Who is Oshino Ougi?


This question contains spoilers for the second season of the Monogatari
series.

Oshino Ougi refers to herself as the niece of Oshino Meme. But Kaiki mentions
in Koimonogatari/Hitagi End that Meme has no family at all and it's not
possible that he has a niece.

Also, [this news-article at
ANN](http://www.animenewsnetwork.com/news/2014-03-12/owarimonogatari-final-
novel-promo-streamed) suggests that she ([or
he?](http://bakemonogatari.wikia.com/wiki/Ougi_Oshino#Trivia)) fights with
Koyomi in the latest novels and it seems to me that she is responsible for
Nadeko becoming a god. Is she actually an antagonist?




Ougi’s true identity is Araragi Koyomi himself. From the Bakemonogatari
[Wikia's](http://bakemonogatari.wikia.com/wiki/Owarimonogatari) section on
"Ougi Dark":

> Gaen reveals that Ougi’s true identity is Araragi Koyomi himself. She is an
> Oddity that Araragi created, similarly to how Hanekawa’s stress created
> Black Hanekawa, and Sengoku’s hallucinations created the white snake
> Kuchinawa. Ougi represents Araragi’s self-criticism. When Araragi saw
> "Darkness" for the first time in Shinobu Time, he realized that there is a
> law dictating over the world of Oddity. Araragi knows that he is too weak,
> too hesitant, too emotional to make harsh decisions, and he subconsciously
> wished for a being that can judge him, and "correct" everything wrong in
> this world. His desire came true as Oshino Ougi.
