A enenra (煙々羅, lit. "lightweight-fabric smoke") is a yōkai, or Japanese monster, that is comprised of smoke.
Enenra resides in bonfires and, when it emerges, it takes the form of a human. It is said that an enenra can only be seen by the pure of heart.
The character 羅 in the enenra's name is meant to draw a comparison between the enenra and the lofty characteristics of lightweight cloth.
