Junior High student Nao's brother complex is so strong, it's almost at the point of incest. She's determined to make her brother, High School student Shuusuke, see her as a woman. So determined, that she goes as far as going into his room to throw away all his non-incest related porn. But as she's looking for his porno stash, she finds a photo album... and she's not in any of his childhood pictures. What is going on?

When I first saw the announcement of this title I was pretty disgusted. Another incest title? Really? Doesn't Japan ever get sick of this crap? It makes me fear for the well being of all of Japan's imouto's if this disgusting sentiment is so widespread that it can sustain a substantial subset of the anime programming lineup. However despite my reservations and do to my own morbid curiosity with anime train wrecks, I decided to give Onii-chan no Koto nanka Zenzen Suki Janain Dakara ne!! a try.

The first thing that one is going to notice is just how completely ugly read more

Light spoilers.

I honestly don't think this anime was too bad. I mean, why would you watch this show if you had something against incest? I don't like it in real life, but in anime it's okay, imo. But it states in the first episode that they aren't blood-related, and that the sister was adopted.

The story wasn't anything new. A girl's crushing on her step-brother, he has a childhood lover who wants him, and some cute girl also likes him (and at the end a cosplay-obsessed girl tries to steal his heart). I find this on the unrealistic side of things because he's commonly referred read more

"For what shall it profit an Otaku if he should find the worst anime in the whole world, and lose his own sanity?" - Book of Weaboo 8:36


A few weeks ago, I asked my friend what the worst manga he had ever read was. He answered without hesitation that it was a manga called "I don't like you at all big brother!". I decided to research this title and discovered to my utter terror that this manga actually was popular enough to receive a 13 episode anime adaptation. I watched this anime on my laptop during a 5 hour car trip. I weep read more

Incest is a touchy subject, deemed morally wrong by the general populace. Luckily, this anime throws that concept out the window, so it's a lot less awkward for the viewer. (Though still quite awkward. :x)

Onii-chan no koto more or less, deals with three girls who like the same guy for the wrong reasons. The plot in itself, isn't anything special, being more or less, your standard ecchi comedy. The humor usually didn't cut it for me, though it had a few chuckle moments. The one thing that separates Onii-chan no koto from other ecchi comedies would have to be the main girls themselves.

Nao, the main read more
