The horror lives in the sound design, not the jump scares. Yuuri Kuriyama's composition warps space around Miku's vocals until you can't tell if you're listening to a love song or a descent. One minute captures what a full season of anime builds toward, and it's designed to loop in your head for days.

Hyu~dorodoro is a one-episode music video set to the Yuuri Kuriyama song of the same name, with Hatsune Miku and MEIKO providing the vocals. The animation is by sakiyama. The song and its video belong to Project VOLTAGE, a joint project pairing Pokémon with Hatsune Miku. Its genre tags place it in horror and the supernatural.
