when the bladder's blood bleeds on a swinging train. (reprinted special price version)

Manyuri Kurashina is a judicial trainee working at a law firm. She has an older sister, Majumi, who is already married. Many events occurred that seemed to be lacking in some of his memories. Manyuri, who was on the train at one time, is caught in a state of being jealous of someone else's "one more self" and he invites him to join Honbashi, the representative of the law firm. It is completely different from Manyuri, who was thought to be a person. Majumi, who knew his sister's turmoil, revived the memories that he had been holding slightly. There was a twin sister who had never been alive in this world.
