A 16-year-old bracer-in-training and the series protagonist. Estelle's got that infectious, never-quit energy—the kind of person who charges headfirst at whatever catches her attention, sometimes without thinking it through. She's a tomboy through and through, though her naivety can get her into trouble.
Her father Cassius brought home a boy named Joshua when Estelle was eleven, and he's basically become her adopted brother since then. Cassius trained her well in martial arts, and she's become genuinely skilled with a bo staff—which is actually longer than she is, but she handles it like it's nothing. As for orbal arts, she's got no elemental restrictions, so she can pull from a wider arsenal than most bracers her age.
What fans often note is that her biggest advantage might be her personality. She's relentless in a way that matters. Her father is ranked "S" class—one of only four bracers at that level worldwide—but Estelle knows almost nothing about his past, which is its own mystery hanging over the story.
