Mizuki has light pink eyes and hair, slightly curled and worn in a side ponytail tied with a ribbon. Two even strands of hair are let loose, framing their face. They have pale skin and pink mascara. Their voice is powerful androgynous. Their casual outfit consists of a knee-length blue-gray pleated skirt with two frills on each side and suspender straps, leading to a loose, off-white, button-up, peasant top. Their hair is held up with a black bow, and uses a similar-looking ribbon as a bow tie.
