SUPER AMBULANCE is a high-speed instrumental track by AJURIKA, the alias of veteran composer and sound designer Akitaka Toyama (遠山明孝). Originally introduced in Sega's ONGEKI bright arcade rhythm game, the song was ported to maimai DX FESTiVAL on October 21, 2022, as part of a limited-time collaborative area linking the Touhou Project, ONGEKI, and maimai. Clocking in at a relentless 200 BPM and carrying the in-house genre label "SUPER CORE" from its home game, the track blends driving synthesizer leads, punchy percussion, and a brisk, anthem-like chord progression that evokes a cinematic, high-stakes atmosphere. Toyama, who spent years at Bandai Namco contributing to the Tekken, Katamari Damacy, and Ridge Racer series, brings that same compositional dynamism to this compact two-and-a-half-minute piece. In maimai, the song is best known for its level 14 MASTER chart (difficulty constant 14.3), a joint creation by two respected note designers, 翠楼屋 (Suirouya) and あまくちジンジャー (Amakuchi Ginger). With 1,030 total notes spread across all five note types (Tap, Hold, Slide, Touch, and Break), the chart acts as a dense, high-speed endurance test that mirrors the track's unrelenting energy. The Expert chart, designed by Jack, provides a substantial warm-up at level 12.0. Initially locked behind the 東方Project×オンゲキちほー (Touhou Project × ONGEKI Area) event, requiring 550 km of in-game travel distance during FESTiVAL, SUPER AMBULANCE became permanently available by default from the FESTiVAL PLUS update onward. Its reach extends beyond Sega's rhythm game ecosystem; the track also appears in lowiro's Arcaea, making it a genuine cross-title instrumental shared across competing rhythm game platforms.
