Reiko grabbed her injured arm. Otoya was still pointed a gun at her. An irritated and furious expression appeared on the teacher's face. Luckily for her, the serial killer was a bad shooter. Indeed, Otoya was better with cold steel than firearm.
"You…how did you find me?" Reiko asked.
"Midori-chan told me everything about you." Otoya answered.
"Sasoriza Midori? I thought she was already dead…"
Otoya pulled the trigger. Strangely, nothing came from the gun. There was no bullet anymore. Reiko smirked when she realized that. While her arm was heavily bleeding, the teacher rose up and pushed Otoya, running away from the bedroom, letting the two girls alone. Otoya rushed toward her tied girlfriend, worried. She quickly removed the tape gag.
"Shiena, are you alright?!"
"Y-Yes…I mean, not really…I don't know."
Otoya untied the brunette and helped her to sit, while Shiena buttoned her shirt. Suddenly, Shiena began to cry from regret.
"I'm sorry, Otoya. I should have told you where I went and I shouldn't have trust Kamikuro-sensei…"
As soon as her girlfriend began to cry, Otoya immediately hugged her.
"Idiot, I'm not mad at you, not need to be worry," she began to say. "Stop crying, I'm here now, I won't let her hurt you anymore."
Otoya gently wiped Shiena's tears.
"You said that Sasoriza helped you, how is that possible? She as been executed…"
"She's probably dead now, she was about to face death penalty when she called me." Otoya answered. "Her dying wish was to save you, she told me everything about your twisted teacher. I don't like Midori-chan, but I'm grateful to her. She's the one who told me her address."
Otoya threw the gun away. It was Shiena's one, she found it in her bedroom. Unfortunately, she didn't bring munition with her.
"I see, Sasoriza is dead now…" Shiena sadly said. "And her last request was to protect me from Kamikuro sensei."
"According to Midori-chan, there have a rumor in your organisation about a 'serial bully'. A lot of students were bullied in a similar way, and they are all dead now. Some of them commited suicide and the others became bullies and get killed by assassins from your group."
Shiena knew this rumor. Before she participated to the Black Class, she tried to find this murderous bully, in vain. In the absence of evidence, the brunette thought it was just a rumor based on coincidences. But after what Reiko told her, she began to have doubts.
"Midori-chan investigated on Kamikuro. She has been the teacher of every victim until now. This is what all the serial bully's victims had in common. Kamikuro is also the one who added the name the victims who became bullies on the black list. Though, she never killed them personaly…"
"You mean that…Kamikuro-sensei is the serial bully?!"
"Probably, and…she's the one who caused you to be bullied." Otoya said.
"I already know…"
The two became quiet. Shiena was terribly shaken by what she learned today. Her dear teacher and first crush did terrible things to her. It was because of Reiko if she was bullied. Also, she was a notorious bully, Shiena couldn't bear that she had liked such a person, that she deeply had trusted Reiko. She felt ashamed to have trusted such a horrible person and she felt guilty to have let her killed the Mikage twins. The brunette couldn't stop herself from crying again.
"No, please Shiena, don't cry…" Otoya begged.
Desperate to see her girlfriend crying, Otoya suddenly kissed her. She wanted to comfort Shiena, seeing her being sad was almost a torture for Otoya. After such a horrible day, the brunette appreciated this sweetness from her girlfriend. Suddenly, Otoya pushed her on the bed, astride Shiena.
"Sorry Shiena, but right now, I just want to comfort you in my way…"
"W-Wait, you mean you want to have…huh, here? But…Look out!"
Otoya immediately turned back. Reiko was in the door frame, a gun in her hand. She had bandages on her injuried arm. The teacher had both girls at gun point, a grin on her face.
"Hey, what were you about to do in my own bed?" Reiko asked, even if she already knew the answer.
"Kamikuro…sensei? Why are you still here!?" Shiena asked, panicked.
"You really thought I left? That's my house you idiots! Now get out of my bed." Reiko ordered.
Otoya and Shiena obeyed and rose up, recoiling from the bed. Reiko was still threatening them with her gun.
"Is that true? Are you the serial bully?" Shiena asked, with a shaky voice.
The teacher smiled in a disturbing way.
"Yes, it's me." Reiko admitted.
"Why? Aren't you supposed to hate bullies? You're a member of Collective Dismissal! Why are you a bully? How could you do this…" Shiena said.
"I already told you why. In a bullying case, I hate both the bully and the bullied. Bullies are despicable and bullied kids are so weak that it's disgusting." Reiko answered.
"How could you become such a horrible being!?" the brunette asked, furious.
"I told you that past is irrelevant. Knowing why I became like this won't change the person I am right now. In the present, I'm a bully, this is all that matter, Shiena-chan. Now get out of my bedroom, it's time to get serious…"
Otoya and Shiena were kneeling on the floor, in front of a wall. They had their hands raised on their heads. Reiko was behind them, still pointing them with her gun. They were in the living room.
"So, which one I kill first?" Reiko meanly asked.
The two girls remained quiet. The teacher approached of them, pressing the gun against Shiena's head.
