Nana is the second princess of the planet Deviluke. She has two sisters: a twin-Momo and an older sister-Lala. She, like her sister Momo, has a fairy power, but unlike Momo who can communicate with plants; Nana can communicate with animals. Nana is a tsundere which is shown by calling Rito an idiot and denying her love towards him; but she is also childish as she is boasts on how she is better than Momo, and she didn't know what sex was until Mea told her. Although she doesn't show as much affection towards Rito as the other girls do, has on a couple of occasions tried to sleep in Rito's bed with and starts having more affectionate feelings towards him as the series progresses. She is especially self conscious about her chest as she is flat unlike her two sisters and everyone else in the series.
