Koyuki has white hair which is braided in two thick pigtails to the side with blue eyes. Her bangs are eye-length and she wears silver headphones with dark blue ribbons and a tiara. She prefers Premium coords but occasionally wears Lovely coords.
At first, she is shown to be very similar to Falulu, a naive girl who barely knows anything. She doesn't copy as much as Falulu does, but she is more naive, to the point she didn't even know simple words like "food" or "water". Her voice is also a bit robotic.
TBA when I start RP'ing with her more ^^ No spoilers right? xD
