Everyone Says I'm Not an Edgelord Anymore [Book Transmigration]

-Novel blurb- A great demon king who had slept for a thousand years transmigrated into a novel and encountered Jiang Jin, the villainous boss before he had turned evil. The Demon King had lost his magic and needed to make a deal with a human. So he lifted his proud little chin. “You summoned me? Since you woke me, I’ll grant you three small wishes, provided you immediately prostrate yourself and loudly swear allegiance to me for all eternity.” The young Jiang Jin gave him a look, then turned and walked toward the police station. - Ever since he met Lu Er, the chuuni who claimed to be a great demon king, Jiang Jin found that there was suddenly no one left to hate in his miserable, unlucky life. Everyone he’d once wanted revenge on had somehow met with disaster. The dark life he’d thought he could never escape suddenly seemed bright. Everyone else thought the bad guys were getting what they deserved and Jiang Jin was finally having a stroke of luck. Only the great demon king, Lu Er, proudly told Jiang Jin, “You really should kneel and thank me for my benevolence.” Jiang Jin: “...Was that you?” Lu Er beamed. “I’m amazing, aren’t I? I want a little cake.” Jiang Jin smoothed down the cowlick sticking up because Lu Er had slept in an awkward position. He didn’t believe him at all, but still gave him a compliment. “Yeah, amazing. Do you want strawberry?” - Jiang Jin thought that if they could keep living like this, then so what if Lu Er never got over his chuuni phase? He didn’t care. Until one day, dark clouds blotted out the sun and thunder boomed. Monsters unlike anything seen before invaded, throwing the world into chaos and giving ordinary people a terrifying taste of the supernatural. As one of the few people who had awakened an ability, Jiang Jin now had the responsibility of saving the world. Sadly, this mission was too difficult. Everyone prepared for failure. The wounded ability users stared at the sky, waiting for the final destruction But what arrived before the apocalypse was a little pink parasol. The handsome man who called himself a king leaped from a thirty-eight-story building and effortlessly sliced off every monster’s head. He used the little parasol he usually carried for shade to shield himself from the bloodied remains raining down around him. Sunlight shone down once more. Everyone gaped, then their knees gave way and they collapsed to the ground. Only then did Jiang Jin finally understand. Lu Er really was a king, an all-powerful king. He alone had been foolish enough to think of him as a cute but silly chuuni. Fortunately, his king was magnanimous and still willing to protect him one last time. - [A little scene: Applying for a temporary ID] Staff member: Name and age?
