Hobbies: Collecting Ukifune Riku goods
Likes: Ukifune Riku's swimsuit!
Dislikes: Scary people (Becomes weak in the presence of an angry person)

A freshman at Aosaki Academy, a kind-hearted and hardworking girl. She greatly admires Ukifune Riku, because of her, Mito started doing sensui (however, she doesn't realize that Ukifune Riku is actually her coach, Hasemi Riku). Bad at studying and due to not realizing that she's actually pretty good in sensui, is a fact that keeps her from growing as a sensui player.
