--AUTHOR'S NOTE: This chapter suggestion idea was suggested by BladeKnightmare --

Yuya Sakaki and Celina had both been knocked out unconscious, their bodies were both lying down on the grassy ground outside at Yuya's home dimension-- The Pendulum Dimension.

Yuya's body got back up on his feet. "What happened? Wait, my voice? Why does it sound like--" he gasped when he saw Celina's body lying down. "Ahhhh! Why is my body over there!?"

Celina's body woke up, "Hey! What's with all the loud ruckus!? Why are you being so loud? You woke me up." 

"AHHH! This is not happening!" Yuya was freaking out, moving side to side.

"What the?" Celina got up from the grass. "Huh? You are in my body?" she pointed to Yuya. "Then, that means?...." sudden realization struck her--him. "I'm in your body, Celina! How did this even happen!? OH NOOOO! I don't want to be a girl! That's my worst nightmare! I already have to deal with Zuzu and her fan. And trust me, that is completely enough for me to deal with... Thank you. You never want to deal with her when she's mad. She can be quite scary."

Yuya (aka Celina inside) smacked Celina (aka Yuya) on her head. "You think I want to be a boy in your body!? I don't want that either." he took his hand away. "But you don't see me, complaining about it. I would rather have my body back, too."

"Okay..I deserved that." Celina said, teary-eyed, rubbing her head. "You're right. But how do you think we both switched bodies, just now?"

Yuya and Celina had both switched bodies. So, Yuya was in Celina's female body. While, Celina was in Yuya's male body.

"I don't know. But I don't remember anything?" said Yuya. "Do you?"

"Nope. I don't recall anything. We both just woke up now. I think we were both unconscious, it could explain why we don't have any memory of it. But that still doesn't explain why we both somehow switched bodies with each other?" said the Celina-body (Yuya). 

"We can't just stay like this forever. We have to get back to our bodies somehow." said the Yuya-body (Celina). "Hey, why don't we duel now? To see if we can get any ideas about fixing this?" he took out his pendulum duel disk. 

"Sure. Why don't we find out?" asked Yuya in Celina's body,  getting ready to duel. "Let's duel."

------------------------------------------------------
[After The Duel]

"That was a great duel." said Yuya (Celina). "Have any ideas?"

"Yes. I actually have one idea now. That we could try," said Celina (Yuya).

"You do? And what would that be?" asked Yuya (Celina).

"We could go tell and ask Declan about it. He's smart. And knows a bunch of knowledgeable stuff. I'm sure that he can help us out." said Celina (Yuya).

"Good. That's a great idea! Let's go!" Yuya (Celina) took Celina (Yuya's) hand, and started running really fast, making her/him blush. "Why are you going so fast?"

"We have to! I mean, wouldn't you want to get your body back so fast?" said Yuya/Celina.

"True. I understand, what you mean by that. We can't afford to waste anymore time now. It might be the only way." said Celina/Yuya.

------------------------------------------------------------------------------------------------------------

"You both switched bodies! So, Yuya is in Celina's body. And Celina is Yuya? My word. That's something that I wasn't  quite expecting." said Declan.

"So, Declan. Can you do it? Can you get our bodies back?" asked Yuya/Celina.

Declan Akaba got up from his computer chair at his desk in his office. "Yes. Sometimes, this sort of thing can happen with some sort of magic crystals from another dimension that are near the two people. Causing them to switch bodies. But this appears to not be the case. For, there seems to be no signs of magical rock in sight. So there is another way you can reverse this."

"How can you reverse it?" Celina's body said (Yuya). "We are both willing to do anything to get our own bodies back again. So, what is this way?"

"There is one last way. You both must perform some sort of happy expression to yourselves together, so that it puts you two in sync, combining your energies into one. And this sort of expression must be heartfelt, it must come from both of your hearts. It has to, so that it builds up a lot of energetic fuel. As people say, your heart can be an energetic gateway to another dimension or to do with energy. Even, quantum jumping, quantum physics. It should help you both shift back into your current-original bodies. All you need is a heartfelt desire and a pure intention of your heart for that to happen. Do I make myself clear?"

"Yes, Sir. We understand." Yuya and Celina both said in unison.

"Good. Now, I have some important business to attend to. I got to leave now, to go some meeting." Declan said and left his room. "Bye."
------------------------------------------------------

"So, Declan said that in order for us  to both go back to our own bodies. Then,  we must do some sort of happy expression that comes from the heart. And there must be something that both of us are aligned with at the same time with our energies. So, that we can both become one." said Celina (Yuya). 

"Yes. But it sounds pretty weird to me." said Yuya (Celina). "I wonder if it can work in some form. If we both try dueling each other again?"

"You know. That may just work. Why don't we both give it another shot?"  said Yuya in Celina's body.

Even though they both dueled. Nothing happened. They were both disappointed in themselves. 

"I can't believe that duel didn't work at all. That is such a shame. What do we do now?" said Celina in Yuya's body. "I don't want to give up. I refuse to!"

"I know. So do I." said Yuya in Celina's body. "But you know, seeing you duel out there. Well, in my body. It looked odd to me since it was like I was seeing myself in first person. It was like I was watching myself duel in my own perspective. But at the same time, it's not. Because you are you. Celina. And, I am me. Yuya. Even if we both are in different bodies that we aren't used to." she/he grabbed Celina's hands (that was from Yuya's body). "It doesn't matter what we do. It's how we feel in the inside that matters. That is what is more important. I can still sense that you were being true to yourself, even if you are in my body."

Yuya's eyes gazed back at Celina's eyes. "That's why I don't care what body you are in! Because I love you for your soul, Celina. I like how you never give up on anything. I like how you keep on striving forward. And, spending some time with you has made me deeply admire that rebellious side that you have for justice. I like that so much about you." Yuya (in Celina's body) kissed Celina (who was in his original body). 

The moment that their lips touched and kissed back each other, they felt a long breeze of wind sweep by them, making their hair wave around in the air for a bit. They also felt an instant shift of energy, making both of their souls switch back into their original bodies.

Celina and Yuya were both back in their own bodies!

"Yuya." said Celina, blushing. "That was very thoughtful of you to say to me. No one has ever said something like that to me that was so moving...that it made me feel what you said about me dueling in your body. I felt something like that too, when I saw you dueling with a smile. It's like I can feel all the love in it."

Yuya then gasped, "Wait, love! That's it! That was the key to switching our bodies back in an instant. It was the pure love of our souls together, doing something happy and heartfelt to express it."

"Yes. Apparently, it is." replied Celina. "I guess that means we both loved each other in some way for that to happen? Because it worked?"

"Yeah. Do me a favor. Let's just keep this a secret between us. If Declan asks us what we did to get our bodies back, don't mention it was because of our kiss and love for each other that made it work. Since, it's really sappy and kinda embarrassing." Yuya chuckled in a nervous tone. "If anyone asks, we will just tell them that it was our dueling that brought us back together."

"Sure. Whatever you say." Celina playfully punched Yuya's arm and winked back at him. "I don't have a problem with that. I mean, I would feel embarrassed to talk about it too." she then kissed Yuya on his cheek, making him blush. "But no one says that we both can't date each other now. Right?"

"Um...yeah." Yuya turned red. "Right." he smiled back at Celina.
