Katsura makes herself a b1tch becouse if she don't do that, she will lose Makoto (She will lose Makoto becouse of Sekai if she wasn' that). I don't know why or what makes Makoto to prefer Sekai and Kotonoha lose him. One day, Kotonoha makes herself a "USO DA!" girl, she taked a knife and kill Sekai.

Oh man... Poor Kotonoha...

that surely is a very shocking ending...but anyone thinks that this kind of outcome could be possible for the anime?
