I write an Isekai about communist revolution until an anime is made out of it

When one dumbass is run over by truck-kun while posting a daily isekai communism meme, he is himself isekai'd. A palace, a princess, and a quest, but all is not well beneath the golden spires and great trees. The knowledge of earth is a boon far greater than anything on this world's terms, but is a random loser truly up to the task of wielding it?
