The future of dueling is revving up! And with it begins a new legend! Yu-Gi-Oh! 5D's!

Welcome to New Domino City! Once the playground to legendary duelist Yugi Muto, this sprawling metropolis has since been transformed into a futuristic society where dueling has kicked into overdrive. With recent technological advancements made by KaibaCorp, dueling has undergone a metamorphosis that has revolutionized the makeup and pace of the game! It’s now a heart-pounding, adrenaline-filled and fuel injected competition where duelists ride supercharged hyper cycles called Duel Runners and battle it out in hi-octane contests called “Turbo Duels.” The winners and losers aren’t just separated by skill and strength… but by SPEED!

However, for five special duelists, it's not just about winning or losing anymore - it's about survival, for they are the chosen "Signers" who have been marked by destiny to uncover the secrets of the five dragons!

Thanks to Sharuru, a fairy from the Trump Kingdom, and the power of mysterious accessories called Cure Lovies, Mana transforms into Cure Heart! Mana, her close friend Rikka, her high-class childhood friend Alice, and the enigmatic, cool super idol singer Makoto all become legendary saviors. Together, they purify the Jikochu, who have forgotten about love!

Here come the Crown Knights: Sunday Spades — the poker-faced leader and possessor of the mysterious trump power! Jo Diamonds — who can run at the speed of light! Casa Clubs — combat expert who possesses hyper-senses! Coco Hearts — the tricky master of psycho-magic!

Together, these cute, card-carrying champions are dealing a world of hurt to the criminals who threaten the tranquil Card Kingdom. But can they checkmate two, invading war machines — shaped like gigantic chess pieces — before the kingdom topples like a house of cards?
