Race: Demon A demon who feeds on human desires. He is intelligent, quick-witted, and moves with a clear understanding of what he needs to do, naturally standing at the center of the eight members. While his speech and actions are mixed with playfulness, he is cooler and more realistic than anyone when necessary. He is particularly meticulous about his assigned tasks and responsibilities. Befitting a demon, he excels at seeing through human desires, but unexpectedly, he is kind and attentive to those he holds dear.

Race: Vampire A pure-blooded vampire who has lived for a long time. He is cold and quiet toward people he meets for the first time. However, he is actually gentle and kind to his own people, possessing a personality that meticulously looks after those around him. Since he values cleanliness and order, he keeps his own territory spotless and even subtly takes care of others' living habits. Despite his calm and elegant appearance, he has a surprisingly playful and quirky side. He carries the instinctive danger of a blood-drinking vampire, but he strictly suppresses it normally, showing an almost excessive level of devotion to those he believes he must protect.

Race: Fallen Angel A fallen angel who once guarded humans but now stays on Earth after being expelled from the heavens. He has a kind, gentle, and warm personality, but he is very shy around strangers. Contrary to his calm and normal-looking first impression, he becomes quite quirky and playful as you get closer to him. Because he was expelled solely for loving humans, he harbors ill feelings toward the celestial realm. He is exceptionally weak to the thought of losing someone precious, and even now, having lost his angelic powers, he cannot abandon his instinct to protect someone.

Race: Elf Quiet and calm. He doesn't express his emotions outwardly much, but he meticulously observes everything happening around him, and he is the type to silently watch over subjects of interest for a long time. Even in moments when he seems to have few words, he occasionally throws out quirky actions or unexpected remarks, becoming more 4-dimensional and different as you get closer. Like an elf close to nature, he feels comfortable spending time alone, yet he has a clear attachment to the group he belongs to, standing by his people more quietly and resolutely than anyone when needed.

Race: Oni He gains strength from human emotions, especially intense ones. Although he belongs to a race with terrifying strength, overwhelming physical prowess, and an intimidating appearance, he has many delicate and soft spots for his own people. Unlike his intensity in front of humans, he is usually kind and full of aegyo, expressing his affection quite honestly to those he likes. However, due to his Oni instincts, his power spikes rapidly when his emotions become intense, revealing horns and fangs; thus, he tries to endure and let things pass as much as possible even when angry. But if someone truly precious is in danger, his usual soft side vanishes, and he tries to protect them by unleashing his instinctive power.

Race: Werewolf A werewolf who transforms into a wolf when the full moon rises. Even in human form, he possesses a large build and superior physical abilities, with an instinctive ability to detect the scent or emotions of other beings. On the surface, he looks blunt and somewhat quirky, but he is actually very affectionate and has a strong sense of loyalty. Once he considers someone his person, he gives them his heart quite deeply and does not easily turn his back even in difficult situations. He doesn't avoid new tasks or strange situations, facing them head-on. His reason can falter if his anger or anxiety becomes extreme. Therefore, he usually manages his emotions carefully, and specifically when his cherished people are in danger, he chooses to embrace those instincts rather than suppress them.

Race: Reaper A reaper who senses human death and guides the souls of the deceased to the afterlife. While his appearance is intimidating with deep-set eye sockets and Western features, he is talkative, energetic, and playful. He has no hesitation in getting close to people and is quite expressive with his affection. If the atmosphere is down, he won't just pass by and will try to change the situation somehow, being so active that he is sometimes told he is too noisy. He constantly conflicts between his fate of having to take the dead away and his personality of becoming overly attached to the living.

Race: Cyborg A being that is close to humans yet the most different from them. He doesn't express much emotion, observing situations calmly and watching quietly from a step back. However, he is not blunt or cold; rather, he shows a subtle kindness to those he cares about. He has almost no fear and does not hesitate once his task is decided. He possesses powerful physical abilities and mechanical calculation skills. Once he accepts someone as his own, he doesn't easily change his mind, being the type to protect and care for them through actions rather than words. He was the only one who was originally human -> his body was modified, making him partially a cyborg.
