maiム・maiム feat.週刊少年マガジン is a maimai original song introduced during the GreeN era, released on July 11, 2013. The track is a playful parody of the well-known Israeli folk dance song "Mayim Mayim" (マイム・マイム), a fact immediately evident from its title—"maiム" phonetically mirrors the Hebrew "Mayim" (מים, meaning "water"). The artist credit—にしもと先生 (Nishimoto Hideo), タクマ, and どんちゃん, with the parenthetical ちょっと盛りました。 ("We went a little overboard")—captures the track's self-aware, comedic spirit. The song originates from Nishimoto Hideo's manga project "読者専用検索マガジン ちょっと盛りました。" (Readers-Only Search Magazine: We Went a Little Overboard), a gag series that ran in Weekly Shōnen Magazine. Nishimoto was no stranger to music games: his earlier work "もう、しませんから" (Mō, Shimasen kara) had previously crossed over into pop'n music 13 Carnival via the track "セイント★セイジのうた." The jacket illustration reinforces the collaborative gag—the left figure is the don-chan character, the right figure is Takuma, and the center is Nishimoto himself. The MASTER chart (designed by はっぴー / Happy) is known for a distinctive "washing machine" passage where players must trace clockwise and counterclockwise SLIDE patterns, requiring coordinated two-handed movement. The Expert chart was designed by ニャイン (Nyain). Over the game's lifecycle, the chart levels—particularly Expert and Master—have been adjusted upward multiple times, with Master rising from an original level 11 designation (GreeN era) to its current 13, reflecting the chart's lasting challenge relative to newer content.
