Katsuhira Agata appears to be an ordinary high school sophomore in Sugomori City, yet beneath his calm exterior lies a profound absence — the inability to feel physical pain, a consequence of a mysterious childhood experiment that also dulled his emotional responses. As a participant in the Kiznaiver project, he shares wounds with his fellow members, and through this collective suffering, long-buried memories resurface and his dormant heart slowly reawakens, guiding him toward genuine human connection.
