Assassin name : Childish Devil (Karma x OC)

Kunugigaoka's school

Tokoyami's POV :

I wake up to the sound of my alarm clock, it was 6:30 in the morning and today was supposed to be my first day at the most prestigious school Kunugigaoka. I quickly get up and prepared myself and before leaving my room to go downstairs I glanced at the poster of my deceased mother when she was an idol. My father was waiting for me and he looked pretty calm.

'The day's only starting Tokoyami.'

Once I was in front of my father I greet him. "Good morning, Father." I bowed to him, he only nodded and patted me a little on the head. I stiff slightly but he didn't notice.

"I will accompany you today to speak with the chairman. You must remember him, he is a friend Asano Gakuho." My father told me.

I nodded before answering "Yes, I remember. He has a son if I'm not mistaken so does that mean that we'll be in the same class ?"

"Since you did a full mark on the test you're in the A class, the same as Asano-kun."

"I see". 'Good to know.'

We went in the car, the ride for the school was quiet and I thought it was going to be like that until our arrival but my father spoke. "You can act whatever you want with Asano-kun but don't forget to be in the good sides of the others students, understood ?"

His tone implied that I should obey. "Yes father."

He nodded and the silence came back but we arrived a short time after, I caught a glimpse of strawberry blonde hair the second I stepped out of the car. I went to him and tapped him on the shoulder. "Long time no see Gakushuu-senpai."

The strawberry blonde male turned to me and slightly smiled. "Yeah, long time no see Tokoyami-kun. My father told me that we were going to be in the same class, it's good to hear." I only nodded in response and my father was beside us a second after.

"Hello to you Asano-kun. I hope you'll take good care of my son since he is the youngest in your year. If you'll excuse me I have to talk with you father." And with that he went his way, I heard Gakushuu sigh when he left. "I don't understand how you can live with this man Tokoyami."

"He's still my father. Even if... he changed" I trailed.

On our way I noticed a blue haired boy going farther then the main campus, at first I thought it was a girl because of his feminine look but he was wearing the boy's uniform so it was obvious. I stopped and Gakushuu stopped too.

"Nee Gakushuu-senpai, where is this guy going and who is he ?" I asked while pointing to the androgynous boy with pigtails. He looked at the direction I was pointing before looking at me with a scowl. "He is going to the mountain because the batiment for his class is there. He is a student from Class E. The End Class, you get there if you have bad grades or bad behavior."

I just nodded and replied with a monotone "I see."

Gakushuu continued to look at me for a moment before chluking "You're still as emotionless and monotone as ever."

I shrugged "If you say so..."

All day long I followed Gakushuu everywhere and talked when people came my way, after some time 4 guys came up to me and Gakushuu, I grimaced a bit when I saw their head. 'I never saw people THIS ugly until today !' Fortunately for me only my strawberry blonde childhood-friend noticed my grimace but I quickly regained my composure and I remarked that one of them looked alright. 'Thanks God.'

"Hello Asano-kun, who is this boy with you ?" The good-looking boy asked. He has brown hair that is fashioned into a kariage (clipped) hairstyle and dark, almond-shaped eyes.

"This is my childhood-friend Rakuen Tokoyami, Tokoyami-kun this is Sakakibara Ren.  He is the Student Council secretary."

'Now it begins.' "Hello Sakakibara-senpai, it's a pleasure to meet you !" I exclaimed in a cheerful way that cause Gakushuu to look at me with slightly widened eyes.

"Nice to meet you too Rakuen-kun. And why did you call me senpai ?" Sakakibara asked.

"Because I'm one year younger than any other students of third year. I'm 14 after all." I answered while keeping my cheerful demeanour.

"YOU'RE 14 !?" All the students of the classroom exclaimed.

"Yep."

"You must be a true genius Rakuen-kun." Said Sakakibara while smiling at me.

"You can call me Tokoyami Sakakibara-senpai !" I said with a big grin.

"As you wish Tokoyami-kun."

And the day went on like that, everyone acknowledged me as a genius because I was the youngest and it got me a lot of respect from all the students of the main campus. After school I went  back home, but I wasn't really expecting to see my father waiting for me with his arms crossed on his chest. 'What does he have to tell me now ? It's only my first day of school and something is already going to change.'

3rd person's POV :

Tokoyami put off his shoes before walking in front of his father. "What is it Father ?" "We have to talk. Come with me."

They went to the living-room and the both of them sat on a couch that were facing each other.

"I learned something very interesting when I talked with Gakuho. Do you remember what happened to the moon ?" 

"70% of the moon got destroyed." He replied emotionless.

"That's right. Well, Gakuho told me that the cause of this was teaching Class E, and the cause is this."

The adult give his son a sheet of paper with a picture of a yellow octupus whose face has green stripes. Tokoyami looked at it with a blank face before looking at his father. "And why is this octopus teaching the E Class ?" He questioned.

"We don't know but what is interesting is that the class have to kill him before March or else this thing is going to blow up the moon and the reward is 10 billion of yen. Since you are an assassin, you'll be transferring in the E Class and you, the Childish Devil is going to kill him so I'll  get the money. Is that clear."

His tone clearly didn't let any choice to the boy so he only said "When did I start ?"

"Tomorrow."

And this is how Rakuen Tokoyami got into Class E with the mission of assassinate his new teaher.
