Saya struggles to keep the Furukimono from killing more students as she becomes tormented with flashbacks. Although she eventually manages to kill the Furukimono, all of her classmates besides Itsuki had been killed. After lamenting to the dog, who poses more questions about her nature, and being visited by Shinichirō, Saya comes to the realisation that only her class had been called to school that day. As Shinichirō's attempt to confess to Saya is put off by the arrival of Tadayoshi, Saya questions why she doesn't know her mother's name.

Kanako, Nene and Nono, along with Shinichirō who also appears, reveal themselves to be part of a 'main cast', playing roles for the purpose of making Saya remember who she is in order to be rewarded with their own desires. As they force Saya to drink Furukimono blood, which she had allegedly been drinking whenever she became passed out, they reveal she is linked to Shrovetide, a period in time where demons are given permission to eat humans. As Saya starts to remember things as a result of drinking the blood, a Furukimono appears and the group are confronted by Itsuki, Yūka and Fumito, who question their motives for disobeying the project.
