I really enjoyed this manga. It's informative, teaching you about various martial arts, while also entertaining. Personally I found the main character very likeable, though he does fall into that prodigy trope already heavily used in manga and anime. Still, his skills improve over the course of the series. It does get a bit repetitive by the end, and I feel there was some room for improvement with some of the plot points, but overall it's a really solid manga that I really enjoyed. The ending also pissed me off a bit but, I learned to appreciate enough to not let it ruin the manga for me, though I'm not a fan of endings that aren't a bit more obvious as to what the author's intent was.
The art, while maybe looking a bit wonky or different, is really not bad. I even sort of enjoyed it by the end of the series.
