Wednesday, September 9, 2015
This day is covered in these episodes:
This date is a guess, the events happen sometime in September.
Another scenario meeting. Assuming that a few days have passed, since Midori prints out the first draft of the final episode later this day. The meeting and her printing the scenario likely happen on the same day, since Midori, Aoi and Hiraoka outfits do not change between the scenes.
