Yukari Sendo

Yukari Sendō is a self-proclaimed genius and the smartest student at Yōkai Academy, despite being the youngest. She is a Witch and wears a typical witch costume (consisting of a hat and cape), which is considered by some students to be a violation of the school dress code. As a witch, she has problems with her classmates discriminating against her (in the series, witches are viewed as "border beings", those that are something between humans and the supernatural, as it is impossible to tell their difference by appearance alone). Despite ranking #1 on the examinations, she was a lonely prankster before meeting Tsukune and Moka.

She initially hated Tsukune, claiming that she had fallen in love with Moka and used her magical powers to try to drive them apart. However, after both Tsukune and Moka save her from bullying classmates, she falls for him too. Her obsession with both has driven her to try to create a three-way relationship between them (though shortly after Fang Fang's introduction, she attempted to create a larger relationship involving Kurumu and Mizore as well.) Yukari has, on occasion, developed some bizarre items, often leading to funny results or farfetched situations.
