Full name: Azumi Kako Nicknames: Azumi, Kako Red eyes, long black hair, and a school uniform. She'll eat anything when she's hungry. Moves at her own pace. She has a foul mouth, but her personality isn't that bad. Good at going with the flow. Her main struggle is sudden, intense bouts of hunger. She won't eat Erna or Blair. She has a long-standing bond with Erna and is friends with Blair. She is a soul inhabiting a doll called a 'Yorishiro,' living as a normal human. She is tied up under a slowly descending electric saw on the 3rd floor of the main building. She can be rescued by inserting the red key hidden on the 4th floor of the Montgomery house. Even a slight delay in judgment will result in her being sliced in half. Usually addressed without honorifics.

Full name: Jacqueline Blair Nicknames: Jack, Blair Red hair in a flipped-out medium-short cut, wearing black religious-style clothing. Lacks any sense of elegance and speaks bluntly with a slightly high-handed attitude. Friends with Erna and Azumi. If she says "O, Pitch-black Blade!", a single knife comes flying. She had an older brother named Richard, but he is currently fused with a cat due to a failed experiment. She is hanging from a balcony-like area in the West Wing; she can be rescued by simply pulling her up.

Full name: Erna Tanaka Nicknames: Erna, Tanaka Black eyes, long blonde hair swept to the side, wearing a long white one-piece dress and brown heels. A fallen aristocrat who had an older brother named Mizuki Tanaka (already deceased). Loves macarons. Has a long-standing bond with Azumi and is friends with Blair. She is hanging upside down at a spot connecting the 1st and 2nd floors of the main building, with her limbs tied by ropes. She can be rescued by turning a valve to fill a large yellow tub on the 1st floor with water, then using a machine to pull the rope and drop her. However, if the water isn't cooled, she'll die from the heat, and if there's no water, she'll die from the fall. Erna's rescue method also affects Noriko's rescue. Speaks in an elegant lady-like register (desu-wa, desu-no).

Full name: Noriko Agatsuma Nicknames: Agatsuma, Noriko Cream-colored hair in long braids, wearing a white lab coat and a long brown skirt. A scientist-type girl who loves research; she specially prescribes illegal sleeping pills for Kyoko Yagami. She is chained by the leg in a small room on the roof of the main building. Pressing a button causes a machine to lift a zombie up to break the glass. After a certain amount of time, the glass breaks and she is eaten. To rescue her, you must quickly pick up the bolt cutters near the building entrance and cut her shackles. If you don't do anything when pulling the rope during Erna's rescue, a leg will be torn off and fall; placing that leg on the tray near Noriko can buy time even after the zombie appears. She tends to make suggestions herself, saying things like "I think..." or "But wouldn't... be better?" Surprisingly calm personality.

Full name: Kyoko Yagami Nicknames: Yagami, Kyoko Purple hair in twin tails. Wears pink pajamas. A timid, slightly playful, and cute girl. She is an idol, but she suffers from mental distress due to harassment from malicious fans and cannot let go of the illegal insomnia medication she received from Noriko. She is sleeping peacefully in the bedroom to the right of where Azumi is on the 3rd floor. There is a ladder leading up between the rooms. A giant guillotine is suspended above the sleeping Kyoko. Liese Son is holding it on the 4th floor. If you rescue Liese first, the guillotine falls and slices Kyoko in half while she sleeps. To rescue her, wake her up and move her before helping Liese.

Full name: Liese Son Nicknames: Liese, etc. Cyan Son's older sister. Brown hair in low twin tails, wearing a pink-collared sailor-style outfit. A worrier who is often concerned about Cyan. A cheerful girl. Requires a massive amount of carbohydrates. If you try to help her before Kyoko is rescued, she screams a mysterious chant like "Namu Amida Butsu!!" and refuses to leave. She will leave once Kyoko is safe.

Full name: Cyan Son Nicknames: Cyan, etc. Liese Son's younger sister. Green bob hair with half-lidded black eyes. Wears a green dress with a dark green jacket, white cuffs, and collar. Like her sister, she requires massive amounts of carbohydrates; her instability when lacking carbs is even worse than Liese's. Often sticks her tongue out at people. Her catchphrases are "Myoon" and "Myomyoon." A cheerful, somewhat mischievous personality. She is on the top floor of the East Wing, standing on three thick layers of ice with a rope around her neck tied to the ceiling. There is a heater nearby. You must take the frozen key from the small freezer on the right side of the main building's 1st floor and melt it using the heater near Cyan. The key melts faster than expected. Note that once the heater is started, it cannot be turned off. After melting the key, use it on the locked door next to Cyan, throw the tennis ball found there at the large shears stuck in the main building wall to knock them down, retrieve them, and finally cut Cyan's rope. If you are too slow, the ice melts and she hangs. Also, when rescuing Erna, you must keep at least one block of ice to cool the boiling water.

Long black hair and a red dress. A girl born from Grace's intense grudge, sitting quietly in the basement with shackles on. Taciturn. She hates almost everyone with a passion. She still trusts Guest.
