This manga is focused on martial arts, but is just as solid in other aspects as well. The martial arts aspect is reasonably well done, wherein the fights look pretty good and everything seems to flow well, though it doesn't go into that much depth with a couple exceptions. The characters were also super interesting and amusing as well.  Onodera straddles the line between arrogant and confident well, having faith in his own abilities and even showing off sometimes, but he isn't someone that gets overtly angry or pathetic when he actually loses. Rather he accepts it quickly, and goes from there, pushing forward to improve, even if he has to bow his head to do it. Hence, I really liked him. Asato is also quite cool, in that she's a teacher, but as is rare for mangas such as these she isn't a haughty one at all, rather she seems to get along tremendously well with Onodera. Akane on the other hand, was a good amount arrogant I would say, which resulted in a personality clash with the other two, which resulted in things never really going her way, which was amusing and ultimately resulted in some growth towards the end, which was interesting to see, even if it was super rushed. And that's where we get to the biggest issue in the manga, the ending being ridiculously rushed. In terms of character growth and development, it did show some for Onodera in a way that was cool, but still felt far too rushed. On the other hand, in terms of his relationship with Asato, it's even worse, in that it doesn't seem to reach any sort of conclusion at all, which was incredibly unsatisfying. And in terms of plot, the ending is so abrupt, that upon reaching the final page, it gives a very strong feeling of "That's it?", which is rather unfortunate because I really did like where it was going. The art was really great. 

tl;dr: A martial arts focused manga with interesting characters and great art, but a ridiculously rushed ending.
