Mayuko Chigasaki is the main character of the anime NieA_7. She's introverted and quiet (but not the extent that, say, Lain, is. She lives in a small room in the Enohana bath house, and attends the Ipponmatsu cram school. NieA, an alien, lives in her closet. The relationship between the two of them is... interesting. She has to work several jobs in order to pay for cram school and satisfy NieA's seemingly bottomless appetite.
