Crayon Shin-chan Movie 29: Nazo Meki! Hana no Tenkasu Gakuen

Shinnosuke and the Kasukabe Defense Force are invited to spend a week at the elite Tenkasu Academy, a boarding school where the AI Otsmun constantly evaluates every student's behavior and ability. The strict point system clashes immediately with Shin-chan's chaotic personality, but the visit becomes far stranger after Kazama is attacked and suddenly loses much of his intelligence.

With suspicious bite marks providing their only clue, Shin-chan and his friends join former student council president Chishio Atsuki to investigate. What begins as a school mystery draws them through the academy's hidden corners as they search for the truth behind the attacks.
