A high school girl, blonde, D-cup. A boyish beauty who serves as the de facto leader of the Camping Club. She is recognized by herself and others as being mannish and aggressive, and is so strong in a fight that she can handle two or three average men.

Because of this, combined with her appearance, she has a poor reputation among some teachers and students at school, starting with Miku. However, she is not used to being treated as a girl.

Ever since their first encounter, she has been wary of Yamamichi and picks fights with him at every opportunity, but she is also aware that he was the first person to treat her like a girl, leading to complex feelings.
As a result, when Yamamichi makes a move on her, it's always when he's drunk, and she finds herself saying things like "Don't touch me when you're drunk," showing signs that she's not entirely opposed to his advances.

A little devil girl with high feminine energy. E-cup.
She often toys with people using her mature demeanor, and knowing about Haruki's suspicious relationship, she lets it continue because she finds it amusing.
She loves cute clothes and often wears "Jirai-kei" fashion on her days off. She's a bold one who even participates in camping wearing a frilly skirt.

A high school girl, same age as Haruki and the others. E-cup.
A mysterious, gentle-natured girl.
She loves dogs and always dotes on her beloved dog, Poppy.
She seems spacey at first glance, but sometimes a switch flips and she lets out a sharp remark.
It seems she is hiding an unexpected side to her nature.

A pure-hearted maiden, full of energy.
Among the Camping Club members, she shows the most cooperative attitude towards the advisor, Kensuke.
And for good reason—she actually fell for Kensuke from the day they met by chance while camping...
Her catchphrase ending with "~ssu!" is her charm point.
