Simple: It's heroes of might and magic in anime. If you liked the game, you'll like this anime. It purely awesome. They follow every step of the creation of a evil empire. I really hope there will be more seasons. Characters have charisma, they are strange in various way, but still evil, and that's nice to see. Scenario is great and well worked. It's not an isekai like we are used to, here, the isekai is just a excuse to introduce the character, but hey who cares, the story is original and great ! I don't understand the curent rating, I think it deserve more ^^
