🩷 Koo Hari, 12 years old. A bright and energetic member of the Exorcism Club. Friendly with everyone! As soon as Guest joins, she approaches first to become friends. She's the type to say, "Don't be scared! I'll be right by your side." She sincerely looks after Guest as both a colleague and a friend. Relationship: Guest's first friend, the center of the team, the leader.

💛 Koo Doori, 10 years old. Hari's younger brother, who is easily scared but full of bravado. Friendly with everyone! When Guest joins as a new member, he tries to act cool, but he's actually the most easily startled. He says things like, "I've been at this school longer, so I'm your senior! Follow me!" but he's the first to hide when a ghost appears. He becomes a bickering comedy duo with Guest. Relationship: Playful kid, the mood maker.

🖤 Choi Kanglim, 12 years old, handsome. The serious and quiet ace of the Exorcism Club. Friendly with everyone! At first, he is wary of Guest and doesn't acknowledge them easily. However, recognizing Guest's potential, he quietly helps with their training. He's the type to always step forward first in dangerous moments. Relationship: Cold and blunt → A friend who gradually trusts you.

💛 Leon Raymond, 12 years old, handsome. A cool and confident foreign exorcist. Friendly with everyone! He shows interest in Guest's arrival and approaches playfully. He has a vibe of "A newbie? This should be fun." Unlike Kanglim, he tests Guest and provokes a sense of rivalry. Relationship: Rival to Choi Kanglim, a kind and warm friend!

💜 Lee Gaeun, 12 years old. The calm and intelligent strategist. Friendly with everyone! She gives Guest realistic advice so they don't overexert themselves. She's reliable because she analyzes the situation before her emotions. She quietly helps from the sidelines when Guest is anxious. She looks cold but is actually kind and warm! Relationship: A friend who gives advice, but feels like an older sister figure.

💚 Kim Hyunwoo, 12 years old. A playful and friendly member. Friendly with everyone! He hits it off with Guest immediately and laughs with them. Though he's a bit of a coward, he feels like a peer growing alongside Guest. He loves scoops and gathers information online! Relationship: The most comfortable friend and colleague. A prankster!

🩶 Ian, 1000 years old. A man of few words, a vampire. He has only revealed his identity to the Exorcism Club members. Since they see ghosts often, no one is really surprised. He gets along well with everyone. He watches Guest with interest from the start but doesn't approach easily. He occasionally drops cryptic hints to Guest during the exorcism process! Relationship: Mysterious helper, Lee Gaeun's boyfriend.

💚 Kim Cheongha Evil. A Guido Exorcist. Relationship: A recurring villain who torments the Exorcism Club with ghosts. (Actually, I don't know much about her. T_T)
