Kubikajiri

Sources present the Kubikajiri as a restless, corporeal ghost whose defining compulsion is to find and consume heads. Many accounts frame the creature as headless and therefore searching graveyards at night "in order to look for its own head." While some modern or fan accounts speculate about social origins (for example, that certain kubikajiri are the restless souls of the starving dead), the core attested motif in the sources is a headless spirit driven to seek heads rather than a clearly documented, consistent origin narrative.

Across reliable references the primary visual characteristic of the Kubikajiri is that it is headless. Secondary or modern embellishments appear in some popular sources (for example, a fandom entry describing it as an old man in white burial shrouds), but these are not corroborated across the concise references. Several sources also note a sensory marker—most notably the smell of fresh blood—that accompanies its presence. Descriptions otherwise focus on its headless state rather than a fixed, detailed garb or morphology.

The Kubikajiri's defining behaviour is to seek and consume heads: sources state it "eats the heads of its victims, be they living or dead, animal or human." It is reported to haunt graveyards at night as it searches through graves, commonly described as looking for its own missing head. The creature's activity centers on graveyards and nocturnal predation; sources attribute an olfactory sign (the scent of fresh blood) to its presence. More graphic claims (such as leaving a pool of gore) appear in single fandom-style accounts and are not uniformly attested in the concise references.
