Imouto Sae Ireba Ii. Vol. 1 (Light Novel)

Itsuki Hashima is a 20-year-old light novel author who is obsessed with little sisters and makes them the heroines of all of his works. Despite his strange obsession, he is surrounded by a tight group of friends. There’s Nayuta Kani, a silver-haired, blue-eyed beauty and fellow novelist who is in love with Itsuki and often visits him; Miyako Shirakawa, a classmate of Itsuki’s from college who has a bitchy appearance and has never been in love; Setsuna Ena, a genius illustrator with a butt fetish who goes by the pen name “Puriketsu” and who adores Itsuki; Haruto Fuwa, a fellow male novelist who debuted at the same time as Itsuki and is both his good friend and rival; Kaiko Mikuniyama, an artist with an underwear fetish who is adapting Itsuki’s novel into a manga; Ashley Ono, a brilliant but sadistic tax accountant; Kenjiro Toki, his drunkard editor; and Chihiro, his perfect, dependable younger “stepbrother” who is actually a girl and who takes care of the housework. Together, they have fun and celebrate each other’s successes while each struggles to realize their own dreams in this romantic comedy by Yomi Hirasaka.
