(A prophecy--
The seal that has held back the Demon Realm for six thousand years will be broken once more,
and the world will plunge into eternal darkness.
The fate of humanity will come to an end...)
In a world of swords and magic, who is friend and who is foe?
Is there really blood beneath the human skin? Is the heart behind the demon mask black, or white?
The war between gods and demons, the Demon Cult, the Seven Sins, the Hero Summoning Spell, the Demon King's secret...
"Looks like I'll have to get a little serious."
"Demons, let the world feel your fury!"
"Welcome back, my king."
