He leaves it outside, but when he checks on it some time later, he finds that it has disappeared. When he sees the fish, he is disgusted but is able to put it into a bag.

He hears the fish from behind a table and attempts to kill it by pushing the table against the wall with his strength (the fish is already dead, though - only the walking machine allows it movement). Tadashi, upon returning to the house, smells the fumes and finds Kaori unconscious. She eventually sees a fish attached to a metallic machine that affords it four legs (this is known as the “walking machine”) and faints after seeing it. While he is gone, Kaori goes to take a shower and smells the stench. Tadashi tells Kaori to make herself at home and proceeds to leave the house to get some air fresheners. He eventually found her fixated on something in the darkness Kaori was so unnerved at what she had seen that she went back to their rented house (which their uncle let them borrow) without resistance. She shows her will by leaving, causing a concerned and remorseful Tadashi to follow. They argue, and she says that if he continues acting that way, they might as well end the vacation early on.

Upon going back to their house, Kaori continued to mention that she could smell the fumes, causing Tadashi to become angry. Confused at what he had seen, he became only more concerned when Kaori complained of a terrible smell. Tadashi, while scuba diving, barely avoided the sharks, and saw something moving at a high speed. A young man, Tadashi, was staying there with his girlfriend Kaori to enjoy their vacation.
