Fushizen na Girl/Natural ni Koishite
A music critic Haruo Chikada points out in his music column "考えるヒット"(Kangaeru Hitto Considering hits) the antonymy of the two titles and compares the sound of Natural ni Koishite to Scritti Politti. Promotional videos. "Fushizen na Girl", directed by Seki Kazuaki, is based on a single artwork. The video features an elaborate dance performance with the members of Perfume in red dresses. For the first time, Perfume are joined by backup dancers wearing identical wigs and 3D glasses. The video is sparse, featuring only a black infinity cove with a white striped floor. The  backup dancers create additional scenes and visuals by holding up two-tone colour squares. "Natural ni koishite", directed by Kodama Yuichi, features Perfume outside of a Natural Beauty Basic store singing and dancing to the music. The floor of the set is a moving sidewalk, which is used in the dance routines. Midway through, the girls retreat into the store, instantly emerging with arms full of shopping bags. At the end, they run off of the set and out into the parking lot of the movie studio that the video was being filmed at. The clothing for the video was  provided by Natural Beauty Basic and was made available for sale on the website. Four shorter versions of the video were used as commercials: one for each member of Perfume, and one with all three walking down the sidewalk.
