Anime render of Luca
Luca has drooping raspberry eyes and yellow hair with her bangs mostly brushed back, except for one that curls up. Her puffy pigtails have blue spots on them and she wears a swirled, light blue and pastel pink shell for a hat. Her wings are pale colored.
Luca wears an orange bikini top to accent the pale cape-like cloth hanging from her waist. Her mermaid tail is pale lilac with a pink bow towards the bottom. She also wears a cyan bead necklace and a purple cloth draped around her arms.
- Luca's motif might be based around seashells, due to her seashell-shaped hat. Seashells are small protective layers mostly associated with marine mollusks (clams, hermit crabs). Empty shells can also be found washed ashore on a beach.
