World Library.
As its name suggested, it was the largest and oldest library in the world.
All the books about anything in the world were in here, and the only problem was whether people could find them or not.
From the 1st floor to the 79th floor were just ordinary books, not worth mentioning.
However, on the 80th floor, which was also the highest floor, those books were the keys to the ultimate knowledge.
The knowledge of the gods, the cursed things.
And, those books also had another name:
Things that should not exist in this world.
On the 80th floor, the librarian was sitting leisurely, enjoying this evening.
However, the peaceful atmosphere he had created was ruined when one of his employees appeared.
"Sir, something really bad happened!"
Frowning, he shouted:
"Shut up! This is a library!"
"…!"
Realizing his irresponsibility, the employee immediately covered his mouth.
"So, what happened?"
The librarian asked again, rubbing his temples with both hands.
