Eromanga Sensei (2017)

Synopsis

This "bro romantic comedy" is about Masamune Izumi, a light novel writer in high school. Masamune's younger sister is Sagiri, a quiet girl who has not left her room for a whole year. She even forced her brother to make and bring her food while she stepped on the floor. Masamune wants his little brother to leave his room, because the two of them are each other's only family. The novel illustrator Masamune, pen name "Eromanga", draws very perverted pictures, and is very reliable. Masamune had never met the illustrator, and thought he was just a disgusting perverted otaku. However, the truth comes out... that his "Eromanga-sensei" is his own little sister! To add to the chaos brewing between the siblings, a beautiful, female, best-selling shoujo manga creator becomes their rival!
