I usually like the girl Ruri everywhere. However, she "hit man" was a special man. Innocent people in the world do people become victims of wanton cruelty offenders in selfishness, and anger reached a peak at her face with evil only as a weapon in his fist. Incessantly from the hearts of people born "evil" is something. People judge the sins of the law, you can save the people. Wanton violence "blow" that can silence the evil of violence in day become a country ruled by law is also a criminal Ruri. Exactly "justice" is what? Ruri depicted the figure of the struggle to fight but the fate of mankind as a blow.

Anzu Natsuno, an ordinary student at an all-girls high school, is walking in the hallway when she is attracted by a mysterious melody coming from the auditorium. There, she finds her classmate Kana singing and, much to Anzu's shock, commits suicide right before her. A few days later, Anzu is approached by magazine columnist Riku Nagasei, who is investigating an urban legend about the Densen Uta, or the infectious song, that turns whoever sings it suicidal. In order to verify the urban legend, Riku convinces Anzu and her friends to sing the song, which they reluctantly agree. Soon after, one by one, the girls begin to kill themselves.
