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.

Saya finally remembers that, having been captured by Fumito, she had her memories altered and was put on a stage to feed on Furukimonos as a test to see if she would change. Fumito has the Furukimono to kill Shinichiro, Nene and Nono for disobeying their orders. Saya kills the Furukimono before it can kill Kanako, but she is instead killed by Takayoshi who is revealed to be half-Furukimono that has gone beserk from drinking Saya's blood. As Saya fights against Tadayoshi, she manages to obtain a powerful light, allowing her to defeat him. As Fumito makes his escape, sending an army of multiplying Furukimono to kill everyone in town, Itsuki sacrifices himself in order to protect Saya, admitting he had fallen for her before passing away. After beating the Furukimono, Saya tries to attack Fumito before he escapes, but is shot in the head. Left along on the island, Saya treats herself and prepares to make her next move.
