Didn't really like the beginning of the series. The whole Fumina arc bored me. The second half of the series was great though. Even if we didn't get to see "you know what". I really would like a third season. (can't get enough of Shana lol)
I love both OP and ED songs, BGM is good and the final insert song is great.
The season would get a 7/10 from me, but since it's Shana: a solid 8/10
