After reading 5 volumes (24 chapters), I can say this manga is really good. First of all don't judge this manga on its first 40 pages. I had been disappointed and I had left it aside. It's by seeing very positive reviews that I gave the manga a chance again. So I read the whole volume 1 (4 chapters) and I loved it. There are 4 main characters but the real protagonist is Sasae Hatsushima: an anti-hero who presents himself as an ordinary young man unlike his sisters-in-law and his mother-in-law. But in fact it is a facade because he will quickly reveal himself as a Machiavelliangenius. We could compare him to Light Yagami (Death Note), Lelouch (Code Geass), Griffith (Berserk) etc... but as different as they are from each other. Sasae loves his "family" (not related by blood tho)

The beginning of the story is a common Dark Fantasy isekai, there is violence, sex, rape and rampage. Some hideous monsters that must be faced by those who have summoned the Hatsushima family. And it is in this scenery that the Sasae will rise.

The drawings are also very beautiful. Really a nice surprise.

Excuse my english.
