A loser gets one chance to rewrite his worst choice, but time travel here has a cost and no safety net. Every decision sticks. Every punch matters because he can't reload, he can only go back 12 years, fix one thing, and watch the consequences ripple forward in ways he didn't expect. Takemichi's desperation to save Hinata is the only thing that makes him watchable, because the show knows he's a coward and a failure, and that's exactly why you keep going with him.
Takemichi Hanagaki is a directionless thirty-year-old living paycheck to paycheck, haunted by the news that Hinata, his first love from middle school, has been murdered by Tokyo Manji Gang. A tragic accident at the train station sends him spiraling through time itself, landing him back twelve years in the past when he was still a kid with everything ahead of him. Desperate to rewrite his future, Takemichi throws himself into Tokyo's gang underworld. He needs to prevent Hinata's death, which means confronting the ruthless organization responsible and the twisted loyalties that hold it together. But changing the past proves more dangerous than he expected. Every decision ripples forward, allies become enemies, and the closer he gets to saving her, the further he seems to push her away. Caught between two timelines, Takemichi must navigate brutal street fights, impossible choices, and the question of whether anyone can truly escape their fate. Time travel becomes his weapon and his curse as he fights for a second chance.
