I watched the anime for To Love Ru back in 2015, and now, two years after, I decided to pick up the manga so that I can take a look at the next sequel before it becomes an anime.
And I have to say, I'm ashamed I didn't pick this up before. The anime was good, but the manga is also very good. The art style is great and the story is well worked. Each character has their development and we see how and why everyone got into the harem.
It's a bit short for a review, but I don't think I need to say anything else. I highly recoment this manga if you like this types of story. The anime and manga have their diferences, but I think that both versions really work well.
