History Heartwarming / PrincessTutu

* Princess Tutu can never confess her love for the prince, or she'll disappear in a flash of light. However, when faced with losing him to Princess Kraehe and leaving him heartless forever, she does it anyway...[[LoopholeAbuse through dance]].
* When Ahiru went to such great lengths to protect Pique from becoming a sacrifice for the Raven early in the second season, showing that she truly does value her as a friend and not just a roommate, or one of [[ThoseTwoGuys Those Two Girls]].

* Early in the series, the first time that Fakir shows some kindness to somebody other than Mytho: when he rescues Duck Ahiru from his locker and gives her bread. Also a SugarWiki/{{Funny Moment|s}}, because Ahiru almost loves him for his bread.

** Also in Akt 23, Uzura meets the puppet she was made from, Edel, and asks her if that means Uzura isn't real. Edel replies that she was just a puppet, but Uzura is different...and Uzura begins to cry.

* In the last episode, Rue meeting up with Ahiru, who's now permanently a small yellow duck, asking her if she's the Ahiru she knows. The duck nods, and Rue cries and hugs her, thinking of Ahiru and saying she loves her. Ahiru hugging Rue back with her wings and her thoughts of "I love you too, Rue." is the icing on the cake. Awwwww, too!

* After Mytho has his heart back, Ahiru turns back into a duck. Every time he refers to, or speaks to her, he still calls her Princess Tutu. Because as far as he's concerned, she's still a princess at heart.

* Akt 10: Fakir's adoptive father decides to believe in his son after meeting Princess Tutu and allows him to fight to protect Mytho. He sends him off with an embrace; "Go, my son."

* The sheer lack of hesitation with which Rue admits [[AnguishedDeclarationofLove her love]] for Mytho and offers her own heart up in his place, and the fact that it's her confession that frees Mytho and brings him back to himself and not Tutu's is an incredible subversion of the genre that I'm sure a lot of viewers weren't expecting.

-->'''Mytho:'''"The story says I'm supposed to love everyone... but right now... I simply want to love Rue the most out of anyone." Cue Rue crying happily and him hugging her. Awwwww!

-->'''Mytho:''' ...That something so small and fragile accomplished this...Thank you, Princess Tutu.

* ''Princess Tutu'' has as many of these as it does correspondingly dark moments, but one of the best comes in Akt 23, when [[spoiler:Tutu is kidnapped by Drosselmeyer and the story stops. Then, because of Uzura's meddling, it starts going backwards. Fakir, realizing how much Ahiru has changed him, refuses to go back to who he used to be, and begins to write Tutu's story down for her, pulling the story flow back on course and freeing Tutu from Drosselmeyer's clutches.]]
** Pay special attention to that, while she's in Tutu guise for the entire episode, [[spoiler: the name Fakir cries out to save her is ''Duck''.]]
** Also in Akt 23, Uzura meets the puppet [[spoiler:she was made from, Edel, and asks her if that means Uzura isn't real. Edel replies that she was just a puppet, but Uzura is different...and Uzura begins to cry.]]
* In Akt 22, Kraehe is attempting to seduce a new victim for the raven and her target is [[spoiler:Autor. As she's taking him to be sacrificed, however, he confesses his genuine love for her - Kraehe has been told over and over again that only her father and the prince will ever love her - and Kraehe can't bring herself to kill him.]]

* Princess Tutu can never confess her love for the prince, or she'll disappear in a flash of light. However, when faced with losing him to Princess Kraehe and leaving him heartless forever, she does it anyway...[[spoiler:[[LoopholeAbuse through dance]].]]
* When Ahiru went to such great lengths to protect Pique [[spoiler: from becoming a sacrifice for the Raven]] early in the second season, showing that she truly does value her as a friend and not just a roommate, or one of [[ThoseTwoGuys Those Two Girls]].

--> [[spoiler: '''Fakir:''' "And even after that time comes, I will stay by your side forever."]] D'awwwwww!
** Realizing [[spoiler: that it was the first time Ahiru danced gracefully as a girl and not Princess Tutu]].
** Ahiru musing [[spoiler: during her dance with Fakir]] that somehow, he makes her feel strong.
* At the end of the last episode when [[spoiler:Mytho asks Rue to come with him to his kingdom and be his princess. When Rue points out that she has the monster Raven's blood inside her he says this.]]
-->'''Mytho''': [[spoiler:"The story says I'm supposed to love everyone... but right now... I simply want to love Rue the most out of anyone."]] Cue Rue crying happily and him hugging her. Awwwww!

* After Mytho has his heart back, [[spoiler:Ahiru turns back into a duck]]. Every time he refers to, or speaks to her, he still calls her Princess Tutu. Because as far as he's concerned, she's still a princess at heart.

* In the last episode, Rue [[spoiler: meeting up with Ahiru, who's now permanently a small yellow duck, asking her if she's the Ahiru she knows. The duck nods, and Rue cries and hugs her, thinking of Ahiru and saying she loves her. Ahiru hugging Rue back with her wings and her thoughts of "I love you too, Rue." is the icing on the cake.]] Awwwww, too!
* Fakir [[spoiler: promising to never leave Ahiru's side even after she loses the ability to be human]], after her worrying for the entire series that people would reject her if they knew she's really a duck.
** Also, the last scene in the series [[spoiler: is Fakir sitting on a dock near a lake, with Ahiru-as-a-duck floating in the water]], showing that Fakir very much intends on staying true to that promise.

* Though the epilogue is bittersweet, with [[spoiler:the town returning to normal and no one remembering Ahiru, the scene near the end with Mytho and Rue dancing happily together is ''very'' sweet. Rue is not a character archetype that often gets a happy ending. This girl has been used and abused and manipulated her entire life, and had to overcome a lifetime of suffering and being beaten down to set right her wrongs. To see her finally get the one thing she always wanted - someone to love her - is an immensely satisfying conclusion to her character.]]

* Ahiru rushing in to save Fakir from the Bookmen has to be one of ''the'' greatest heartwarming moments of the series as a whole. [[CrowningMomentOfAwesome The choice of music for the scene certainly doesn't hurt either.]]

* Early in the series, the first time that Fakir shows some kindness to somebody other than Mytho: when he rescues Duck Ahiru from his locker and gives her bread. Also a CrowningMomentOfFunny, because Ahiru almost loves him for his bread.
