I think they mean Izanami's Act 2 ending. Possibly.

It sounds plausible. I wouldn't mind if that was the case, really, because that is a solid theory.

Yeah, it is inside the Embryo. That seems...logical actually.Logical for this series, anyway.

Well...didn't Ragna, Jin and Saya come from a lab anyway? Saya could be a clone of the girl in the Master Unit. Hell, some already theorise that Ragna himself is a Prime Field Device (No. 5), so it would make some form of sense (probably).

Maybe Saya's the 'True Noel' inside Amaterasu. It's not far off from what we thought already as Noel apparently looks identical to Saya anyway.
