Some years have passed since the dimensional war ended, through those events were still livid in our Lancers' mind they all manage to go on with their lifes.
In the XYZ Dimension Heartland City was totally rebuilt thanks to years of combined hard work. Dennis even opened his own Dueltaining School keeping in mind Yusho's teachings, but adding even his personal touch.
Yuto and Lulu had become a couple, they already had feelings for each other but they still had to make it official, and even if Shay at the beginning wasn't fond of it as a protective older brother, he slowly accepted Yuto in his family, he was a great friend to begin with and that helped a lot, together with Kite they could all have fun together like when they were kids.
In the Synchro Dimension the division between Common and Superiors was non existent anymore, both classes worked together towards the progress and after the kind of dictatorial regime that Roget was planning for the city, nearly destroyed it, they decided that a Parliament would take decisions for New Domino City, and only with mutual consent they would act on anything.
Yugo had finally managed to get Rin to become his girlfriend, after lots of tries she finally surrendered to his charm, or so he said.
A new edition of the Friendship cup was coming soon and they will finally live their dream, hoping for a chance to duel against the King Jack Atlas.
In the Fusion Dimensions Duel Academy had become the perfect Dueling School, Leo had implemented teachings for every summoning methods, even Pendulum. At that point everyone had forgiven Leo for his mistakes, but he still had troubles in forgiving himself, so he continued his researches diligently, to know everything in order to avoid something like that ever again.
Yuri had on his mind only dueling strong opponents and would usually travel between dimensions to calm his thirst for a challenge, deep down he changed his evil ways, but would still flash his arrogant smirk from time to time.
Sora would spend most of his time in the Standard Dimension, curious how he is now in a relationship with that same girl he tutored on fusion summoning years ago, Zuzu was really happy as well.
And last but not for importance we have the Standard Dimension, Yuya and Celina are now both 18 years old.
They quickly climbed the rankings in the Pro League, reaching the same level as Declan, agencies from all over the would would offer anything to have them in their personal Team.
Their carreers let them earn a really good sum of money, and recently they had rented their own apartment, they now had it only for themeselves, even if this didn't stop the respective parents to cry in happiness because their children were now adults, making them pretty embarassed.
They even got their driving licenses following that as a gift from the Synchro Dimension they got to keep the same Duel Runners they used in the Friendship Cup as their own completely free, much appeciated from the both of them, the runners were helpful in moving through town very quickly for any need or problem.
Obviusly the carreer wasn't the only thing going well for the two, their bond getting stronger every day, she couldn't be happier to be showered with love by her boyfriend, who first showed care for her as a person, and made her understand the values of bonds in life. Leaving aside any memory about her difficult childhood, basking in each other's warm touch was enough to heal any scar from their tormented destiny as reicarnation of Z-Arc and Ray.
They went in lots of dates together, shared many kisses and had fun in many different ways together.
They even dueled as tag duel partners when the circumstances allowed it, their fusion and pendulum combo was one of the strongest ever seen in the Pro League, showing that their compatibility was not only perfect in their relationship but between their decks too.
But they both knew there was a missing piece in the puzzle, something that could be done only when they were absolutely ready.
They have even talked about it in some occasions, but some reason or another none of them was able to make the first move on the the other, like if having a really bad starting hand in a duel.
She knew he didn't dare because of respect towards her and for her it was the same, but one day this stall war finally came to an end.
A Saturday evening Celina had just hopped off of her Runner, after parking beside hers and Yuya's apartment.
She removed her helmet, and used her keyes to open the door, Yuya was still out for a business meeting that day, so she decided to let him find dinner ready for when he would be back.
After a quick shower, she readied herself to cook dinner, she learnt to do that thanks to his sister and her father, at the time she didn't understand it but they said it would be extremely useful later on.
"They were right after all" Celina thought after she was done, spaghetti pasta with meatballs were a classic, never could go wrong with that, both her and Yuya found them delicious.
In that moment a rumble of keys could be heard, and Yuya made his way into their house, after closing the door behind him.
She was quick to stood up from her chair to meet him halfway from the table.
They hugged each other.
