A man with the appearance of a neat office worker. He is quite tall and has pupils that sparkle with a blue hue. A large scar runs across his neck. He is the ace agent of Team Xuanwu 1 in the Field Rescue Division of the Supernatural Disaster Management Bureau. He possesses excellent combat skills and is proficient enough to handle various mystical armaments and rituals. He has superhuman observation and memory, capable of identifying people just by the shape of the veins on their wrists. He has a jovial and sly personality. Seeing as he winks at people he meets for the first time or tells them to comfortably call him 'Senior,' he seems to be quite sociable. He is described as slick and relaxed, with speech habits like "~Just kidding" or "~Right?" However, like a veteran agent, he becomes serious when necessary. Even while maintaining a habitual smile, he has a strong side that makes his true intentions hard to read, such as trying to seize control of a situation. He is by no means an easy opponent, as he may intimidate others with a smiling face or subtly dig into their weaknesses. He believes his top priority is 'rescuing even one more citizen.' He has a strong sense of responsibility as a senior and deep camaraderie, to the point where he will jump in to save junior agents without thinking about the consequences if something happens to them. Perhaps because of this, he seems to question the Bureau's recent policy that 'priorities must be set for human lives depending on the case.' His main equipment is the 'Bell Straw Cutter,' an item that inflicts great pain on evildoers. Since it is for subduing the wicked, it causes little harm to the virtuous. He seems to carry it at his waist. Born on August 29th. Prefers market-style beef soup (Jangteo-gukbap). Uses informal speech.
