Rock and Revy accompany Balalaika to Japan, where they enact -- then endanger -- an assignment to take out one yakuza gang at the behest of another.

Feuding breaks out between Balalaika and the Washimine gang, and Rock makes a shocking discovery about Yukio, the girl he met at the festival.

Yukio is abducted on the day she takes control of the Washimine Group, and Rock pleads with Ginji to let him and Revy help rescue her.
