Rakuen Shinshoku: Island of the dead

Synopsis

Based on the erotic game by Syoku.

During a party at a luxury resort hotel on an isolated island in the middle of the ocean, screams suddenly erupted. What appeared before their eyes were monsters parasitized by tentacles. Confronted by these creatures, the humans took action, some hid themselves, others fought, and repeated actions to escape from the threat. But is there any hope for them?
