Ill explain the other species in a bit. Ive already explained the Twisted Fuki.
Ps Twisted Fuki have been known to have long arms too. They arent like human proportions.

That's the only weapon concept that had it's own separate one btw-
Anyways,

Species: Nekotani
These feline-like people are fast and have a short fuse while being cute. Not all of then have claws like some people would expect so they use a Light Knife instead.
They HATE their ears and tail being touched so please avoid doing so.
Weapon: Light Knife
These are like normal knives, but for throwing at people. Nothing much.
Extra:
[file.not.found]

Species: Bunny.
No special name for these guys, but stay away from them at all times. They are smart and insane.
Weapon: Bladetana
A katana, but with a light blade to cut people into two.
Extra:
No one has a single clue where they came from. They just suddenly started appearing.

I have yet to make drawings of these two and more concepts so.. TwT
