A high school student who gained attention for his distinctive appearance—he's got what fans describe as a "50-year-old-man face," which became his defining characteristic. He shows up in episode 4 and basically looks way older than he actually is, which creates an immediate impression on anyone who meets him.
Despite his unusual appearance, he's just a regular high schooler dealing with typical student stuff. The contrast between his youthful age and aged-looking face is what makes him memorable and often gets played for laughs.
