At the moment of helplessness, Aloha (Takeru Sato), who called himself a devil and looked exactly like the postman, appeared in front of the postman. He claimed to have prepared a chance for the postman to extend his life, but in the devil's law, there must be gains and losses. Assuming that the postman's life is extended by one day, something in the world will disappear. The half-believing postman accepted Aloha's suggestion, and he eliminated the phone, movie and clock one after another. For example, the disappearance of the phone freed the head-down tribe from the virtual world, giving the postman a faint sense of accomplishment. However, the seemingly insignificant disappearance also took away the people and things he valued most. For example, his first love girlfriend (Aoi Miyazaki) and his friend Blockbuster (Gaku Hamada) who became friends because of the movie. In the end, even the postman's beloved cat Cabbage faced the fate of disappearing...
