Story: The story contains unique elements and plot twists, which really grab my attention. To gain a better knowledge of the main characters, you must watch episode 0. Afterwards the anime becomes clearer. Also, there was only one filler epsidoe, and afterwards the story continues. It is pretty fast paced, and you'll end wanting to watch more:)
Art: Animations were consistent, beautiful, and bright. You can definetly tell it's a 21st century anime.
Sound:-
Characters: All the characters have unique attributes to each of them, which I really like. At first, I didn't really like the protagonist, but as you continue you'll understand her background.
Overall: I liked this anime because the story keeps on going without any weird interruptions. You'll end up loving the protagonist so much that you'll laugh and cry.
