Overview
Deicide is an original song commissioned for maimai でらっくす PRiSM, composed and arranged by void (Mournfinale) with vocals by Hazuki Koizumi (古泉葉月). The track serves as the climax piece of the Heaven Area 8 story arc, capping a narrative in which Lucifer, a fallen archangel and former "Knight" of heaven, rallies demonic forces for a renewed assault on the celestial realm. Its lyrics, sung in English, trace a personal vow of resolve and companionship through conflict, with the refrain "I will deicide" anchoring the song's central theme of god-slaying rebellion.
void (Mournfinale) returned to maimai with Deicide after a prior contribution, Revive The Rave, bringing a driving hardcore-electronic style at 163 BPM. The song's jacket art and accompanying movie by わっふゑ (Wafuwe) visually evoke the Heaven Area's angelic-demonic iconography. In gameplay terms, the Master chart (level 14.4, designed by サファ太) and Expert chart (level 12.0, designed by 鳩ホルダー) both feature dense patterning characteristic of late-PRiSM boss-tier tracks, with the Master chart carrying 99 Break notes across 874 total note events.
