Eromanga Sensei

Masamune Izumi is a high school student who writes light novels. His stepsister, Sagiri Izumi, is a shut-in who hasn't left her room in years. But when Masamune makes a shocking discovery, their already awkward living situation gets even more complicated-the famous but reclusive illustrator "Eromanga-sensei," known for their risqué artwork, turns out to be Sagiri herself. Now Masamune has to grapple with the fact that his antisocial little sister is the one drawing those scandalous illustrations for his books.
