I Work in a Library as an Evil God

Lucifer, the supreme ruler of the demon realm, can't stand dealing with official business around the clock, so he disguises himself as a powerless good-for-nothing and takes a job as a librarian at the worst magic academy in the human world.

All he wants is to drink tea and read human novels. One commoner girl at the academy often brings him sweets, making his leisurely days even more pleasant.

Then the academy is invaded by a formidable enemy. The headmaster and the elite students are all defeated, and the girl is gravely wounded. The enemy leader loudly declares that they will slaughter everyone at the academy.

Just as all hope seems lost, Lucifer clicks his tongue in resignation, sets down his teacup, and picks up a trampled wand from the ground. He steps forward, his terrifying magic so powerful that space itself begins to shatter. He looks at the enemy as if they were a bunch of noisy insects. "Do you have any idea how serious the consequences are when you give a retired senior official a bad case of morning grumpiness?"
