“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!

Well if you like shounen and typical MC which is the type to never give up and protect all etc this is for you. MC is strong but not overpowered.
Spoiler

Also there are lot of scenes bordering on hentai. Each girl has their own separate arc where he saves them.

In general this is a typical shounen slice of life harem anime with your average MC. Well a special point about MC is he is not afraid of killing.
Spoiler

He killed zelrog or some1 I forgot the name by giving him to some other guy to torture and then came to see himself while the other guy killed him. That was fun

[collapse]
Its fun to read.

This is a great fan service/action novel and continues to improve as time goes on. But if your not interested in fan service (even if its the most well done I have read) then this is obviously not for you. There is also a good anime adaption.

Fanservicey to the point that the novel literally spends a large portion of pages (probably 20% at least per volume) talking about fanservicey nonsense.

There's an underlying plot, but frankly it's annoying wading through the all the nonsensical bs to get to the plot. The rating might be slightly harsh but that's primarily because I personally feel annoyed with how slow the plot progresses not due to additional character building but rather needless s*xual gratification.

We get it, he's surrounded by pretty girls and most of them want to be his slaves.... more>> Stop writing a paragraph about it every chapter and maybe the novel's pacing wouldn't be completely horrible. <<less

Fantastic novel and plot. Always loved the Angel, Hero, and Demon kind of thing. Nice action between the MC and his girls too ;)
