Valhalla Arc
Two weeks have passed since Bloody Halloween. Tokyo Manji Gang Second Division member Takemichi Hanagaki and Vice President Ken Ryuguji visit former Valhalla leader Kazutora Hanemiya at the Tokyo Juvenile Detention Center. Inside a private meeting room, Kazutora informs the two that he was told by the judge to expect a ten-year sentence. He wallows in guilt as he heavily disagrees with the duration of his retribution, but promises that he will no longer run away from his personal problems and will get proper rehabilitation this time around. Draken tells him not to kill himself to make up for his involvement in Keisuke Baji's death, but Kazutora declines his advice. However, Draken informs him that Manjiro Sano has already forgiven him despite the trouble he caused in Bloody Halloween, and Kazutora erupts into tears.

As Takemichi time leaps to the present and witnesses a close confrontation with Tetta Kisaki, Kazutora rescues him from danger and accosts him with the current Toman's condition. Kazutora admits that he wanted to save Chifuyu Matsuno rather than him, and recalls the day Chifuyu picked him up from the detention center after a long time of not seeing each other. Chifuyu explained how Toman has become an evil organization and instigated a plan with Kazutora to bring back the original gang they once knew in middle school, forming an alliance with each other in taking down Kisaki.

Bonten Arc
After Takemichi visits XJ Land, he meets Kazutora outside the pet shop who expresses his thoughts about Mikey's condition. He tells him that time seemed to stop while he was in the detention center and compares his experience to the tale of Urashima Taro, where a fisherman is taken to a Dragon Palace beneath the sea as a reward of rescuing a turtle and seemingly spends several days there, when in fact, he has been gone in the real world for over a hundred years.
