Warning: There have graphic violence into this chapter.

"Wait, Otoya! Don't do this, stop!"

Shiena was desperately calling her girlfriend, trying to stop her urge to kill toward Tanaka. The brunette was running into the building where was her apartment, searching for Otoya. Even if she wanted to stop the serial killer from killing Tanaka, Shiena didn't know how to resolve this problem. The bully had now something against her that could send her directly into prison. Hiding a serial killer was a crime that cannot be unpunished. This problem was different than the one with Midori. The green haired girl was also an assassin, she couldn't denounce Shiena to the police without the risk of being her too arrested. Tanaka, even if she was a nasty bully, didn't do any crime. The brunette had nothing to keep her silent about her relation with Otoya. Killing her seemed to be the only solution, but Shiena still refused to accept this solution.

Shiena arrived to the building's exit, but Otoya and Tanaka wasn't there.

"Maybe they left the building" thought the brunette, worried.

The brunette suddenly heard a scream, coming from the building's basement. Even if she found that weird that Tanaka ran away into the basement, Shiena began to run, heading to the scream's provenance.

Tanaka didn't really know well this building. She couldn't think well either, with a serial killer who was pursuing her with murderous' intentions. Terrified and confused, the bully lost herself and took the wrong door, to finally arrive into the basement. She was trapped into a dead-end, at the mercy of Otoya. Cornered against a wall, Tanaka was shaking from fear, while the serial killer approached from her, armed with a scissor.

"You can only blame yourself, Miyo-chan. You're the one who ask for it, by putting your nose into other people's business" said Otoya.

"No please, don't kill me! I swear, I won't say anything about you and Kenmochi" tried to beg Tanaka.

The serial killer laughed a little bit of Tanaka's cowardice.

"Begging never work on me, in the contrary, that increases my urge to kill" began to say Otoya. "But you know, it isn't the only reason why I'm gonna kill you. I'm pretty sure you're one of the bullies who hurt my girlfriend in the past, and I can't forgive you. Every person who tried to hurt Shiena deserves to die!"

"D-don't tell me that...you're the one who killed them, the other bullies…?" asked Tanaka, remembering her first accusation against Shiena, that the brunette asked to someone else to kill the people who bullied her.

Otoya didn't understand what she was talking about, but she decided to play the game to torment Tanaka.

"Maybe it was me, maybe it wasn't me, who know?" answered the serial killer with a smirk.

Tanaka screamed when the serial killer began to approach from her. Otoya was walking slowly and cutting into the air with her scissor. She wanted to play with her future victim a little bit, to terrorise her before killing her. She wanted to make suffer this bully who dared hurting her girlfriend. Arrived in front of Tanaka, Otoya grabbed her by her blond hair and approached her scissor from her face, menacing.

"You know, the last girl who dared touching my girlfriend, I personally gouged one of her eyes with my scissor. But, in your case, you were far worst toward Shiena than her, so maybe I should gouge your two eyes, don't you think so, Miyo-chan?"

"That's enough Otoya, let her go!" shouted Shiena, who just arrived into the basement.

Otoya turned herself, to see her girlfriend. She let Tanaka and approached from the brunette.

"But Shiena, if I don't kill her she'll bring you trouble, I can't allow this" tried to explain Otoya.

"I don't want you to kill for me, I already said it to you. Remember, with the client you killed…"

"You said that you didn't want me to kill if it's a minor problem. Well, this girl isn't a minor problem, she's definitely a major one. If I let her live, you'll go to jail, this is serious!"

"Killing is never the right solution!" said Shiena.

Surprised by this answer, Otoya approaching from the brunette and began to whisper, she didn't want Tanaka to hear their conversation. The serial killer kept an eye on her, while Shiena was back to the bully.

"You're an assassin, aren't you? Then, why do you despise killing?" asked Otoya.

"I consider myself an assassin because I work for a group of assassins and I already killed before, only one person, and I hated it"

"Listen Shiena, if we spare this girl, she'll tell to the police that you hid a serial killer and you'll go to jail. If you don't want to kill her, what other option you propose to rid from this problem?"

The brunette already knew that killing her was the only safe solution, but she didn't want Otoya to kill for her, and she didn't want to kill either. Shiena only killed one person in her life, and it made her sick for a long moment.

"Maybe I can ask help from my organisation, since Tanaka is a bully, maybe they could…" began to say Shiena.

But before that the brunette could finish her sentence, Otoya suddenly pushed her on the floor.

"Watch out!" shouted the serial killer to her girlfriend.

