Hyakki Yakoushou

Hyakki Yakoushou is a supernatural horror mystery series following Ritsu, who inherited both a sixth sense and a demon guardian named Blue Storm from his grandfather. The pair finds themselves drawn into strange occurrences and unexplained phenomena, investigating the mysteries behind each supernatural event they encounter. The series presents a collection of independent stories that build a shared world, introducing supporting characters who each grapple with their own encounters with the otherworldly.

This twelve-episode short-form series aired in spring 2026, concluding its run on the platform. The episodic structure allows each installment to stand alone while developing a larger cast and expanding sense of the world inhabited by Ritsu and Blue Storm. Viewers interested in atmospheric horror and character-driven mystery will find the blend of standalone narratives and recurring relationships appealing, as the series prioritizes exploring how different people respond to supernatural circumstances rather than following a single overarching plot.

The show's short-form format makes it accessible for viewers seeking horror content that doesn't demand multi-season commitments, while the supernatural mystery elements provide the kind of layered storytelling that rewards attention across multiple episodes.
