Supreme Monarch: Iron Wrought Throne

In a weird twist of fate, a man woke up tied up to a pole and about to be burned alive like a witch. As if that wasn't weird enough, he wakes up in the body of the last member of the royal family of the human kingdom, Leon Maxwell.
At first, he decided to joke around about the situation since it was too ridiculous to be true. Still, things took a dangerous turn when he began to feel the heat of the torches that were about to start the fine that would turn him into barbecue for his executioners, who looked like beastmen.
Somehow, he was rescued by the last allies of his family, who sacrificed themselves to buy him time to escape. Knowing that he doesn't have any other choice but to assume the identity of Leon Maxwell and fight for his life, the man goes on an insane journey where all of the world wants him dead.
In the end, Leon Maxwell will come to learn that in this insane world of beastmen, dragons, elves, dwarves, fairies, orcs, goblins, vampires, merfolk, and humans, he will have few allies, and he doesn't have any other choice but to reforge his by right throne. Perhaps it won't be that hard since he has the blessing of the deity that created humans in that world. The only problem is that all the other species have a deity, too, and they definitely don't like him...
