They Say the Saint Has Black Hair and Black Eyes, and I, the Demon King, Have the Same. Is That All Right?

A kind-hearted, big-cocked, handsome human king x a beautiful black-haired, black-eyed demon king who was mistakenly summoned as a saint.

The country that attempted to summon the Saint from another world was missing various knowledge, and mistakenly summoned “the nearest person with black hair and black eyes.” Even the knowledge that the Demon King also possessed the same traits had been forgotten. The Demon King, who becomes endearing to the people in the peaceful country, decides to elicit some caution and says, as a price to deal with the demonic beings, “The one with the largest pen*s among you must embrace me.”
