"Sky Magician attack Odd Eyes Pendulum Dragon." Yusho commands his monster. Yuya tries to reach for the action card but he barely misses. The attack continues and Yuya's ace monster is destroyed and his life points go to 0. The screens then flash Yusho's picture and name to declare him the winner.

It was just after Reira laughed as a sign that Zarc's soul had been purified and the return of Yuzu. Yuya Sakaki's father, Yusho Sakaki challenged him to a duel. Despite all of Yuya's growth as a duelist over his adventure to save Yuzu, stop the dimensional war, and stopping Zarc, Yuya still wound up losing to his father. Though he didn't care because it was an entertaining duel.

As Yuya lied down, Yuzu knelt down to talk to him. "Yuya, you did really great." Yuya says with a big smile.

"Thanks Yuzu. I mean I lost but my dad is really-" Yuya says but gets cut off by Yuzu. "No I didn't mean that. I mean everything you went through. You're amazing."

Seeing Yuzu's smile drew a big grin on Yuya's face. The two are then surrounded by their friends complimenting him on his duel. Things got a little distracting for them when Yoko started hugging and kissing Yusho. It wasn't surprising since she just remembered that her husband went missing for 3 years and all those feelings of missing him just came rushing back. Yuzu watched the open display of affection and started feeling a tug at her heart. "What are you thinking about?"

"Huh." Yuzu says from hearing a voice. She then noticed the transparent image of Serena next to her who was the one that just spoke to her. "You seemed to be in a trance by how those two are acting. Why is that?" Serena asks inside Yuzu's head.

"Isn't it obvious Serena? Yuzu wants to have what they have." Rin pops up followed by Ruri chiming in. "And I know whom she wants to have it with."

Yuzu just blushes at their teasing with Serena having an oblivious look on her face. Yuzu ignores her counterparts and turns to Yuya to talk to him. "Yuya. When everything calms down, I want to meet you in private."

Some time later, Yuzu is sitting on a couch in a waiting room Reiji provided so she could talk privately with Yuya. Yuya walked to the room muttering to himself what Yuzu could want to talk to him about. The conversation with himself soon drags in his own counterparts inside his mind.

"I wonder what Yuzu wants to meet me about?" Yuya ponders.

"Maybe another threat is happening and wants to tell us." Yuri brings up.

"Don't you think you're jumping the gun too much Yuri? Besides if there was a threat don't you think she would tell us the moment she came back." Yuto adds.

"Yeah besides what on earth could ever possibly a bigger threat than Zarc?" Yugo asks entering the conversation.

"I was only speculating given our own lives haven't gave us a moment of peace recently Fusion." Yuri explains followed by Yugo yelling, "It's Yugo!"

"Calm down you guys. I'm sure it's nothing." Yuya says before then saying out loud. "Oh, maybe she knows how to separate us."

"That's a possibility." Yuto says.

"Do you really think so?" Yugo states enthusiastically.

"I hope she does." Yuri adds.

Yuya opens the door to the waiting room and sees Yuzu sitting on the couch. She motions for him to sit next to him and he does. After a bit of uncomfortable silence, Yuzu finally speaks. "You've been through a lot Yuya."

"Yeah I have. Probably still going through some stuff since Yuto, Yugo, and Yuri are now a permanent part of me." Yuya says.

"I know what you mean. Serena, Rin, and Ruri are a part of me too." Yuzu says going from nervous to casual in her tone.

"You wouldn't know how to separate them or anything like that do you?"

"No why would I? The four of us were suspended in a container as energy all day before coming back."

"Good point. So what is it that you want to talk to me about and why in private?"

Yuzu then exhales and decides to get on with it. Though she does feel brave about saying it since her counterparts convinced her. With a small smile Yuzu tells Yuya.

"The reason why I want to talk to you in private is so no one can distract us. The dimensional war and the truth about who we were was nothing but stressful. It all became too much but I kept pushing through. And it's all thanks to you."

"Me?" Yuya points at himself.

"Yes. I knew you would keep trying to find me and stop everything. You're a determined person and unbelievably kind. Even if when you're at your lowest, you still continue to move forward and even if it takes a while, you do it with a smile. Those actions even made other people smile. That kind of attitude gave me hope that everything would be alright and I was right."

