安城 鳴子

Naruko is a childhood friend of Jinta and Menma. While she displays a cold attitude towards Jinta, she is secretly concerned for him. She is perhaps the closest to him at present and is enrolled the same school (although Jinta stopped attending school). Chiriko comments that Naruko has not changed over the years: she is still easily persuaded by everyone around her. Naruko seems to be popular in high school and gets along well with girls that Chiriko deems "sluts." However, she works at a video game store and has a large collection of manga and video games herself.
