From the Start, I Use My Gag Ability, Answer the Summons, and Become King Arthur

Kigeng thought of himself as a meme master. Ever since childhood, his mind had come with something like an encyclopedia of memes, letting him come up with the right meme in any situation. Unfortunately, no one ever believed him. Just as Kigeng was beginning to doubt his sanity, a dump truck came barreling toward him... proving that his meme powers were real. After that, Kigeng discovered he had been reincarnated on an infinite-flow platform, where he could meme to his heart's content. And the first meme was just the thing to deal with the person who had summoned him... "I have answered your summons. Are you my Master?"
