Frej

Frej is a "child", or soul, that you can summon to fight your way through the world of Destiny Child.

Profile
One of the most famous and promising Archfiend candidates in the entire Infernal Realm, Frej takes his name from the nobleman of the gods. He is supremely arrogant, as one would expect of pretty much any demon who isn't the young master, and he couldn't care less if his attitude loses him friends or makes him enemies. After being weakened in a fierce battle against a childhood friend soon after arriving on Earth, he began behaving recklessly in order to recover his strength, which led to Lisa eventually abandoning him.

Children
It should be noted that in this case, the use of "child" does not mean the character is a child. Like all the other summons in this game, "child" simply refers to the soul that is being summoned.
