A monster girl whose upper body is human and whose lower body is snake-like. Lamia and naga are often rendered so similarly as to make it merely a matter of style which one a serpent-legged character will be called.
Naga are from Hinduism and Buddhism, and literally means "cobra", while Lamia is Greek. They can appear with varying degrees of humanity, but typically have fully human torsos.
The Japanese, apparently not having either of these myths a major part of their tradition, tend to ascribe lamia/naga with personalities like those they associate with snakes in general and lamia are often the tsundere types.
