Summoned Hero

This is your typical summoned hero type of novel But not your usual hero summoned at the human king side. This time, the demon king decided to summon a hero. If mere human can do it, why the demon king can't? What kind of hero will be summoned for the demon king? ------------- WARNING ------------- This series contains ero-scene and the main theme is comedy... 18++ PG rated (parent guidance advised but seriously don't let your parents know you read this lol) Ps:those who dropped the series because of short early chapter, it has been made longer.. For those who dropped the series because you can't handle the ecchi-ness, I feel sorry for you..
