I don't what would be the point of bringing Zera back at this point. And Zera's mother can't be relevant at all because technically Zera died in the first chapter of Zero and the one that follows Mavis around is just an illusion. The original is completely irrelevant.

So unless Hiro finds a good and convincing way to explain why Zera is standing there without Mavis' magic, which she said that wouldn't work even if mavis wanted to, then I don't think I'll like it. That's why I'd rather this one be something else taking Zera's form than being her. To be fair, if fairies do exist in this universe it would be a good moment to introduce them IMO.
