Anime Crossover: Ruling the Heavens from Black Bullet

Fang Yuan accidentally transmigrates to a shattered world and immediately binds himself to it. He thinks he can enjoy a life where he reigns supreme over heaven and earth, only to learn that the world is about to be destroyed. As someone bound to the world, he will be judged along with it.

And so, the worlds of the heavens welcome an ultimate demon king.

Black Bullet: He puts the entire world in order, wiping out every scumbag more disgusting than maggots.

Akame ga Kill!: He unifies the Empire, puts Night Raid to work for him, and counts Esdeath and General Budo among his top commanders.

Demon Slayer: To him, demons are just cheap labor with unlimited stamina.

He is the ruler of the world, beyond the multiverse and the one supreme overlord of the mixed-anime worlds.

Many years later, when someone asks him why he was so ambitious, Fang Yuan replies:

"I didn't think too much about it. At the time, I mainly just wanted to stay alive. By the time I came to my senses, a bunch of people were calling me the Supreme Will."
