Raoul, who had defeated the demon king as the strongest hero, should have become the savior of the world.

Having his treasured companions and family killed by power-hungry aristocrats, he was executed with false charges brought against him by the princess. Just before his life collapsed, at last, his heart fell into darkness.

...I'll tear those traitors from limb to limb. Burn them at the stake. Sever them to pieces. Skewer them. I'll kill every one of those bastards without mercy and make them taste hell's suffering.....!!!

Obtaining the power of darkness, Raoul was revived. Sneering, he vowed revenge.

“Oh, I’m looking forward to it – from now on, I'll bask in their blood as I please.”
