Koyomi Mishima | 三島暦 | My Dress-Up Darling v1

Source: My Dress-Up Darling (Sono Bisque Doll wa Koi wo Suru)

Koyomi Mishima is the "cool-headed and beautiful" counterpart to Shion Nikaidou within the Argeous game. While Shion has a blue/ice theme, Koyomi is often associated with a more sophisticated, dark-palette aesthetic. This cosplay represents Marin's transition into a more "mature" and "refined" look compared to her usual high-energy self.
