Long, long ago a man died whose job it was to make up stories to tell. But a man cannot violate the laws of death, and in his last tale, a brave and beautiful prince is out to repel the cunning Great Raven. Yet their battle had never come to fruition. "I don't want this!" The Great Raven cawed. "I don't want this!" The prince cried out in the same way. The Great Crow escaped from the story ...... Yachel was a lively and somewhat confused girl, and in her dreams, she would always see a beautiful and melancholy prince dancing a ballet in solitude. And she herself is an ugly duckling who only dares to hide in the distance and peep. In reality, Yachel is also the ugly duckling at school, with two very close sisters who have a crush on the school's ballet prince, Mutt. Mutt is the prince without a heart. Under the guidance of a storyteller, Yachel grows up to become Princess Hagi, who helps Mutt to find his divided and scattered heart. But what is Yachel to do when Princess Hagi is a character burdened with the tragic fate of not being able to unite with her prince? A long, long time ago, a writer died, and before he died, he wrote a story about a prince fighting a great raven. However, the story lost its ending due to the writer's death, and in pursuit of that ending, the story became reality and came to the town of Golden Crown, where the prince sealed the Great Crow with his heart in order to protect the people of Golden Crown, and from then on Golden Crown became a world where story and reality intersected, and where reality was manipulated by the story.
The writer, who became a ghost after his death, in order to keep the stagnant story moving forward to fulfill the originally scheduled tragic ending, gave a necklace to a duck that wanted to see the prince's smile, and this necklace allowed the duck to transform into a human girl, Yachel, and also allowed her to transform into the legendary Princess Hagi in the story, to bring back the prince's lost Piece of Heart back. However, Hagi is unable to confess her love to the prince without disappearing as a point of light.
Fakia, who picked up the prince who lost his heart, gave the prince his name - Mytho. Due to an accident, Fakia decides to isolate the prince from everyone in order to prevent him from suffering any further harm, even though he is Princess Hagi.
But as the pieces of the prince's heart return one by one, Mytho stops paying attention to Fakia and his girlfriend, Ruyu, and becomes curious about Hagi's existence. Lulu is frightened by Mutt's constant changes, and gradually remembers that she is actually the daughter of the prince's enemy, the raven princess Kure, a self-hypnotized illusion created by Lulu to prevent him from discovering that she is a raven. Fakia is afraid that once all of Mutt's heart is recovered, the tragedy in the story will happen again, and Mutt, who may have been a knight reincarnated in his past life, will not only be killed by the crows, but Mutt will also fall into the fate of not being able to defeat the crows and have his heart stabbed to death again, so she intends to break Mutt's heart back to the original point again, but Mutt said that he wanted to get his heart back, so Fakia no longer stops the Hagi Princess from doing so.
While Hagi was in the process of finding the Heart of Love, Kure appeared out of nowhere and kidnapped the Heart of Love and Mutt. In order to fight Kure, Fakia was injured, and they were guided by Edelweiss to the underground stage that Tolomasia had prepared for them. Kure threatened Hagi to confess to Mutt in person or else she would not give up the Heart Piece and Mutt. But Fakia stops Hagi, and he fights the raven summoned by Kurei, but he is injured even more and sinks to the bottom of the lake after cutting off the prince's sword before dying. Because of Fakia's determination, Hagi decides not to disappear but to live to save Mutsu, so she turns her thoughts into a dance and competes with Kurenai, and although Kurenai keeps reminding her that she's only able to dance perfectly by the power of her magic, the single-person duet she dances awakens Mutsu, who has closed off his heart, and Kurenai is unable to comprehend why she can't pass on her adoration to the prince, and retires sadly.
After leaving the underground stage, Edelweiss sets herself on fire to save Fakia and guide Hagi and Mutt, and while Hagi is saddened, Edelweiss asks for one last chance to see the Prince and Princess dance as a duo, and so under the light of the flames and the night sky, they dance duet after duet in the square.
