Eromanga Sensei is originally a light novel by Tsukasa Fushimi（伏見つかさ）. It tells a story of a light novel author, Masamune Izumi, and his younger sister Sagiri Izumi. Sagiri never leaves her room after their parents’ death, and this makes her life unknowable to even Masamune. Just when Masamune is watching a live-stream of his partner illustrator, Eromanga Sensei, he finds out that this Eromanga Sensei is actually his little sister.
