Also known as the "Siren of Watasumi Island", she can only be found at night in the Watatsumi waters. Very few know of Kokomi's siren form. When in this form, her purple irises darken, both her teeth and nails sharpen, and pink scales appear all across her body. The most notable change is the fish tail. When Kokomi shifts back, she will not recall what she has done in her Siren form, and return to her usual calm, bubbly personality and her duties as the Divine Priestess of Watatsumi Island.
