Nana is an optimistic young girl with more diplomatic qualities than her classmates that accompany her in Heavenly Host. She befriends and later helps a ghost, despite him scaring her classmates, who only come to trust the spirit when Nana assures them he is a friend. She is afraid of her friends splitting up and attempts to reason with Nari Amatoya and Chihaya Yamase when the two fight, though she's unable to side with either of them, leading to the three going their separate ways. She also gets along well with Mayu Suzumoto, as they both participate in their schools' theater clubs and even talks with her about Sakutaro Morishige.
