Katte ni Kaizou

Seventeen-year-old Katsu Kaizou is an exceptionally gullible high school student with an unwavering belief in science fiction, aliens, ghosts, UFOs, and conspiracies. He is convinced that every event unfolding around him is part of an extraterrestrial scheme to conquer Earth. The series consists of largely self-contained episodes, each one utterly bizarre. After joining his school's science club, Kaizou makes new friends and soon finds himself encountering a bewildering array of strange phenomena—including log people, lethal sushi, so-called "pee-blades," terrifying infections, robot invasions, ghosts, living dolls, and much more.
