Gender: Male Age: 11 Height: 138cm Blood Type: AB Personality: Characterized by his spiky, shaggy hair, he speaks his mind without worrying about social norms. He has a persistent personality, digging into things until he understands them. He talks a lot of nonsense and jokes, but he also flusters others with sharp, blunt facts. While he has a personality that blurts out 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. (In short: On the outside, he says what he wants and tends to fluster others, but on the inside, he is quite thoughtful. He is relatively active, participates eagerly in various activities, and is very assertive.) Likes: Doyun, seasoned fried chicken (He especially loves Doyun very much) Dislikes: Violence, homework Other: For summer or casual wear, he wears a white short-sleeved T-shirt and yellow shorts. His pronunciation of 'Oh shit' is very slick; it seems to be a habit. He attends Taekwondo (Red belt). He swears quite a bit.

Gender: Male Age: 11 Height: 143cm Blood Type: A Personality: Due to his innocent nature, he often fails to understand context and lacks social cues, but sometimes he goes beyond just being clueless and shows a side close to 'pure evil.' When his friends exchange crude jokes, he tries to stop them, but then he'll laugh alone at the exact moment the friends start to stop because it's gone too far, creating an awkward atmosphere. Because he is timid, he is more fearful and cautious than the others, and as a result, he often hesitates or gets startled by the main characters' unfiltered remarks. Furthermore, since his fear takes priority over his kind nature, he tends to avoid situations where he actually needs to act righteously. (In short: He looks innocent on the outside, but inside he's a bit damp and devious. However, he's a pure character as long as he's not causing harm.) Likes: Seojun, pizza bread. (He especially likes Seojun very much.) Dislikes: Violence. Other: For casual wear, he wears a blue short-sleeved T-shirt and white shorts. He swears a little, but very rarely.

Gender: Male Age: 11 Height: 67cm (Small because he has no legs) Personality: Seojun's friend from kindergarten, he is a person with a physical disability who was born without limbs. Compared to Timmy Burch from South Park, his physical disability is more severe, but he has no speech impediment. His behavior of enjoying humor and his proactive nature are closer to Jimmy Valmer. He seems to wear a pillowcase with holes in it instead of clothes, and in winter, he wears a sleeping bag instead of a puffer jacket. Perhaps because he's been best friends with Seojun for a long time, they giggle while making high-level jokes with each other, creating situations where Doyun is the only one getting worked up over derogatory jokes. He is one of the mentally strongest characters who gets along well with his friends without awkwardness. He is a big-hearted and cool person who takes Seojun's pranks well and makes jokes as often as Seojun does. Despite his physical disability, he is one of the most sensible characters along with Doyun. This mental strength is also shown in how he rarely gets surprised even when experiencing situations that would shock any other child his age. (In short: Has a cheerful and cool personality) Other: Rides an electric wheelchair (Sometimes the Robot pushes him) Likes: Friends Dislikes: Braised dried pollack (Kodari-gangjeong) Other: Despite being born without limbs, he uses an electric wheelchair with a controller on the armrest. He makes a "Te-heh" sound when he laughs.

Gender: Male Age: 11 Height: 151cm Blood Type: B Overview: From his first appearance, he showed a lecherous tendency with no hesitation about sexual matters, such as trying to sell a video of his parents having sex for a thousand won. He always has a phone in his hand to the point of appearing addicted to the internet, and he can be seen secretly looking at his phone even during class. This might be because he's always busy watching or posting adult content online as part of his business, or it might just be that he prefers being alone and spends a lot of time sitting and looking at his phone. Sometimes, when he's curious about something, he recites knowledge or information he searched for like a robot. Likes: Friends, selling adult content, BL Other: Reflecting reality to some extent, students who like rock or metal music are usually just 'cool-wannabes' stuck in a middle-schooler syndrome phase and are far from being delinquent bully types.
