"According to the Dengeki Fall Event on October 6, 2013, Ore no Imouto ga Konna ni Kawaii Wake ga Nai light novelist Tsukasa Fushimi will be starting a new light novel series called "Ero Manga-sensei: Imouto to Akazu no Ma." It will be released on December 10th. The main characters are a highschool light novelist who writes "Ero Manga-sensei" and his shut-in sister, who turns out to be the one who draws the erotic illustrations for his light novel (Full Synopsis). The art will be done by Hiro Kanzaki, like his previous work."
High art or not, I thought Oreimo was fun and pretty funny. I will be waiting for this.
