She introduces herself as Satella when she and Subaru met during the first timeline before introducing herself by her real name when she got her insignia back.

She is indifferent to her own appearance, leaving Puck to take care of her clothes and hair.

She sometimes acts like a child and is unacquainted with the world as she used to live in the woods with other Elves, though despite this she still works hard to become a ruler.
