It's a decent read, but I really don't like behind the scenes MC who just creates havoc for the sake of leveling up. If you like this kind of trope, then this might be for you.
A decent read. His training arcs are better than the fights itself. But any story that deals with becoming Danzo's lackey, just gives me an ick. So, I hope this does no that route. But still, this is worth recommending.
Good sports novel.
Edit: For a cheating MC with many good templates, his templates are not fully reflected in him, or is being underutilized in the game. Even his training progress in his templates are not explained that well. I don't know if it's the author's way to make things more interesting, but it's annoying to read game fights when his team could have easily won, but ends up struggling. You can reason out that his team was not that strong, but hey, they are not useless. Anyway, the story is still good.
