Kokomi, of average height, has long pale salmon pink hair and light indigo eyes, pupil-less with a large white highlight atop the iris. Her hair is styled in a high ponytail. Adorned in an off-the-shoulder navy-blue kimono-like coat with paler blue swirling accents resembling waves at the tamoto sleeves' bottom, she pairs it with a low-cut white-lilac bodysuit and scalloped-hem shorts. A indigo bow with her Hydro Vision, flanked by two purple ribbons, graces her chest. She wears geta sandals.
