[Inamitsu Shinji] Seishokuki Volume 17 [AK Devil]

A voluptuous, sharp-toothed demon girl with curling tendrils and long claws anchors a school-horror story following a short-haired high-school boy as he takes a phone call about a dangerous principal, his mother, and a plan going badly wrong. The monochrome pages move through crowded classrooms, a girl taking the initiative among other students, and a shirtless boy crouched in a tiled corridor, warning someone not to touch her as an unwanted hand closes in. A final group of uniformed figures, a looming sword, and a grotesque appendage turn the suggestive school encounters into a promise of supernatural danger.
