The story still using some generic isekai and waifu witch as backbone, but the author did a very good job making this manga different.
In summary, this is what you'll have if you combine Elaina and Saya no Uta. It's not the best or the most original, but it's still a good manga to look forward.
The art did a good depiction of monstrosity of the characters. Not exceptional like Berserk but not so bad that you fell sick to read it.
The major plot hole is about how the MC got isekaied, some detail are too forced and not well explained.
