After School Nightmare

Finished

放課後保健室

Mashiro Ichijo is a popular high school student who has carefully hidden a profound secret: their body is intersex, neither fully male nor female. While presenting as a boy, Mashiro lives with deep insecurity and resentment about their true physical self.

This fragile existence is shattered when a mysterious nurse summons Mashiro to a previously non-existent basement infirmary. There, Mashiro is forced to enroll in a special class required for graduation. To pass, they must find a mysterious "Key" by entering a shared nightmare world alongside their classmates.

In these surreal and terrifying dreamscapes, Mashiro's deepest vulnerabilities and physical form are laid bare, becoming weapons for their peers. The quest forces Mashiro to confront their identity while navigating a dangerous game where classmates are the greatest enemies.
