Vicious tricksters and thieves from Japanese folklore, Ko-tengu resemble large birds of prey with human features. They usually dress in robes like a wise hermit and they carry weapons, which they stolen from human homes or temples. Ko-tengu behave more like birds then people. They live solitary lives but they have been known to work together or with other mythical creatures to achieve goals.
Ko-tengu are hoarders. They loves to steal and collect trinkets and magical items, which they will sometimes trade. They are not peaceful creatures though. They have very little respect for people and they will eat human flesh, and commit rape and torture just for their own amusement. They will abduct people and drop them from great heights, or tie children to the tops of trees so no one can save them. Ko-tengu particularly love torturing the clergy. They revel in tormenting monks and nuns by robbing temples and trying to seduce them. They have also been known to kidnap people and force them to eat feces until they go mad.
Ko-tengu like to believe that they are very clever but they can be easily tricked by a person who is smart enough.
