I sincerely think this manga is a masterpice and deals with the psyche and soul of humans in ways no other manga does. I actually registered on this website just to write this review.

In other manga, the characters are super brave, never lose, never are really emotionally scarred (and when they are, the main character can cure anything just by saying a few words and screaming some BS about being brave or something) and all characters are sexually dead - like the people who write manga can't deal with anything but violence and rivalry (naruto, bleach, death note and even the heavier ones- like monster and liar game don't deal with subjects like this) Inuyasha for example has like 600 chapters not dealing with this.

The characters are so believable it's amazing. The characters aren't idealistic hypocrites and usually when you think they should just do something, they do it.

The art is stunning from the first chapter.

BTW, if you don't like the few parts with science talk, you can skip it - it's not crucial to understanding the storyline.
