Fuyuko Kourine

Fuyuko Kourine is a 17-year-old vocaloid girl who has a few quirks. She ALWAYS wears the same outfit with the same scarf, with her hair in the same style. Despite her weird behavior, she is smarter than most teachers and has already graduated college. People think she falls in love with everyone she meets due to the fact that she blushes every time someone speaks to her, but she doesn't, she only blushes because she gets embarrassed talking to people she doesn't know. Although, around other Vocaloids, UTAUs, and other friends, she can be exremely self centered.

She has an extremely odd catchprase ("Contaminate the crime scene!"). People think something happened to her involving a crime. Nobody knows if she commited one or witnessed one.

Her favorite song is Fukkireta/Micheivious Function.
