Being an idol seems kinda fun, so I'm gonna do my best~!
— Yokoyama Nao, Online Profile

Yokoyama Nao (横山奈緒?) is a new idol introduced in THE iDOLM@STER: Million Live!. She is voiced by Watanabe Yui (渡部優衣).


A cheerful and energetic girl from Osaka who speaks in Kansai dialect, Nao is what is considered to be a stereotypical Osakan person; like always keeping some candy for herself; though she not good with tsukomi in a boke & tsukomi routine. Nao is not a very bright girl, preferring to take action instead of thinking things over, and also has great confident in her own stamina.

She is very forgetful, it isn't unusual to see her losing microphone during a performance or a note on which she wrote the schedule and often forgetting that she has a lesson, and sometimes forgets even what she just said a few minutes ago.

Nao is also a harapeko (a character who can eat a lot and eat often, like Takane), evident by the fact that she wears a shirt that has harapeko written on it and a few of her cards depict her eating something, and she also often complains that she's hungry.



  • According to a tweet from her seiyuu, Nao's image color is periwinkle or light blue.
  • She has an older brother who is a soccer athlete, as revealed in the soccer event when she asks for some advice from said brother. Unfortunately, in that event, she ends up playing the goalkeeper, rendering his advice useless.
  • She's nicknamed “Naonao” by fans.
  • She's not good at waking up early and wishes that "someone" would give her a morning call.
