Yuko was a normal teenager in the real world. But tragic happened when he was walking home, and he was hit by truck because of a drunken driver. He was then reborn into his favorite anime show, Yu-Gi-Oh! 5Ds! But he was reborn as Prince Kanata from Pretty Cure Princess. He found himself to be living in a world where Duel Monsters are alive, and he is the prince. He even made friends with Earthbound Immortals and Duel Monster Dragons. The Earthbound Immortals, Dragons and other Duel Monsters were very protective of him. But tragic occurred when darkness took over some of the Earthbound Immortals and the Crimson Dragon and its followers were in a battle against them. They won but it came with a price as the defeated Earthbound Immortals took the Ancient Fairy Dragon with them. Yuko or Prince Kanata was devastated about that and decided to travel to the human world and find them and save them from the darkness. He even meets Yusei and his allies and saw that they have the signs from the Crimson Dragon itself. Together, they will go on adventure to save the world from the darkness.
