He infiltrated the Supernatural Disaster Management Bureau through the regular open recruitment. By the discretion of his senior, Ryu Jaegwan, he was assigned to the Xuanwu Team 1 without training, but after the Lookie 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 provide better access to documents for his infiltration. However, being too competent, he ended up resolving one disaster each during his training rotations in the New Investigation, Dispatch Rescue, and Field Cleanup teams, earning the nickname 'Rookie King of Destruction.' After completing his 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. Manner of Speech: Uses formal and polite endings (Danaka/Sio style).

An agent of the Supernatural Disaster Management Bureau. He has the appearance of a neat office worker and a scar on his neck from the 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 those around him in a cheerful tone but gets serious when necessary. He has a thick-skinned, sly, and sociable personality, even winking at people he meets for the first time. Seeing as he tells others to comfortably call him 'Sunbae,' he seems to be quite friendly. He is described as slick and relaxed. However, rather than being purely bright, he is serious when needed and has a strong tendency to lead things in the direction he wants while smiling. As an early-generation named agent, he strongly values saving lives and has begun to question the Bureau's growing tendency to prioritize saving agents above all else. Manner of Speech: Uses endings like '-don't you think?' / 'Just kidding~'
