Sakimura Yuuki, the sporty schoolboy. - knows karate, likes Uehara, dislikes us. Is stupid most of the time.
Kayano Rina, the steady office lady. - also a triple agent and a co-worker at IAE, an organization that the whole project belongs to. Is mortally afraid of Seiji, but was openly antagonistic towards us when she knew we were not him, too. Wants the book for some reason - allegedly to destroy it.
Uehara Shizuka, the bubbly schoolgirl. - also a miko family descendant whose sister Seiji and Juuzo screwed over under unknown circumstances. The character we most interacted with. Was lured here with a promise of revealing the fate of her sister.
Sakaki Okitsu, the grumpy author. - a collaborator of late Hidetaka Matsui and Amanozaki's role model. Studies occult for a living.
Maeda Nami, the proud heiress. - former Seiji's passion and a heiress to the declining Maeda family. A less-than-enthusiastic fiancee to Taketatsu. Loves Seiji, but her feelings are probably misplaced.
Taketatsu Shinichi, the quiet entrepreneur. - also known to kill everyone, sacrifice Mitsuki, and whore himself to the old man to weazel out of dying. He did not succeed.
Sawada Junichi, the friendly celebrity. - an actor and Seiji's henchman-in-hiding. Pretends to be a no-brains simpleton. Might have been responsible for some of the shenanigans during the previous nights.
Okuyama Midori, the outgoing trainee nurse. - is an associate of Tokigawa. We clashed with her from time to time, but never interacted in a meaningful way.
Tokigawa Kou, the responsible trainee doctor. - is an associate of Okuyama. Was not supposed to be at the hospital on the day of the experiment. Often assumes the role of the leader and tries to keep people together.
Mori Akiyama, the gruff detective. - is investigating Shinohara family over a series of incidents. Protective of Mitsuki. Tried to shoot himself over the memory of 'Kana', whoever that might be.
Iwano Mitsuki, the sensitive little girl. - is spiritually sensitive. Suffers from an unknown 'desease', for which she is supposedly treated in Ikei. Ended up as a sacrifice during the third night and has not been seen since.
Amanozaki Touko, the eccentric (self-proclaimed) psychic. - a lovely hack who comes from a family of yakuza or something. Was lured here with a promise of revealing an occult mystery.
