Ulti is a young woman of relatively tall height,[3] with a light complexion. Her hair reaches near her mid-back and forms rounded locks mainly blue in coloration, but with thin, pink-colored streaks running through (plus a single white one over her left eye). Blunt bangs fall on her forehead, split near the left, and an ahoge stands up on her head. Characteristically (as with many of her crewmates), Ulti has horns: a sharp, upward-curving pair emerging from the sides of her head, white in color.
