Eromanga Sensei Vol. 6

High school student Masamune Izumi loves writing light novels, but he's sadly lacking in artistic talent. Enter Eromanga Sensei, an artist with a dubious pen name and a tendency to draw perverted illustrations! Having always assumed that his anonymous partner must be some perverted otaku, Masamune is stunned to discover that Eromanga Sensei is none other than his hikikomori little sister, Sagiri! Join these quirky siblings as their wildly entertaining story unfolds in the Eromanga Sensei manga series.
In Vol. 6, with the training camp for strengthening his light novel over, Masamune has leveled up his skills, but Sagiri seems to be acting weird…
Notice: This manga is written in Japanese.
