"Kukuku... He is the weakest of the Four Heavenly Kings."...But he isn't, he's actually the strongest!? The archenemy of the Human World, the Demon Continent.

Ralph is the weakest of the three. But, the other three, Freya, Lilia, and Lushika actually have a secret. "We don't want to fight at all!!" They completely delegated all the fighting to Ralph! They have zero combat experience! They're scaredy-cats and girls who only act tough when outside! These insanely lazy girls absolutely refuse to fight. Meanwhile, Ralph has been so stressed being pushed around and having to fight constant battles. He tries hard to escape from this black company-like atmosphere, but...

"Enough already, just fight!"
"I don't want to, though?"
"You're too much!!"
"...(Faints)"
