A/N: Working on a new story. Might take a bit of a left turn in a while, but just hang on tight. I wasn't done writing, but I was so ready to post this, so you might have to wait a little for the next few chapters. Nevertheless, enjoy.

"This is our new friend! Make sure everyone is nice to him, alright?"

Len didn't like him from the very start. While everyone else rushed over to ask questions and introduce themselves, he remained at the back of the group, arms over his chest, indignant. Even when Master gave him a nudge toward the group, he stood stock still, glaring at the blue-haired menace. He'd hiss if the others hadn't been watching him, but he was sure the steely look in his eyes was enough.

"What's your name? I'm Miku!"

Holding her hand out, Miku was met with a bow, which took her a little off guard.

"N-nice to meet you. My name is Kaito."

"Waah! He's so proper!"

Len's annoyance only proved to be doubled once he saw that his sister accepted the stranger. The next few minutes were spent in the kitchen, everyone asking various things about the new Vocaloid that he responded to with a degree of bashfulness. Each laugh he could ellict from one of the others set Len on edge, and the blond finally decided to move up to his room before he was yelling. He wanted to stay as far away from the newcomer as possible, and getting into an argument with him would have only proved counterintuitive.

Besides, the others would only berate him for it. They saw him as an innocent new singer willing to join the group. Only Len saw the true menace underneath it all.

"Kaito is so cute!"

Rin burst into the room, trotting over to land on Len's chest and catch him in a bear-hug while she continued to squeal over Kaito. The blond managed to pry his sister off of him and rolled away to face the wall with a huff. Still smiling, she sat on the edge of the bed cross-legged and put a hand on her twin's shoulder.

"You're jealous, aren't you?"

"What!?" He turned back to her, jolted up. "I'm not 'jealous'. I just don't like him, ok? He looks like a total jerk..."

"Well you won't know until you finally decide to meet him, right?" She leaned forward to whisper, playfully. "Spoiler alert: he's super nice."

"Oh, be quiet. I don't wanna meet him. I'm not gonna talk to him."

Rin jumped up, then promptly trotted over to her side of the room, opening a chest of drawers.

"Well whatever. Master will have you singing with him in no time, and you can't say no to him."

Turning back to face him, she flung a purse over her shoulder.

"And where are you going?" Len slumped back into a lying position.

"You don't care."

"Fine, whatever."

"C'mon, lighten up, Len. We were going out for ice cream to celebrate for Kaito."

"Why? He hasn't done anything worth celebrating."

"Yeah, but he loves ice cream. You can come too, if you promise to be nice..."

"No. I'm not going anywhere if he's going too."

"Then I guess you won't be leaving the house anymore, 'cause he's one of us now."

With a final overenthusiastic spin, she left the room, only sparing a small wave for Len. He shoved his head into his pillow, feeling the urge to yell once again, but deciding to listen to his music instead.

"I don't need them. They can make friends with him if they want, but I'll be right in the end. I can just look at him and tell he's no good."

He managed to drift off to sleep without even noticing, holding on to his pillow and letting his music fuel his dreams. About an hour later, the room door was slowly pushed open, letting the light from the hallway flood in. A shadow loomed across the room, looking eerie as it splayed across the yellow curtains and over Rin's empty bed. When Len shifted, the intruder stopped, but was quickly sneaking forward once more. It settled next to his bed. A hand reached out to Len's shoulder as the blond was waking, and-

"Aaah!"

The blond shot up, but, too close to the edge, slipped off of the bed. Just after an adjoining scream ended, his eyes were up in a glare. His heart was pounding in his chest. His rage was only sparked anew. Of course it had to be Kaito.

"Is everyone okay?"

Master rushed into the room, accompanied by Gakupo, Rin, and a less-than-worried Miku. With the light switched on, the scene was exposed.

"Kaito just snuck into my room! He was probably trying to steal something..." He started under his breath, "Or maybe kill me in my sleep..."

"What? No! I was just going to ask if you wanted some ice-cream. Rin said you weren't feeling well, so I thought you would feel left out..."

"Kaito," Rin had taken a guilty and simultaneously sympathetic look. "You-didn't have to do that."

"I'm sorry, please don't be upset with me."

"No one is upset, Kaito." Master was the first to respond.

Len, though, was incredulous.

"I'm upset! He just snuck into my room without permission!"

"Our room, you mean." Rin took the time to settle onto her bed. "And I'm sure it won't happen again, Kaito just has to get used to everything."

"So no-one's gonna take my feelings into account? Everyone is on his side 'cause he's new?"

Miku yawned, stopping any possible responses to Len's argument. She'd already been dressed in her pyjamas and seemed absolutely nonplussed with the situation.

"Can we all just get some sleep? We'll feel better in the morning, I know I will, anyway."

"Miku is right," Gakupo chimed in. "Let's all get to bed, okay? We'll talk this out in the morning."

As everyone left, agreeing with the sentiment, Kaito took a moment to turn back to Len and utter a silent apology. The blond only glared back at him as a response.

"Len..." Rin whispered across the room.

"What?"

"Give him a chance."

"A chance to murder me in my sleep? No thank you."

"Whatever, Len."

See you next time.
