This manga is still in its very early stages, but the author has established some great characters, a good setting, and good precedent with the cleanliness of the art.
The focus is a boy named Kurogane, a no-strength hero who picks up a spirit (Hikaru no Go style), and does Kendo in his school. It is like many other sports manga in that respect. Unlike something like Prince of Tennis, it seems that the techniques shown are things taken out of real Kendo, instead of fantasy moves (also like Gamaran, which is full of BS martial arts).
I enjoyed the
first chapters of this manga, and look forward to see its progression into something that is even better. Currently, it doesn't have any very strong positives, but the fact that the mangaka has not made any mistakes yet, and has kept it relatively interesting is a huge plus in my book. My only complaint is that some characters look a little unrealistic (not befitting the style that I thought the mangaka was putting forth), but its too early to tell.
Overall, I would recommend this manga, but at the same time, there is nothing especially outstanding about it. I give it a 7 out of 10 and would say that we need to wait until 30-50 chapters in to see the real quality of the manga.
