The reason for the change in her personality is because her kind were summoned by the Senshi Civilization to pilot the Sacred Mechanoids, and her time of weakness shows that her people have not yet fully stabilized in this world. Initially she admires Kenshi's wilderness skills, but grows to develop a romantic interest in him, even to go as far as to kiss him (but he was unconscious and did not know he was kissed) and then confess her feelings to him (even her own father suggests she should marry him).
When not dealing with school-related tasks at the academy in the Holy land, she is nearly always accompanied by two male retainers and when she is piloting a Sacred Mechanoid, she has two female Sacred Mechamaster retainers for back-up. Her Sacred Mechanoid is green and brown armed with a crossbow, and has the ability to generate the Dark Elf Field, a powerful force field that can repel any enemy that comes in range. However, using the field is extremely taxing on the user's body. She is also a very skilled fighter in and out of a Sacred Mechanoid (when its not her time of weakness when her personality changes that is), fighting off bandits like Cordyline, Lan and barely winning a Sacred Mechanoid battle with Doll thanks to her Dark Elf Field, but she thought it was pathetic of her to use the field to win.
