アナ

Anna is a half-elf attendant who has served the royal family for successive generations of kings. She is like a foster parent of Schlain and Sue, and she serves as a maid and guard for them alongside her colleague Kleava. As a first-class magic-user, she is an attendant who will fight to protect royalty in time of need.
