After Peeps bestows Sasaki with magic and the ability to cross worlds, the two decide to export household items for profit in pursuit of a leisurely lifestyle. But when Sasaki’s new magic gets him mixed up in a whole other kind of supernatural struggle back in Japan, will it destroy his chances of realizing the relaxing life of his dreams?
