Description:

“Hey, you said you wanted a little sister, right?”

First year highschool student, Toujo Basara, was suddenly asked this question by his father, and he fell into a state of panic. On top of that, the eccentric father told him that 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 a newbie Demon Lord and a succubus!? Basara was almost forced into a master and servant contract with Mio, but a “reversed” contract was formed by mistake, and Basara is now the master!? Moreover, Basara is being hit by ecchi situations one after another due to the contract, but Mio’s life is being pursued by other demon tribes and hero tribes!!

The most powerful contractor’s desire action drama begins!

Notes:

• First three volumes have the official colored illustrations, the rest have the normal grayscaled illust.
• Available SS are included in their respective volumes.
• I've only compiled what's publicly released by the translator, I may update if I could get my hands on the rest of the translated content (EX II, EX III, and Volume Light!).
