Have you ever loved your older brother (or another sibling, if you have one) so much that you just want to do this and that to him? No? Well, if you're Nao Takahashi, your answer would be "yes". I first heard about this anime when I saw the manga version in a catalog from RightStuf, and I became intrigued to watch the anime when I found out it had one. Even if it's poorly received, and even if the characters are unbelievably skinny, this anime could turn out to be quite charming, right? The answer to that question, unfortunately, is "no".

Now presenting my review of "Oniichan no Koto Nanka Zenzen Suki Janain Dakara ne!!", or "I Don't Like You At All, Big Brother!" in English.

Onisuki, as it will hence be referred to, follows Shuusuke Takahashi, who has a little sister named Nao. Nao has a HUGE brother complex, going out of her way to give her already perverted brother some sexual excitement. One day, Nao discovers that she was actually adopted, seeing this as a chance to try to win her brother over. Unfortunately, Shuusuke's childhood friend, Iroha, and class representative, Mayuka, are also in the running for winning his heart. With all of this being said, let the sexual innuendo commence!

The story is rather boring, with its clusters of cliches and lack of real character development. The characters themselves aren't that great, either; in fact, they are what bring this story down for the most part. First, you've got Shuusuke; he's like Issei from High School DxD, except Issei actually has some redeeming qualities, while Shuusuke, in my opinion, does not. All three girls in his harem are even worse than him, though; they are all messed up in their own ways. Mayuka seems to be the tamest of them all, but not by much; she has an obsession and a certain part of Shuusuke that I will not reveal in order to avoid spoilers. Then, we've got Iroha, his REALLY clingy childhood friend who watches him through a telescope at her own house. Nao is similar in the stalking aspect, but she also purposely gives him some time to look at her in a perverted way before harming him in some way. Seriously? Nao has a sick mind, and I don't mean that in a good way!

I wouldn't say that the voice acting is bad, considering that there are talented seiyuus like Eri Kitamura and Marina Inoue being a part of the cast. However, I'm disappointed that those seiyuus would waste their talent on something like this. I honestly didn't care about the opening or ending themes. However, the biggest problem to plague Onisuki is, of course, THE ANIMATION. I could barely focus on whether or not the animation from Zexcs was any good; I was too busy cringing at the character designs. I mean, you've got skinny, and you've got Clamp-skinny; however, the skinny-ness of this anime sets a whole new bar. Seriously, are they all anorexic?!

Overall, Onisuki was just a pain to watch; I have no idea how I was able to pull myself through it. If three probably-anorexic, insane girls fighting over a probably-anorexic, perverted boy is something that sounds appealing to you, I guess you could give this a try. I honestly can't imagine someone who would think that, though, especially considering that this is an incest anime.
