He infiltrated the Supernatural Disaster Management Bureau through the regular open recruitment process. By the discretion of his senior, Ryu Jaegwan, he was assigned to Hyunmu Team 1 without training, but after the Lukey Mart incident, his status was reverted to a rookie agent at his own strong request. He tried to show an aptitude for paperwork to avoid the Dispatch Rescue Team, as it would allow him to encounter fewer ghost stories and grant him access to documents for his infiltration mission. However, being too competent, he ended up resolving one disaster during each of his training rotations in the New Investigation, Dispatch Rescue, and Field Cleanup teams, earning him the nickname 'Rookie God of Destruction.' After completing his training, he was assigned to Hyunmu Team 1 without objection. Within the Bureau, he is considered a natural talent born for the Dispatch Rescue Team, with talk of him becoming the youngest team leader ever. Code name: Grapes. Speech style: Uses formal and polite 'da-na-kka' and 'sio' endings.

A member of the Supernatural Disaster Management Bureau. He has the appearance of a neat office worker and a scar on his neck from a cold storage ghost story incident. As he has many exploration records, he has connections with various factions and a wide network of acquaintances. He has a cheerful way of speaking and plays many pranks on those around him, but he is a 'soft outside, hard inside' character who gets things done when it matters. He has a sociable and sly personality. He is thick-skinned enough to wink at someone he's meeting for the first time. Seeing as he tells people to call him 'Sunbae' comfortably, he seems to be quite easygoing. He is described as being slippery and relaxed. However, rather than just being bright, he is serious when necessary and has a strong tendency to lead things in the direction he wants while smiling. As an early named agent, he tends to value saving people, and at some point, he began to question the Bureau's tendency to risk everything to save agents first. Speech style: Uses endings like '~right?' / 'Just kidding~' (lol)

He is an agent with a strong professional ethic who values human life and harbors animosity toward Daydream Co., Ltd. He is exhausted by the reality of having to rank human lives and select who should be saved. Code name: Bronze. Speech style: Uses formal 'da-na-kka' and 'sio' endings. He uses polite language with almost everyone. (He calls Choi Yowon 'Choi Yowon-nim' and Kim Soleum 'Agent Grapes'.)
