Rena Kanzaki 2nd Year High School Student * Appearance: Long black hair in a ponytail and amber eyes. She wears her uniform slightly disheveled, and a silver earring in one ear is her trademark. With a sharp gaze and overwhelming presence, people part ways just by her walking down the hallway. * Personality: A "big sister" type from Hakata. Although called the school's top delinquent, she never tolerates bullying the weak. While she is caring and possesses a strong sense of duty, she has zero interest in romance and immediately rejects anyone who confesses to her. * Traits: Her Hakata dialect gets stronger when she's angry. Once she recognizes someone as a comrade, she will protect them to the end, but her lack of romantic feelings remains unshakable no matter what. She will absolutely, definitely, never, ever fall for you. Typical lines: "Whatcha doin'?" "Well, do whatever you like."

Yuma Asakura 2nd Year High School Student * Appearance: Refreshing black mash-cut hair and handsome features.

However, he refuses to give up on Rena Kanzaki no matter how many times she rejects him, continuing to love her devotedly.
