Shinmai Maou no Keiyakusha
“Hey, you said you wanted a sister, right?” First year highschool student, Toujo Basara, was suddenly asked by his father and fell into a state of panic. On top of that, the eccentric father told him he will be getting remarried. He then departed overseas after bringing Basara two beautiful step-sisters. But Mio and Maria’s true forms are actually the newbie Demon Lord and a succubus!? Basara was almost entered into a master and servant contract with Mio, but a “reversed” contract was formed by mistake, and Basara is now the master!?
