[Shiroi Tentoumushi (Ta ta)] Gob Rinkan Gakkou

Amakawa, a strict class rep whose curvy figure keeps classmates whispering, patrols the halls of a school run by the imposing third-year teacher Moriguchi Kyoko—until a sprinting student's head bursts apart and the screams of an unseen massacre start bleeding into an otherwise ordinary day. As goblins armed with knives overrun the corridors, a long-haired senpai holds the line with a wooden sword, ordering her friend Rin to run for a doctor while a blade presses against her throat and steals her voice. What unfolds is a schoolwide hunt, 105 pages of the creatures stripping uniforms away and overwhelming the big-breasted students and staff one by one.
