Tokyo Revengers

In the anime Tokyo Revengers, Takemichi Hanagaki is a directionless adult whose life hits rock bottom upon learning his childhood girlfriend, Hinata Tachibana, was killed by the notorious Tokyo Manji Gang. His despair reaches its peak when he is pushed onto a train track, but instead of dying, he awakens 12 years in the past, back in his middle school days.

Armed with knowledge of the future, Takemichi is presented with a single, desperate goal: change fate itself. He must navigate the brutal world of delinquent gangs to prevent the tragic future that awaits Hinata and himself. This journey forces the cowardly Takemichi to confront his past, forge powerful bonds, and find the courage to fight for a second chance at life.

The anime masterfully blends intense gang warfare with deep emotional stakes, exploring themes of regret, redemption, and the profound impact one person can have on the future.
