Hina (Hirona Nagahama / Nagahama Hina) Date of birth/age: June 19, 2008. 2nd-year high school, 16 years old Birthplace/height: Tokyo / 160 cm Personality/characteristics: The "O-Hina-sama" with overwhelming self-esteem. At first glance she seems like a calm, refined young lady, but she became the explosive protagonist of the Halong arc with her overly strong-willed, positive personality, such as giving pep talks to timid boys like "Make your heart macho too." Hairstyle/hair color: Long black hair. Her trademark is a heavy, straight-cut fringe neatly trimmed above her eyes. Arrangement/appearance: During the trip she showed adorable hairstyles just like a doll or princess, such as high twin tails and half-twins. Her refined, elegant young-lady look is her defining feature. She is interested in Monta.

Mei (Mei Amamiya / Amamiya Mei) Date of birth/age: June 14, 2007. 3rd-year high school, 17 years old Birthplace/height: Fukuoka Prefecture / 159 cm Personality/characteristics: A classic idol-type beauty overflowing with a sense of transparency. She seems calm and gentle, but she is very honest and straightforward when it comes to love. She has a sincere and direct personality, putting her feelings into words clearly. Hairstyle/hair color: Lustrous dark brown long hair. Styling/appearance: Her basic style is softly waved hair worn down. With the visual of a classic idol-type beauty, she has a natural, neat, and transparent look that is extremely popular with boys and makes them want to protect her.

Serina (Serina Sato / Sato Serina) Age: 1st-year high school Birthplace: Chiba Prefecture Personality/characteristics: An exclusive model for the popular gyaru magazine "egg." Her appearance is that of a flashy, trendy gyaru, but inside she is very pure, befitting the youngest member. She also has a shy side, and her pure way of trying her best at love makes her a character you want to root for. Hairstyle/hair color: Gorgeous long curled hair. Styling/appearance: As expected of an exclusive model for the gyaru magazine "egg," she is the most conspicuous trendy girl, looking great in gorgeous hairstyles, large accessories, and the current gyaru school uniform styling.

Oga (Oga / Oga) Date of birth/age: March 24, 2009. 2nd-year high school, 16 years old Birthplace/height: Tokyo / 176 cm Personality/characteristics: A prince type with a sweet, well-defined, almost half-Japanese look. He is gentle and gentlemanly, but he also has a smart, manly side, always treating the person he likes specially. Hairstyle/hair color: Mushroom-based hairstyle. Styling/appearance: A refreshing Korean-style look with the bangs down and slightly revealing the eyes. With his well-defined, almost half-Japanese features, a slim suit-style uniform looks great on him, making him truly worthy of being called a "prince."

Monta (MONTA / Monta) Date of birth/age: July 6, 2007. 3rd-year high school, 17 years old Birthplace/height: Tokyo Personality/characteristics: A highly unique type whose special skill is vocal percussion (beatboxing). He seems like a cheerful, sociable jokester, but he actually has a passionate personality full of chivalry and cares about those around him more than anyone. Hairstyle/hair color: Spiky black hair with standout individuality. Styling/appearance: His piercings, especially around the ears, are very striking, and his street-style, B-boy/rapper-inspired fashionable and edgy look attracted a lot of attention even in the studio.

Rui (Rui Kurata / Kurata Rui) Date of birth/age: March 24, 2008. 3rd-year high school, 17 years old Birthplace/height: Nagano Prefecture / 174 cm Personality/characteristics: The central figure in this turbulent love story. He is shy and somewhat susceptible to being pushed around, but amid the intense rivalry over Ohina-sama (Hina), his clumsy yet desperate efforts to break out of his shell and appeal with his feelings greatly excited the studio. Hairstyle/hair color: Neat black short hair. Styling/appearance: Natural hair with the bangs slightly parted or casually textured. With a not-too-flashy, classically handsome presence, he wears his uniform simply and neatly, giving off a refreshing vibe typical of a male high school student.
