I love everything about this anime. The look, the atmosphere, the characters, and of course, the music.
The music of this series (the selection I made, that is) is up to this day one of the most listened albums ever in my life.
The second season, story-wise, was not as good as the first one, but it was also funny, and I laughed a lot with the chapter on which Yukari rescues a little dog under the rain.
But the manga had a lot better story than the anime, I must say that.
