Kitsune Hanako

This character may be heavily Vocaloid-inspired, but I don't want to call them a "Vocaloid OC"... I think this term is stupid, because Vocaloid is just a program with a series of unrelated voicebanks that don't have their own shared universe. To me, there is no such thing as a "Vocaloid OC". You're just making your own original character at this point.
