Hazumi witnesses the power of butt swordplay and hires Hiroshinosuke as her bodyguard. The Noharas begin traveling to Mt. Fuji Prefecture with her, but encounter trouble when they try to cross a river on a boat.

It becomes apparent that Hazumi's life is in danger. Black Funkycow is using his men to try and kill her. The next assassin is a sniper who has never missed his target before.

Hiroshinosuke sees a wanted poster for Hazumi putting a price on her head. He and his wife Omisa become blinded by greed from the prospect of a zillion-dollar reward. They try to get to Mt. Fuji Prefecture as soon as they can.

Right before they arrive in Mt. Fuji Prefecture, a big gorilla appears before them along a mountain pass. It was also sent to capture Hazumi. Black Funkycow apparently works for another man who wants to eliminate her.
