Shin Seiki Inma Seiden 4

Senna and Mao find themselves ensnared in a dark struggle between the Kameyama and Otori families for dominance at Otori Academy. As sinister forces unleash terror—tentacles violating Senna and the masked assailant cornering Mao—their world spirals into chaos. Amidst the brutality, Hitomi intervenes, sparking fleeting hope. Yet, as desire and fear intertwine, the women face escalating horrors, their bodies and minds entangled in a twisted game of power, pleasure, and unspeakable torment. The nightmare has only begun.
