Kamiyama-san no Kamibukuro no Naka ni wa

A high school student named Namito Kominato meets Samidare Kamiyama, a shy girl with social anxiety who wears a paper bag over her head. Despite her difficulty communicating, they become friends. They are joined by the enthusiastic class representative, and together they start a club to help Kamiyama engage with school life. The club requires four members, and they find a potential fourth who communicates only with a magical girl cardboard cutout. The group aims to create a supportive environment for students who struggle socially.