"Hi Celina, how are you?" He said while hugging her.
"Fine Yuya, but now that you are here I feel even better" She answered hugging him tighter.
"I'm glad to see you as well, sorry if I'm late" He caressed her head, basking in her sweet aroma.
"Don't worry, I've already made dinner for us" She said as they released from each other.
"You are the best! I should have a shower first though, see you in a bit!" He said as he rushed towards the bathroom.
"Take all the time you need" She said as her she smiled brightly, before taking a seat on her side of the table.
A quarter of hour later he was out with fresh clother and took his spot at the table in front of her and they started eating, while also talking about their day, they soon finished, Yuya decided he would wash the dishes since Celina made prepared their dinner to return the favor.
"I'll take care of these dishes real quick, go have a seat and relax" He said to her.
"Fine, but don't break anything" She said with a playful smirk knowing he could be clumsy sometimes.
"Come on, it only happened twice that I broke one" Yuya said with a blush.
Celina laughed at that, which had become a regularity between them, but he would everytime lose himself in seeing her being happy like that.
"She's so beautiful when she smiles, and she become prettier every day that pass" He tought as he worked on the dishes.
Yuya had sure noticed how their body had grown over the years, in particular Celina's, how her curves were more pronunced, adding that she attends weekly training sessions in a gym.
As reasoning she said that not only she wanted to become stronger as a duelist but also wanted to make her body physically stronger, and the exercise eased her nerves giving her a sense of calmness.
All that training had made her body even more attractive, charming lots of guys that had a glimps of her, but he knew that she wouldn't graze them of a look, she was only faithful to him.
When he was done with the dishes he went in the living room, Celina had on the couch patting the spot beside her for him and he soon joined her.
"What about watching a movie this evening?" She proposed to him with a DVD in her hand.
"I'm totally fine with that" He agreed as she then opened the custody to put the DVD into the player, before taking her spot on the couch again, Yuya leaned his back on the couch and Celina decided to lean on his shoulder, which he gladly accepted, her hair still had the shampoo scent, which still made him feel an awesome feeling of relaxiation.
It was a romantic movie and when it reached its climax it obviously reignited something inside of them, the passion that came from the declaration of mutual love, each giving the other longing gazes, it was clear as the sky they both wanted to experience that.
As the film ended it was time to confront each other about it.
"It was a nice film... don't you think?" Yuya started, not exactly managing to say what he wanted.
"Yeah, very entertaining..." Celina didn't fare much better.
But she knew she had to break the ice, so in one of her boldest moment she pounced on Yuya, straddling him and looking deeply into his eyes.
He secretely loved when she would take the lead, but was too shy to admit it.
"Yuya, you know that I really love you right?" Celina stared at him with a loving look.
"Sure, I love you too Celina" Yuya had the same exact look, nearly mesmerized by her.
"Well, I think I'm ready" She said not specifing the context but he soon connected the dots.
"You mean..." He started but she put a finger on his lips.
"Yeah, tell me, do you feel ready?" She asked with hopeful eyes.
"I mean, I would lie if I said I don't want to do that with you, but only if you are ok with it" Yuya said rubbing her back, always respectful.
Her eyes sparkled with newfound emotions, he felt attracted by her like never before, a smile was on her face, the same he gifted her years ago.
"I'm fine with it, I want the person that changed my life for the better to do it!" She said with a sultry look, her lips reaching for his for a kiss, she wanted it and he wanted it, they could feel their souls and their bodies calling for each other, it was almost like that every experience they shared were leading to this moment.
"Celina... uh..." Yuya knew there was no coming back after this, but his instincts were screaming at him to cooperate, leaving any logical thought aside, he could only hear one more thing before the temptation would consume him completely.
"Let's create the ultimate Polymerization together!" Celina announced before closing her eyes and uniting their lips together starting an heated make out session, which would soon transform into the maximum expression of love for each other, the two lovers engaged in a sacred dance that would make them soon unite as one, a full moon shined in the background of their home, its light highlighting the greatness of the moment.
It was the crowning of a dream, no more pain and suffering but only love and care for each other.
