It was announced on a live presentation by Kadokawa on Friday that Elf Yamada of the series Eromanga Sensei will have her own spinoff manga slated to be released on July 27 in the September issue of Monthly Comic Dengeki Daioh Magazine. This will be the first spinoff series for the Eromanga Sensei franchise.
The light novel series was first released in 2013 after the creator Tsukasa Fushimi finished Ore no Imoto ga Konnani Kawaii Wake ga Nai light novel series. Both the series are illustrated by Hiro Kanzaki. The ninth volume of the Eromanga Sensei was released on June 2017.
The manga adaptation of the series launched in 2014 is still on going and is released in English by Dark Horse Comics. Its popularity has also paved way for an anime adaptation which was aired in April 2017. Blu-ray Disc releases for the anime are also in the works.
Synopsis (by Dark Horse Comics):
Writing light novels isn’t all that easy, especially when you’re in high school…and you have to do the cooking and the chores for your shut-in stepsister who’s hardly come out of her room the past year! In the light novel business, it’s crucial to have the right person illustrating your books to help them sell—and maybe get made into manga and anime! But in a world of online pen names, the author and the illustrator may still not even know each other…until one day they realize they’ve been living in the same house all along! Now the home life of confident writer Masamune Izumi and his reclusive sister Sagiri—aka the artist “Eromanga Sensei”—will be a drama to compare with their rising careers, their restive fan base, and their rivals in the industry!
