Formerly a member of the Northern Jaegers and known by her title, "Purple Lightning," Sara is currently an A-Rank bracer. She's both beautiful and a skilled combatant, though she can be a bit crass and slovenly at times.
She spent some time serving as an instructor at Thors Military Academy, both to Towa and Crow's group of ARCUS test members, and as the homeroom teacher to Class VII.
After the war, she retired from her brief teaching career and returned to her work as a bracer.
Currently, she's partnered up with the rookie bracer, Fie. Together with Toval and the other bracers left in Erebonia, they're investigating the unrest bubbling behind the scenes in the empire.
