AN:
Another "oneshot" of mine. Well, oneshot for now - am considering to write more for it, depending on whether people still care about this ship/fandom.

If you want this to continue, just leave a review saying so~

(Next part would be smut, though. Probably.)

"Pretty, pretty pleeeease," the purple-haired purred. "I swear it won't hurt for too long!"

"That's a blatant lie and you know it! I'd never get rid of the scars." Shiena wouldn't agree, no matter what. The kinks of her roommate – if you can even call these sick perversions 'kinks' – were just too much for her. Who would possibly like being cut up as someone else gets off on that?

"You knew about that before being my girlfriend, don't complain now." Otoya pouted. For her, it wasn't any understandable that Shiena would refuse so vehemently.

"I did not become your girlfriend! We're not dating! You're hiding in my flat from the police." It wasn't only at this moment that Shiena regretted taking the serial killer in. She considered handing her out before, despite – or maybe rather because – she knows this girl well enough. But then again, she couldn't bring herself to do it. And up until now, Otoya was peaceful, so peaceful that one could almost forget what kind of person she was.

"We share food and shelter, same thing," Otoya reasoned. That was so far off from the same thing that Shiena didn't even see any reason to try and argue. But before she could get up, Otoya pressed up against her, both of them still in pyjamas – the same they already wore when they were in the Black Class.

"I'm going to lick up aaaall the blood spilling out, no need to worry about dirtying anything," she purred into Shiena's ear.

Immediately, Shiena felt a shiver down her spine, as well as the urge to push Otoya away. Far, far away. "T-that's the least problematic part! Gosh, what is wrong with you?!" The serial killer immediately sensed an opening and smirked.

"Oh, so you'd like my slowly licking up all the hot blood dripping from small cuts in your skin?" Otoya smiled seductively, but her words carried such twisted meaning that Shiena felt her stomach turning, it was more than just sick. Yet, the playfully excited expression on her roommate's face made Shiena's face flush.

"W-would you just stop it? I need to work," she pushed off the serial killer to get up from the bed.

"You're just going to sit in front of the computer all day again," Otoya complained and followed her girl friend with a pout. Maybe she could still change her mind, after all? But that was unlikely.

Even in the afternoon, Shiena's eyes were glued to the screen in front of her, typing wildly on her keyboard. Otoya failed to comprehend how anyone could have fingers skilled enough to type at this speed without making at least two typos per words, but for some reason, Shiena could do that.

She brought another cup of coffee to Shiena's desk, for a lack of better things to do – after all, Otoya should not leave this flat…just to be sure – and rested her arms on the backrest of the other girl's chair, looking at the screen and trying to make sense of rapidly changing symbols and letters.

"How does this even make sense to you," she wondered out loud. Shiena barely moved since she started, and even now she would not take her eyes off the screen.

"Just does." Her answer was rudely short, but at least she responded. A sign that maybe Otoya could strike up some sort of conversation.

"Are you hacking someone again? For that what's-its-name group of yours?" Otoya barely looked up from the screen now as well, resting her chin on her arms. She was oddly fascinated by whatever was happening on-screen. Shiena seemed to have a bad influence on her. Shiena nodded, but the lack of answer made her realise that Otoya probably didn't catch that.

"Yeah. Could you please leave now, need to focus." Otoya hummed in response, she didn't really want to leave. It was boring with nothing to do, after all.

"How do you assassinate someone with hacking?" This never really made sense to her, however much she thought about it. Any weapon or violence, sure, that kills people. But how would someone die without being killed? Shiena sighed. She knew she wouldn't get around explaining, or Otoya would find a way to really disturb her.

"In indirect ways. Either it exposes someone's true colours so actual assassins go for the kill, or they're desperate enough to commit suicide," Shiena explains nonchalantly, as if it was the most normal thing in the world.

"Driving people to suicide is pretty low," Otoya commented, pouting. It was a boring way and seemed like such a cowardice way to kill someone.

