A high school boy accidentally summons an alien ghost and decides a pet is fine, except the pet moves into his body instead. The show's real laugh is watching him negotiate living space with something that doesn't understand doors, privacy, or why humans need sleep. Every episode is two minutes of pure absurdist roommate comedy trapped inside one confused teenager.
Takashi's summer takes an unexpected turn when a bizarre accident leaves him sharing his body with an alien spirit. Rather than panicking, he decides to call his new roommate Uchurei and treat it like a pet project. The problem: Uchurei has other ideas about their living arrangement, and possession isn't quite the one-way street Takashi imagined. What follows is a constant negotiation between a teenager trying to maintain his normal high school life and an otherworldly entity with zero understanding of human customs or personal boundaries. Takashi can't exactly tell his friends why he's acting strange, and Uchurei can't stop causing chaos every time it takes control. Their dynamic swings wildly from comedic to genuinely awkward, with each episode finding new ways to complicate what should have been a simple supernatural situation. It's goofy sci-fi comedy that doesn't take itself seriously, anchored by the bizarre chemistry between an exasperated human and an alien that seems to operate on pure, chaotic logic. Perfect for viewers who want their summer anime weird and lighthearted.
