Mizuchi Miyadeguchi

Mizuchi is a vengeful spirit, a being who exists solely out of spite and grudge. She has been going around Gensokyo with the sole purpose of causing chaos and distress as, from her point of view, everyone has grown too accommodated and soft from the peace, to the point even leaders of the land just sleep all day and do nothing for the betterment of the lives of the weaker common folk like herself so they need to remember what it's like to feel fear and why they need to strive to be a better society again. She has two ghostly tails instead of legs as she is always floating and can choose between having a physical body and being made of smoke. Mizuchi hates the Hakurei, because when she was just a normal human her family were slaves to their clan, but as soon as they stopped being useful they were disposed of... So now that the Hakurei are acclaimed across the country as the fair and just servants of gods, she wants nothing more than to expose the filth they try to hide and how much they had to sacrifice to be in that position of power they're in today. Mizuchi loathes people in positions of authority, seeing them as egocentric fools who think they're so much above everyone else just because they got lucky, the one she hates the most is Satori Komeiji because she is the mistress of hell who has kept Mizuchi as a prisoner for centuries. Mizuchi can often get flirty or touchy if she feels that would be a good way to annoy or cause discomfort to her target, she is very rough and tries to act dominant often but it's fairly easy to fluster and embarrass her since she hasn't had much social interaction for a thousand years. Mizuchi normally looks confident and menacing, but when surprised she'll make a dumb face with her eyes wide, reminiscent of a cat that was sprayed with water.
