World Vanquisher is a high-energy instrumental track by void (Mournfinale), originally created for CHUNITHM STAR before crossing over into maimai as part of the ONGEKI & CHUNITHM genre. Debuting in maimai MiLK PLUS on June 21, 2018, the song arrived as a collaborative boss track bridging SEGA's three arcade rhythm game families. The maimai version uses a shorter edit (2:21) compared to its CHUNITHM and ONGEKI counterparts (2:41), and an extended album version appears on void's release Perfect Solitude as well as the CHUNITHM ALL JUSTICE COLLECTION ep.II soundtrack. True to its title, World Vanquisher delivers a relentless, driving arrangement at 170 BPM, with pounding synth leads, aggressive basslines, and a cinematic sense of scale. The jacket artwork features the CHUNITHM character Richtschütze (リヒトシュッツェ). The song has since appeared across multiple rhythm game platforms including Arcaea, GROOVE COASTER, Muse Dash, and even as BGM in SEGA's BORDER BREAK, cementing its status as a staple crossover pick. In maimai, the Master chart (level 14, constant 14.3) designed by 小鳥遊さん is known for its dense patterning and slide-heavy sequences, while the Expert chart (12.8) by Jack offers a demanding warm-up at a lower difficulty tier.
