ASCII Media Works has published thirteen volumes in the series under its Dengeki Bunko imprint from December 2013 to August 2022.

Having no artistic skill himself, Masamune always gets his novels illustrated by an anonymous partner using the pen name "Eromanga",[2][3] who is known for drawing questionably perverted images despite being extremely reliable.

In addition to balancing his passion and school, Masamune is also stuck with taking care of his only family member—his younger stepsister Sagiri Izumi.

However, when Masamune inadvertently discovers that his anonymous partner has been Sagiri all along, their sibling relationship quickly leaps to new levels of excitement, especially when a beautiful, female, best-selling light novel author enters the fray.
