Yu is an above-average height young woman of fair skin and curvaceous frame. She has magenta eyes with white pupils and long eyelashes. She has voluminous, creamy blonde hair reaching down to her waist, with two shorter strands tightly curled to frame her face, parted slightly to her right. Yu is an ambitious and egotistical woman who enjoys the attention that being a hero gives her and doesn't feel any shame over taking that fame from another hero while basking in the glory.
