Tokyo Revengers

synopsis

Takemichi Hanagaki leads a dead-end life in a run-down apartment while working part-time at a job where he is treated poorly. Then one day, he learns that a girl he used to date, Hinata Tachibana, and her brother, Naoto, have been murdered by the Kanto area's most villainous hoodlums, Tokyo Manji. The next day, Takemichi is standing on a train platform when he is suddenly pushed onto the tracks. But instead of dying, Takemichi is transported ten years into the past where he is reunited with Hinata's younger brother, whom he warns of events to come. Hinata still doesn't survive, but Naoto does, becoming a police detective. Returning to the present day, Takemichi recruits Naoto's help in returning to the past to crush Tokyo Manji and save his Hinata's life once and for all.
