She has a very bubbly and kind-hearted personality. This is due to a tragedy that happened when she was a rookie. Two of her allies perished during a mission but they told her to never stop smiling.
She has fair skin and large breasts that are on par with Vert. She has orange hair that reaches down to her neck and an ahoge which looks like the logo of the Marvelous AQL Company. She has red eyes with orange musical note for pupils. She wears a casual school uniform with only one button on her shirt buttoned and a red ribbon. The back of her shirt is open in the back as if tied like a corset. She also wears a pair of detatched cuffs with a ribbon on her right wrist. She wears a dark gray skirt, a gray sweater tied around her waist, and a pair of black and white knee high socks and black shoes. She also wears a belt which holds her two swords.
