Enenra

Enenra appears in classical yōkai compendia such as the Konjaku Hyakki Shūi (circa 1781) and is recorded in modern reference sources as a smoke- and darkness-composed yōkai. Sources describe two origins or types: the common type are beings born as enenra (native smoke-spirits), while a rarer type are humans who died and were transformed into enenra. Beyond these classifications, the supplied sources do not provide a broader cosmogonic narrative or a detailed origin myth.

Sources consistently describe the enenra as composed of smoke and darkness rather than solid flesh. When it leaves its habitual dwelling in bonfires it is said to take a human shape or form; the supplied material does not elaborate further on size, clothing, color beyond 'darkness,' or other distinguishing physical features.

Recorded attributes in the supplied sources are: residence in bonfires, emergence from flames, and the capacity to assume human form on emergence. The sources also state that an enenra can only be seen by the pure of heart. Beyond these points the provided materials do not list additional powers, capabilities, or behaviors.
