I see two likely possibilities:
1. Ayane's epilogue is the end of the reset, and the rest of the main events are the "new" reality after they come back (which I'm thinking will be quite different from usual). In this case the reset ends by the middle of the update.
2. Ayane's epilogue is about Akira, Ayane and Hima-chan, and then the rest of the events are either about the others caught in the reset, or about Hima-chan's journey interfering with everything in a huge flashback from her perspective (since she herself can't have character events). In this case the reset ends with the end of the update.
Regardless, I think it's likely that all of Ayane's events happen first, yes.
