A writer passed away before his work was completed, leaving behind the prince (voiced by Naoki Yasanagi) who had no ending in his work to wander alone. The prince and the crow, the enemy in the story, came to the real world. In order to protect the creatures in the real world, the prince sealed the evil crow with his heart. The ghost of the writer was unwilling to see his story stagnate, so he gave a duck a magical necklace, and the duck turned into Yaxier (voiced by Nanae Kato). Her mission was to find the fragments of the prince's heart that were scattered everywhere because of the seal of the crow. By chance, Fazia (voiced by Takahiro Sakurai) picked up the prince's heart and named it Miao. Fazia, who was afraid that Yaxier would take Miao Shi away, forbade the two to meet, but Miao Shi was curious about Yaxier instead.
