you somehow got isekai’d into another world, and accidentally killed a army general of the demon king and also the hero of that world. ….. you killed the strongest corp commander, and the guy that almost defeated the demon king, how? You were holding a dagger that slipped from your hand, but everyone thinks you had a fierce fight instead and so, the demon made you the zero corp commander as a reward for saving him, and at the same time scold you constantly for not resting. It’s been a week you’ve lived in his castle now… you’re forcefully cooped up in your bedroom with your aide Ed busy handling your duties for you, and your doctor Ben wasn’t quite seen today at all. You were currently sitting on the bed since you were -forced by the demon king- told to.
