A transfer student at Tomobiki High School, Class 2-4. She is a girl, but because her father says the successor to the Hamachaya must be a man, he raises Ryūnosuke as a boy and insists that she is one.
When Ryūnosuke first appears, she and her father are shouting at the sea, blaming it for the fact that the Hamachaya receives no customers except during the summer. They fight so much that they accidentally destroy the Hamachaya, so they move into and operate the Tomobiki school store in order to raise money to rebuild it.
Ryūnosuke frequently fights her father not because of their martial arts-style training or for the joy of it, but simply because they have grown accustomed to fighting over the years.
She is at heart a kind and honest person and wishes no harm on anyone other than her father; her gentlemanly acts are thus as natural. She hates being touched by men and repeatedly denied them, and even the idea of being with one disgusts her. She is solely dedicated to regaining her femininity, so she only has women in her sights. Her first love was her elementary school teacher, whom she later realizes was a woman.
Because her eccentric father has raised her as a boy, Ryūnosuke behaves a lot like one, despite in fact being a girl, and hating being treated like a boy. She would love nothing more than to let her feminine side show, but her father interferes in every attempt she makes. When her father enrolled her in Tomobiki as a boy, he refused to buy her a sailor uniform, which he had promised her if she can beat him in a fight (which she is yet to accomplish).
Her warped upbringing also made her a bit naïve, susceptible to being suckered into or convinced of pretty much anything.
Ryūnosuke is usually wearing a gakuran like her male peers and a sarashi. Wanting nothing more than to be more feminine, she is saving up money to buy a bra and sailor suit, in the belief that bras cost several thousand yen (most probably thanks to her father). At one point, Shinobu Miyake promised to buy her a bra if she posed as her boyfriend in order to scare away gang leader Sōban; but as usual, Ryūnosuke's father interfered.
