Revenge on the Shinjou sisters... Makoto, who has the hypno device in hand, traps the "evil childhood friend sisters". Hinana puts on the choker handed over by Serina without realizing that it is the hypno device. When the hypno device is activated, she utters words that are the opposite of her own will, and at the same time, her body reacts like a puppet. Makoto gives orders as if enjoying the change and manipulates her as she pleases. Just then, Serina appears, and the hypno device button is pressed, Serina is also subdued in an instant. Hinana and Serina, who have opened a new door, have come to know the pleasure of falling into the body of sex.
