Shiena slowly opened her eyes. It took her few seconds to realise what happened. She looked around her. The brunette was in an unknown bedroom and the only light source was a lamp beside her, on the nightstand. When she tried to rise up, Shiena began to panic. She couldn't move. It took her a moment to notice that she was tied up. Her arms and legs were tied to the bed she was laid on. She wasn't alone, someone was sat beside her on the bed.

"Kamikuro…sensei…?"

The teacher began to stroke Shiena's cheek and showed her a sweet smile. The brunette couldn't know what Reiko's intentions were. Even in her actual situation, when Shiena saw her abductor, she could only see her dear teacher.

"It's a misunderstanding, huh? There have a reason why you did this…"

"No, this is exactly what it looks like." Reiko said.

Shiena was shocked. The teacher she liked and admired, which was also her first crush, really abducted her.

"Why? Why did you do this, sensei?"

"Because you tried to run away. It's my fault, I underestimated your feelings toward Takechi-san. I thought that I could seduce you easily, but I was wrong. Don't have the wrong idea, I'm not in love with you, even if I have a deep affection for you, my dear student."

Shiena was hurt, to know that her dear teacher played with her like this was painful.

"Why you did this to me? You tried to ruin my relationship with Otoya!?"

"Yes, I don't like your relationship with her. First I was impressed that you could control this dangerous serial killer, but now that you're in couple with her, you became too much soft."

"I don't control her, this is mutual love!" Shiena protested. "Kamikuro-sensei, you manipulated me since the beginning, don't you? How could you, I trusted you, you said that you were my ally…"

"Oh, but I really care for you, Shiena-chan. I care as much as I care for my favorite toy!"

Even if she said such harsh words, Reiko was still smiling kindly, petting Shiena's head.

"You're horrible, how could you fool me!? I really liked you, I had a crush on you when I was younger…" Shiena said.

The brunette couldn't stop herself from crying. She felt betrayed by someone she really trusted, someone she was sure couldn't hurt her.

"Oh please Shiena-chan, don't cry. I'll tell you something funny to comfort you, okay? Do you want to hear something funny?"

Suddenly, Reiko's smile became more sinister and even twisted.

"Mikage Tatsuya and Mikage Hiyori were perfectly innocent!" Reiko said.

Shiena remained silent for a moment, she couldn't believe what she just heard.

"Don't tell me…you forced them to bully me!?" Shiena asked.

"I said that they were perfectly innocent, they didn't do anything to you. I was the only culprit."

The brunette almost lost consciousness when she heard this confession. Reiko violently slapped her in the face.

"Please Shiena-chan, stay awake."

Reiko wasn't smiling anymore. She looked really serious. The brunette was really afraid, she realised how much her teacher was dangerous.

"But…Tatsuya was on the black list…and Hiyori tried to kill me. That doesn't make any sense!" Shiena screamed.

Reiko slapped her once again.

"Don't scream please, this is painful to hear." threatened Reiko. "The Mikage twins were never been bullies. I put Tatsuya's name on the black list, this is why he was killed. I told Hiyori that I abducted her brother and I told her to kill you if she wanted to see her brother again. This is probably what she tried to tell you before I shoot her to death."

That was a horrible thing to hear for Shiena. The Mikage twins were really her friends, they were perfectly innocents.

"You…killed two innocent people, two of your students…"

"It's not like it was the first time I caused the death of some of my students." Reiko said. "I hope you clearly understand what I did, Shiena-chan. I'm the one who hacked your computer, wrote 'flufflynerd' on your door and locked you into a freezer. I called this person, Namatame Chitaru, with your cellphone, because I wasn't sure if Takechi-san would be able to save you. The Mikage twins never stole my laptop, it was a lie."

Reiko just confirmed that she was the only culprit since the beginning. Even if Shiena had a doubt on her teacher, she didn't want to suspect her. She was convinced that it was all a conspiration from Myojo Academy. The brunette understood how much she was wrong.

"Why you did this to me!? What's the point, you wanted to make me suffer? Do you hate me that much?" Shiena asked.

"I already told you why. You became too soft, you became boring to me. Having friends made you weak! I worked too hard in order to make you strong, I couldn't let you become like you were before, a weak bullied kid. I hate bullies, but I also hate bullied kids."

"Wait…what does that mean? How could you make me strong?"

Suddenly, Reiko began to laugh in a sinister way, which really worried Shiena.

"The first time I saw you, I knew that you were bullied when you were younger," Reiko began to say. "You were afraid of everyone and you didn't have any friend. I hated you for your weakness, I wanted to toughen you up. That was my duty as your teacher. This is why I wrote on your desk 'fluffynerd', I wanted to see how you would react if you were bullied again."

This was too much, Shiena couldn't bear what she just heard.

"You…you are the one who bullied me first!? This is all your fault, you ruined my life, you"re a monster! I hate you!" Shiena shouted.

"I told you not to scream!"

Suddenly, Reiko opened the nightstand and took a duct tape roll. The teacher cut a piece of duct tape and put in on Shiena's mouth to gag her.

"I only wrote this on your desk, I didn't do anything to you after. It's not my fault if some bullies began to pick on you after. You looked like a bullied kid, this is normal that you attract bullies. Even if I didn't write this, they would probably bully you anyway!"

Shiena would want to scream "shut up", but she couldn't. The brunette could only utter some muffled sounds.

"Even if I only did this to experiment something," Reiko continued, "I really have affection for you now. The other bullied kids I had targeted committed suicide or became bullies. If they became bullies, I put their name on our group's black list and they get killed anyway. You're the first one who became an assassin. I was surprised when I discovered that you became a member of Collective Dismissal, I was kind of proud of you. I thought that you become stronger, a real assassin. I was happy when you killed Tanaka, but when you spared this Subaru girl, I was disappointed. But then, you killed this inspector. Maybe there have still hope for you."

Reiko began to unbutton Shiena's white shirt. The brunette tried to struggle, in vain.

"All those marks, it's your girlfriend who did this? What kind of activities you have together…maybe you love pain after all."

The teacher began to press on one of Shiena's wounds. The brunette uttered a muffled scream of pain.

"What a wonderful sound you make! Maybe I should kill Takechi-san just in front you, it will maybe toughen you up! How could you not become a ruthless assassin after seeing your girlfriend die? After all, you're the only one of my targets who survived, it means that you're special. I can't give up on you, I have to get rid of this serial killer. You'll be mine Shiena-chan, both your body and mind will be mine…"

The door suddenly opened. Reiko turned back. She couldn't believe what she saw. How could this person be there?

"Get your hands off my girlfriend, you disgusting bug!" Otoya shouted.

A firearm noise was heard. Someone had shot.

And the award for the teacher of year go to...Kamikuro Reiko-sensei! Such a good teacher.

So, who shot who? Probably not Shiena. Maybe it was Midori, who was hiding under the bed!

More seriously, even if I know how I want to finish this story, what kind of ending would you prefer? An happy one? A bad ending? Or maybe something neutral?

Oh and, first I didn't want to kill the Mikage Twins, but since so much people thought they were the culprits, I decided to kill them, just to troll you. I'm such a good person :)
