So tokkan your saying that Noel is the master unit's core and she had been using prime fields as her vessels? Because I not to be rude or anything that is exactly what it sounds like at this point.
So we can all assume for the first part of story mode is based on the first 3 acts, while in the middle part is focused on Es ,and the last part is the conclusion with all the shocking revelations,plot twists, and Ragna's origins finally explained.
Well the console version should be a series of plot twists on that
Such as
Ragna,Jin,and Saya's real origins
Terumi's true identity and Hazama's true goals
The Master unit's identity
How Es became the guardian to the gate
How Rachel was born and basically what is behind that gate.
So can you give a full summary in a nutshell? Like what was Ariels? what was the others had been doing? Also how can Jack fuse with Justice to turn her back into Aria?
At this point saya pretty much became an even worse sibling towards ragna then even Jin himself as while Jin pretty much wants to kill ragna it's more about protecting the world while saya after being possessed and warped by Izanami the master unit's driven wants to make everyone die. Granted ragna does a get a little upset but he isn't hesitate to stop his sister even if it hurting her. As you said even Naoto was against it but ragna knows what is at stake so yeah.
Now It seems Ragna seems to realize that even if Izanami is gone the Saya he knew is dead and Saya is already dying also Noel is more like Saya then Saya herself.
It seems ragna's goals always changes first getting revenge on terumi,then trying to save saya,and now protecting the master unit. Geez Ragna make up your mind already.
But wouldn't that mean mu is her vessel as well? Why the the origin use mu as a vessel when Noel separated from her I think it meant that mu is the vessel while Noel is the origin's soul.
I think the master Unit possessed Mu in the main time as Noel prior to CT and sealed her own memories.
But we know that Noel does not have the prime field just the toucher appanetly so we don't know now that Noel is using the prime field's soul at this point.
