Kokkai clan

The Kokkai clan was a clan made completely of draconian's "humanoid dragons". They inhabited an island that was dangerous to anyone who wasn't a Kokkai or there allies. Draconian's have diamond hard scales horns protruding from the head wings coming from the back as well as a tail their talons can cut through steel and with pure strength alone could lift the weight of a bijuu. This when they are actively using there power, when they aren't they look like normal humans except with pointy teeth and black sclera.
