Overview
Marshall Maximizer (マーシャル・マキシマイザー) is a high-energy electronic-rock Vocaloid track by Hiiragi Magnetite (柊マグネタイト), a producer recognized in the Vocaloid and doujin music scenes for aggressive, distortion-heavy compositions at elevated tempos. The song features KAFU (可不), a CeVIO AI voice bank from the "musical isotope" (音楽的同位体) series developed jointly by KAMITSUBAKI STUDIO and Gynoid, whose vocal delivery cuts through the dense instrumental arrangement. Guitarist C'Na provides the track's distorted riff backbone, and the accompanying animated music video was created by illustrator and animator あさ.
The lyrics weave together scientific and existential imagery, "critical experiments," "Avīci hell" (無間地獄), and the recurring cry of "Fail!", that mirror the relentless momentum of the 190 BPM instrumentation. The in-game collection title "失敗！（Fail）" is earned by clearing the song with exactly one MISS, a direct callback to the exclamation that punctuates the chorus. In maimai, the MASTER chart (level 13, constant 13.2) was designed by じゃこレモン and is characterized by concentrated Slide-note patterns during the chorus sections. The EXPERT chart (level 9+) was designed by はっぴー. Originally added to maimai DX FESTiVAL on November 4, 2022, the song also crossed over into SEGA's CHUNITHM series, debuting in CHUNITHM SUN on February 9, 2023.