Tanaka was running into their direction, with a stick she found, ready to hit Shiena. Otoya had pushed her to protect her, but it was too late for her to stop the stick. The bully violently smashed it on the serial killer head. Otoya felt on the floor, blood coming out from her scalp. Shiena rushed toward her girlfriend, worried about her condition. Otoya wasn't unconscious, but the stick hit temporally paralysed her body. She was laying on the floor, on her belly, inert, her eyes still open. On the spur of the moment, we could easily believe that she was dead.

"Otoya, no!" shouted the brunette, about to cry.

Shiena touched the serial killer's neck, and with relief, she noticed that her heart was still beating. Tanaka approached from her, a vicious smile on her face.

"Too bad, your protector can't protect you anymore, fluffynerd" said the bully meanly. "Who could know that you were a lesbo? In addition from being a nerd, you're also a fucking dyke! You are the perfect example of what a dork is. Why do you think people like to bully you? Because you're a trash, someone like you don't deserve to be respected, you can't even protect yourself, you need other people to get rid from the one who bullied you. You're a coward, a fucking dork! But, unlike this other dorks, you're also a criminal, you can go to jail. I hope you will enjoy you time in prison, with the other lowlifes! About your serial killer girlfriend, she will probably face the death penalty" taunted Tanaka.

Somehow, the bully had right. Shiena always relied on others to get protection. She relied on her organisation, and also on Otoya. But she could accept what Tanaka said to her. She never do anything wrong to be bullied. This wasn't her fault, it was the bullies fault. Yukarin said it to Shiena, it was never the victim's fault, but always the aggressor's fault. All this bullies, they had no right do this did to her. Tanaka had no excuse for what she did. Because of this bully, Shiena couldn't trust others. Tanaka had tried to ruin her life, and she was still trying to. Because of her, she might go the jail and Otoya could be executed. Shiena couldn't allow this, she couldn't let Tanaka ruin her life anymore. She was to get rid of this problem by herself, not by relying on others. She needed to protect her life and the girl she loved at any cost.

"S-Shiena, what are you…doing?" managed to ask Otoya.

The brunette's eyes began empty when she took the serial killer's scissor. In her head, Shiena could only hear one thought.

A girl like Tanaka Miyo certainly didn't deserve to live anymore, she needed to be eliminated.

Everything was dark around Shiena. The brunette had a blackout, she didn't remember exactly what happened. All she knew was that she couldn't see anything and that she heard a girl screaming from agony. This voice, Shiena recognized it. It was Tanaka who was screaming, the brunette was certain. She also felt a strange liquid on her hands, which seemed to splash on her body. The liquid was hot a more dense than water. Suddenly, she heard another voice that was calling her, a familiar voice.

"Shiena!"

It was Otoya, the brunette could easily recognized her girlfriend's voice. Suddenly, Shiena recovered her sight. She saw the serial killer in front of her, who seemed to have difficulty to stand up.

"O-Otoya…?"

There had something weird about Otoya's expression. Her cheeks was red, like she was blushing, she seemed to be excited by something. But also, Shiena could see anger into the serial killer's eyes, like she was frustrated or maybe even angry at her. The brunette wasn't sure, but it looked like jealousy into Otoya's gaze.

"What happened, why you are looking me like that?" asked the brunette, confused.

Shiena suddenly noticed that she was sitting on something soft. It was with terror that she discovered what it was. She was on top of Tanaka's bloody corpse. The bully's chest seemed to have been stabbed repeatedly with a sharp object. What caused her death was the stabbing into her throat, which made her bleed to death. Shiena had still her hand on the murder weapon, a pair of scissors, which was still into Tanaka's throat. Her hands were dirtied by blood and her body was covered from the bully's blood. Shiena uttered a scream from terror and recoiled from the corpse. She crawled into a corner and she curled up, petrified. She didn't remember anything of what happened.

"Shiena, don't worry, I'll fix this. Stay here, I'll go searching some stuffs to clean this mess" said Otoya with a shaking voice, which wasn't her usual self.

With some hesitations because of her girlfriend's state, the serial killer left the basement. Shiena approached slowly from Tanaka's corpse, confused and terrified.

"Am I the one who…no, it's impossible, I couldn't do something like that and don't remember, it should be Otoya, but…" thought the brunette.

While Shiena was removing the scissor from the bully's throat, she heard someone walking behind her and she blenched. How it was possible? The brunette didn't see anyone coming into the basement, where this person came from? Maybe this person entered when she had a blackout, but Otoya should have seen this person and told her.

"Kenmochi-san…what have you done?!"

Worried, Shiena turned herself, to see the person. It was a terrible shock for her when she saw her teacher, Kamikuro Reiko, who was gazing her, emotionless.

Well, I finally killed the bitch...wait, that was the wrong bitch, dammit! This teacher is definitely suspicious...
