Kakushouron

Starting from the bottom means the only way left is up — that one line basically captures the whole energy of this music video. Kakushouron is a single-episode music piece by Ryushen, created as the opening theme for Necronomico no Cosmic Horror Show, and it hits harder than you'd expect for something under four minutes. The lyrics lean into themes of resilience and refusing to give up, with this undercurrent of defiance that pairs surprisingly well with cosmic horror imagery. There's something about watching visuals that hint at Lovecraftian dread while the song tells you nobody plays the game of life just to lose. That contrast between existential terror and raw determination gives the whole thing a unique flavor. It works both as a standalone piece and as a gateway into the anime it introduces — you come for the song and leave genuinely curious about what kind of show needs an opening this intense. If you're into how the Kagerou Project used music videos to build out a larger narrative world, or if you appreciate anime openings that feel like their own self-contained stories, this one's worth your time. It's short, it's atmospheric, and Ryushen's vocal performance carries real weight. Not every music video earns a separate entry, but Kakushouron makes a case for itself.
