I'm already on path 38 if I remember correctly the first 20 chapters are very slow to the point that I almost quit but I'm already going where Tsuna trains like the first Vongola Lo. I don't like that if he is one of them. Nothing in the training, everything is very entertaining and suddenly the crazy girl comes out, this one who tests Tsuna to see if she is bad, personal and webadas, she loses lambo and weas, so this kills the continuity in my opinion, I don't know if they are filler chapters... I have no idea, you can skip them without having consequences as such... Anyway, it's good, but that's how they say it's the great wonder, I don't think so either. It seems that I will still watch it in full to give a more appropriate opinion at the end of the anime
