A male student and the boyfriend of Senior. He goes on dates with Senior on a bench. If someone kicks a ball toward them and interrupts their date, he just kicks it back. Somehow, it flies all the way into space(?). He loves Senior. His looks are about average. Estimated to be 17 years old (10th grade). He seems to study hard.

A female student and the girlfriend of Junior. She is so busy watching the weasel couple that she doesn't notice Junior kicking balls next to her. (She just doesn't notice the ball-kicking; she listens to Junior well and loves him. She watches the weasels because she has nothing else to do, not because she's obsessed with them.) She is above average in looks and very pretty. She also seems to be good at studying. Estimated to be 18 years old (11th grade).

A pair of weasels living in a burrow right next to the bench where Senior and Junior date. They cheer when Junior kicks the ball. If he misses, the male weasel gets hit by the ball, retreats into the burrow, and comes back out (looking like he's in pain...). The male weasel has a yellow body, and the female has a pink body. They understand human speech but cannot speak it.

A group of 12 girls. They cheer for students studying with books in the library. Everyone says they are cute! They cheer by flipping, spinning, or opening books. Of course, they ask for permission first. It is said that Junior passed his exams after receiving their cheers. It seems to be somewhat effective...? All are estimated to be 17 years old (10th grade).

He looks like an adult, but seeing as he can't drink alcohol, he's a minor. He is a literal martial artist; his gi and skin are entirely white. Unfortunately, he suffered from premature hair loss and has fewer than 10 strands of hair... T_T For training, he punches objects like flowerpots or pots to send them flying. He has a special skill called the Combo. After punching a lightbulb away, he performs a 5-hit flowerpot-launching combo! The final blow sends the pot flying upward. Estimated to be around 19 years old (12th grade). He is male and has a strict father. As for studying... who knows. He might skip it to focus on training. He is taciturn and expresses emotions through facial expressions.

A delinquent who used to resort to his fists for everything (past tense). Now that he's found a good friend, he doesn't seem to use violence anymore. But he's still a delinquent... Male, estimated to be 19 years old (12th grade). He has a regent hairstyle and a rebellious look. Naturally, he's bad at studying.

Kim Il-jin's subordinate. Unlike the somewhat slim Il-jin, he is chubby. His nose is a round red ball, looking like Rudolph's. He has permed yellow hair and a delinquent vibe. He calls Kim Il-jin "Boss." He helps take care of Il-jin's "good friend." Naturally, he is bad at studying. Male, estimated to be 18 years old (11th grade).

A chameleon Kim Il-jin found in the bushes; he is Il-jin's "good friend." He has an extremely long tongue and eats microbes invisible to the human eye. Il-jin can't see them, but he praises him anyway. The microbes come in yellow and red varieties. Gender is... male?

The person responsible for kicking the ball toward the couple. She likes a guy named Hayato. Hearing that Hayato likes soccer, she practices her shots. She shows total dedication, doing overhead kicks and trapping. She appears quite pretty and is female. Estimated to be 17 years old (10th grade). Her grades are about average?

He sits on the bench... though it's unclear if he's actually watching Sora. He is the object of Sora's unrequited love and is male. He likes soccer. Estimated to be 18 years old (11th grade). He seems to be an average student.
