That anime looks fucking bad ass! Blood gore, sex, jealousy, love, stalking. what is it called?
Oh no. You won't find any of those things that you've said in the actual anime. The editor just did a fucking fantastic job to alter the mood of the anime. (copypasta from youtube comments so sue me)
Anyway, it's Ore no Imouto ga Konnani Kawaii Wake ga Nai, a romance-comedy anime.
