Known as "The Strongest Sorcerer of the Demon Lord's Army," Ike is a demon capable of conquering a fortress single-handedly.

He mows down enemies with such immense magic that he is truly nothing short of a "monster," an awe-inspiring presence feared by both allies and foes.

However, he harbored a secret he couldn't tell any other demon.

"—Actually, I'm human."

Striving to keep his secret from being exposed, he leveraged "modern knowledge." As a result, he inadvertently came to be regarded as a "brilliant commander," and even today, he remains the driving force behind the Demon Lord's Army's rapid advance.
