Shizuru Viola

シズル・ヴィオーラ, Charming Amethyst
3 of the Five Columns known as the Charming Amethyst. Her interest in Natsuki seen in the original MaiHiME seems to be upgraded in this series to an actual relationship. She permanently resides with her in the Principal building when shes not on missions for Garderobe. Shizuru is from Wind Bloom and she was classmates and rivals with Haruka. Her element is a naginata doubleedged sword whose blades can extend in a whiplike fashion much like her naginata did in MaiHiME. Her reason for fighting is to protect her most precious person.
