A little about Mizuki: She has amnesia and doesnt remember anything before waking up in a mental hospital. She has two sides to her, one side is her innocent side when she is so adorable and cute and the other is her psychotic side when she can severely injure and even kill someone, she gets like this when someone she doesnt know touches her, she remembers something from her past or you take something she has claimed as her away from her.
I hope you like her ^^
