As she grieves over the random punishment, the Slit-Mouthed Woman presses her, asking if she looks pretty. Shizuka flees to the empty school after classes.

Kamui receives a message from Shizuka that she's going to hang out with her best friend Kyoko, and upon seeing the attached photo, he senses something. Will Shizuka be able to hide Kamui's exorcism from Kyoko?!
