Ichi has managed to get himself stuck with "obligation for a night's lodging" & is going along with a small band of annoying gangsters to help their oyabun (boss) against a rival gang. With Ichi at their side, it's pretty much guaranteed that the rivals will soon be dead, unless they run away. Ichi hates to be used in this manner, but he is a stickler for the yakuza code, & he did accept food & lodging, so he has no choice.
