"The Demon King and the Holy Angel were once opposing forces.
But because of one tiny change I made... All right, actually, I changed quite a lot. I was drunk at the time, so I don't even know what all I changed.
For example, the Demon King being chased around by the Holy Angel, who calls me darling; An, once the foremost of the Four Great Bosses in the later stages, becoming my servant; and what else is next? A vampire princess who cries and begs to be my concubine, and all the secrets of this world that exist in my mind.
In this world, I've become invincible, okay?
But...
"Um, darling, it seems we're out of money again."
