Synopsis
An uncharted island exists somewhere off the coast of a prefecture in Japan.
The only way to reach it is by boat from the nearest port.
Protagonist Hayabusa Hayamizu and his colleagues are heading to this island.
Their mission: investigate the cause of an alarm emanating from a corporate research facility located there.
It was supposed to be a false alarm…
But their expectations are shattered when disaster strikes.
The slime mold being studied at the facility goes haywire, transforming not only the researchers working there, but also his colleagues into grotesque monsters.
Hayabusa searches for an exit with his sister Tomoka, who lived at the facility, as they desperately try to escape.
During their flight, both siblings are violated as the monsters release their essence deep within their bodies.
The sisters writhe in agony, their mouths, vaginas, and anuses penetrated by massive tentacles in gang rape.
What fate awaits these two…?
