Gakuen Shinshoku: XX of the Dead is a high-quality tentacle hentai OVA adaptation of the classic PC game "XX of the Dead" by SYOKU. Set in a school under sudden invasion by bizarre, otherworldly monsters, the story fuses panic horror with intense eroticism.

The grotesque creatures gradually corrupt the academy, attacking students and staff. Those captured are either devoured and turned into zombies or parasitized, becoming hosts for writhing tentacles that force victims into waves of uncontrollable ecstasy. As the infection spreads, survivors witness their friends and loved ones succumbing one by one, their minds breaking under relentless pleasure.

The anime spotlights three key heroines: a devoted bro-con little sister, a soft-spoken gentle beauty, and a lewd female teacher. All three endure fierce tentacle violations filled with domination, creampies, and mind-melting orgasms. The upper volume focuses on the initial outbreak and first major assaults, while the lower volume escalates the chaos as twisted desires manifest and the school transforms into a lust-filled nightmare.

With excellent animation, high production values for its price, and a perfect mix of survival horror and non-stop tentacle action, this is a must-watch for fans of classic school invasion and monster girl/tentacle erotica. The heroines' fall from resistance to total submission delivers powerful, unforgettable scenes.

Based on the erotic game by Syoku.
