(A clever urban fantasy with a bit of a brain. No harem, no System, no invincibility. A low-key fanfic with some satisfying moments.)
After being tormented by an evil spirit for half a year, I willingly signed a contract of servitude.
I became the only human in two hundred years to sign a contract with a demon.
He asked me to teach him Ancient Elvish, so I turned the affirmations in Satan's scriptures into questions.
The scriptures judged him unfaithful and devoured the evil spirit until not even bone fragments remained.
I succeeded him as director and wanted to buy back my contract with the demon.
The owner of the Moonlight Tavern in the dungeon asked for four trillion gold coins a year!
Only later did I learn that the previous six directors had either died or gone mad. I was the seventh.
But I didn't care. The demon who could kill me was gone.
I was the only immortal human...
I had all the time in the world to turn Bureau 407 into an economic, political, and cultural hub spanning multiple planes.
That debt wasn't much...
I paid my debts with gold, governed gods with rules, and recruited characters from other worlds with comprehensive benefits.
I became a legendary civil servant whom anime characters lined up to meet.
And a plane-hopping seller whose goods the gods begged to have shipped!
