Shirayuki, Mizore

白雪みぞれ

Mizore Shirayuki is a yuki-onna who shares a homeroom class with Tsukune and Moka, and is often seen with a lollipop in her mouth. Her attire includes a white wide-necked sweater with blue sleeves worn over a black tank top, a short yellow plaid skirt that is part of the Yokai Academy girls' uniform, pink and violet stockings (with her right stocking slightly longer than her left), and a belt wrapped around her left thigh.
Mizore returns to school following a delayed absence and is initially depicted as a lonely, somewhat depressed, and misunderstood girl. She develops an infatuation with Tsukune, going so far as to create a personal journal/scrapbook containing all of his newspaper articles.
In the past, she confessed her love to a teacher until he began taking advantage of her, causing her to freeze him as a result. With the incident and rumors spreading about her, Mizore found it difficult to trust anyone, but she took a liking to Tsukune, believing he was just as miserable as she was. She eventually regains her sense of trust after Tsukune intervenes when the same teacher returns to kill her. Unfortunately, this leads Mizore to stalk Tsukune on a daily basis (from around 340 spying locations, according to her). She initially has long hair in her debut appearances, but cuts it short after the incident is cleared. Later in the second serialization, Mizore decides that even if Tsukune does not fall in love with her, she will follow him forever.
A running gag in the series is that Mizore always appears unexpectedly in the oddest locations (under tables, behind doors, the ceiling, bushes, and even in the bathroom), and freezes any girl to disrupt any sort of tender moment Tsukune is having with the latter.
Consistent with her kind, Mizore has the ability to control snow and ice at will, and while doing so, shapes claws of ice around her hands (her hair becomes ice on rare occasions). She can also make almost perfect copies (if a bit fragile) of herself and others with it as well, each capable of independent thought. She is also very sensitive to flames, a common weakness for ice-affiliated creatures, which was shown in one episode of the anime when she got her hand burned while preparing curry, freezing the dish on instinct as a result.
