ヨミビトシラズ (yomibito_shirazu) is an original song by Limonène, a unit formed by composer kamome sano (サノカモメ) and vocalist Haruka Tsukishima (月島春果, who also performs as mikanzil). The track serves as the narrative climax of the 7sRef Area (7sRefちほー) in maimai DX UNiVERSE, appearing after the area's Perfect Challenge, the first time the series structured an unlock this way. The title is a katakana rendering of 詠み人知らず, a classical Japanese phrase meaning "author unknown," traditionally used in poetry anthologies when the poet's name was lost. This theme of fading authorship and ephemeral memory runs through the lyrics, which dwell on impermanence, forgotten names, and the desire to suspend a fleeting moment in time. The music video by はなけん weaves in imagery from kamome sano's earlier song 線香花火 (senkou hanabi), including a brief flash of its original 2012 video. Musically, the 188 BPM composition embeds a five-note motif, so-do-re-mi-fa-mi-re-do, that nods to Believe the Rainbow, kamome sano's previous contribution to the maimai PANDORA BOXXX campaign. Song and video together form the emotional and narrative terminus of the 7sRef storyline, a tale of travelers gathering memory fragments before a white tower.
