The song that claimed maimai's record for longest Japanese title at launch, 38 characters' worth, is a solo character track for Komibukuro Nagi (小仏 凪), a member of the Irodorimidori (イロドリミドリ) multimedia franchise, voiced by Sakura Kaoru (佐倉 薫). Its verbose, academic-style title translates roughly to "A Study Concerning One Reality That Evoked the Fantastical Worldview Within Me and Its Manifestation," a framing that matches the eccentric, intellectually theatrical persona Nagi projects within the Irodorimidori lore. Categorized under the オンゲキ＆CHUNITHM (ONGEKI & CHUNITHM) genre in maimai, the track arrived during the MURASAKi version on February 21, 2017, and runs at a brisk 175 BPM. The title was so unwieldy that official Sega notices and in-game menus regularly abbreviated it as "私の中の…" ("Within Me…") or "私の中の(以下略)" ("Within Me (hereinafter abbreviated)"). Though it held the title-length crown at release, it was later overtaken by "Bad Apple!! feat.nomico (Tetsuya Komuro Remix)" and, more recently, by "False Amber (from the Black Bazaar, Or by A Kervan Trader from the Lands Afar, Or Buried Beneath the Shifting Sands That Lead Everywhere but Nowhere)." The song's MASTER chart, designed by 玉子豆腐 (Tamagodoufu), and EXPERT chart by Moon Strix have undergone level adjustments across multiple maimai versions, reflecting how the game's difficulty calibration has evolved since its MURASAKi-era debut.
