Where does Oreimo come from?
Oreimo is short for Ore no Imōto ga Konna ni Kawaii Wake ga Nai, which is also sometimes shortened to Ore no Imōto. In English, the title is often translated as My Little Sister Can't Be This Cute.
Oreimo began in 2008 and ended in 2013, running for twelve volumes as a “light novel” series. Often centered on middle- or high-school students, light novels are generally short novels of about 300 words, usually illustrated in a manga style. They are frequent sources of anime (animated) and manga (comic) adaptations. Oreimo was no different in this respect. It first received a manga and then anime treatments between 2010–13, which likely helped popularize it outside Japan.
The series centers around Kyousuke Kousaka and his sister, Kirino. Kirino is a student with perfect grades and a side-job modeling. But despite her outward talents and virtues, Kyousuke discovers that she has a secret fondness for erotic anime and video games. To maintain her reputation, and to avoid her parents’ disapproval, Kirino swears him to secrecy, and he becomes her accomplice in her other life.
The series is controversial for themes of brother-sister incest, and its ending, which suggested that Kirino and Kyousuke planned to enter into a short-term romantic relationship. Some fans were upset by the intimation of incest, and others by the fact that Kyousuke ended up without any long-term romantic prospects.
Oreimo is the source of a meme called Oriemo Cover Art Parodies. The light novel’s first installment had an illustration of Kirino standing with her arms crossed and a stern expression on her face, while Kyousuke looks on from behind. The parodies usually involve two characters in similar poses with some variation of the snowclone (verbal formula): “My Little X Can’t Be This Y,” derived from the English translation of the title.

“The set is a collaborative effort between Oreimo and three companies, all interested in making sure your special day goes off without a hitch. Or, perhaps, with a hitch.”
