Nanka Youkai!?

When Hide, who goes by the nickname Hi-De, crosses paths with a mysterious girl named Miru, his ordinary life takes an unexpected turn. He soon discovers that Miru possesses a highly unusual and involuntary supernatural ability: whenever she senses the presence of a spirit or detects that a strange occurrence is being driven by paranormal forces, she cannot help but sneeze. This peculiar physical reaction serves as an infallible radar for the unseen world, instantly alerting them to otherworldly disturbances hiding just beneath the surface of everyday life. Bound together by this strange discovery, the two begin traveling side by side, stepping into a hidden realm where the impossible becomes routine. Their journey exposes them to a vast and unpredictable spectrum of paranormal activity, bringing them face to face with restless ghosts, fearsome demons, lingering human spirits, and even divine beings. Each new encounter tests their courage and deepens their bond, as they navigate a world teeming with entities both benevolent and malevolent. With Miru’s sneezes guiding their path and Hi-De standing by her side, the pair must confront the mysteries of the spiritual realm, unraveling the causes behind every bizarre phenomenon they meet along the way.
