Puella Magi - Yuki

Yuki is a quiet and mysterious Majou Shoujo who has made a contract with Kyubey a long time ago. Her specialty is the element of Ice and she fights using Kunai she hides in her long sleeves.

She has appeared before Amane many times during Witch battles and she seems to be an ally, though her cold personality could be the result of a difficult past. She is aware of what happens to Magical Girls if their Soul Gem becomes corrupted and she is the one who revealed that truth to Amane.
