I never have written a review to a manga before and I never tought that I would write one, but after i finished sun ken rock i felt like I have to.
The art of the manga is just incredible and I liked the story overall. There was an arc which I didn't really liked but that was compensated with the arc that followed.
BUT the ending was just insanely bad (in my opinion). I felt like this manga was a waste of time afterwards. But I still give it a 6/10 because of the art and the beginning which I really liked.