"Anything beats getting off on cutting girls open, you lesbian sicko." Otoya grinned to herself, amused by Shiena's attempt to make her feel bad.

"At least my prey gets to see their killer, I'm not hiding in some dark room." Shiena gritted her teeth. She knew the serial killer was right and she knew very well that for an assassin, she was a coward. But she didn't mind, after all, she never wanted to be a murderer. It was a necessary evil, she told herself. But on the other hand, it was probably much easier to indirectly kill someone and never really face them.

Then, realisation hit Shiena – the serial killer didn't deny the last part.

"Wait, you're actually gay?" It wouldn't be that hard to tell, considering she targeted females. But, on the other hand, Shiena figured that the serial killer only went for girls because they were much easier targets. Usually a weaker physique, easier to win their trust as another girl.

"You couldn't tell?" Otoya couldn't help but chuckle at her flatmate's obliviousness.

"Sorry for thinking you're cut-sexual," Shiena pouted, slightly embarrassed that she was dense enough to never really consider Otoya being into girls. Good thing she made the serial killer sleep on the couch and locked her bedroom at night, not that she was dangerous because she was a lesbian. More because of the serial killer thing.

"That's not wrong either," Otoya softly wrapped her arms around Shiena from behind, still keeping the chair's backrest between them. "So, what about you?" Shiena swallowed. Hard.

"What do you mean?" She tried to sound as nonchalantly as ever, but due to the shift in the conversation her voice failed her enough to show Otoya just how uncomfortable this topic was.

"Of course, I mean what besides this hacking thing gets you going," Otoya purred. Maybe, just maybe she would get to wrap Shiena around her finger.

"Like I know," Shiena bit her lip. "It's not like I've ever had a crush on anyone." The serial killer was surprised by this confession, but even more because from the blush reflected in the dark screen she could tell that it was the truth. Hard to believe, considering Shiena is sort of cute, after all. And her body isn't bad either, although she could do with a bit more bust.

This mere seconds of silence felt awkward enough, especially because the serial killer usually never shut up. Shiena felt like she had to break this silence, and not directly facing her flatmate helped her courage.

"How did you find out? About liking girls, I mean." And yet, her voice broke a bit more than she would have liked it to. Otoya supressed a giggle, this question was just so naively cute. It made her really want Shiena, in her own twisted way.

"Not hard. I've always liked the female body, aesthetically. Falling for a girl wasn't too far away," she explains softly. This should lull Shiena in, definitely.

"Do you even kill girls you like?" Or not. Why does she even care about that?

"Yup, of course. I've killed all of them." Shiena frowned. That made no sense to her, like, at all.

"Wouldn't you ever want to stay with them for longer? I mean, if you really like them… I suppose that's how you should feel." Ahh, this naivety, Otoya swooned. How much she loved the fearful, crying expressions of naïve girls who just realise they fell into her trap.

"There's no helping it, I do like them but I just can't feel at peace with them unless I cut them open. It's fascinating, their expressions, the raw emotion… It's so unbelievably cute, I couldn't compromise on that." Shiena almost felt bad for this poor girl, it must be hard to be driven to kill your loved one by your urges.

Wait, why am I feeling sorry for a damn serial killer?! Shiena mentally scolded herself, she shouldn't feel bad for such a person. And yet, she did.

"Why do you kill them? Why don't you stick to just cuts that won't kill?" Otoya smirked, in a way that Shiena didn't catch that. She knew she had Shiena just enough to know that it was only a matter of time anymore, such empathetic, naïve girls were just too easy. Even one who knew she's not an innocent girl.

"They'd call the cops if I wouldn't kill them. I'm already a murderer, remember?" Shiena understood that much. Which girl would trust a serial killer to not go for the final blow? Probably none.

"If you wouldn't have killed your first girlfriend, maybe she'd be fine with it." Out of Shiena spoke reason, very naïve reason but still a possibility.

"Would you be fine with it?"
