Kyousuke Kousaka, a normal seventeen-year-old high school student, hasn't gotten along with his younger sister, Kirino, in years. For longer than he can remember, Kirino has ignored his comings and goings and looked at him with spurning eyes. It seemed as if the relationship between Kyousuke and his sister, now fourteen, would continue this way forever.
One day, however, Kyousuke finds a DVD case of a magical girl anime entitled 'Hoshikuzu Witch Merle' (Stardust Witch Merle), which had fallen into the entranceway of his house. To Kyousuke's surprise, inside the case is a hidden adult video game titled 'Imouto to Koishiyo!' (Love with Little Sister!). Kyousuke attempts to fish out the culprit who dropped the case by bringing up the topic of magical girl anime at the family dinner table. All that comes out is a strong negative reaction from his parents, especially his anti-otaku policeman father.
That night, Kirino bursts into Kyousuke's room and, in perhaps the first conversation she has initiated with him in years, says they "have things to talk about." Kirino brings Kyousuke to her room and shows him an extensive collection of moe anime and lolicon bishoujo games she has been collecting in secret.
I seriously don't know what the big deal is with this series. Other than the character design of Kirino, everything else is completely bland and plain. Manga may not be as popular as anime, but Hell, it isn't much better either.
EDIT: Who the Hell put the shounen tag on this?! Jesus Chri.. -.-
It is very unstable. At the beginning, you're pretty sure it will tell us a nice story about how a distant brother and sister got to respect and love each other like any family should, but there is so much jealousy, tsundere, cute/fanservice scenes all over it, I can hardly take
it seriously. This is BARELY a seinen. In fact, it isn't. It is supposed to be ABOUT otakuism, more realistic, while it itself draw attention of so many otaku and loli fans.
The art is downright catastrophe. Of course, the character design is bloody cute, and Kyousuke, the main male, looks OK, but that is all there is to it - not to mention all the girls, basically, look the same. They are all adorable.
Aside from that, the surroundings are disaster, the detailing is nonexistent, and it pretty much looks like a somewhat better looking shoujo one shot.
The characters are so stupid. The only reason why this is a 4 is because Kyousuke isn't THAT typical of a character and is in fact good looking, smart average student and is actually doing many things out of his way just so he can actually get to know his sister. Which also pulls the question of why is he considered repulsive by Kirino. No Kirino. Just no.
Speaking of Kirino... ehh, she is a selfish, stupid, childish tsundere. She is worse than Suzumiya Haruhi. She is so tsundere it is painful.
Her best friend is normal at first, but in fact quite a psychopath.
I enjoyed the beginning, as it looked promising, but as it went, it just became more obvious all of this whole manga is a "seinen" excuse to draw adorable girls, and make tons of money on it.
It is a very deceiving manga. Just as you thought you could get deeper into a story about relationship progress between two siblings, you realize it is as shallow as a bad made 13-episode ecchi series. Only it is not ecchi. But it isn't seinen either. It is almost shoujo.
