Yamazaki Ichimon — Unification of Japan: The Movie (or "The Y-Team")

Himuro is arrested on suspicion of assault. To prove his innocence, members of the Yamazaki Ichimon scramble to locate Ito—the older man Himuro once helped (Hiroo Otaka), who could serve as a key witness. Meanwhile, Tamura visits a certain hospital, where he is suddenly attacked by a man.
