Mizino was created for a couple who couldn't have children, no matter how hard they tried, and they decided if a human child was out of the question, they'd be happy with anything. And so here came Mizi. She wasn't made specifically for any household chores or work, so she's able to enjoy life to the fullest, though still helping around the house. She attends school normally, loved by her classmates for all the help she gives. She loves her "parents" more than anything in the world and often cooks for them as a way to show appreciation.
Mizino is part of the semi-open species "Udroid," created by Shimmer50 and Hyanna-Natsu on dA! https://www.deviantart.com/udroid Special aspects of her design are NOT optional. She doesn't bleed or need to eat. She's simply having a splendid time.
She loves a variety of things, especially things that make people happy.
