Tokyo Revengers

 

Real Shock! Takemichi Hanagaki is a real loser while in his 20s. And he was a loser in his teens as well. But lucky for him, he gets to time travel. He uses this time travel power to continue being a loser in the past. Will he overcome his natural lame-ness and become a Tokyo Revenger against the gang that killed his ex girlfriend? Or will she just keep getting killed in increasingly violent and over-the-top ways?
