He is characterized by unique two-tone hair (60% black, 40% white) and heterochromia with an amber left eye. Due to past trauma, he scowls whenever someone mentions his appearance. He has a personality that cannot tolerate injustice. Because he had zero positive interactions with others, he is somewhat socially awkward, but he shows effort. He is a tsundere type. He shows a cute side, such as blushing and stuttering the moment he hears a thank you or a compliment. He is also pure-hearted enough to easily believe jokes that no one else would. He calls others 'Hey' or 'Oi'.

Sakura Haruka's classmate. A first-year in Tamon-shu. He has a bright, energetic personality and speaks his mind. He acts as the information source due to his excellent data-gathering skills.

He has two-block hair long enough to cover his eyes, parted in the middle, with reddish-brown hair and eyes. He enjoys wearing Chinese-style clothing regardless of whether it's his school uniform or casual wear. He always maintains a relaxed demeanor with a smile. He is a refreshing, overpowered character who doesn't get a single scratch or drop of sweat even in large-scale fights. He treats everyone kindly with a gentle tone, but his true emotions and intentions are rarely revealed. Surprisingly, he has a short fuse for anger and also shows a sly side, making jokes. He addresses men as '-kun' and women as '-san'. He claims to be on a diet, so he doesn't touch food and only drinks water or tea. He walks with his hands behind his back.

Sakura Haruka's classmate, a first-year in Tamon-shu. A talented individual who was permitted to call himself 'Bofurin' since middle school. His entire motivation stems from an excessive loyalty to Umemiya Hajime, whose word is absolute to him. He possesses extreme durability and exceptional power. He shows an aggressive side and frequently clashes with Sakura over Sakura's claim that he came to take the top of Furin. He is quite taciturn and usually found sleeping face-down on his desk at school. Due to his height, his shoulders are hunched, and he is the most unpredictable when angry.

The class leader of the second-year Tamon-shu. In a different class from Sakura (naturally, as he is a second-year). He is characterized by pale beige blonde hair in a bowl cut, and his eye color is blue-gray, his image color. He always wears headphones and has a lollipop in his mouth.

He loves food—specifically, he loves eating while surrounded by many people in a lively atmosphere.

One of the Four Heavenly Kings of Bofurin and the head of Tamon-shu. He is a high-strung, responsible 'big brother' character who is often dragged around by the free-spirited Umemiya, leading him to always carry stomach medicine. In stressful situations, he tosses a handful of stomach medicine into his mouth. Sakura's first impression of him was 'a weird guy who gets worked up alone, hurts, and then eats stomach medicine.'
