question for all you theorist out there, would it be possible that at the end of all the resets the mayas that ended up going away, be part of the original? like little fragments, that are just trying to come together as one?
Considering "removed" memories tend to resurface through dreams for Makoto, Tsuneyo, and seemingly Sensei at least, it's likely possible.
Tsuneyo is definitely more of an oddity, but she at least seemed to recall hearing about the resets before hearing about them in this timeline:
And recalled being there to hear Sensei say something she wasn't there for, in this timeline:
Tsuneyo seemed to be recalling memories from past Tsuneyos through dreams that current Tsuneyo has, and it seems to be something she was unaware she was doing:
Overall: Based off Sensei having to mention the ferris wheel and talk to Tsuneyo about it before she started recalling things, Sensei probably needs to take New Maya to the festival on her bday, carry boxes with/for her, or maybe have a picnic on the roof. Then Maya Prime memories may start being recalled by New Maya.
Or it could imply that Maya Prime truly is gone. Only time will tell.
It also seems like a painful process, which would probably cause most to fight against remembering things even if they could. Which makes me recall what Maya once said:
When it comes to Maya Prime at least, she may have had Millions of years worth of memory (and suffering), so I'm not sure what would happen if it all came back immediately, or how long it'd take for a Maya to be a "Maya Prime" considering just how much more memories that version would have had, and what would be required to recall them.
Edit: If you simply meant whether or not there might be a Maya being used as a core for the creation of all the Mayas in the resets, then I'm not sure. The actual girls
could be elsewhere acting more as templates for the girls that share their shapes, hence the recent Template9 stuff in regards to Nao-chan. There also was how it seemed implied New Maya was a "Prototype":
Unless the melon was for someone/thing else.
