The Hero Transfered Me In Another World

"Behold, for I am your new Emperor" "Hm? The hero Brought me a gift and why are you attacking me?" I, S'lva the newly appointed Demon Emperor for some reason, woke up in a different world. A world where the concept of Magic is a common thing and weapons are greatly disgraced. I discovered magic could be the answer to the mysteries of my existence. In a place where demons such as myself are an unknown existence, I aim to become the first Demon Mage to ever live.
