Ноно

Nono is one of Mii's closest friends, though its unclear whether she would distinguish her as her like that. It is likely due to her association with the game that the anime links it as such. Nono is a shrine maiden slightly older than Mii with blue hair. She is shy and seems to care deeply about her grandfather, who is very strict when it comes to training, especially heathen holidays like Christmas.
