A clever, mischievous girl who's the daughter of a well-off family, Yuki originally enrolled into Ninjutsu Academy to learn some manners and discipline. In the manga she's rather cool and aloof, but her portrayal is a bit different in the anime where she comes across as lively, bright and energetic. She loves playing pranks and often springs them on Rantarou and his friends.

Usually seen together with her friend Tomomi in the manga, and as a trio with Oshige in the anime.
