Movie
Description
Nao Yokoyama is a 17-year-old Osaka native whose vibrant Kansai dialect and impulsive cheerfulness reflect her hometown's spirit. Her physical presence includes a 159 cm height, 46 kg weight, and 84-57-83 cm measurements, complemented by dark brown hair styled in a high left-side ponytail secured with a dark blue star-patterned scrunchie and distinctive pale purple eyes. Typical casual wear features a zebra-print singlet layered under a black "harapeko" (meaning "extremely hungry") t-shirt, bright yellow leggings, a star-shaped necklace, and a zebra-patterned scrunchie.

Her personality blends exceptional physical stamina with chronic forgetfulness, causing missed lessons and abrupt memory lapses. This forgetfulness extends to clumsiness, frequently depicted in cards where she drops objects like microphones mid-performance. As a self-proclaimed "harapeko," she constantly expresses hunger, often shown eating. Nao thrives on chatting with friends and relaxing in public baths or hot springs, maintaining close ties with Takane Shijou, Arisa Matsuda, and Minako Satake—though she visibly bristles at Arisa's data-collecting habits. Mornings challenge her, prompting wishes for a reliable wake-up call, and her soccer-athlete brother Kei once gave irrelevant goalkeeping advice during a match.

Within Million Live!'s "39 Project," she debuted as a Dance-type idol with a periwinkle or light blue image color. Fan culture nicknames her "Naonao" and amplifies her clumsiness as a signature gag, illustrating thrown objects accidentally hitting others.

In the movie narrative, she joins as one of seven backup dancers from an idol training school, assisting 765 Production's arena concert preparations. She participates in Wakasa Inn training camps and miniconcert performances, engaging in group rehearsals and interactions. While the storyline centers on Kana Yabuki, Nao remains part of the backup ensemble during the "M@STERPIECE" concert. Her connection to the broader idol universe culminates in a post-credits cameo alongside other Million Live! characters.
