I really enjoyed reading Yamada and the seven witches, I read it back when it was still airing, I didn't finish back then.

After some years I rewatched its anime series and reread the manga, and finally, I could finish this awesome manga.
I really wished it could last forever just like I wish my youth can last forever.

Story:
Objectively, the author should have thought of a better way to introduce some plots, I mean there are some plots that feel like plot devices in order to extend the story, and also, there are plots that introduce plot holes, as I said, I liked the idea of extending the story but the introduction of the plots could have been better if the author had planned it beforehand.
The second thing, this story has a lot of plot twists which are impressive and keep you entertained and hooked, but some plot twists add plot holes.
Even with those bad things, the story gave great motivational messages through the characters.
Those are the reason why I gave it an 8/10.

Art:
The art is very good, it gives a lot of emphasis on the character faces, their body shape, and the background, also the way they are drawn for comedic purposes it archives it.
It has ecchi well introduced and not overused.

Character:
This is the best element of the series, there are a lot of characters, leading to a great variety of characters and developments but this also means there is no enough screen time for some characters.
That is not the best thing, the best thing is their comedy, the author really did her best to bring some of the most creative and funniest character antics and jokes, seriously I felt so happy due to their comedy.
My favorite characters are Yamada, Miyamura, Noah, Nancy, and Himekawa.

Enjoyment:
I finished the manga in one week, which means I read 246 chapters in one week, that's how hooked I was, and as I said, wish it could last forever and enjoy those little funny things the series gave me.
