Rami Shiira from Manga series Kirei ni Shitemoraemasuka. To go with the fish theme, Shiira is the Japanese name for Mahi-Mahi.

Trigger: Shiira Rami

Description: glasses, greyish brown hair, blue-grey eyes, star earrrings

Kind of a tricky character to prompt, the colors are kinda all over the place because the base data is all greyscale. I'm happy to even have found a color reference for her at all. Wears a variety of culturally appropriated ethnic outfits, whose names fail me for prompting purposes, too.
