On we go, so this anime isn't action or anything, rather than it's an anime based on a brother-sister relationship. Some people consider it "Tsunderes" seeing how the brother and sister start from not talking to each other to actually talking and "hanging" out more often. BUT, in my opinion, the anime title is a bit misleading. When I started watching it, I thought it would be nice to see a relationship going from bad to good and "hopefully" to best. Unfortunately, it doesn't seem that way. Trying to no spoil anything, the sister's behavior is outright bad(she treats her "older" brother like crap and brags a lot), more like a spoiled brat. Sure I can understand the first 3-4 episodes but the series is already on episode 8 out of 12 and the "sister" still treats her brother like crap. The brother who I believe the storytelling revolves around does extreme things to help his sister, and yet she doesn't do anything about it(she says thanks in one episode and that's it, don't expect anymore).
Story: The story concept is actually good, a bad relationship between the brother and his sister turning to good progressively. It has the "tsunderes" feel to it.
Art: The art style is clean and refreshing in my opinion. They try to make every tiny thing as detailed as possible, since the whole concept is trying to be realistic.
Sound: Well, the music fits certain scenes, which I'm ok with but there's always room for improvements.
Character: Well, like I said before, sister is a spoiled brat, brother tries hard to convince her that he's trying to be a good bro...sister treats him like crap for the 8 episodes released already. Trust me, this could either make you love the sister(Kirino) or hater her completely. 2 episodes where she isn't at all(or rarely appears) where actually good without the "spoiled brat" atmosphere contaminating a good story dialogue.
Enjoyment: Like said again and again you might love her or hater her. Up to you, really...
Overall: This anime had a good concept but they went too far on the relationship between bro and sis. Good try, really...
Conclusion: If you aren't sure yet as to what to do, watch the first 2 episodes, if you fall in "love" with her, then congrats finish the series. If you got pissed at her, I suggest you drop the series immediately, because the rest of the series is more or less of the same thing.
