As Hideo’s disappearance is unofficially shrugged off by the police, Kimi tries to ease tensions between the tenants and Mr. Koshide‘s interns with a shaved ice party. But as preparations are made, the senior tenants decide to investigate the strange piles of dead fish on the property and assume one of the interns is responsible, only for the mystery to deepen as one of them decides to stand guard. The party commences with Kentaro Yoshii realizing something is wrong when the shaved ice syrup tastes strange, finding his follow tenant’s apartment growing moss while the syrup is revealed to contaminated with a dog’s severed head.
