Staff Animation Assassination Classroom revealed

Assassination Classroom (Ansatsu Kyoshitsu) is written and drawn by Yusei Matsui manga. It is pre-published in Weekly Shonen Jump magazine editor Shueisha since July 2012 and has been compiled in nine volumes in May 2014.
An animated series based on the manga is scheduled to premiere on Fuji TV in 2015. A live action film will also be created.

The Earth is threatened by a powerful creature who destroyed 70% of the Moon with its power, rendering into the shape of a crescent moon forever. The creature claims that within a year, Earth will also be destroyed by him, but he offers mankind a chance to avert this fate. In class 3-E at Kunugigaoka Junior High School, he starts working as a homeroom teacher where he teaches his students not only regular subjects, but the ways of assassination.
The Japanese government promises a reward of ¥10 billion (i.e. 100 million USD) to whoever among the students succeeds to kill their teacher, whom they have named "Korosensei". However, this has proven to be an almost impossible task, as he has several inhuman abilities at his disposal, including the capacity of moving at Mach 20.
