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 Meruru (Stardust Witch Meruru), 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.

People can look at this anime anyway they want, but it'll forever be (for me) a sweet story of how an older brother came to love his sister as any older brother should. So far, every episode managed to unfold into how the two get closer to each other as the older brother helps his sister with common teen problems.

The story is different from other brother-sister relationship anime. Told from the brother's point of view, it's light and has no weird physical and romantic interaction between the two. I like how he started from not even talking to his sister to how he realizes read more

Every season we seem to get that one show that has all the buzz and word of mouth about it from the anime community. This time most of that was centered on this anime, Ore no Imouto ga Konnani Kawaii Wake ga Nai. I will admit that from the first time I saw details of this show pop up I was not to thrilled with its prospects, but the hype over the show was too much to ignore and I decided to give it a go. In the end I am left wonder just what was all the fuss about?

'Ore no Imouto ga Konnani Kawaii Wake ga Nai' (Long titles for the win) is one of those animes I just can't figure out. On the surface it appears to be an anime about a brother and a sister who struggle to realise their feelings for each other. But in reality it is about much more than that. We have a good chunk of the story here focused on anime and the world of otakus as well as the friendships that one can gain simply by going outside and meeting new people.

That said, the plot's main purpose is to of course present us the read more

This anime was a pleasant surprise. It has an interesting take on the bro-sis relationship. The two siblings treat each other like most do in the real world, with dislike, indifference, hate and of course love. It has an intriguing plot to begin with and as the story unfolds it actually makes you care about the characters.
I found the characters refreshing and liked how they seemed to change as the story advanced. Most of them seemed to be more well thought out than your usual 2d run of the read more

Anime: Nogizaka Haruka no Himitsu
In both anime a 'perfect' girl hides her anime-otaku hobby and is discovered by the male protagonist (Nogizaka: classmate, OreImo: Brother) who will support her and start exploring the subculture.

Anime: Boku wa Tomodachi ga Sukunai
These two are so similar that the OreImo cast made a 'from behind' cameo appearance, in episode 11 of Boku.

Kirino and Sena are the same character... breasts aside. Their spoiled princess attitudes, erotic game addiction, prideful arrogance getting in the way of friendship and fangs are NEARLY IDENTICAL. What's more, Kuroneko and Yozora ALSO MIRROR EACH OTHER--sharing 'bickering love' friendships with K&S respectively. They argue CONSTANTLY when together, oblivious to the how similar their personalities are. The only difference of note in the relationships between the shows is that Yozora clearly has the upper hand against Sena--often forcing her to run away, crying.  read more

Anime: Suzumiya Haruhi no Yuuutsu
Male protagonist and storyteller, while the story is actually about a tsundere girl who walks over them and terrorises them. Both guys are cynical and comical, without them realising it.

Anime: Watashi ga Motenai no wa Dou Kangaetemo Omaera ga Warui!
Watashi is the OreImo only reality can offer. What this means is Watashi's sister heroine isn't beautiful, isn't an athlete, isn't at the top of her class and just generally doesn't have the world at large fawn over her. In OreImo acting bitchy whilst having a sexual fetish typically associated with fat otaku men is rewarded, and the icing on the cake is a doormat brother willing to do anything to appease her--incest not withstanding.

OreImo delivers as far as entertainment goes. This is true. But after following Kirino's tsundere self down the road toward incest for long enough, it makes a nice  read more

Anime: Lucky☆Star
Both are about otaku girls and their friends and family- though there's more drama in OreImo, and Lucky Star is a lot more easy going
