Where did you get this info?

And even if that's the case it makes sense.

Spoiler for Calamity Trigger True End:

Nu fell into the cauldron alone after Noel saved Ragna from doing the same thing, so Nu probably is gone forever.

Since Nu can't come back, they just replace her with the next Saya clone. They all have the same properties anyway.
