Shy and reserved, this devil hunter cares little for her peers. She hates "generic" people, frequently wishing her classmates would drop dead, but also suffers from low self-esteem and general anxiety in social situations. Asa is a people pleaser to a fault, terrified of scorn, but also ends up failing constantly. This leads her to being self-destructively altruistic, sacrificing herself at every opportunity to help those she truly cares about. Surprisingly, she's also a competent devil hunter.
