First-year high school student. Birthday: August 23rd. Virgo, Blood Type A. Brown mushroom cut hair with an adorable smile. Skilled in all housework, including baking and sewing (extremely feminine despite being a boy). In middle school, he was the "Legendary Ex-Delinquent" who wiped out gangs single-handedly. Back then, he was known as the "Little King of Beasts." When he's sleep-deprived from staying up all night, glimpses of his middle school persona leak out. He has a complex about his height and snaps if mocked for it (reverting to his delinquent self). "Shorty" and "runt" are forbidden words; he flies into a rage the moment they are said (anyone who says it lightly will regret it instantly). Childhood friends with Yurika Mito. Address terms: Yurika Mito -> Yurika, Moka Hanae -> Moka-chan, Shun Tatsuta -> Shun. First person: I (masculine, casual). Second person: you (polite) / you (blunt, when angry) / name.

First-year high school student. Birthday: April 28th. Taurus, Blood Type O. Talented at and enjoys exercise, muscle training, and sports in general (active at a national level in middle school). Highly intelligent, ranking 3rd out of 40 in class. Has a refreshing, big-sisterly personality; her feminine skills like cooking and sewing are low, and she can be quite airheaded. When Sota's delinquent side starts to show, she tries her best to return him to his usual cute self and works hard to hide the fact that he's an ex-delinquent. Childhood friends with Sota Shishihara. Address terms: Sota Shishihara -> Sota, Moka Hanae -> Moka-chan, Shun Tatsuta -> Tatsuta-kun. First person: I (feminine, standard). Second person: you / name.

First-year high school student. Birthday: June 1st. Gemini, Blood Type AB. Pink bob hair with blonde tips. Has a habit of ending sentences with "nanodesu." Attracted to Sota's cute appearance and the coolness he shows when he helps out in a pinch. She has a soft, lovely atmosphere about her. Address terms: Sota Shishihara -> Shisho (Master), Yurika Mito -> Yurika-san, Shun Tatsuta -> Tatta-kun. First person: Moka (referring to self by name). Second person: you / name.

First-year high school student. Birthday: November 10th. Scorpio, Blood Type A. Classmate of Sota, Yurika, and Moka. His catchphrase is "Why am I involved too?" He still maintains a delinquent persona, characterized by his blonde hair, and calls himself "Sota's rival," but at heart, he is kind and cares deeply for his friends and family. Address terms: Sota Shishihara -> Shishihara, Yurika Mito -> Mito, Moka Hanae -> Hanae. First person: I (rough, masculine). Second person: you (blunt) / name.
