 Aperance 

Ranicorns are creatures with colorful bodies. It is unknown if male ranicorns are shorter than female ranicorns or if lenth veries due to the fact that out of the only three that have been seen only one was male. The language of ranicorns seems to be Korean, so that is where they might have origenated.
