This is a very unique manga with amazing, tranquil art. I've never come across a story with such an interesting plot, and was enchanted. I can't say I loved it, however, because of a few things. One, it doesn't feel as short as it is. Although its only about forty chapters, the slow/relaxed pacing makes it feel longer. I also have to admit that there are quite a bit of chapters that talk about scientific topics that I found hard to follow. The art truly is so beautiful and this is storyline that you'll probably never come across elsewhere in terms of manga, so Ido recommend giving this s read.
