Mir-cruel and confusing place for Maumi. At the age of thirteen, he lost his parents in a car accident. Unable to cope with overwhelming sadness, hatred and anger, I just wanted me to completely stop feeling. Then, five years later, her sister becomes the first goal of an incredibly strange incident. The victims of this incident lose part of the body without losing blood after receiving a text message in which the specific part of the body is simply indicated. Messages seem to come from the former boyfriend sisters Mumy Canned, but he claims not to blame. Maumi works with him to reveal the case, but is he really innocent? Or is the crime somehow connected with the suicide Canned? S promised many years ago? Or is it connected with an unfinished artificial intelligence program, which I wrote, which may have been released? And even if this incident is resolved, can Maumi ever be emotionally healed among the useless cruelty of the world?
