Come on, the part about that long-haired girl being a beastkin was obvious from the start.
Or have you guys completely overlooked the cover featuring her (or Melina in her body)?
You can still see it on the credit page at the start of chapter 5 for example.
So this development could not have been more obvious.
The real question is why Nasha's soul still looked like a human after being separated from her body.
Her soul was completely separated so the ring should not have had any effect on her soul anymore.
As such her soul should have had her original beatkin appearance.
