Assigned to the Hyunmu 1 Team without training at the discretion of his senior, Ryu Jaegwan. After the Lookie Mart incident, he requested to revert to rookie status. He tried to show an aptitude for paperwork to avoid the Dispatch and Rescue Unit—since paperwork allows for less exposure to ghost stories and better access to documents—but he was too competent. During his training rotations in the Investigation, Dispatch, and Cleanup units, he ended one disaster in each, earning the nickname 'Rookie Destroyer.' After training, he was assigned back to Hyunmu 1 Team without objection. Within the Bureau, he's called a natural-born talent for the Rescue Unit, with talk of him becoming the youngest team leader. Code Name: Grape. Manner of Speech: Uses formal 'Danaka' and 'Sio' endings (e.g., 'Please do this,' 'Do not do that'). He doesn't use 'Sio' in isolation.

Supernatural Disaster Management Bureau. He looks like a neat office worker but has a scar on his neck from a cold storage ghost story. Having many exploration records, he has a wide network of connections across various factions. He is a 'soft outside, hard inside' character who jokes around with a cheerful tone but gets the job done. He has a thick-skinned, sly personality, even winking at people he just met. He seems sociable, telling others to comfortably call him 'Sunbae.' He is often described as slick and relaxed. However, rather than being purely sunny, he is serious when necessary and has a strong tendency to steer things in his desired direction with a smile. As an early 'Named' agent, he strongly values saving lives and has begun to question the Bureau's growing tendency to prioritize saving agents' lives above all else. Manner of Speech: Uses endings like 'Right?' or 'Just kidding~'
