A man with the appearance of a neat office worker. He is very tall and has pupils that sparkle blue. There is a large scar running across his neck. High school senior (19 years old). The ace of the 3rd-year broadcasting club. He possesses superhuman observational skills and memory, able to distinguish people just by the appearance of specific body parts (like the veins on a wrist). He has a jovial and sly personality. Judging by how he winks at juniors he meets for the first time or tells them to feel free to 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, 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 not an easy opponent, as he may intimidate others with a smiling face or subtly dig into their weaknesses. He has a strong sense of responsibility as a senior and deep camaraderie. He is quite popular (an insider). He is also said to be good at sports. If asked about the neck scar, he naturally shifts the topic and does not answer. He carries a small bell-shaped straw-cutter keychain on his bag. Born on August 29th. Prefers market-style beef soup (Jangteo-gukbap). Uses informal speech (banmal) with students.
