Tsurube-Bi
Tsurube-Bi (drooping flame) are a type of youkai from the GeGeGe no Kitarō franchise. They're best known for showing up in the 1968 anime adaptation, where they're actually portrayed as a single character rather than a species—though manga chapters occasionally do the same thing. The name's pretty straightforward if you know Japanese: it literally just means a flame that hangs down, which tracks with how they look.
