2 years ago, Manjiro, Ken, Keisuke, Takashi, Pah-chin, and Kazutora had their gang uniforms made and they all took a trip to Kanagawa on their motorcycles. Meanwhile, their commander Manjiro rode his moped, Street Hawk. They get surrounded by a local biker gang, but Manjiro shows no fear and tells the older gang members that he'll kill them if they lay a finger on his Street Hawk.

Back in present day, Ken tells Takemichi that Kazutora ends up killing Keisuke at the Bloody Halloween, the fight against Toman and Valhalla, and Manjiro ends up killing Kazutora. Because of that, Manjiro falls into darkness, and Toman is taken over by Valhalla, which leads to the evil organization that it currently is now, led by Kisaki. Takemichi goes back to the past with a new mission: to protect Keisuke so that this tragedy doesn't happen.
