Traits

Koami "Waterfall" tails at their base are usually rather short to medium-length in bone structure. 
These tails get their namesake because they are wavy or curly in feathering, and usually sport extremely long, silky hair.

These "waterfalls" often reach past the knees, and sometimes even drag along the ground behind an Arkaine.
