Everything about this anime has a unique atmosphere which you can feel from the first episode.
Story:
Some people like to compare this anime to Stein's Gate because it involves some time travelling. Other people wondered about the mystery and crime genre and compared it to Death Note. This anime is neither of them. It doesn't revolve around time travelling as the main idea or the plot of the story. Also, it doesn't involve that much darkness and crime twist as Death Note.
It is about loneliness and friendship, courage and hesitation, evil and good, family and abuse; It is about a lot.
Art:
The art in the anime is much better than the manga. It is also somehow unique than other animes I 've watched. You will unlikely to find mistakes while watching that may disturb you. The art is very well done.
Sound:
It just got me in the story. I didn't feel that there is a SOUND being played. I just felt the story going before my eyes while I am feeling it.
Characters:
I felt the characters as they're real. Actually, I think the characters are taken from real persons. The characters, their backgrounds, feelings and complications are very well put. You can watch the character grow up and evolve as you march through the anime.
Enjoyment:
YOU WILL NEVER GET BORED WATCHING THIS ANIME.
Overall:
I gave this anime 10/10.
