I am someone who first watched the anime and then reverted to manga. And the only thing I experienced was pure enjoyment both the times. Even the Chapters I had already watched over in the anime gave the same taste of Enjoyment as they gave off in the anime. This series is truly worth for what it's genre are "Best Harem Development", "Best (Accidental/Or Not) Ecchi stuff", "Best Romance", "Girls", "Comedy at it's Best".
Damn it the Monster Girls have been so well described and their habits too. It almost seems like the real animals. The author has really blended the animal instincts/behaviour pattern, their features, powers everything in the girls. My point was that the author really did a lot of research for developing this masterpiece. If you wanna read it just go for it without a second thought.
Peace out.
