The November issue of Kadokawa's Dengeki Maoh magazine revealed on Wednesday that Michiru Katō will launch a new manga based on the The [email protected] SideM game in the magazine's next issue on October 27. The manga is tentatively titled The [email protected] SideM Struggle Heart, and the magazine hints that the manga will be about "battle and musicals."

The main The [email protected] SideM game launched in July 2014, and is available for iOS and Android devices, as well as on Mobage and ChromeApps. The game has more than 1 million downloads. Like other The [email protected] games, SideM is built on the concept of "idols you can produce." The app focuses on the male idols at the agency 315 Production (pronounced "Saikō Production" or "Ultimate Production"). Another app, The [email protected] SideM Live On [email protected], launched this year.

Katō ended the The [email protected] SideM Dramatic Stage manga in Dengeki Maoh on June 27. Kadokawa shipped the manga's third and final compiled book volume in August.

The game's anime adaptation will premiere on October 7. A prologue special about the three Jupiter idol unit members will air on September 30.

Sumeragi's The [email protected] SideM Riyuu Atte Mini! spinoff manga is still running in Dengeki Maoh.
