Mafdet

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

Profile
A Child born when a timid young girl formed a contract with a demon to find her father's killer. In accordance with that desire, she took the name Mafdet, after the goddess of justice. Possessed of the same heroic spirit as her late father, she is willful, stubborn, and obsessed with justice. She sets an example by acting as a disciplinarian for the other Childs.

She treats her pactmaker as her own daughter, biding her time until the day she can avenge her father.

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.
