イチズレシピ (Ichizu Recipe) is the opening theme for the 2015 anime adaptation Shomin Sample (俺がお嬢様学校に「庶民サンプル」としてゲッツされた件), performed by the Japanese idol group Idol College (アイドルカレッジ). The track joined the maimai arcade lineup during the PiNK PLUS edition in July 2016 and was later removed from the catalog in December 2018, making it a legacy song unavailable on current cabinets. The title fuses "ichizu" (一途, single-minded devotion) with "recipe," a playful match for the anime's premise, a commoner boy forcibly enrolled at an elite all-girls school to serve as a "sample" of ordinary life. At 170 BPM, the song's bright, driving pop arrangement mirrors the series' energetic comedy. A distinctive piece of production trivia: the word "ゲッツ" (gettsu) in the anime's subtitle originates from comedian Dandy Sakano's catchphrase gag. Sakano was officially credited as "Gettsu! Supervisor" for the show, made a cameo appearance in episode 10, and appeared in the music video for this very song. The anime's opening sequence, which briefly features Sakano striking his pose atop a crescent moon, also serves as the in-game play background.