However, the story doesn't end there ...... Fakia takes a leave of absence due to an injury, and after Mutt takes care of him and returns to school after a week's rest, Mutt tears up Mr. Cat's most cherished dancing shoes and sets Fakia up to make everyone think that he's been pushed from the second floor of the dormitory by him, and as a result, Fakia is suspended from school and punished for a week and moved out of the dormitory! Fakia is suspended for a week and moved out of the dormitory. Princess Kure tells Fakia that the reason why Mutt has become like this is because Hagi gave Mutt's heart of love to Mutt, which is stained with the blood of her father, the Great Crow. Soon the rest of Mutt's heart will be tainted by the blood of the Crow, and Mutt will go around and take young and beautiful hearts to offer to the Crow in order to bring the Great Crow back to life. Pico, a close friend of Yachel's, Freya and Hermina, who are also in the same ballet class, are almost tempted to give up their hearts because of Mutt's sweet words. When she fails to get her heart, Big Crow takes out his anger on Kure, and Mutt, who has been blackened by the raven's blood, keeps on saying that Kure is useless, which makes Kure doubt her father's words that "when the heart fragment is stained with the raven's blood, the prince will belong to her and will love her forever". After Mugatu extends his poisonous hand to his sister, Rachel, who has taken care of Fakia since he was a child, Fakia is unable to fight Mugatu even with his sword, and Fakia realizes that he cannot protect anyone with his sword. Fakia realizes that he can't protect anyone with his sword. So he has to face the power he's been afraid to face since he was a child - the power to turn stories into reality, a power that has caused the deaths of both of his parents, and so he's terrified of possessing it. But in order to protect the people he wants to protect (Mutt, Hagi/Yahiele), he decides to bring back the power he has sealed away, but it attracts the attention of the townspeople who are afraid of the power, and Fakia is taken by them to Tolomasia's tomb, where they intend to cut off his hand, as they did with Fakia's ancestor Tolomasia, to stop the new story from coming true. to stop the new story from coming true. But Hagi, who has just discovered that the remaining Heart Pieces are among the five gates, jumps out to stop the execution, and in doing so is taken by Tolomasia's gears to the Writer's World. In the Writer's World, Uzra, who fell in with Hagi, turns the gear that turns back the story, allowing Kure to see the past plot of the story, allowing her to discover that "she is not the daughter of a raven, but rather, she has human parents but was kidnapped by a raven as a child," indirectly allowing her to realize that everything the Great Crow had said in the past (that she is a raven who has descended to be a human, and that it is impossible for anyone other than the raven and the prince in the story to love her) was all for the sake of the love of someone else. She realizes that all of Big Crow's past claims (that he was born as a human crow, and that it was impossible for anyone but crows and the prince in the story to love him) were lies to keep her from realizing the real truth, and she breaks down when she sees the prince, who has been completely transformed into a crow due to the curse of crow blood. Meanwhile, in order to save Hagi from the grave, Fakia writes a story and calls out Yachel's name to save her from the grave. After seeing the prince who has turned into a raven, Lulu breaks down and asks Yachel not to return the remaining pieces that sealed the Great Raven to the prince because once the Great Raven is unsealed and all of the prince's heart returns, the prince will offer himself to the Great Raven. However, when Adelou within Uzra tells Yachel that the necklace that transformed her into Princess Hagi is a fragment of the prince's heart, she realizes that it is the prince's intention to get back all of his heart to fight the Great Crow, and she is willing to follow the prince's intention and convinces Lue to allow her to return the remaining fragments of the sealing raven to the prince, which might lift the raven's curse. However, after the raven lifts the seal, the prince's curse is still not lifted, and when the prince flies Hagi to the raven, Lue cries out that she is willing to sacrifice herself and asks the raven not to eat the prince's heart, and confesses her heartfelt feelings to the prince. This move lifts the prince's curse, and the prince realizes the love that Lulu has been suffering in her heart all these years, but it also allows the Big Crow to find a breakthrough point, and the Big Crow imprisons Lulu and turns all the townspeople in Golden Crown into crows. The prince, who wants to save Lulu, asks Hagi to return the last piece of her heart to him, but Hagi can't take the necklace down. Tolomasia tells her that it's because if she doesn't give the necklace to the prince, her impression in the prince's mind will always be that of the perfect Princess Hagi, instead of an insignificant duck, and she feels that she can't return the necklace to the prince so that he can go and save Lulu and the people of Golden Crown because of the selfishness of her heart. selfishness. At the same time, Tolomasia manipulates Fakia's hand to make him write down the tragic story of Yachel, and with her low self-esteem, Yachel is convinced by the story and decides to disappear and sink to the bottom of the lake. Fakia urgently picks up a letter opener and runs it through the palm of his own hand to stop the manipulation of Tolomasia and then goes to the edge of the lake where Yachel disappeared and guides her out of the confusion of her low self-esteem and vows that he will be by her side forever, and he succeeds in taking the necklace after relieving her of her confusion. Under the guidance of Fakia's story, Hagi returns the necklace to the prince, and the prince, who has recovered all his heart, begins to fight with the townspeople who have turned into crows, but because the crows were originally townspeople, they are even more unable to do so. In desperation, in order to protect the townspeople, the prince intends to seal the big crows once again, and once he seals the big crows, Lue Yu also dies, and when he defeats the crows over time, he will kill himself and go along with Lue Yu. But he was stopped by Yachel, who turned back into a duck. Yachel decided to dance on the ground to distract the crow townspeople, so that the prince could go and save Lulu first. Under Fakia's power to channel Yachel's hopeful light, the prince, under his own real name, Siegfried, rescued Lulu from despair, and together they defeated the Great Raven! . After destroying the Great Crow, Fakia destroys the automatic writing machine that Tolomasia had created in the town before her death, ending the tragic ending of The Prince and the Great Crow, and the Prince then asks Lulu to become his princess, and ultimately the Prince takes Lulu back to the story, and the town of Goldcrest is no longer manipulated by the story but is truly brought back to reality.
