Hi! Here's another chapter of this headcanon, this time it's the OtoShie one. Enjoy!

Her teacher was lying on the ground, whimpering in pain, a blood stain on her hip. Well, her substitute teacher, she was just there for a week. It was all it took her to screw up everything.

"This is your fault if I stabbed you, Kenmochi-sensei," she said, holding a bloody pencil. "You just had to not be that nosy…"

"You…I had to. You…you killed…it's..wrong, I had to stop you…!" Shiena weakly exclaimed.

Kenshi Ryuka glared at her teacher with animosity. How dare she say something like that?

"Those scums, they had it coming. Always messing with me, putting me down, thinking that they were better than me. Those assholes…they deserved to die. The world is a better place without those trashes."

"I'm…sorry…for what they did to you. I understand you. I used…to be like you. But killing is just…wrong, no matter the reasons. You went too far, Kenshi. You'll be…in big trouble. You can't…get away with this."

"Shut up! I'll get away! I just have to kill you, there's only you who knows I killed them. Without you, no one will know, I'll be safe."

"Please, Kenshi…don't do that. It's not too late. Don't do something you could regret."

"Uh? Regret? I don't care about who I kill. They all deserved it, and so do you, for putting your nose in my business. You're just like all those other scums, you're just pretending to understand me, you're looking down on me like everyone else! Scums like you…they all deserve to die!"

Ryuka raised her pencil, ready to end Shiena's life. But she couldn't. Something was stopping her. It was the lack of hatred, of rage, anger. Without those, she had no will to kill. And despite how annoying Shiena was, she did nothing to fuel Ryuka's hatred.

"How strange…I don't feel like killing you. But I'll. Otherwise, you'll just go tell the cops about me..,"

"No…I won't…I…I can help you…"

"Liar! There's no way I can believe you. You're just trying to deceive me like everyone else!"

"No, it's wrong…trust me…please."

Ryuka couldn't hear it anymore. Shiena was definitely trying to manipulate, just like everyone kept doing. She had to kill her, it was her only solution.

But suddenly, someone grabbed her from behind and forced her to turn back. She met a pair of cold and threatening eyes, the gaze of someone who could kill her in an instant without a second thought. Ryuma was paralyzed with fear, thinking that she was about to die. The other person raised something sharp, ready to strike.

"Otoya, no!" Shiena begged. "Don't kill her!"

The other woman suddenly stopped. Ryuka felt her heart skipping a beat.

"But Shiena-chan, she stabbed you, and tried to kill you. Why should I spare her?"

"Because…I understand her. It's not her fault. Everyone…keeps pushing her around. She doesn't deserve to die. So please, don't…kill her."

Otoya looked like she hesitated, before she lowered her scissors. A sudden cheerful expression and a warm smile appeared on her face, much to Ryuka's confusion. She couldn't believe it was the same person who was about to kill her a few seconds ago.

"You're lucky kid that my Shiena-chan has a pure heart. Otherwise I would have slice you up ~"

Ryuka looked at Shiena, who was still lying on the floor, in pain. Pure heart? Did such a thing even exist? To Ryuka, every human was rotten and should just die. But this woman, she was…good. She indeed had a pure heart, Ryuka was able to see it. No one in her life ever protected her, Shiena was the first one. She didn't know that such a person existed, someone who could understand her.

Ryuka smiled softly. She finally found someone in this world who truly deserved to live.

Shiena's hip still hurt. The stitches were uncomfortable. But at least she was not bleeding anymore.

The perpetrator of this wound was currently sitting in her living room. Shiena recalled how all of this began. She just accepted to act as a substitute teacher to investigate the serial murders in a school, a mission from Myojo Academy. Let's say that after she tried to hack them, Shiena was forced to work for them on several occasion. From what she understood, Myojo wanted to recruit this young serial killer. But somehow, Shiena managed to make Ryuka looked like a bad choice, making her look like she was too unstable to be a pro assassin. To protect her. Which was not entirely false.

"Kenmochi-sensei…why did you invite me here? Why haven't you call the police yet? I mean, I'm a killer, and I hurt you," Ryuka said, confused.

"Because….You know, I still wonder. I think it's because…I don't want you to end up in jail. I want…to help you. Isn't what I told you? That I could help you."

Otoya was observing the scene with curiosity in her eyes, but didn't know any signs that she wanted to participate. Ryuka looked kind of doubtful.

"Why would you want to help me? No one even wanted before," Ryuka said.

"I…I'm not sure. But…tell me…where are your parents?" Shiena asked with hesitation.

"Dead. Those two scums were junkies, always messing with me and everyone around them. The law didn't exist for them, as well as rules. And it bites them in the ass, they got killed."

"How?"

"By some gang leaders because they stole drugs from them. I saw everything. It was super bloody. They had it coming, those assholes."

"I see….um, then, where are you living right now?"

"In a foster family. Not that they care about me. I feel like they don't even know I exist. They would gladly get rid of me if they could."

Shiena finally understood why she wanted to help Ryuka so much. it was because, somehow, she reminded her of herself. A darker version of herself. Parents who neglected her, feeling like others didn't know if she existed, and the bullying. Shiena couldn't help but thinking she could have ended up like Ryuka if things had been more rough for her. Then again, Ryuka also reminded her of Otoya. A serial killer who hid behind a charming mask. Ryuka completely fooled everyone at school, including Shiena, always acting polite, decent, helpful and nice. Her mask was calmer than Otoya's cheery one, but they were both hiding their true self under a mask. But unlike Otoya, Ryuka wasn't born that way. She was made that way because of her life experiences. One was a psychopath, the other a sociopath. Shiena couldn't help but want to avoid her becoming even more like Otoya, because deep down, she regretted to not be able to change what kind of person her girlfriend was. Shiena couldn't help but think "If I can at least save that girl, then perhaps I'll be forgiven to have fallen in love with someone life Otoya".

"Kenshi…Ryuka…how about…I become your legal tutor?" Shiena proposed.

"Uh? Really?" Ryuka reacted, even more confused.

"Are you sure about that, Shiena-chan?" Otoya said, finally taking part in the discussion.

"I mean, her foster family doesn't seem to care about her, while I do…I think I would be better than anyone to take care of Ryuka. What do you think, Ryuka?"

A wide smile appeared on the young girl face, a smile that appeared sincere.

"I would love it! I also think Shiena-chan is the best person to take care of me," Ryuka replied.

"Shiena-chan!?" the brunette reacted.

"Well, yeah, since we're family now, it sounds better than calling you Kenmochi-sensei. Does it bother you?"

"N-No, it's fine…"

Suddenly, Ryuka hugged Shiena, which the latter didn't protest. Otoya suddenly opened her arms, with a big smile on her face that meant no good to Shiena.

"Mind if I join?"

"…sure," Ryuka said, looking unsure about how she felt about Otoya.

Otoya hugged both of them. She looked happy, but Shiena knew she must have bad intention, as always. Regardless, Shiena was glad. She'll be able to use what she learned by living with a serial killer to help someone. She felt useful, and she hoped things would work out with Ryuka. Anyway, it looked like she got herself a daughter.

For those of you who had read The bully and the bullied (the original), perhaps you remember a character named Fuka that appeared at the end of the fic. Ryuka is basically this character, but with a new name. So yeah, Little devils and B&B are somewhat connected, they are all part of my own AnR universe.

I hope you like it and see you next time for the SumiBanba one-shot!
