The December 2015 issue of Kadokawa’s Dengeki G’s Comic magazine has revealed that the Sword Art Online anime film’s all-new original story will take place after the Mother’s Rosario arc, which was the final arc depicted in the television anime’s second season.

The Mother’s Rosario arc in Reki Kawahara’s original light novel series covers Volume 7 of the series. The second half of the anime’s second season also covered the Calibur arc, which took place in Volume 8 of the light novel series, but aired in the second season before the Mother’s Rosario arc.

Kawahara is writing a new story for the film. Tomohiko Ito is returning from the two television anime series and the anime special to direct the film at A-1 Pictures. Shingo Adachi is also returning from the television anime to design the characters.
