Edit: I just went in to fix typos. That's all

So I'm going to tell you in advance that the kidnapper (for in the situations Yuya gets kidnapped)  is my OC named Ameri. This is her

She's German but she comes from the Synchro Dimension, even though she's in the XYZ Dimension a lot

Yuto

"Finally found it..." Yuto mumbled as he leaned against a wall to catch his breath. He was currently standing in front of a somewhat destroyed warehouse in the XYZ Dimension. Yuto would've never guessed that Yuya was inside if it wasn't for the Odd Eyes Pendulum Dragon card he found laying outside of it. Now that he's found it, Yuto can rest a lil bit, but not for long. Who knows what kind of troubles Yuya could be in.

When he finally caught his breath, Yuto send a message to Shun giving him his location before entering the warehouse, Yuya's ace card in hand. Inside the warehouse was debris everywhere, not giving an exactly clear path to the middle, but Yuto managed. When he arrived in the middle, Yuto saw two things: a girl and Yuya. Yuya was chained to a metal pole that seems to be bent down in a U position so there was no way to slide the chains off. He also didn't have a shirt but he still had his green cargo pants and his reddish orange shoes. As for the girl...

Blond, with red, white, and blue bangs. Blue eyes, wearing what seemed to be a... black lab coat? Orange ribbon tied to her arm. She wasn't saying anything but she was rubbing something against Yuya's bare arm. What freaked Yuto out was the fact Yuya wasn't even trying to fight. He watched but didn't squirm.

As the girl started pulling something out of her pocket was when Yuya said something. "What's that?"

"A syringe. It'll help the process," The girl replied. Thick German accent. Yuto decided that was enough info before leaping out of his hiding place and attacking the girl before she could give Yuya whatever was in that syringe. The fight between him and the girl was somewhat brutal but in the end, Yuto won. He got off the now unconscious girl and ran over to Yuya, who was staring in surprise.

"You fought a girl."

"Oh my goodness Yuya there are much more important things at the moment than that," Yuto responded as he broke the chains. "Where's your shirt?" Yuya shrugged as he got up before hugging Yuto, who was quick to hug back.

The police and Shun came by later, with good fortune for the girl was coming to right then. While the girl escaped, her colleges didn't. They were apart of a gang called the Flares. That girl happened to be the leader. Yuto later learned her name was Ameri.

But he didn't care. What Yuto cared about was the exhausted Yuya in his arms as Yuto gave him a bath at his house. It took a bit but eventually Yuya got himself ready for bed and plopped down next to Yuto. They both fell asleep, happy to have one another again.

Yugo

"AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA"

Yugo didn't know how's it happened but Yuya got himself underground. So what was Yugo doing at the moment? Driving, or rather falling, down a garbage shoot to the Underground.

"AAAAAAAAAAAAAAA-" he landed hard into a pile of garbage. Yugo quickly got up and looked around for his Duel Runner. Luck was on his side for it was perfectly okay. Yugo slid himself and the runner down the garbage pile and started his search. Wasn't long before he had to get on the Runner and ride away from Underground Security though.

Meanwhile, Yuya was in the morning group of Underground Castaways sorting from forks, spoons, and knives when he heard the all-too familiar sound of a Duel Runner in the distance. When he and everyone else looked up, they all saw Yugo screeching as he drove past them, followed by the Underground Security. They were very much slow compared to Yugo, who was driving around the place at 50mph. It took a bit but eventually Yuya realized that it was Yugo on the bike.

"Yugo!!!" Yuya yelled as he started jumping up and down while waving both his hands in the air in hopes of catching the Bluenana's attention. It wasn't long before he did. Yugo pulled up right next to Yuya.

"GET ON!!" Yugo yelled as he tossed Yuya a helmet. Yuya put the helmet on while getting himself secured onto the Duel Runner. Once he was on and hugging Yugo, Yugo took off again. It didn't take long for them to reach the surface, even with Underground Security trying to close them in. Yugo stopped and hugged the tomato-haired boy once they were back at Yugo's house. Yuya was quick to hug back. They didn't care about the stares they got, they were together and happy.

Yuri

64...

Yuri has carded 64 people and it was about to become 65. He stood currently face-to-face with Yuya's kidnapper. How'd he know this girl was the one who kidnapped Yuya?

"YURI STOP IT WITH THIS UNNECESSARY VIOLENCE!! THIS IS EXACTLY WHY XYZ DONT LIKE FUSION!!" Because Yuya sat chained some distance behind her.

Yuri ignored Yuya's comment. "I'll ask nicely one last time: hand Yuya over."

"So you could card me? No thanks!" The german accented girl scoffed at Yuri. That was Yuri's last straw.

"Duel me then," Yuri started up his duel disk.

The blond laughed. "Sorry but I don't duel! Especially not with Duel Academy's top dog!"

"Then hand. Yuya. Over."

"For one thing," The girl purred. "Give me a Academy's duel disk then I'll let your hubby go."

"I thought you didn't duel."

"Doesn't mean I can't teleport."

"Fine," Yuri spat venom as he took out a spare duel disk and tossed it to the girl. She caught it. "Now give me Yuya."

The girl giggled. "Fine. Here," a key was tossed to Yuri, who caught it and quickly ran over to Yuya. Yuri quickly unlocked the chains and freed Yuya, then turned around to attempt to card the girl for kidnapping Yuya but she was gone. Yuri snarled before turning back to Yuya. 

"You okay?"

"I'll be fine but whY DID YOU CARD 64 PEOPLE?!?!?" Yuya yelled midway through his question.

