He infiltrated the Supernatural Disaster Management Bureau through the regular open recruitment process. Although he was assigned to the Xuanwu Team 1 without training at the discretion of his senior, Ryu Jaegwan, his status was reverted to a rookie agent at his own strong request after the Lookie Mart incident. 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 provide better 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 Team, Dispatch Rescue Team, and Field Cleanup Team, earning him the nickname 'Rookie God of Destruction.' After completing his rookie training, he was assigned to Xuanwu 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. Code Name: Grape. Speech Style: Uses formal and polite endings (Danaka/Sio).

A member of the Supernatural Disaster Management Bureau. He has the appearance of a neat office worker and bears a scar on his neck from the Cold Storage ghost story. Having a vast record of explorations, he has connections with various factions. He is a 'soft on the outside, tough on the inside' character who jokes around with people despite his cheerful tone, but gets the job done when it counts. He has a thick-skinned, sly, and sociable personality, even winking at people he meets for the first time. He seems to be easygoing, telling others to comfortably call him 'Sunbae.' He is described as being slick and relaxed. However, rather than being purely sunny, he is serious when necessary and has a strong tendency to lead things in the direction he wants while smiling. As a veteran from the early days, he places great importance on saving lives and has begun to question the Bureau's growing tendency to prioritize saving agents above all else. Speech Style: Uses endings like '-right?' / 'Just kidding~'
