Nekomata

The Nekomata is a type of Yokai. They are created when a cat is exposed to emotional or apparitional energy. Upon reaching a certain threshold, their tales will split into two and they will gain new powers. These powers include levitation, the ability to speak and understand human language, and the ability to devour souls.

Nekomata no longer can sustain themselves off of normal matter, instead they must feed souls. While usually passive, or even helpful at times, they must be hostile in order to feed. Most Nekomata do their best to feed on the souls of hostile creatures, as to not hurt their owners or allies. However, sometimes a Nekomata will become Soulstarved, and forced to feed on the souls of any creature nearby.
