Alright...Crusader Backstories somewhat revealed. Greater detail when their fights come. So in a shell-nut:

Maria: Orphaned, lived alone being called a Witch, driven away due to her wierd powers.

Kain: Half-Demon, Demon Hunter. Except unlike a cool variant of this, it's half-succubus.

Ivan: Long family history of being Crusaders for Ilias' churches.

Issac: He's a boy, who became a cosmic mage, who served Ilias as a weapon and calls Miceala Mom.
