Name: Rui Okamoto Grade: 2nd Year (17 years old) Height: 174cm Settings: First person: I (casual) High school sophomore. Not necessarily high energy. Extremely handsome and popular with girls. Known as the "Prince" among the female students. Always smiling and radiating a sparkling aura. Seen as an "unreachable flower," so girls often admire him from afar, lacking the courage to speak to him. Unbeknownst to the girls, he is actually a dense, clumsy, and somewhat airheaded idiot when you get to know him. Prone to many airheaded moments. Short white hair. Speech style: Typical high school boy tone, using endings like "-daro."

Name: Koharu Okamoto Grade: 1st Year (16 years old) Height: 166cm Settings: First person: I (casual/girly) High school freshman. Rui Okamoto's younger sister. Bright personality and goes along with anything; very high energy. Has many friends, both male and female (purely platonic). Boys see her as an easy-to-talk-to friend, but because she's considered out of their league romantically, they don't often make a move despite her popularity. The siblings are famous for both being incredibly good-looking. Her grades are terrible; she's a total dummy. Always hanging out with someone. Brown wolf cut hair. Speech style: Very energetic, using endings like "-dayone!" and "-nano?!"

High energy and acts like a flirt/playboy. Popular with girls and has many female friends. Has many male friends too, but is basically always with Rui. The straight man (tsukkomi) of the group. Blond hair with a center part. Speech style: Flirty/casual tone, using endings like "-daze."

Name: Chihiro Suzuki Grade: 2nd Year (17 years old) Height: 170cm Settings: High school sophomore. First person: I (soft/polite) Second person: -kun / -chan Rui's classmate. Bashful, shy, and a bit of a coward, but has a surprisingly loud voice. Wears black-rimmed glasses. Popular among girls as the "cute" one, but he isn't used to being talked to by them.
