Story has a 3 because it has nothing interesting. It is just a plain story in which the protagonist agonizes while pursues really strange girls.
Animation has a good score due to not only the animation that can be watched at the majority of the time in the anime, but also because of the change of drawing in specific moments to highlight every "goddess" of it.
I liked the soundtrack, but I think that the OST during the anime was better than the opening and ending. Although they are also good, are not those that captivate you at the first time you hear them.
Characters: I disliked especially Touya because of his weakness against the provocation of Yayoi, and at the same time I admired the willpower of Yuki.
So, the overall mark is 6.5. Watch it only if your life depends on it!