"I got mad okay?!" Yuri pouted.

Afterwards, Yuya refuses to talk to Yuri for a week before accepting his apology.

Sora

As expected, Sora lost Yuya and his kidnapper, but that didn't mean he couldn't find them. And he did. They were in XYZ Dimension, one which Sora hated for it reminded him of Shun. Cliche moment: they were in an abandoned warehouse. Sora kicked open the door just in time to see the kidnapper put Yuya down. As soon as the door was opened, the person whipped around to face Sora, but too fast for their hood fell off revealing blond hair with red, white, and blue bangs and blue eyes. It was a female.

"I didn't know girls were this desperate for boys nowadays!" Sora decided to taunt.

The girl scoffed before pulling out a knife and putting said knife next to Yuya's neck. "I don't want him." Sora decided that he shouldn't taunt or tease the girl anymore.

"Well, can we duel for him at least?" Sora attempted to negotiate.

"I don't Duel," her german accent was thick. She was definitely German, Sora decided.

"Uh... then can I have him back for free.....?" Sora used a puppy-dog face.

"No," The girl didn't even bat an eye at Sora. "But you could offer me Yuri."

And that was how Sora got Yuya and Yuri was traded off against his will. Yuya was mad at this and eventually made a trade for Yuri. He got Yuri while the girl gets a crate of tomatoes and an Italian girl who kept claiming to be said crate of tomatoes. Everyone was sort of happy after that.

Shingo

"What do you mean you don't duel?! HOW DID YUYA LOSE TO YOU IF YOU DONT DUEL?!?!?" Shingo was yelling at a German lady who was holding Yuya in chains. Quite literally. As in Yuya had handcuffs and a collar and attached to that collar was a chain and the girl was holding the chain.

"He lost to one of my men," The girl gestures to a man in a suit who was to her left (Yuya is  sitting down to her right) "He gave your 'Yuya' to me so now I own Yuya."

"SLAVERY IS ILLEGAL THOUGH!!" Shingo protested.

"Zend Destroyer the Third isn't a slave." The girl snapped back at Shingo.

"WHOSE ZEND?!"

"Yuya. I gave him a new name."

"WHAT KIND OF NAME IS ZEND DESTROYER THE THIRD?!?"

They kept bickering like this for a bit before Shingo ended it. "WELL I GAVE THE MILI-" 

The military broke down the door and charged in, leaving Shingo yelling "LET ME FINISH MY THREATS PLEASE!!!". In the end, the girl, whose named was revealed as Ameri later on,  managed to escape but everyone else was arrested and Yuya was freed, now hugging Shingo.

"So Yuya-"

"Shingo that isn't my name," Yuya pouted. "It's Zend Destroyer the Third!"

"YUYA DONT YOU DARE JOKE ABOUT THAT!!" Shingo's response left Yuya crying from laughter.

Yuzu who again same situation as Shingo just no Shingo and no military

Yuzu was currently staring at the girl, who was sort of amused to see Yuzu actin the way she is.

"So let me get this straight. I free Zend Destroyer the Third-"

"Yuya," Yuzu interrupted.

"... Zend Destroyer the Third. You won't tell anyone of us AND you'll give me Yuri?" The german girl asked.

"That's right! I even have Yuri here," Yuzu gestured to the caged Yuri, who was protesting.

"Deal. Here's your Zend Destroyer the Third," The girl threw the chain down, which gave Yuya the ability to run up to Yuzu and kind of hug her. Yuzu lead Yuya our before he could remember that Yuri was his trade-off. 

With the help of her father, Yuya was freed from the chains and the collar. A day later, Yuya went back and managed to get Yuri, who was dubbed Zend Destroyer the Fourth by the girl who had said her name was Ameri.

Reiji

"Ameri Zendaya, age 14. She's from the Synchro Dimension but she's currently in the Fusion Dimension. What should we do sir?" The worker turned around and faced Reiji.

"Nothing. Moonshadow should be able to do this, I presume?" Reiji turned towards the ninja, who nodded before disappearing. They didn't appear until a day later, which had given Reiji the time he needed to finally sleep and eat for he had been working on coffee only in his search to find Yuya. Moonshadow reported that Ameri had managed to escape but he had Yuya, who was more than happy to be free.

"She called me a Zend Destroyer the Third! WHAT KIND OF NAME IS THAT?!" Yuya was telling Reiji about his little adventure while Reiji was hugging him more to calm himself down than to calm Yuya down. Once he had calmed down, Reiji adjusted his glasses and pulled somewhat away from Yuya.

"It's a terrible name."

"Thank goodness I'm not the only one who thought that!" Yuya laughed.

Mob Boss Yuto

Yuri was right: Sora was in the mountains, but he didn't have Yuya. Sora was furious when he learned that Yuya was missing, much to Yuto's surprise, for they were apparently friends from school. So now it was Sora and Yuto finding Yuya.

Yuri then suggested that they tried the beach, which they did. And there's they found Yuya and his kidnappers. The leader was a blond girl with blue, red, and white bangs and blue eyes. 

"Give Yuya back!" Sora was the first to speak up.

"You'll have to fight for the boy if you want him!" Her accent was very much german.

A fight did break out. Many dead, many more wounded, one of the wounded being Yuto but he only got shot in his hand, but Yuya was back in Yuto's arms unharmed. The girl managed to get away and, after a bit of threatening to one of her wounded mens, Yuto and Sora learned that her name was Ameri and that's they were the Flares. Through this kidnapping did Sora and Yuto make alliances though, which made Yuya very happy.
