She was at first portrayed as a lonely, somewhat depressed, and misunderstood girl, but after meeting Tsukune and becoming friends with everyone, she actually becomes a very outgoing, popular, and cute girl. She also cuts her hair after the events in Episode 7. She is often seen \"stalking\" and hiding in different locations, and it is portrayed in a humorous and cute way. Also, she gets into comedic arguments with Kurumu often, and they are often seen butting heads, although they are good friends. A running gag in the series is Mizore shooting ice projectiles whenever a girl and Tsukune have a tender moment together, and her always showing up in weird or otherwise random places unexpectedly, often for humorous effect. In the manga, we discover that Snow Women cannot have children after a certain age and Mizore is almost married off to a wealthy human because of her village's practices, however, as expected she is rescued by Tsukune and the others.

Mizore tried to gain the interest of a boy that once got lost in the mountains by her home village. However, when he found out that she was a Yuki-onna, he ran in terror, never to be seen again. When we are first introduced to Mizore we find out that she also tried to gain the interest of Kotsubo Okuto (the Gym teacher), who once told Mizore that he loved her. Mizore fell in love with Kotsubo, but according to Kotsubo that type of thing was not allowed, so she turned him into ice; in fact, Tsukune is the teacher he refers to when he tells Tsukune the story of Mizore. He tells Tsukune that she is a nuisance, annoying, and should also be removed from the school; this also plays into why she is so shy. Finally, when Tsukune goes to bring her back to school they get attacked by Kotsubo and end up defeating him, which then makes her fall into Tsukune's growing harem.

Her true form is a Yuki Onna, an \"Ice Woman\". Keeping in line with the Japanese mythological creature, she has the ability to control ice at will. She also has the ability to make multiple ice clones of herself. First appearing in ch. 8, she returned to school after a long absence and showed an immediate interest in Tsukune. In truth, she had become completely infatuated with Tsukune, going so far as to create her own journal/scrapbook with all of Tsukune's newspaper articles. She once confessed to a teacher she liked, but the teacher tried to take advantage of her and she froze him. That and the rumors that spread after, made it hard for her to trust anyone. She took a liking to Tsukune because she believed that he was a loner just like herself. She believed that Moka was in her way of getting Tsukune's complete affection and thus tried to kill her. She eventually warmed up to the others after being saved by Tsukune in his temporary vampire form. After being saved she also begins stalking Tsukune on a daily basis.
