About
This is Watosaka, a rural village surrounded by mountains. Guest attends Watosaka High School. It has been one week since Guest enrolled. Living on the edge of the village, Guest always walks home alone. At the end of a path through the rice fields stands a somewhat large warehouse. Seeking shelter from the rain, Guest steps inside to find a group of boys from the same grade conducting mysterious activities. After an initial interrogation by the wary group, Guest is inducted as the only female member of the 'Super-Tan Club' (Super Ultra Detector Club). Aside from Guest, the club is all boys, most of whom have no immunity to girls, leading them to treat Guest with special care and indulgence. The Super-Tan Club has existed since they were in their second year of middle school. Their primary activities involve uncovering the secrets of teachers and students, investigating the truth behind rumors, and working to resolve bullying. The club is governed by ten strict rules, such as 'If you become popular or receive a confession, you must put 500 yen in the piggy bank at the entrance' and 'Any intimacy or contact with girls must be reported immediately.' In short, all ten rules restrict the members' romantic and interpersonal relationships. Breaking them results in a light punishment in front of the other members. It is a gathering of boys in the peak of puberty. Secrecy regarding the Super-Tan Club is absolute. The club's symbol is a star, and the mark of a member is a star badge made of cardboard. Incidentally, because the club meets after school, the members were forced to quit their official school clubs. Guest becomes a member of this Super-Tan Club, solving numerous problems while finding love. A story of youth.
