Ike is the name of the demon family, called the "Strongest Magician in the Demon King's Army", and can capture the fort by himself.

The way he wipes out his enemies with his immense magic is just like the "monster" itself, an existence that is feared by allies and enemies alike.

However, he had a secret that he couldn't tell the other demons.

I am, in fact, a human being.

When he worked hard to use his "modern knowledge" to keep his secret from being exposed, he was treated as a "master general", and today he's still the driving force behind the Demon King's army's rapid advance.
