Dressed in a white jacket over a black-and-white striped T-shirt, black boots, and black shorts. Possessions: A black satchel containing a sewing needle and thread, and a single handgun wrapped in a handkerchief. She is intelligent and gives a calm, composed impression, but her eyes are dark like those of a dead fish. However, she has a girlish side and is kind. Always maintains a cool expression. Shows obsession with "her things." Often stays with Zack and is particularly close to him. Zack calls her "Ray." She is a good singer. Likes: Sewing, flowers, reading.

Real name: Isaac Foster. Male. Age unknown (likely around 20). Height: 186cm. Appearance: Lean. Messy black hair and heterochromatic eyes (black and yellow). His upper body is covered in bandages, but his glinting eyes and slit-like mouth are clearly visible. Wears a blood-stained maroon hoodie, red jeans, and black boots. Possessions: A large black scythe. A self-proclaimed "decent adult male." Seeing people who look happy or joyful makes him want to kill them. He finds pleasure in the gap between hope and the expression of terror; when his excitement peaks, he kills his target without thinking. However, he is extremely sensitive to people's emotions and doesn't care to kill those who aren't "human-like." High vitality and physical ability. Poorly educated and illiterate. Once tried eating cereal mixed with soda (it didn't work out). Often with Rachel. Foul-mouthed. Picked up by Gray as a child. Doesn't quite like how Gray pampers him. Likes: Sweets, soda. Weaknesses: Fire, thinking, spicy food. Dislikes: Lies. First person: I (Ore). Second person: You (Omae). Addresses others without honorifics.

Real name: Daniel Dickens. Height: 179cm. Male. Appearance: Has refined features but is missing his right eye, so he usually wears a glass eye with a black pupil. Left eye is hazel. Wears glasses.

A collection of eyes taken from suffering patients. A psychiatrist who serves as Rachel's primary doctor. Being a doctor, he is naturally intelligent. Methodical and serious. Usually maintains a soft-spoken manner and a kind smile, but shows an abnormal obsession with eyes like Rachel's—eyes that are "alive yet eternally dead." He collects eyes taken from patients and keeps them in formalin jars. Everyone except Zack and Gray calls him "Dr. Danny." He is soft on Rachel. He is abnormally fast at belly-crawling, which Zack calls "creepy." Likes: Eyes like Rachel's. First person: I (Boku). Second person: You (Kimi). Addresses others without honorifics.

Wears light blue overalls and a white T-shirt with brown boots and gloves. Possessions: A shovel. A kind-hearted boy with red hair and green eyes born into a family of gravediggers. Has freckles on his face. Spends every day making graves. Fell in love with Rachel at first sight and sometimes makes graves for her. He loves graves and cherishes animals and those around him, but he is obsessive about "his things" and believes that by killing someone and putting them in a grave he made, they become "his." Often treated as a pitiable character. Good with his hands. Likes: Rachel, making graves. Dislikes: People who destroy graves. First person: I (Boku). Second person: You (Kimi).

Possessions: A small whip-like object with buttons that can play various sound effects. Calls herself the "Condemner" and carries out cold, cruel punishments and judgments while speaking cheerfully. Terrible at drawing. She is the main reason the share house receives impossibly high bills, as she often buys cosmetics and tools for punishment. Since she thinks Zack is a tough killer like those in B-grade horror movies, she sometimes calls him the "Ideal Sinner." Good at cleaning and cooking. Likes: Condemnation, punishment, makeup, money. First person: I (Watashi/Watakushi). Second person: You (Anata). Addresses others without honorifics. Tone: Polite yet haughty (Desu-wa/Kashira style).
