High school student Kusakabe Makoto has to work all day to raise money for the treatment of his younger sister, who suffers from a serious illness. The father is unemployed, the mother ran away, leaving the children, bullying at work ... Despite all this, he does not lose hope and continues to live for her sister. But having learned that she did not have long, Makoto falls into despair. Fear of the unknown causes him to take a different look at the value of human life.

A group of high school students were spending their peaceful days freely until they have been chosen as the participants of the game where everyone is being hypnotized until they commit suicide. No one is safe from a sudden death, so what will they do to avoid their fates?

Is there someone whom you desperately wish to see dead? If you want your enemies and rivals eliminated, free-of-charge and with no possibility of the crime being traced back to you, all you need to do is leave a message for "Usobuki Tadashi" in a certain telephone booth at a certain park.

Soon afterwards, a black-suited man with cold, crimson eyes will meet with you and confirm the target. He cannot be prosecuted, for he kills through the power of suggestion and the clever arrangement of events. He will accept any request: regardless of whether the target is saint or sinner, and no matter how foolish, cruel or misguided the client... All with a mocking smile on his face that belies his quiet amusement in the face of humankind's never-ending folly.
