Name: Zeilyph; goes by Mira
Race: Ghoul
Age: 48 looks 24 and sensitive about her age.
Bio: She acted as Ystmurra's mentor for their entirety of being together, starting when Ystmurra was age 1 (note that they never age. That's how many years they've lived as a ghoul) Zeilyph taught Ystmurra about how to adapt to being a ghoul. They've grown so close together that they're almost mother and son.
Zeilyph, however, did not like to make contact with humans, for the moment that they realize she is a ghoul, she would be banished in shame. She thought it'd be better, if anything, than 'to go in with shame than to walk out feeling that horrible feeling again.' She heavily discouraged Ystmurra on going to the university. But Ystmurra would not budge, so in the end she let him.
However, she didn't quite want to let him go just yet...
There is a hidden portion of history about her. Once, an entire town tried to kill her for being a ghoul. They were about to kill Ystmurra. That's when she lost it. She turned into a ghoul, but she was so overwhelmed by anger that she killed everyone in the city. The city is now abandoned with no witnesses left live. The town is blanketed in snow forever.
Gender: Female
Magic: Ice. She breathes cool air as a human, but does not summon any. That happens when she turns into a ghoul. This is indicated by her eyes shining brighter than usual.
Luggage: a fake application too real to differentiate from a real one and a pack of strange needles.
Appearance: as a normal, calm human, she is nice. She has noticably bright blue eyes.

When she's angry at Ystmurra or someone making fun of her age.

As a ghoul.

She looks just like Ystmurra in ghoul form, but instead of fire, she has ice swirling around in her skull and has shining blue eyes.
Why did you come to this university?: to watch over Ystmurra.
Personality: will treat younger kids like a teacher, Ystmurra like a son, and the other teachers like good friends. But anyone who finds out about either Ystmurra or herself being a ghoul who decide to act against them will feel the wrath of Zeilyph.
Other: I imagine one of the later incidents of the school would be that everyone finds out about their true natures and will rise up against them... To attempt to reenact the blanketing of the abandoned snow town. Of course, the heroes will win, but rollz with me.
So whadd'ya think?
