I read all the volumes, I really enjoyed the 161 chapters, the art is beautiful, the characters are endearing, some of their adventures are certainly negligible, but these make us discover a little more about these characters all the same. It's a 8 for me.

But wait a minute... There are 162 chapters and not 161? The 162nd doesn't exist, come on! If? Oh, let me check... Oh no... There is a 162nd chapter...

This 162nd chapter has made me assign only 4 to this manga (instead of 8 or even 9). I mean, when you write a story, there is the introduction of the characters, the adventures etc...
In To-Love-Ru there are all the elements that make the story almost awesome (A L M O S T). Because when a story is coming to an end, we must have a conclusion, we must know who Rito will choose at the end of the story. 162 chapters is very long, and at the end of this story, we are entitled to a """conclusion""" that leads to a sequel ("To-Love Ru Darkness" that I have not read and that I will not read).

That's why To-Love Ru is objectively worth 8 (even 9), but subjectively 4.
It's a really captivating manga, I recommend it to you, but if there's a sequel, it's because you already know the outcome of these 162 chapters....
