I do not remember how I ended up watching this anime but I am glad I did! I believe it was just introduced to me by animefreak.tv . Anyway, this anime is a good comedy to enjoy because although it tries to be perv, the amount is enough for everybody to enjoy. It all starts with Kyosuke who has a distant relation with his sister. Kirino (his sister) never talks to him and she just tries to ignore him all time. Kirino is a very smart, athletic and beautiful girl who has it all. Apart of being a student she is a model and a very popular girl. One day Kirino out of a sudden calls Kyosuke to her room, Kyosuke surprised by this has no idea of what to expect. It is at this moment that this funny story begins since Kirino feels the need to confess Kyosuke that despise not caring about him she wanted to share her secret with him. Kirino is what you may call an Otaku (Otakus are very unpopular people among her circle of friends), one who is mainly attracted to eroge. Kirino has a closet full of erotic games and brother x sister type of mangas, videos and more. Kyosuke will try to help her out with her "hobby" and try to introduce her to other people like her. I laughed a lot when watching this anime and I believe many of you will too! Check it out and well for your knowledge the made 4 OVA's that started with changing the ending and they are working in a second season that was announced under the same tittle just added a period at the end.
