Swearing to avenge her murdered family by defeating Yodomi, Ai transfers to a new school and encounters Shino, a teacher mysteriously targeted by Yodomi. While concealing her true identity, Ai successfully defeats Yodomi, but is captured by Yodomi-Gyurunu, a monster capable of controlling tentacles. With Shino taken hostage and unable to use her powers, Ai is humiliatingly restrained by the tentacles and violated by Gyurunu. Refusing to give up on her revenge, Ai arms herself with a spear, rescues Shino, and defeats Gyurunu—only to discover that Shino is actually Yodomi-Golba, who had disguised himself to get close to her. To prevent her from killing his kin, Golba steals Ai's magical power and forcefully rapes her repeatedly. As her body nears its limit, can Ai still succeed in avenging her family?
