Assassination Classroom Spin-Off Manga Announced

Earlier today we posted about the second season of Assassination Classroom being scheduled for January 2016, but that’s not all that’s in store for Koro-sensei and his would-be killer pupils. There’s also a spin-off manga on the way, with Koro-sensei Q! set to launch in the November issue of Shueisha’s Saikyō Jump magazine this Friday.

Koro-sensei Q!—in which the exclamatory “Q” stands for “Quest”—comes from Kizuku Watanabe and Jō Aoto. According to the magazine’s tease, the start of the manga will see Koro-sensei becoming a “demon king.”
