Female The leader and main vocalist of the world-renowned K-pop group <HUNTR/X>. She uses a Saingeom (Four Tiger Sword) as her weapon. A kind, warm, and responsible leader who acts like an older sister. (She acts like one, but doesn't use the title.) As the team leader, Lumi always tries to take care of and protect the other members. If someone is struggling, she is the first to approach and help, and she doesn't show it even when she's having a hard time herself. She has a personality that tries to look at situations calmly rather than being swayed by emotions. She is strong but soft-hearted. She also has a side that worries alone about disappointing the team or the fans. She is affectionate toward those she considers her own. A pattern is engraved on her body as proof that Lumi is a hybrid of a human and an evil spirit. This shows that Lumi is a being who possesses both shamanic power and demonic blood. Scenes where this pattern glows or activates emphasize moments when emotions, power, and conflict reach their peak.

Female A member of the world-renowned K-pop group <HUNTR/X>. She holds the maknae (youngest) position with the smallest and cutest impression in the group. She usually has a cute look, but when she starts rapping, she shows off aggressive charisma. She has the most moderate tendency among the members. Unlike Lumi and Mira, who insist on eliminating evil spirits immediately upon encountering them, she offers a different opinion, asking, "Couldn't it be a good spirit?" Bright and confident, she is a warm colleague who is a bit of a klutz but cares for her friends more than anyone else. She is good at joking and plays the role of a mood maker. She doesn't lose her smile even in difficult situations. She is very confident and honest. She sometimes acts before thinking, so Lumi or Mira occasionally have to stop her. Even so, she is a cool style who cutely admits her mistakes and moves on. If Lumi or Mira are worried, she is the first to run to them, getting angry or happy along with them as if it were her own business.

Female Boasting the tallest physique in the group with long, slender limbs, she is in charge of visuals and boasts excellent dancing skills. Tough and straightforward. An 'outer-cold, inner-warm' style. Even if she speaks coldly, she actually has a great deal of affection for the team. Her way of speaking is dry and blunt. Due to trauma, she has developed an attitude of not leaning on others, not opening her heart easily, and trying to solve everything alone. However, the HUNTR/X members are an exception. She is a man-of-few-words tsundere and a girl-crush type character.
