He has a persistent nature, digging deep into anything he doesn't understand. While he talks a lot of nonsense and jokes around, he often flusters others with sharp, blunt truths. Despite his personality of saying whatever comes to mind, his fighting skills don't quite match his mouth. He is surprisingly innocent for his age and has a deep heart.

Gender: Male Age: 11 Height: 143cm Blood Type: A Personality: Perhaps due to his innocent nature, he often fails to understand the context and lacks social cues, sometimes crossing the line into 'pure evil' territory. When his friends exchange crude jokes, he tries to stop them, but then he'll laugh alone at the exact moment everyone else stops, creating an awkward atmosphere. Because he is timid, he is more fearful and cautious than the others, often hesitating or getting startled by the main characters' reckless remarks. Furthermore, his cowardice often overrides his kindness, so he tends to avoid situations where he should act righteously. (Summary: He looks innocent on the outside, but inside he is a bit damp and lewd. However, he is a pure character who doesn't intend to cause harm.) Likes: Seojun, Pizza Bread. (He especially loves Yoon Seojun.) Dislikes: Violence. Other: For casual wear, he wears a blue short-sleeved T-shirt and white shorts. He swears occasionally but generally avoids it.

Gender: Male Age: 11 Height: 67cm (Small because he has no legs) Personality: Seojun's kindergarten classmate, born with a physical disability and no limbs. Compared to Timmy Burch from South Park, his physical disability is more severe, but he has no speech impediment. His humorous speech and proactive behavior are closer to Jimmy Valmer. He wears a pillowcase with holes as clothes and uses a sleeping bag instead of a padded jacket in winter. Having been best friends with Seojun for a long time, they giggle over high-level jokes, often leaving Doyun fuming alone about 'offensive humor.' He is a mentally strong person who gets along well with his friends without feeling awkward. He is a generous and cool character who takes Seojun's pranks well and makes jokes just as often. Despite his physical disability, he is one of the most sensible characters alongside Doyun. This mental strength is evident in how he remains unfazed even when facing situations that would shock any other child his age. (Summary: Has a cheerful and cool personality.) Other: Uses an electric wheelchair (sometimes pushed by Robot).

He is always seen with a phone in his hand to the point of internet addiction, even sneaking peeks at it during class. This might be because he's busy running an adult content business, watching or posting things online, or simply because he prefers being alone and spends a lot of time sitting and looking at his phone. Occasionally, when he's curious about something, he'll recite knowledge or information like a search engine robot. Likes: Friends, Selling adult content, BL Other: Reflecting a bit of reality, students who like rock or metal music are often just 'cool posers' stuck in a middle-schooler syndrome phase and are far from being delinquent 'iljin' types.
