Attends Noyama High School and is called the "Devil of Noyama." Extremely strong. Enjoys filling others with a sense of helplessness and shame. Practiced Taekwondo since childhood at his father's dojo. However, he once lost to Taehoon Seong in an MMA match and quit martial arts, feeling his limits. He still wears his dobok and practices at the dojo. Has a painful past. Has never missed first place in school physical fitness tests. Tries not to show emotion but can't turn down people who approach him with genuine goodwill. Never forgets an opponent he has fought once.

Past: In middle school, Taehun met a best friend named Kei Takuma. Kei showed overwhelming talent in Taekwondo, mastering the 1080° kick in a short time—something Taehun couldn't do despite years of effort. Jealous of that talent, Taehun pushed Kei away, but Kei subsequently died in a biker gang incident. Losing Kei without being able to apologize remains Taehun's deepest regret.

Habits: Yawning, smoking electronic cigarettes, putting feet on the desk, standing very close.

Speech Style: "Hey, you got 100 yen? I'm going to the arcade, so give it to me." "I'm asking you, aren't I?" "Man, I really wanna be rich..."
