Destined Marionette is an original instrumental track by doujin musician ビートまりお (beatMARIO), best known for his energetic, high-BPM electronic compositions and prominent presence in the Bemuse (BMS) and SEGA rhythm game scenes. The song holds special significance as beatMARIO's very first original composition, a self-described "theme song with his hobbies on full display." It was originally created for the B-1 CLimaX "The Revenge" BMS song contest, where it claimed the top spot under the TECHNO genre label. The track is a high-energy electronic piece at 186 BPM, driven by punchy synth leads, rapid-fire arpeggios, and the signature production style that would come to define beatMARIO's later work. The jacket artwork and music video were handled by inukoro, adding a distinct visual identity to the song's marionette motif. In maimai, Destined Marionette appears as a GAME & VARIETY (ゲーム＆バラエティ) category song introduced in the PRiSM PLUS update on May 21, 2025. Its Master chart, designed by ぴちネコ (Pichineko), features a dense 1023-note layout at level 14 (constant 14.3), while the Expert chart by サファ太 (Safata) offers a level 12 challenge (constant 12.5). The song was also simultaneously added to CHUNITHM VERSE and later made its way to SOUND VOLTEX EXCEED GEAR, making it one of the few tracks to span multiple SEGA rhythm game platforms in a single release cycle.
