I'm not saying that this show is bad, its good, but its missing key components.
Story: 7/10. The general idea of the story was very good but the beginning was rushed and the character development for Akira ended quickly
Art: 1/10. The art was lame. It may be good to some people, but I prefer more detail rather than art that looks like it didn't take much time.
Sound: 3/10. Average soundtrack and the theme song was bad/weird.
Character: 7/10. The main characters are complete opposites which works great with the story. The other characters are good as they are really unique.
Enjoyment: 3/10. I felt like I had to force myself to watch this at some points as some episodes were boring. Also, why does Ryou have boobs at the end. This made no sense.
Overall: 3/10. Don't recommend.
