Satou, The God-Killer

Demon Lords are High-rank God-Tier Demons that are nigh-invulnerable to most forms of Magic attacks. The only way to kill them is by using a Holy Sword which can only be carried and used by someone using the "Hero" Title. Satou has a Holy Sword but is not a "Hero", but he does have a Divine Sword: a lesser-ranked blade, and he has the "God-Killer" Title.
