Fein is an arrogant mamodo that brags about himself becoming the next king. Little is known about him, but his elements are wind and speed and he is very sadistic.
Gash defeats Fein when he uses his third spell Jikerdor for the first time, which magnetizes Fein to a nearby billboard (a water tower in the anime), holding him in place while Gash burns his book. In the end of the battle, Fein is seen in a picture with all the mamodo pictured by Gash given to Kiyomaro.
