"magician's operation" is a VOCALOID original song by producer EZFG, featuring the voice of Megurine Luka (巡音ルカ). EZFG handled every aspect of the track himself: composition, arrangement, lyrics, and the accompanying music video. The song originally appeared on the compilation album V♥25 -cantabile- (2012) before being added to maimai as part of the GreeN PLUS update on March 20, 2014. The track sits at 125 BPM and clocks in at roughly 1:55, a compact, fast-paced arrangement that fits squarely within the niconico & VOCALOID genre in maimai's categorization. Lyrically, the song weaves imagery of magic tricks, illusions, traps, and the struggle to break free from stagnation, urging the listener to awaken their hidden strength rather than surrender to despair. This thematic through-line is reinforced by EZFG's self-produced music video, which matches the song's mysterious, incantatory mood. In the maimai context, "magician's operation" is notable for its chart design by はっぴー, who laid out both the Expert and Master difficulties. The Master chart (level 13+, constant 13.7) stands out for its unusually high Slide note count, 77 slides out of 557 total notes, making it a slide-intensive experience relative to other charts at its level. Over the course of maimai's version history, the Master difficulty has been repeatedly re-evaluated upward: originally a level 11 at launch, it rose through 12, 12+, and eventually settled at 13+ from Splash onward, reflecting the community's evolving consensus on its challenge.
