At the boarding house, the men who were gathered from the Yakuza were forced to do forced labor. One day, Suzu came to deliver a boxed lunch from a cheap delivery store that delivers lunches once every three days, not knowing anything about the place. The workers, who had been starved of women, pinned her down and devoured her. Since then, they have been slowly eating away at Suzu's Kokoro, corrupting her into a sex toy every day. In the midst of all this, the Yakuza who runs the place also appears... and the tragedy continues with a shocking pregnancy ending.
