Aoko Sasaki launched manga based on upcoming December 13 anime film on August 16

The December issue of Kadokawa 's Monthly Comic Gene magazine revealed on Friday that Aoko Sasaki's Seven Days War ( Bokura no Nanokakan Sensō ) manga will end in the magazine's next issue on December 13.

The manga launched on August 16 in the magazine, and adapts the upcoming Bokura no Nanokakan Sensō anime film project that will open on December 13 in Japan.

Sasaki ( Jingai CP Catalogue. ) launched a different Seven Days War manga (pictured at right) in Monthly Comic Gene in April, and ended that series on July 13. Shin Hashimoto is credited with the original character designs for that manga. The manga adapted Osamu Sōda 's original Bokura no Nanokakan Sensō (Our Seven-Day War) novel.

The mystery story and social satire begins on the day before summer vacation, when every boy in a first-year class of a downtown Tokyo middle school disappears. Was it some accident? A mass kidnapping? Actually, the boys holed themselves up in an abandoned factory on the riverbed. With support from the schoolgirls, the boys start a revolution against the adults from this "liberation zone." The new anime film shifts the settings to Hokkaido in the year 2020.

Kadokawa Shoten published the novel in April 1985, and the novel inspired a live-action film starring Rie Miyazawa in 1988. The novel also spawned a series of print sequels and spinoffs that has sold over 170 million copies and has added new volumes as recently as last year.