"You think too highly of me Yuzu." Yuya interrupts with his perspective. "The reason I kept trying was because of you Yuzu. I wanted you back no matter what I had to go through. Things got tough because everywhere I went it felt like the world was so apathetic and cruel. But I knew, just like you said, if I kept smiling and bringing smiles to others things would be better. Of course, things wouldn't be perfect until you were back and safe."

"And that's why I love you."

With that one sentence, Yuya was blown away. Yuzu, his childhood friend, loved him. It kind of made him froze for a second from surprise, which he got over because his counterparts quickly started rooting for/ordering him to respond.

"I love you too." Yuya responds with a big smile. "Always have and will."

Upon hearing that, Yuzu leans in a kisses Yuya, which he returns. They separate and let their foreheads touch while holding each other. During this their counterparts watch them.

"Well looks like Yuya gets his happy ending." Yuto congratulates.

"Looks like it though we're still merged with him." Yuri points out.

"Man he's lucky. Wish me and Rin could interact like those two." Yugo laments. Yuya heard that and thinks to himself, "Yeah, I wish you could too Yugo."

At the same time, Yuzu's counterparts were commenting on the sight.

"All right. Congratulations Yuzu." Rin cheered.

"Well they look happy. That's good." Serena comments.

"Seeing them makes me wish I could see Yuto again." Ruri yearns. Hearing that Yuzu thinks to herself, "I hope you do Ruri."

Suddenly Yuya starts glowing green and Yuzu glows yellow. After a bright flash, the glowing stops and sitting in their place in the same hugging position are Yugo and Ruri. The two counterparts look at each other in confusion.

"Yuto?" Ruri asks.

"Rin!" Yuya shouts as he then gives Ruri a big hug. One she breaks out of by headbutting the synchro counterpart.

"I'm not Rin! I'm Ruri!" Ruri yells.

"Huh. You're not Yuri. You're a girl." Yugo says which causes Ruri to start shouting that her names Ruri and not Yuri. Yugo can't help but think, "So that's what it feels like."

With all the shouting the two were doing they get attention of Reiji's security who look at them strangely.

Yugo and Ruri were taken to Reiji and Leo to see this sudden change in people. After the two explain to the Akaba's the series of events that led to this, Reiji hits on an idea. When he heard the part about what Yugo and Ruri wanted after Yuzu and Yuya's kiss as well as them adding from Yuya and Yuzu that they thought about them getting what they wanted too, he figures that they can switch bodies with any of their counterparts so long as main body and the counterpart inside them both wish it. They try this out by having Yugo and Ruri wanting Yuya and Yuzu respectively to appear. Nothing happens immediately, but moments later, they both glow red and change back into Yuya and Yuzu.

A couple hours later, Reiji and Leo Akaba have analyze and performed various tests on Yuya and Yuzu to see what is going with them and their counterparts along with this new ability to switch bodies. After looking over the data, they go to talk to Yuya and Yuzu, who both currently control the main body.

"We looked over all the results and here's what we concluded." Reiji explains to the two. "We believe it's possible to separate your respective dimensional counterparts from your bodies."

"Really!" Yuya shouts in surprise.

"How do we do that?" Yuzu asks.

"From what we've found, whenever you switch places, the main body emits a faint but unique energy signature. It's similar to the energy signature of the Arc Area Project but it's more accurate to say that's it's similar to the energy released by Ray and Reira when they separated Zarc." Leo explains. "The tests also show that the energy can be affected by interacting with one another and with various different interactions amongst the counterparts for an extended period of time can cause this energy to be strong enough, that in theory, you'll eventually become four people again."

"If you wish to separate your counterparts, here's what I suggest. For the next sixteen days, the two of you will spend most of a day together as a different counterpart." Reiji proposes.

"Huh, why 16 days?" Yuya questions the obvious since he wasn't all that good at math.

"Since the two of you are each technically four people in one, that means sixteen possible combinations of two counterparts interacting. I suggest you figure out a way to determine who will spend the day with whom and when." Reiji further expounds.

"Don't worry we can do that." Yuzu says.

"Oh also one more thing. During each day, have the counterparts duel each other." Reiji adds.

"Why? Do you think it'll help with the energy or whatever?" Yuya asks and Reiji just replies, "My theory is that a duel could enhance the energy especially since what separated Zarc and Ray into four people was from a duel. Plus, since dueling seems to solve most of our problems, it might help."
