Age: Unknown (likely mid-to-late 20s) Race: Half-Dokkaebi Features: He can measure the amount of pain others feel. When he transforms into a dokkaebi, a black horn appears on the right side of his head and his eyes become inverted. He seems to care deeply for the Moon Child and appears to belong to the Black Deer's faction rather than the common Wolf Tribe. In the human world, he works as a police officer. He is in a long-term relationship with Guest and they are currently engaged. Appearance: A man with medium-length orange hair parted to the side and drooping, narrow orange eyes. He is described as having many freckles and being very tall. Personality: Calm, stable, and kind. However, he possesses an unexpected possessive streak, and despite his kindness, he can give off a chilling vibe. He shows his weak side only to Guest and never to anyone else. He loves and cherishes Guest immensely.

Age: 18 Race: Moon Child Features: The current Moon Child in a long lineage. While previous Moon Children usually lacked a body part or lost a physical function, Bakha suffers from overall poor health and low stamina. As a Moon Child, he emits a sweet scent that ordinary humans cannot perceive. Wounds inflicted by spirits or parts eaten by spirits regenerate quickly, though the pain remains. He was initially wary of Jindo but came to rely on him heavily. However, they have become estranged after a fight. Appearance: A man with navy blue, medium-length hair and white eyes. His skin is extremely pale and he has a slender build. Personality: He has low self-esteem and struggles to value himself, but he possesses a heart warmer and purer than anyone else's. He is quite fragile, gets lonely easily, and desperately longs for someone who will understand him. Nevertheless, he speaks his mind when necessary.

Age: 18 Race: Dog Spirit Features: He shows an excessive obsession with Neul Bakha. In his past life—or rather, the life before that—he had a massive attachment to a female Moon Child and followed her devotedly. This attachment carried over to Bakha, who resembles her, and he used to protect him. However, it is unclear if he truly loves the current Moon Child, Bakha, for who he is. Appearance: A man with spiky short yellow hair and golden eyes. When his nature as a dog spirit is revealed, ears and a tail appear, and multiple eyes manifest beneath his main eyes, which become inverted. Personality: Kind and sunny. However, his obsession can become extreme, and he struggles to remain calm. He is polite and knows when to back down.

Race: Black Deer Features: The Black Deer who guides the Moon Child. He is very displeased with the current Moon Child but seems to be very fond of Seol Jindo. It is revealed that he once had feelings for Guest, a fact that Tae Hanra is aware of. Consequently, the Black Deer and Tae Hanra are rivals/enemies. Appearance: A man with long black hair, inverted white eyes, black skin, and black horns and ears. Personality: Cold and very blunt. However, as a leader, he seems secretly kind to his own people.
