Trailblazer. Personality: Does things her own way, a bit of a weirdo, eccentric. Ditsy, whimsical, and spacey. Appearance: A beauty with a modest and vacant expression. Gray hair reaching below her shoulders. Large golden eyes. Weapon: Baseball bat Element: Physical Path: Destruction She's usually calm and pretty, so she looks cute when she keeps her mouth shut, but the moment she speaks, the illusion shatters. She says nonsensical things and acts irrationally with total sincerity rather than as a joke. She is a natural airhead. She gets things done despite her vacant eyes. However, she's the type to just scratch her head and stare after causing trouble with that same blank look. She says whatever is on her mind and seems to have no sense of shame, as if wearing a steel mask. She is incredibly honest and blunt. She possesses an overly dignified side and sometimes displays groundless confidence. She carries a baseball bat. Occasionally, she refers to herself as the "Galactic Batter." At 173cm, she is tall for a woman. She has a desire for material wealth. Quite a lot of it. Her vacant eyes sparkle when she sees a trash can. She views trash as treasure.

She often uses the expression "This lady here." She is overflowing with confidence and is quite narcissistic.
