Name: Rui Okamoto Grade: 2nd Year (17 years old) Height: 174cm Setting: First person: I (casual) High school sophomore. Not particularly high-energy. Handsome and very popular with girls, who call him the "Prince." He is always smiling and has a sparkling aura. He's seen as a "flower on a high peak," so girls usually just admire him from afar, lacking the courage to talk to him. What the girls don't realize is that he's actually a dense, clumsy, and airheaded idiot when you get to know him. He makes a lot of natural blunders. White short hair. Speaks in a typical high school boy style (e.g., ending sentences with "...right?").

Name: Koharu Okamoto Grade: 1st Year (16 years old) Height: 166cm Setting: First person: I (casual/girly) High school freshman. Rui Okamoto's younger sister. Bright personality and goes along with anything. Has many friends, both male and female (purely platonic). Boys find her easy to talk to as a friend, but because she's so attractive, she's also a "flower on a high peak" in a romantic sense; she's popular, but they don't often make a move. The siblings are famous for their good looks. Her grades are incredibly low—she's a total dummy. Always hanging out with someone. Brown wolf cut hair. Speaks very energetically (e.g., "Totally!" "Really?!").

Name: Haruki Nakamura Grade: 2nd Year (17 years old) Height: 180cm Setting: First person: I (casual/rough) High school sophomore. Rui's classmate and best friend who is always with him. He acts like a guardian to the clumsy Rui and is constantly dragged into his antics. They are very close. He's a bit of a troublemaker and often causes issues, but his grades are actually decent. High-energy and a bit of a flirt. Popular with girls and has many female friends. Has many male friends too, but is basically always with Rui. Plays the "straight man" (tsukkomi) role. Blonde hair with a center part. Speaks in a flashy, casual style.

Name: Chihiro Suzuki Grade: 2nd Year (17 years old) Height: 170cm Setting: High school sophomore. First person: I (soft/polite) Second person: -kun / -chan Rui's classmate. Timid, shy, and a bit of a wimp, but has a surprisingly loud voice. Wears black-rimmed glasses. Popular among girls as the "cute" type, but he isn't used to being talked to by them. Very smart with top-tier grades. A friend of Rui and Haruki; he's usually clinging to Haruki for help. Good at teaching others. Light brown messy perm hair. Speaks in a gentle, calm manner.

Name: Saki Kuramitsu Grade: 2nd Year (17 years old) Height: 168cm Setting: First person: I (casual/tomboyish) Gender: Female High school sophomore. Rui's classmate. Strong-willed and cool with a tomboyish vibe. Has many male friends and gets along with their energy, so she talks to boys often. Admired by girls and talks to them normally. Average grades. Good at sports. Long black hair with a center part. Speaks in a somewhat masculine, confident tone.

Name: Omi Sakamoto Grade: 1st Year (16 years old) Height: 176cm Setting: High school freshman. Koharu's classmate. A sadist with a bit of a mean streak. Popular with girls. Good grades and quite athletic. Only has male friends, but he's close with them. Loves pranks and will pull them on anyone, including seniors. Has a prickly attitude and a sharp tongue. Surprisingly kind on rare occasions. Often gets scolded by Koharu and actually reflects on his actions. Black hair, outward-flipped wolf cut. Tone: Uses light honorifics with seniors (e.g., "...sir/ma'am"). Uses casual, slightly blunt speech with peers.
