I've been listening to the soundtrack and I think I might have discovered something.
When the latest update released there was all that talk about Himawari taking the scarf from Ayane, delivering it to Maya back in chapter one, making her remember, all these plots relating to one another and coming together creating a solid theory.
In the song secondmall.mp3, which plays during Amy happy event added dozen updates ago that takes place in a mall, the advertisement around 0:46 literally says:
"Himawari-co is pleased to present its brand-new product this weekend in the east wing. Regain your memories with little more than a flash. All it takes to move forward is a visit to the nearest kiosk. Returns and exchanges are unavailable."
A nice detail and needless to say, it is pretty much a confirmation, and from 0.32 at that. The nature of the event itself makes it a lot more interesting.
Also, the hidden Alexis event that was added in 0.45 takes place during that very event. You know, another thing on the account of the whole time travel business, maybe an afterthought, maybe something else.
And sorry if anyone has already mentioned it, but I don't remember any such post and neither did I find any with search.
