الدفعة الثالثة في امتياز Yu-Gi-Oh! مسلسلات انمي.

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?

Ten thousand years ago, a massive battle royale known as the Battle Fight was fought by fifty-two Undead, each representing a species fighting for dominance over all others. The winner was the Human Undead, known as Category Two of Hearts, giving dominion of the Earth to humanity. In the present day, archaeologists discover the sealed Undead, and accidentally set them free. Thus, a new Battle Fight begins.
