Wow people are complaining on how the story works, even though they're not buying any official release. Saddening for the author and his/her publisher.
Not a jazz person but this manga really hooked me up. Also, few people on the comments are some jazz persons themselves which makes me convinced that this manga is nearly jazz accurate.
Well people are used to some stereotype manga route. You'll see this kind of pattern in some novels. Not gonna say it was too fast. But it was kinda interesting on its own.
