(Fandom Crossover) It's Hard Being a God

Detailed version: As the "mother" of many nonhuman intelligent species, They are deeply respected and hold a lofty status. At the same time, however, all humans hate Them. In their eyes, They are no better than a thief or a bandit. Legend has it that They once stole the power of the Supreme God of Light, recklessly disregarding whether the world would survive, all for the sake of becoming a god. The world nearly collapsed when the balance of power was thrown off. Though They achieved Their wish and became a god, the people came to resent Them. They called Them the Demon God, the Evil God, and saw Them as the embodiment of calamity. The races They created were collectively known as demons., (Excerpt from Mythology Before the New Era) Actually, if circumstances allowed, They would really like to cry out like Dou E: "I'm innocent!!" One-line summary: Basically, this is the story of an innocent, sweet girl who gets bullied, framed, and trained by the author in every way until she becomes a chuuni, sadistic, scheming emperor-type villain, then teams up with a second-generation Demon King from another world to take revenge on society(?). Author: Isn't this really just cleaning up a huge mess? = = P.S. The pairing is Fu X Jie. The heroine is just off to the side, drinking tea and watching the show while destroying... um, no... maintaining world peace (serious face).
