Hakase means professor. This is the only name of her that we know, so that shall be what we will refer to her as. Hakase is an eight-year-old genius that still acts her age. She created Nano, her robot caretaker. She is very immature however and loves to eat snacks. She has little self-control, although she will tell you she does. However, she is very nice, just very immature. She isn't exactly snobby, but she may whine to get her way. She is probably the cutest character on the show and will always play around and act silly.
