Oniichan☆Control is a bi-monthly (formerly tri-monthly) manga by Yuna Kagesaki, the author of Karin.

Hirose Goushi has a huge sister complex. So huge, he moves from his home town to Tokyo to attend Myouzen University in order to escape it!

Three years later, Goushi's little sister Noa shows up and informs him that she's taking the Myouzen University entrance exam and that she will be moving in if she passed. Little does Goushi know, she has a similarly large (if not larger) brother complex.

Their neighbors are a female amateur manga artist (Takanashi) and an Otaku (Edo), who keeps to himself. Noa sees the manga artist as a threat and blackmails her to keep quiet Noa's secret crush on her brother. Takanashi has a crush on Edo but Edo doesn't like Takanashi because of artistic license of Edo's image in a certain genre of manga.
