trough his glasses for a moment. Suddenly there was his favorite bunny-cup on his lips and he just turned and said: "Lavi, I put you on charge of Kanda until he's back to normal. He can't go to any missions and apparently it was your fault so you take care of him. I think I hear Reever calling me. What is it Reever? Oh, you want me there?!" Lavi just watched as he walked inhumanly quickly away pondering, were they really ok with him on the lead.

'Wait. I'm in charge of Yu?' Lavi turned suddenly towards Kanda. He was gone.

"Ah! Yuu!" Lavi yelled after the further moving back of a seemingly seven-year old. He caught up quite fast and started to walk beside him. He tilted his head to see the other ones face. "Where're you going?"

"My room. I don't need a babysitter. Especially not you!" Kanda growled and didn't even look his way, just kept going." Komui must be out of his mind."

Lavi pouted. "What do you mean by 'especially not me'? You'll hurt my feelings. You don't even know how good I could be." He smiled mischievously, there was this little twinkle in his eye.

"I really don't give a fuck" Kanda tried to shake off the annoying redhead, but noticed that it isn't so easy when your feet were half of the ones you used to have. And at that Lavi wasn't a sappy little kid like he was. 'At least not on the outside' Kanda thought. And he started to get more and more annoyed because he couldn't get away from Lavi. 'God damn! These clothes are a drag' He stopped to pull his pants up, but didn't have the change to finish it properly when suddenly Lavi lifted him up.

"Eh-" Before realizing what had happened he was safely lying on the redheads shoulder.

"Wha-What do you think you're doing!?" Kanda blushed furiously and kicked the man in his stomach.

"Ouch! Settle down. I'm taking you to my place of course." He smiled confronting.

Kanda was totally dumbfounded by the situation. "your place…" He glanced back with a little shocked face. Lavi was surprised how Kanda had calmed down so suddenly, but it just encouraged him to tease the 'kid' more.

"Oi, Yuu-chan~, I wonder what you're thinking ." He teased. "Just to refresh your memory, you're still a seven-year old. And you know, no matter what your image on me might be, I don't do minors." At the end of the sentence Kanda was blushing again from embarrassment and Lavi was laughing hard.

"Baka usagi, let me go or else..." He left it hanging in the air, trying to get the redhead scared of the consequences. But it didn't quite work when he was lying on the other ones shoulder, incapable of reaching mugen.
"Aww, come on! It'll be fun!"

"You've got to be kidding me."

"Don't be so cold. We're here!" Lavi opened his door and stepped inside. He put Kanda on his bed and turned back to the door. "Should I put a lock here?" He joked.

"Like that's going to stop me."

"Well, if you reach it." Lavi smiled teasingly.

"...I'm not that small." Kanda frowned. Weirdly he didn't seem as reluctant as earlier. Lavi wondered about that with his arms grossed on his chest leaning on the door.

"You're going to stand there the whole night?" Kanda scoffed.

"Maybe." Lavi was thinking and watched him unusually calm. Kanda eyed him suspiciously.

"Nah, I'm kidding." He smirked and jumped next to Kanda. "We can sleep side by side."He grapped mugen quickly from Kanda."I'll keep a hold of this for a while." The redhead put it up on his closet. Too high for Kandas little arms.

"Don't touch Mugen! It's not up to you if I use it or not."

Lavi went under the cover and soon Kanda found himself being covered by the blanked too.

"Hey! I don't feel like sleeping." He said kind of childishly.

"Come on, Yuu~. Little kids must go to sleep early."

"You're the only kid here."

"Sleee~p. Or I'll sing a lullaby for ya. And for the record, I sleep one eye open so you better not try to get away."

"Don't you have only one eye?"

"It was figuratively spoken. Now, good night Yuu-chan!"

"...Don't call me that"

"Just sleep will ya."
