Ankoku Demon created from fear

Ankoku is A demon with a canine body.He roams the Plains in search of a lost soul (the puppets in the picture)
those 'lost souls' are ment to resemble the fear of a person. He will snatch up a decent size fear and eats it, giving the living person a wave of content for a while, but as soon as the Ankoku gets hungry again it will climb in the tree it snatched the lost soul from and slowly but surely will make its way in the dreams and eventually reality world of that person and kill it.
The bigger the Ankoku's tail is the stronger and older it is.
