Himenokouji twins Akito and Akiko have finally reunited with each other after separation due to the death of their parents. After six years of living apart they suddenly began to live under the same roof due to Akito's desire to live as a family unit once more. Things were fine at first until Akiko began to express her incestuous love for her older brother, who only sees her as a little sister.

"At the end of the day, at the end of the day when all was for naught, I can at least take pleasure in knowing that my little sister is waiting at home with open arms and a warm bosom." — Sophocles

Since the Armory Show of 1913, the state of Western Civilization has been one of decline. Though the rise of Modernist Art might not seem terribly significant to the average uneducated reader, the paradigm shift from Representational Art to Abstract Art planted the Seeds of Degeneracy that sprouted into the base and rotten Popular "Culture" that we are all so familiar with today. Indeed, read more

Onii-chan Dakedo Ai Sae Areba Kankeinai yo ne! is one of those Ecchi-anime which happen to pop up once in a while and though there may be a ton of crappy ones, some of them at least have a decent story, or a good sense of humor, making up for the usual flaws Ecchi-anime often have.

But nope, we are out of luck with this one, meaning that this anime does not have a decent story and while we´re at it, it also lacks of interesting characters, character development and all the other stuff that make up a decent anime.

To be fair, it´s an Ecchi, read more

Tsundere Right? Follow me. I don't like you one bit. Not at all
Reply: I don't see you as a love interest one bit. Not at all.
That wasn't Tsundere!

Every anime has its own priorities, or goals. If every anime was aiming for the same thing then there would be little variety. Shounen anime like one piece or naruto are meant to make the watchers enjoy awesome fights and power ups through a long adventure and Key productions such as Clannad and Angel beats are meant to be a romance story that could make a grown man cry.

OniAi(this anime) does not aim for a romance or action. read more

Guilty pleasures...things you know are bad but like them regardless. This show would have to be one of my biggest guilty pleasures of 2012. So generic, so predictable, yet funny and entertaining at the same time.

Onii-chan Dakedo Ai Sae Areba Kankeinai yo ne, or OniAi, is yet another fan service heavy romance anime. An incestuous tale about about a high-school girl who, after six long years, finally gets to see her beloved brother. After some random unexplained developments, the story develops into a harem in just the first episode.

From there, the plot becomes extremely predictable to the point of just being plain sad. read more

Anime: Ore no Imouto ga Konnani Kawaii Wake ga Nai
- Both a story about a brother and sister where one wants an incestuous relationship
- It's not as blatant, but the art is similar as is the storyline
- Incest relationship without harem

Anime: Kono Naka ni Hitori, Imouto ga Iru!

Both involves brocon.

Both have a the same harem, comedy and school genre.

Both involves the harem who wants to pop the guy's cherries.


In one anime the guy has to find out who among his harem is his sister, while in the other anime the guy knows who his sister is.

The guy in one anime is filthy rich, while the guy in the other anime has to run the dormitory to earn a living.

The harem in one anime lives with the guy, while the harem in the other anime lives away from the  read more

Anime: Inu to Hasami wa Tsukaiyou
In OniAi the male lead is a popular author who uses a pen name and the female lead is a big fan of his writing.

The concept is switched around in Inu to Hasami, where the female lead is the author and the male lead is the reader.

Anime: Kiss x Sis (TV)
Comedy and fanservice based around brother-sister incest.
OniAi takes a more harem-oriented approach while KissxSis focuses much more on the sisters.

Both are based on the premise of the sister(s) lusting after the brother, with the brother resisting with varying degrees of success. Both also feature an older girl (teacher, editor) who tries to correct what she sees as deviant behavior, also with varying degrees of success.

Anime: Mayo Chiki!
Romantic-comedy-harem with very little plot.
Extremely similar character designs and art (notably, Anastasia and Usami, Gin and Subaru).
Kitamura Eri.

Both look very good and deliver nicely on fanservice and relatively lowbrow comedy.
