Supersonic Generation is an original instrumental track by the electronic music unit Massive New Krew, best known within Sega's rhythm game ecosystem for its high-energy synth sound and driving 155 BPM beat. The song first appeared in CHUNITHM AIR PLUS in July 2017 as part of the AIR ep.VII MAP, and later crossed over into オンゲキ R.E.D. PLUS during the GEKINITHM PLUS event in 2021 before arriving in maimai DX PRiSM PLUS in March 2025. True to its title, the track evokes a sense of blistering speed, relentless kick drums, soaring synth leads, and a stadium-ready drop characterize Massive New Krew's production style throughout. An extended version appears on the duo's album OVERHEAT, offering a longer take on the same adrenaline-fueled composition. In maimai, the song is classified under the ONGEKI & CHUNITHM crossover category and features DX charts across all four standard difficulties, with the Master chart (level 13+, constant 13.9) designed by Luxizhel and the Expert chart (level 11+, constant 11.7) by 鳩ホルダー (Hato holder). Originally tied to a CHUNITHM VERSE collaboration unlock, the song became generally available in maimai from June 6, 2025.
