MIRROR of MAGIC is the designated theme song for maimai ORANGE, the third main version of the arcade rhythm game, released on September 18, 2014. The track pairs composer and arranger Shoichiro Hirata with vocalist-lyricist SUIMI, marking their second joint contribution to the maimai series after "Cosmic Train" from the GreeN era. Musically, the song is a mid-tempo 2-step pop piece at 135 BPM, opening with a scat vocal passage before settling into a sweet, bouncy groove. Hirata noted that the creative brief specified a "2step" genre, and he aimed for a sound that would feel timeless, playfully remarking that he wanted it to sound like it could accompany a cosmetics commercial. The final bars introduce a four-on-the-floor kick pattern as a subtle structural twist, giving the arrangement a gentle lift as it closes. Lyrically, the song follows a young woman racing against the clock to get ready for a date, frustrated with her skin and struggling to perfect her makeup. She addresses her mirror as both confidante and instrument of transformation, weaving cosmetic terminology, eyeliner, lip liner, cheek blush, foundation, through the verses. The chorus reframes makeup as "the only MAGIC that changes me," tying appearance to confidence and happiness. Within the game, MIRROR of MAGIC received standard charts across all four difficulties. The Expert chart was designed by mai-Star and the Master chart by Jack. Over successive version updates, the chart levels were revised upward, the Master chart, for example, began at level 11 in ORANGE and climbed through multiple increments to its current level 13 by the time of UNiVERSE PLUS. In 2026, an UTAGE (banquet) chart was added under the title "鏡" (Mirror), designed by the alias "MIRROR of ADVANCED(↻)."
