Eromanga Sensei

エロマンガ先生

High schooler Masamune Izumi writes light novels but cannot draw, so his books rely on an anonymous illustrator known only as Eromanga, whose work is reliably skilled and reliably lewd. At home he looks after his only family, his shut-in younger stepsister Sagiri, who never leaves her room. The two truths collide when Masamune realizes that the elusive Eromanga he has worked with for years is Sagiri herself.
