A regular student- Miko- trying to survive high school finds himself summoned into a strange, fantastical world on the verge of war. He soon finds out that he is the only person who can fulfill a prophecy to defeat the demon king. His job is simple: use the system to level up until he is strong enough to wield the ancient demon sword, and save this new world. And there's a bit more upside, a cute (if ferocious) princess! Can Miko become strong enough to defeat the demon king, or will this new world he found perish?
