Fushimi, Tsukasa

High school student Kyousuke does not get along with his fourteen-year-old sister, but when he finds out her secret, he wonders if they may become friends.

"It's summer in Japan, and Kirino is back, which can mean only one thing...everyone's second trip together to Comike, the world's largest fan convention. Kuroneko's got a stack of her self-published comics to sell, when who should they all bump into there but the lovely, talented male model Kouki Mikagami...who's been in a photo shoot with Kirino...?"--Back cover frame.

Despite her hateful attitude toward him, Kyosuke goes out of his way to defend his sister Kirono's collection of anime DVDs and erotic video games and to keep her secret from her mean-girl friends.
