I watched the anime and read the manga but never read the LN. Having taken an interest for so long I finally read the LN. Honestly, the ecchi is quite good. I don't know why some reviewers say it's not good to read LN when it comes to ecchi. But, if you have good imagination, ecchi isn't a problem.

The story doesn't start off too complex. The main character is a former member os the hero clan and his two addoptive sisters are from the demon clan. The main character wants to protect his family, and so they enter something called a Master-Slave Contract in ...
