Opening a fantasy anime world with the style of Mount & Blade

Thanks for the invitation. I am in another world, a nobleman, who has just awakened his past life memories and the Mount & Blade system. His territory is being attacked by a group of greenskins.
But... wait!
Why do those goblins look so much like the art style in "Goblin Slayer"? And why are they ruled by orcs who keep saying "I think"?
The scumbag princess of the stunt warrior, the elf queen of the black beast, the sword saintess of Goblin Slayer...
In the end, Liu Tianyu concluded: "There's something really wrong with this world!"
