Author's note.

Hello everyone. Welcome to another Yu-Gi-Oh! Crossover fanfiction. This time, it's between Smile Precure (Glitter Force) and Yu-Gi-Oh! 5D's. But, before I get things going. I would like to graciously thank Yugi234 for helping me with this story, even giving me the idea for Emily's ace Synchro monster; Glitter Force Lucky Dragon. So yeah, yugi234, if you're reading this, thank you soooo much for your help and inspiring me to write this. And for everybody else, if you want to see his art and his stories; here are links to his Wattpad and Deviantart pages.

So, without any further delay, let's start this tale. I do not own the rights to Yu-Gi-Oh! 5D's or Glitter Force. Also, this story starts right after the events of Yusei vs Akiza hospital battle. So Crow has 'disappeared and Yusei had his first battle with Kalin.

Chapter 1

The fifth signer is where?

Yusei and the others arrived at Rex Goodwin's office.

"You wanted to talk to us?" Asked Yusei.

"Indeed I did", said Rex. "We now have four out of five signers here".

"That brings us to a question we've all been asking" said Jack.

"Jack's right", said Yusei. "There is one thing that has been on our minds. Where is the fifth signer?".

"I guess it's time that you knew the truth about the fifth signer" said Rex.

"Let me guess", said Jack. "There is no fifth signer and there's only a limb in a jar with the final mark on it?".

"Don't be foolish, that would be completely unrealistic", said Rex. "No, I'm saying that the fifth signer isn't even in New Domino City or the Satellite". This made everyone gasp.

"Not in the city?", asked Yusei. "Then how was the Crimson Dragon summoned if she isn't in New Domino?".

"The signer had decided to come here briefly to witness the fortune cup", said Rex. "However, she returned home after it was finished".

"So you're saying that fifth signer could be anywhere in the world?!" Asked Akiza.

"So what?", asked Jack. "We just go country to country and state to state until we find him or her?".

"That won't be necessary", said Rex, he then placed a folder on his desk. "I suggest you read this". Yusei picked up the folder and opened it. It showed a girl that looked three years older than Luna and Leo, but she had dark pink hair.

"Who's that?" Asked Luna.

"I don't know, but she's cute" said Leo. Luna then whacked him on the back of his head.

"That girl looks way older than you" said Luna.

"So, who is she?" Asked Akiza looking over Yusei's shoulder.

"Her name is Emily Hoshizora", Answered Rex. "She's a resident of the town of Rainbow Hills".

"Rainbow Hills?" Asked Jack believing the name of the town she was native to.

"I've heard of that place", said Akiza. "It's called that because after it rains, a large rainbow appears over the hills".

"So why are you showing us this" asked Yusei.

"Have a look at the picture behind her profile one" said Rex. Everyone gathered around Yusei as he lifted up the photo and revealed something that caused them to gasp. On the picture was a drawing of a dragon's head.

"That's a signer marking" said Yusei, still in shock.

"Right", said Rex. "Now you can understand why I showed you her file".

"So what now?" Asked Luna.

"You five are to head to Rainbow Hills, have Emily join you, return here and fight the Dark Signers" said Rex.

"And what are we supposed to tell her?", asked Jack. "Oh, hi Emily, it's me, Jack Atlas. Want to come with me and my friends to save the world from total destruction?".

"We'll cross that bridge when we come to it" said Yusei.

"So, when do we leave?" Asked Jack.

"You leave now", said Rex. "Go, find Emily and bring her here. Our world depends on it".

Rainbow hills.

At a house that looked like a regular home, there is a 14-yr-old girl resting in her bed. She woke up and scratched the back of her head. As she groaned from waking up, she looked at the mark on her right arm.

"Time for school" she groaned.
