Сендо Юкарі

Yukari Sendo is the smartest student at Yokai Academy, and the youngest at age 11 (later 12). She is a witch who dons a typical witch costume (consisting of a hat and cape), which is considered by some students to be a violation of the school rules, and frequently ends her sentences with "desu", which roughly translates to "it is". However, it can also have the effect of raising the politeness of one's speech. As a witch, she has problems with her classmates discriminating against her (according to Kurumu, witches are viewed as "Beings of the Borderline", 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 has fallen in love with Moka, and uses 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, and her obsession with both has driven her to try to create a three-way relationship between them. Despite her genius IQ, Yukari is very childish in nature, and is often indecisive on whether or not she either loves Tsukune or Moka more than the other. Though it seems that despite her young age, Yukari might be bisexual, as she still has interest in Tsukune as well as Moka.
