Inspired by Heart of the Cards.

Everything was almost peaceful within the magical land of Equestria, key word: almost. Two days before the Summer Sun Celebration, a bunch of strange cards started appearing out of nowhere all over Equestria, and some of them started making ponies go crazy, it warranted enough attention for the princess to get to the bottom of this. Princess Celestia, ruler of all of Equestria, decided to conduct her own investigation on these cards, after casting a unique spell, she accidently pulled a human named Yulo Shinsetsu from his home world called Earth and told her about the card game from the strange cards, Duel Monsters.

She immediately enlists his help in stopping these incidents and protecting her subjects from any further harm, he is hesitant at first, but agrees after Celestia promises to find a way to send him back.

But little do they know is that those cards are the least of their problems, especially when threats from Equestria's past come out of the woodwork...

Author's Notes:
This fanfiction will introduce a new Duel Disk design I came up with and are planning to build.

This story is not canon to Heart of the Cards, this is merely a bout of inspiration come to life.

A personal note to AspirantWriter, the author of Heart of the Cards, if you believe that I'm ripping off your story by writing this, please PM me with your concerns, and we'll try and work something out that'll separate our two stories from each other and prevent copyright issues.

When cards of unknown origin begun to appear across Equestria, incidents begun to arise related to their appearance. While most are harmless, a few of the cards ended up corrupting the personality of those who touched them, attempts to stop them proved to be fruitless as the corrupted ponies kept on saying they could only be stopped in a duel.

Princess Celestia, the ruler of Equestria, casted a spell on one of the cards in hopes looking into their purpose and find a solution in the process. The spell backfired and she ended up warping a scared pony with a backpack in front of her. Much to her surprise, the pony claims himself to be a being known as a human named Dusk from a world known as Earth.

Celestia was more surprised when Dusk showed her the contents of his backpack; containing a unknown object and multiple deck of cards with the back design being the same as the ones that appeared in Equestria. He explained that he plays a popular card game known as Duel Monsters and he was packing his Duel Disk and his cards for a tournament prior to being warped.

Celestia realize she may have unexpectedly brought forth the solution she was seeking...

A lone vampire bat sneaks through the mirror portal and ends up in the human world. Instead of apples, it now craves something far richer. And unfortunately for Sunset Shimmer, she's its next snack.

Sunset can't remember any of her activities past sundown. The light hurts not just her eyes, but burns her skin. And she's thirsty.

So very thirsty.

It's up to the Rainbooms to save Sunset from herself before she drinks the whole city dry. Too bad Twilight Sparkle is her primary target.

Now with a TVTropes page!

Now with a French translation!

Sora was an average teenage boy, though average was an understatement. At the age of fourteen, he was thrust into a battle between light and darkness, wielding a mystical weapon known as the Keyblade, saving worlds from creatures known as the Heartless and finding his friends, Riku and Kairi. He has saved the universe many times from the Heartless, saved Kingdom Hearts from being controlled by those with evil intentions, and has made new friends in each world he visited.

However, he fails his mark of mastery exam after almost getting himself killed by Xehanort's younger self, needing to be rescued by his friends as Riku and Kairi become Keyblade Masters. Needing more training before he can retake his exam, Master Yen Sid gives him coordinates to somewhere in the galaxy, though the information on what was there or why was unanswered, obeying his teacher. But as he was close to reaching the coordinates, his own gummi ship, which he crafted on his own while on a break a week prior to his exam's failure, malfunctions for some unknown reason and crashes into the world of Equestria.

With no way to make it back home, and Equestria too far from the rest of the worlds to contact his friends or fix his ship, Sora is stranded on this new world until someone realized he's been missing. Until then, he's going to have to fit in, his magic transforming his body into being a part of the world like in many others he visited in the past, and be patient. Little does he know that there were also dangers that lurked in this world, aside from any Heartless that may appear.

Sora's story takes place after the events of Dream Drop Distance, his adventures beginning in Equestria before the season 1 premiere of My Little Pony: Friendship is Magic.

Kingdom Hearts is owned by Square Enix and Disney. My Little Pony: Friendship is Magic is owned by Hasbro.

EDIT: Those who are new to this story, there are links in a majority of the chapters where they lead to soundtracks of Kingdom Hearts to help build an atmosphere in the story. Sadly, most of them may come up as dead links because those videos had been taken down by the YouTuber for some reason, even if there are some still active by that same person, or they'll be gone as well if they happen again. With how many chapters I've put in this story, and how many links there might be, I don't have the patience to take them down or find new links with the right music I chose for those moments if I can remember which ones. So, up until Equestria Girls: Legend of Everfree (Part 3), ignore the links, as much as I hate to say that with the hard work I've done. Hopefully this crossover will be as enjoyable without music as it keeps on going.
