Story: Ok I gave the story a 9 because there really isn't exactly a story it's basically a bunch of adventures (side note: I would probably watch Full metal Panic before watching this so you can understand the background better) but their good adventures, I loved it.
Art: I gave it a 10 because everything looked real and real life.
Sound:10 didn't find anything wrong with it..the theme song is also very good
Characters: I loved all the characters personality ! Their all awesome
Enjoyment : I laughed sooo much this is the funniest anime ive watched so far
Overall : If you have a good sense of humor you will love this anime ! I loved it and laughed and enjoyed myself soooo much. I wish they would've made more than 12 episodes. Hope you love this anime as much as I did :)
