Hanagaki Takemichi is a worthless part-time worker who's down in the dumps. Takemichi is shocked by news that his ex-girlfriend was killed, but goes about his daily life when he is suddenly pushed onto the railroad tracks.

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.

In order 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. Then, the commander and vice commander of the Tokyo Manji Gang, Sano Manjiro, AKA Mikey, and Ryuguji Ken, AKA Draken show up.

Takemichi gets to enjoy some happy times with Hinata back during their middle school days but then he is suddenly sent back to the present.

Takemichi renews his determination as he goes back in time yet again, but when he opens his eyes, he finds a girl he doesn't know wearing just her underwear looking down on him.
