I haven't seen him for a very long time. Too long. He has become a teacher, but me, well I'm off the radar. I've become the assassin I was ment go be. I was never going to be a politician! Never! Not in a million years. I'm fine with this job. But why did he have to be the thing I despise the most. Why did Nagisa have to be a teacher. I've only had one good teacher in my whole life and he was to be murdered, by the students. I'm a bit scared from that. I was already scared but now I'm just a shell. a broken puzzle. Maybe, just maybe, he can put the pieces back together. Time to see my poisonous friend again. I'm coming back to you, Nagisa.

Nagisa's students decide that spying on their teacher is the only way they'll find out more about his relationship with the mysterious red-head who has been giving the teacher rides to class.

Nagisa has never been so nervous about anything...in probably his whole life. His mother treated him like a girl in his past, forced him to wear dresses and grow out his hair. It's only natural that he be so anxious about what Karma will think of his new haircut. (KarmaXNagisa)

(It's KarmaXNagisa, but that's not the main focus) Nagisa is sick. He was rushed to the hospital one night after coughing up blood, and diagnosed with a deadly disease. He has to decide whether he should open up to his friends, or keep quiet and suffer alone knowing that he is a walking corpse.

Nagisa used to be the top bad boy of the school, until his Dad died. His Dad was the nicest, most generous person, and Nagisa always looked up to him. Karma hated Nagisa. He should be the top bad boy, until suddenly one day he was. Confused by how he had such reputation all the sudden he watched Nagisa in class and saw a tear roll down his face. He decided to give up his hatred for him and let him be. Then both of them where placed in the End Class.
