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.
Age: 12
Height: "5'1 (155cm)
Nicknames: Poppy
Character Item: Tomato
More Info: Hanako is a cheerful, but mischevious girl. She loves jesters and desperately wants them to become mainstream again, so she's secretly orchestrating their comeback in her spare time (or at least trying to). Her tail is actually a bag full of tomatoes. When she gets mad at someone, she throws tomatoes at them. Hanako's day-to-day activities include stealing food (usually tomatoes), performing in public spaces, pranking strangers and making mediocre music on her laptop. Despite her incompetence, she's very passionate about what she does. I might make an UTAU voicebank of her sometime in the future.
Trivia:
The name Hanako was also an early name for the Vocaloid Meiko. Once I heard that fact, I saved the name for a future character of mine, and this weird bootleg Vocaloid jester was lucky enough to be the one who ended up with it.
The nickname Poppy is based on the Poppy Bros. enemies from Kirby.
I once came up with the fact that she's three souls in one body, as opposed to Kagamine Rin and Len being one soul in two bodies. That means her character number is actually 9 but the three souls multiplied that by 3, turning it into the 27 that's visible on her arm. To be ridiculously precise, the souls that inhabit her belonged to a 3000 year old kitsune, a jester from the middle ages, and a musician who had a criminal double life. These thoughts popped into my head long after I made the artworks for this page though, so most of that didn't carry over to her design... Do with that what you will.
