Without warning he departs overseas, but not before bringing Basara two beautiful step-sisters. What Basara doesn't know is that Mio and Maria's true forms are actually the newbie Demon Lord and a succubus! Almost trapped into a life of servitude, Basara forms a reverse contract by accident and ends up becoming Mio's master. Hijinks ensue as Basara finds himself in one ecchi situation after another. However, Mio's life is in danger as she is pursued by both demons and heroes alike!
