Kirino Kousaka

Kirino Kousaka is the titular heroine of the romantic comedy light novel and anime series Oreimo, written by Tsukasa Fushimi and illustrated by Hiro Kanzaki. She is infamous in the anime fandom for being one of the popularizers of the "imouto incest" archetype seen in several other anime series. The little sister had a notable presence in the saimoe tournaments during the time period when the anime was being broadcasted. While she may have won the heart of the series protagonist, she stands a distant third to fellow cast members Ruri Gokou and Ayase Aragaki in terms of successes in the saimoe contests because of her extremely polarizing reputation.

The eponymous younger sister of Kyousuke Kousaka, Kirino is a blond-haired middle school student who is popular for her attractiveness, athleticism, and academic abilities. But behind her seemingly perfect appearance lies the fact that she is secretly an otaku who has a brother complex, and owns a collection of adult games with older brother / little sister themes. She works as a part-time model in order to sustain her hobby. Kirino's secret hobby was discovered by her brother after he finds a physical copy of an eroge game that she accidentally dropped; following that she introduces Kyousuke to the otaku world. Kirino initially demonstrates a tsundere personality towards her estranged older brother, often exhibiting a bossy and dominant attitude towards him. The two siblings gradually form a close relationship with each other over the course of the series, with Kirino eventually realizing she's in love with her brother. By the end of the story, Kyousuke rejects all of his other love interests in favor of her.

Kirino's favorite in-universe show, the magical girl-themed Stardust Witch Meruru, is featured in her appearances in the Dengeki Bunko crossover games; several of her moves involve her cosplaying as the eponymous character.
