Mina, featured in the "Beast City" OAV series, is a 19-year-old Beast Hunter balancing her duties with college life. When a new woman arrives at her college, outwardly the daughter of a wealthy industrialist but secretly concealing a malevolent entity, Mina is drawn into conflict. This entity preys on men, seducing and destroying them. Mina intervenes to protect a targeted friend. The story unfolds amidst Tokyo's violent clashes between humans and demonic beasts, entities that seek to seduce and enslave women. The three-episode OAV, released between 1996 and 1998, explores themes including tentacles and explicit content, with its third episode remaining unreleased on North American home video.