"I'm kidding, I won't kill Shiena-chan, she's a too precious toy for me." Reiko said, before pressing the gun on the serial killer's head. "Then, Takechi-san, I should instead blow your head up in front of your dear girlfriend…"
"No, please, don't kill Otoya!" Shiena begged.
Panicked, the brunette rose up and tried to stop her teacher. Reiko hit Shiena with the gun on her head. Her student fell on the floor, inert.
"Shiena!" shouted Otoya, trying to reach her injured girlfriend.
The brunette was bleeding from her forehead.
"I'm…ok, don't worry, Otoya." Shiena weakly said.
Reiko suddenly grabbed Otoya by her hair, forcing her to recoil from Shiena.
"Since it's because of you if I lost Midori-chan, you will replace her. I'll continue my experiments on you, Takechi-san." Reiko began to say. "Or, I have a better idea! I should force you to see your precious girlfriend being torture and raped by me, and after I'll kill you just in front of Shiena-chan in a horrible way."
While listening to Reiko's gruesome projects, Otoya discretly put her hand under her jacket, searching something.
"Speaking of Midori-chan, there have something I have to tell you." Reiko began to say. "Since I lied to my group when I told them I've killed her, I told everything I know about her to the police. This is why the police knew she was a murderer. We could say that it's my fault if she's dead now. Well, she probably would be arrested and executed one day, but not so fast."
Reiko laughed at her own cruelty. Shiena was terribly angry. Even if she somehow disliked the green haired girl, she couldn't be insensitive about her death. Suddenly, Otoya took out a pair of scissors and stab the teacher in her leg. Reiko uttered a scream of pain and fell on the floor, before shooting Otoya. Shiena was shocked and panicked when she saw blood coming from her girlfriend's belly. The serial killer fell on the floor, inert.
"You bitch, just die, you're such a bother to me." Reiko said to Otoya, scorful.
In a fit of rage, Shiena rose up and tried to attack her teacher. Reiko hit her with her gun and pushed the brunette on the floor. She began to violently kick Shiena with her uninjured leg.
"You should learn your place, Shiena-chan! Don't worry, I'll train you properly, you'll be my obedient pet…" Reiko said, still kicking her student.
Otoya suddenly rose up and grabbed Reiko by behind, forcing her to throw her weapon. Shiena hardly rose up, after that she took Otoya's scissor. Without hesitation, she stabbed Reiko in her belly. The teacher uttered a painful scream, before falling on the floor.
"Otoya! Are you alright?" Shiena asked, worried.
"I'm ok, the bullet only scratched me." Otoya answered.
They both looked at Reiko, who was still on the floor. The teacher was breathing, she seemed to be alive. There was a lot of her blood on the floor. Shiena took her gun and pointed Reiko.
"I want to know why you became like this, Kamikuro-sensei." Shiena asked.
"Give me the gun, I'll kill her, you don't have to dirty your hands for someone like her." Otoya offered.
"No, I have to do this, I'm her victim after all, the only one to be still alive. I'll avenge the others." Shiena said.
Reiko weakly laughed, while spitting blood.
"My past isn't important, but if you want to know, I'll tell you. But promise me to not change you intention toward me." Reiko said.
"Don't worry, whatever you'll tell me, I'll still kill you."
The teacher smiled, satisfied by her student's answer.
"When I was around your age, they had a girl in my class who was bullied. I tried to help her but she always refused my help, saying that she had pity of her bullies. She was too kind, she was soo weak. She didn't want to hurt the bullies. Her attitude pissed me off, I was so angry after her that I also begin to bully her. I only did it for a week, I didn't like to do this. But, what I did encourage other classmates to also bully her. After a month, the bullying was so cruel that she commited suicide. I felt so guilty for this, I only have joined Collective Dismissal to atone my fault. It didn't work. I saw this girl in every bullied kid. I began to be mad at her, to consider that it was her fault if she killed herself, because she was too weak. This is why I became a bully, I wanted to see if it was really my fault if she commited suicide, by experimenting on other bullied kids. I finally became a monster unable to feel guilty, so I was happy. When you became an assassin, I was relieve too see that not every bullied kids were weak. This is why I couldn't support it when you began to be too soft. I have too admit that I kind of like you, Shiena-chan."
Shiena listened to her teacher, still pointing the gun.
"You became such a monster that you continued to bully just for your own pleasure." Shiena said. "You're the kind of bully our organisation should kill! As a member of Collective Dismissal, I'll kill you, Kamikuro Reiko!"
Shiena's hands were shaking, she was hesitating.
"Shiena, don't forget your promise, you have to kill her." Otoya said.
"I know!" the brunette said, before speaking to her teacher. "Even if you ruin my school life, without this, I wouldn't became an assassin and a surely wouldn't meet Otoya. Maybe I should thank you, without you, I wouldn't have meet the girl I love. I would probably still be the weak girl I was. So thanks and good bye, Kamikuro-sensei. I also have…liked you."
Shiena pulled the trigger, shooting Reiko in her heart, killing her instantly. Suddenly, the sound of police's cars could be heard outside.
R.I.P Kamikuro Reiko. btw, this character is inspired by Kamishiro Eiko, a character from Jigoku Shoujo.
Otoya's logic: Hey, let's have sex in your teacher's bed right after she abducted you.
Huh? The police is there? Why?
