Japan’s Visual Kei masters of brutality, Deviloof, have returned with their latest sonic assault, ‘因習’ (Inshuu). Known for pushing the limits of extreme metal within the Visual Kei world, Deviloof has once again delivered a track that is as savage as it is mesmerizing. Blending deathcore ferocity with theatrical aesthetics, ‘因習’ is a high-intensity barrage of guttural screams, punishing breakdowns, and intricate guitar work that reaffirms Deviloof’s place at the forefront of the heavy music scene.
Right from the opening seconds, ‘因習’ grabs listeners by the throat with blast beats, bone-crushing riffs, and an eerie atmospheric intro that builds tension before unleashing absolute mayhem. The song’s structure is relentless, moving between brutal deathcore sections, dissonant melodies, and chaotic transitions that keep the energy at a maximum.
Lyrically, ‘因習’ delves into themes of deep-rooted societal constraints, suffering, and rebellion. The song’s title translates to “custom” or “tradition,” suggesting a powerful message about breaking free from oppressive norms. The vocal delivery is nothing short of monstrous, with the band’s frontman alternating between low gutturals, high-pitched shrieks, and demonic growls, amplifying the track’s intensity.
The production on ‘因習’ is absolutely crushing, perfectly balancing precision and chaos. The guitar work is intricate yet ruthless, weaving in moments of melody that contrast with the sheer heaviness of the breakdowns. The drums are machine-gun fast, never letting up as they drive the track forward with punishing aggression.
With ‘因習,’ Deviloof continues to defy expectations and push the boundaries of Visual Kei into the realm of extreme metal. Their signature blend of theatrical horror, brutality, and technical musicianship makes them one of the most unique acts in Japan’s heavy music scene. For fans of deathcore, blackened metal, and extreme Visual Kei, this track is an absolute must-listen.
