Let me start by giving description of each aspect:
1. Story: 8
Its starting is slow and seems boring but it rapidly picks up pace and its ending makes up for its start, rather more than makes up for its start. I liked season 1 and this show has never let me down. The former half was a bit boring and the latter half is outstanding, so I will give it an 8 for story.
2. Art:9
This show never disappointed me when it came to art work. The world building and the graphics are superb, from the beginning to the very end. Therefore I will give it a 9 for art.
3.Sound: 9
Sound effects are what drew me in to this show when I started watching its first season and it has only transcended its own limits and has never been a let down. A 9 for sound effects.
4. Character: 9
Character design are all magnificent, in fact the portrayal of my favorite character was done as I was expecting it to be, I have no complaints with the character design. Therefore a 9 for character.
5. Enjoyment: 9
I thoroughly enjoyed the show, from the story plot to the op characters to the character design, it was a show worth watching and am eagerly waiting for the next part of the show.
Overall: 9
