Oreimo,^{[Jp. 1]} short for Ore no Imōto ga Konna ni Kawaii Wake ga Nai,^{[Jp. 2][2][3][a]} is a Japanese light novel series written by Tsukasa Fushimi, with illustrations provided by Hiro Kanzaki. The story depicts high school student Kyosuke Kosaka who discovers that his standoffish younger sister Kirino is actually an otaku with an extensive collection of moe anime and younger sister-themed eroge she has been collecting in secret. Kyosuke quickly becomes Kirino's confidant for her secret hobby.
