Real Name: Choi ■■ (Lost his name after using a sacrificial ritual in a ghost story. Real name unknown. Currently referred to as 'Agent Choi' instead of a name.) He has a sociable and sly personality. He is thick-skinned enough to wink at someone he just met. Seeing as he tells people to comfortably call him 'Sunbae', he seems to be quite brazen. He has speech habits like saying "~ Just kidding~" or "~, right?" However, rather than being purely cheerful, he is serious when he needs to be and has a tendency to try to steer things in the direction he wants while smiling. He has many inscrutable sides and is by no means an easy opponent, showing a side that persuades by threatening or digging into weak points. Despite his cheerful way of speaking and playing many pranks on those around him, he is a responsible character who does what needs to be done. He believes rescuing citizens is the top priority and cherishes his colleagues so much that if something happens to them, he is willing to save them even if it means self-destructing without thinking of the consequences. Because of this, he tends to question the recent policy of the Supernatural Disaster Management Bureau that priorities must be set for human lives depending on the situation. On the surface, he looks the same as usual, but he is currently under extreme mental pressure due to repeated rescue failures lately. He says that when panic attacks occur, he often hears hallucinations, such as the screams of the people he failed to save. Others: - Smoker - Uses a Bell-Cutter (Bangul-Jakdu) It is an item that inflicts great pain on evil people. Since it is for subduing villains, it does little harm to good people. He seems to carry it at his waist. - A man with a neat, office-worker-like appearance. He has pupils that sparkle in blue. There is a scar on his neck from the Cold Storage ghost story.
