Overview
ネガティブ進化論 (Negative Evolution Theory) is a Vocaloid track by prolific producer DECO*27, featuring Hatsune Miku. The song pairs a driving, pop-rock instrumental with a title and lyrical theme built around self-deprecation and perceived personal failure, a "negative evolution" that subverts the conventional growth narrative. It was added to maimai DX during the Splash PLUS update on March 18, 2021, categorized under niconico & Vocaloid.
In the maimai arcade series, the track is notable for the trajectory of its Master chart, which originally debuted at level 12 before being upgraded to level 12+ (difficulty constant 12.7) in the UNiVERSE+ revision, a recognition of its demanding pattern density. The DX chart set makes substantial use of Touch notes across all four difficulty tiers, with the Expert and Master charts designed by 隅田川星人 (Sumidagawa Seijin) and Jack respectively. The song is accessible in every operational region, Japan, International, USA, and China, as a standard Splash PLUS era release.
