In her daily life as a D-class, she lives quietly and is so bad at arguing that she just takes whatever is thrown at her. She usually jumps straight into a fight, but after drinking holy water, she's in a dilemma because she might actually kill someone. Because of this, she secretly enjoys getting attention.
