Summary: When the story ends, almost everyone in Goldcrown Town forgets that their lives had once been turned upside down by a story, that there had ever been a girl named Duck at all. But when Duck herself begins to forget, Fakir finds himself forced to write a story that costs him dearly.A fantastic could be canon fic by LunaSphere that's a sequel to the series, and an absolutely brilliant one at that, with all the characters trying to navigate what a happy ending means.Can be read here on fanfiction.net, and here with illustrations.Warning! Unmarked spoilers below for the end of Princess Tutu and for the fic!
Dark Is Not Evil: Having the raven's blood flowing through their veins doesn't make Rue or Mytho evil, nor do Rue's "darker" emotions, such as pettiness and jealousy make her evil, and in the end, when she dances as the Raven Princess once more, she does not call for the evilness of the ravens and crows from Drosselmeyer's story, instead she dances for the wildness of the raven, and accepts that it will always be a part of her.
She also has command of ravens in general. Including the baby ones Mytho kept bringing back to their room. Those aren't evil either.
Gilded Cage: The fairytale kingdom palace is this for Rue in the beginning, as this bit from chapter 7 demonstrates:
But really, [Rue] felt herself trapped in a cage as completely as she ever had when she thought the Monster Raven her father. [...] Now the cage was much more beautifulónot just gilded, but pure gold bars as fine as spidersilk, but bars nonetheless, festooned with chains of precious gems, a perch lined with seed pearls, a cage nonetheless. She loved Mythos. But human girls cannot live entirely in fairytales even if they have found their fairytale princes.
Hope Spot: Over and over. Yay, Duck's back, but Fakir's missing! Yay, Fakir's back, but something's wrong! Mytho and Rue are here to help, but Fakir is driving others to despair! Yay, we fixed him, but despair is turning all the townsfolk into stone! Yay, Duck can fix it, but she's really hurt and might die! After that it stars picking up for real.
Love Makes You Crazy/Love Makes You Evil: Fakir. When he realizes that Duck is forgetting her life as a girl (and him), he decides to give her a shard of his own heart to let her be human again. The part he gives her? His humanity.
Then it gets worse as he starts giving up the rest of himself until Duck shows up to give it back.
Nice Job Breaking It, Hero: While the Bookkeepers are really only heroes in their own minds, they really mess things up by trying to destroy the story Fakir had started. Then we find out Autor messed with the story before they did out of jealousy for Fakir's powers, also possibly messing things up.
Also, Mytho, showing up one second early to the climactic fight, thus necessitating a climactic fight since Duck didn't say what she wanted to yet.
Official Couple: Mytho/Rue, as in canon. And in the end, Fakir/Duck, as well.
Ravens and Crows: Well, given the source material... But their more "trickster" aspects are pointed out, and it's also given that they were not the bad guys in some of the older stories, that was Drosselmeyer's doing in "The Prince and the Raven".
Ret Gone: Twice over. There's the ret gone at the end of Princess Tutu that makes everyone forget about Duck, and then there's another one when Fakir gives his humanity to Duck, and no one remembers he ever existed. Not even Duck. At first...
Though he still has a few of his "didn't think that through enough" selfless moments.
Utopia: Mytho's homeland- or so it seems. In reality, it's a stagnant place where everything is perfect, but no one creates or moves forward thanks to there being no ravens there. In the end, the ravens return, and the land begins to move forward again, with art and sorrow and moving forward.
You Fool!: Fakir calls Ahiru this when she tries to restore his heart:
