I have nothing bad to say about this anime. I loved it from start to finish.
I loved the friendship between the two main characters, and the music was great. I'm not in jazz, but I really enjoyed the music.
The anime left me feeling happy after watching every episode.. I still have a few episodes to go before I have completed this anime, and I am dreading it.. I don't want it to end.. but I know that if I have the time, I will be rewatching it. :)
The characters, the art, the music and everything else were great and to my tastes and liking. I would highly reccomend this anime to any anime fan. :)
