Read Manga Youkai Kyoushitsu online in English. Also known as Dissolving Classroom, Yōkai Kyōshitsu, Youkai Kyoushitsu, and 溶解教室.

From horror master Junji Ito comes a disturbing collection centered on Yuuma Azawa, a polite high school boy whose endless apologies feel wrong from the moment he opens his mouth. Wherever Yuuma appears, his eerie younger sister Chizumi is never far behind, and the ordinary spaces around them, classrooms, apartments, streets, begin to rot into scenes of grotesque terror.

Yuuma’s obsession with the devil turns simple guilt into something far more horrifying, while Chizumi’s appetite for chaos pushes each encounter closer to madness. The manga builds its fear through strange social discomfort, body horror, and the sick feeling that kindness, shame, and apology can all be twisted into weapons.

This series may appeal to readers who enjoy supernatural horror, grotesque psychological tension, and darkly surreal short-story manga.
