Shinnosuke and his buddies from the 'Kasukabe Defence Force' embark on a week-long sojourn at the prestigious 'Tenkatōitsu Kasukabe Private Academy,' affectionately known as 'Tenkazu.' Here, the school is governed by the cutting-edge AI, 'Otsmun,' which assigns each student an initial 1000-point badge, subject to fluctuations based on their conduct and academic achievements. Amidst the tranquil setting, chaos ensues when Kazama becomes a target of an attack, resulting in a peculiar reduction in his intellect and enigmatic bite marks on an unexpected location. In response, the Kasukabe Defense Force teams up with the unconventional ex-athlete and former student council president, Chishio Atsuki, to assemble a squad of sleuths aimed at unraveling the perplexing enigma.
