As she was about to die, a light brought her back from the dead and transformed her into a swan and then human right before Fakir. While delighted to have her back, Fakir and Ahiru know that this sudden change must be an omen that there is something on the horizon. Not long after, the people in the town of Golden Crown start acting strange. It's almost like they were back in the Prince and the Raven story mixed with classic fairy tales. Fakir is able to write to combat it, with Ahiru taking on the crown as Princess Tutu again, but things keep getting worse.Then, a girl with a magical book that seems to read the past and read the future like an unfinished novel that seems to know everything about Ahiru and Fakir.

And with their service, she offers to return Ahiru to being human entirely once more.
