Tokyo Revengers 1x53

Twelve years later, the criminal underworld is ruled by Bonten, an organization far more vicious than the old Tokyo Manji Gang. Takemichi is stunned to learn that Bonten is led by someone from his former life. He wants to go back in time, but the power he once relied on is now out of reach. With no way back, Takemichi meets his friends to open the time capsule they buried 12 years ago.
