ガラハド

"I've got work to do. Tea time can come later." Based on Galahad, who in Arthurian legend, is a knight of King Arthur's Round Table and one of the three achievers of the Holy Grail. A knight of the Round Table who, alongside with Gawain, serves Arthur directly. She is a giant lump of loyalty, always in control of herself. Her characteristic of executing her missions without care for personal harm makes her (in a different way from Gawain) a knight amongst knights. She wields a magical ice sword. Galahad's surroundings are always cool. However, she herself tends to get heated up easily. [From English official site]
