Maou Gun Saikyou no Majutsushi wa Ningen datta

I'm called "Maou Army's strongest magician."Ike, a demon who can take over a fort on his own.Cleaning up adversaries with massive enchantment, he is beyond a shadow of a doubt a beast awed by companion and enemy.However, he keeps a secret from other demons.I, in fact, am a human, as you know.He became regarded as a great commander and the driving force of the Maou's army because he kept his secret using modern knowledge.
