Summary
Takemichi Hanagaki, an adult and a failure, discovers the death of Hinata Tachibana and is transported 12 years into the past; he decides to save Hinata by changing events from his youth. He infiltrates the Tokyo Manji Gang (Toman) during high school, earns the trust of members, and starts to interfere in decisions to prevent future deaths. Conflicts arise with rival gangs and decisive episodes, including the arc known as Bloody Halloween, which alters the fate of several members and exposes manipulators behind the violence. Takemichi performs multiple time jumps, adjusting actions in different timelines to minimize losses and confront the architects of the tragedies. Large-scale conflicts involve rival organizations like Valhalla and Tenjiku, transforming street disputes into organized confrontations between factions. Throughout the series, Takemichi deals with the consequences of each new timeline: deaths prevented in one moment may create new risks in another, requiring sacrifices and alliances to try to restore a future in which Hinata survives.
