Nekomata

Heh, yeah. Nekomata are Cats that have lived a long time, long enough to become Youkai and have their tails split into two, and then into three, and then into four, etc. The amount of tails they have designates how strong they have, much like a Kistune, although there's only one Nekomata that's been proven to have lived for over 600 years, and it has six tails. It probably won't be dying any time soon either. Nekomata are like weaker versions of the Kasha, but they lack the 'Nekoromancer'-type abilities of the latter. (Get it? 'Neko' as in Cat? Like Necromancer, but Cats? Hah!) And yes, Nekomata can have Human forms as well, except they cannot shift between them freely, therefore they are stuck as either a cat or a Human with cat tails.
