Emma is an ordinary elementary school student in Domino City.
After an accident, she gets a deck that changes her life forever.
Yugi Muto: "I'll show you my ace! Come forth, Dark Magician!"
Emma: "I summon Blue Dragon Summoner."
Jaden Yuki: "Return from space, Elemental HERO Neos!"
Emma: "I summon Sangan."
Yusei Fudo: "Synchro Summon! Appear, Stardust Dragon!"
Emma: "I summon Gravekeeper's Spy."
Yuma Tsukumo: "I overlay two Level 4 monsters to Xyz Summon Number 39: Utopia!"
Emma: "I offer Left Arm of the Forbidden One as a Tribute to Special Summon The Legendary Exodia Incarnate."
Watching Utopia, sent to the Graveyard, look at all the senior monsters there, he wore a wounded expression.
Exodia the Forbidden One, with his head chopped off by the guillotine, wiped the sweat from his brow and smiled happily.
"Haha, dueling is so much fun."
[The protagonist is Emma, and her main deck is an Exodia deck.]
