Tokyo Revengers

Hanagaki Takemichi is a worthless part-time worker who's down in the dumps; one day, he gets pushed off the station platform onto the railroad tracks with a train coming right for him, but the next thing he knows, he's reliving his life from 12 years ago.

Takemichi returns to the present after shaking hands with Naoto and is reunited with Naoto, who is now a police officer; Naoto asks Takemichi to go back in time and prevent the two leaders of the Tokyo Manji Gang from meeting so that they can save Hinata.

To protect his friend Yamamoto Takuya, who's a bit frail, Takemichi challenges Kiyomasa to a fight; despite being beaten to a pulp, Takemichi doesn't back down, which starts to make Kiyomasa panic.

Takemichi gets to enjoy some happy times with Hinata during their middle school days until he's suddenly sent back to the present; after seeing how Mikey was, he can't imagine that it was Mikey that turned the Tokyo Manji Gang into an evil organization.

Naoto finds out that 12 years ago, the Tokyo Manji Gang had split into the Mikey Faction and the Draken Faction and due to one of their disputes, Draken ends up dying; however, Takemichi refuses to believe that Mikey and Draken would ever fight.

As Pah-chin's friend was attacked by Moebius, the Tokyo Manji Gang decides to fight Moebius; according to Naoto, Draken doesn't die because of the conflict with Moebius, but rather, an internal conflict between the Tokyo Manji Gang.
