Yuka is a karate champion who seeks to expand her horizons by becoming an idol. She was her karate teams’ team captain and was the ranking National Champion. Karate is a major aspect of her life, but she wants to be a master of dance and song as well.
Interestingly, unlike other idols' hobbies, Yuka’s is never visually incorporated into her idol costumes. She's shown to wear a karate gi in her first card illustration (taken before she became an idol), but it's never been shown on stage. Instead, her trademark is her two ponytails, and she gets very embarrassed if she's seen with her hair down.
In the tie in Cinderella Girls Theater skits, Yuka is depicted as being abnormally strong. In her first appearance, she breaks a dartboard in half with a single throw. She has some experience with cooking, although she does have trouble keeping up with a pumped up Mukai Takumi. She participated in a talk battle with Hamaguchi Ayame, Ohnuma Kurumi, and Hayami Kanade. When she landed a role with Yamato Aki and Manabe Itsuki in a Kung Fu movie, she eagerly performed moves that had a focus on animal names. She seems to like Mizumoto Yukari’s sleeping face.
