The first chapter of Araburu Kisetsu no Otome-domo yo will debut in the January 2017 issue of Bessatsu Shōnen Magazine, which will be published in Japan in December 09, 2016.
Screenwriter Mari Okada (KIZNAIVER, Mobile Suit GUNDAM Iron Blooded Orphans) is branching out into manga writing as well with a new series serialized in Kodansha’s Bessatsu Shōnen Magazine magazine entitled Araburu Kisetsu no Otome-domo yo (“The Maidens of the Savage Season”).
No specifics concerning the plot of the series have yet been released, but I suspect the fact that all of the girls in key art above are holding lilies (“yuri” in Japanese) is significant.
