[Fan no Hitori] Taimabu S4 Gesuidou Hen 3 [biribiri]

An aggressive squad of schoolgirls in tight uniforms storms the sewers, confronting a grotesque mutant that threatens their club's leader, while a masked, skeletal‑smiling warrior brandishes a blade with reckless confidence. The tension spikes as the fighters grapple with a dangerous, spontaneous mutation whose movements could expose them to lethal retaliation, and a mysterious exorcist joins the fray, promising both salvation and sin. The story weaves fierce combat, sensual struggle, and supernatural intrigue into a relentless, erotic battle for dominance in the underground.
