Dengeki Bunko has revealed that the latest work from Tsukasa Fushimi (best known for writing Oreimo), Eromanga Sensei, has been green-lit for an anime adaptation. No other details about the adaptation such as release year or the studio working on the anime have been revealed.
A description of the story is provided by ANN:
The “new sibling romantic comedy” revolves around Masamune Izumi, a light novel author in high school. Masamune’s little sister is Sagiri, a shut-in girl who hasn’t left her room for an entire year. She even forces her brother to make and bring her meals when she stomps the floor. Masamune wants his sister to leave her room, because the two of them are each other’s only family.
Masamune’s novel illustrator, penname “Ero Manga Sensei,” draws extremely perverted drawings, and is very reliable. Masamune had never met his illustrator, and figured he was just a disgusting, perverted otaku. However, the truth is revealed … that his “Ero Manga Sensei” is his own younger sister! To add to the chaos that erupts between the siblings, a beautiful, female, best-selling shōjo manga creator becomes their rival!
Eromanga Sensei is written by Tsukasa Fushimi and illustrated by Hiro Kanzaki. Tsukasa Fushimi launched the new light novel series after finishing Oreimo in 2013. Eromanga Sensei is published by ASCII Media Works under their Dengeki Bunko imprint.
