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 youre 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 its 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 Dont 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 Shuusukes 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 arent that great either in fact they are what bring this story down for the most part. First youve got Shuusuke hes 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 weve 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 dont mean that in a good way I wouldnt 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 Im disappointed that those seiyuus would waste their talent on something like this. I honestly didnt 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 youve got skinny and youve got Clampskinny however the skinnyness 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 probablyanorexic insane girls fighting over a probablyanorexic perverted boy is something that sounds appealing to you I guess you could give this a try. I honestly cant imagine someone who would think that though especially considering that this is an incest anime.
