"You all saw it here!" Marcy announced. "Yukin has won with a great comeback victory!" Everyone in the city watched it and loved seeing Yukin win against Shun. Shiro, Jirobo, Rishi, Nova, and Nene all knew that he would find a way to win.

"So, what next, Yukin?" Shun asked.

"I'm not really sure. I have to figure out a way to bring the people together." Yukin said. "I've been to Neon City and there's also here in Nitro City, but where to next?"

"That's not all you have to do." Brui claimed. "If Drewsin really is alive inside of you, there must be a way to bring him back, right? You were together before, but you were able to break apart."

"And if that's true, maybe Huo has to be as well." Rini said. They both have hope that they can see their dearest friends again. There's still much to do, but maybe not as much as Yukin and the others might think. That was when Yukin's duel disk was going off and alerting him of a message he had.

"Yukin, do you read me?" Renji asked.

"Yeah, Renji. I hear you. What is it now?" Yukin questioned.

"You've done quite well." Renji claimed. "Your duels against Klaus and Shun have had excellent results. Their faith and trust in you is rising and things are looking well. Teleport back to Merge City for your last challenge. Only one more win against a powerful duelist should do the trick."

"Only one more?" Zoey said as it seemed like all the strife, all the anguish, and all the struggling they all had to endure finally seems like it will come to an end.

"Well, let's go and finish this." Yukin said. The girls grabbed a hold of him and the five of them teleported once again.

"Only one duel left and it seems like everything with Promin Academy will finally be over. It's hard to believe." Roxanne claimed.

"And if anyone can do it, Yukin can." Jordan said as all of them were putting their faith in him.

...

Merge City

Yukin and the girls teleported back to the stadium. Once there, they saw everyone was still around and waited for this final duel.

"Well done, Yukin." All of them looked and saw Renji was there in person this time. "You've dueled well and it's really uniting the people. Now, your last challenge awaits. Only one more duel for you to win. Not only will this complete your mission, but you will also obtain your dream and go pro."

"And there's only one reason you're standing in front of me and telling me this." Yukin said as he braced himself. "You're my last opponent."

"That's correct." Renji said. These two were facing each other once again. There was quite a rivalry, and despite how Yukin didn't trust Renji at first, Renji proved himself to be quite a duelist and a leader. He played a large part in the war against Promin Academy.

"Renji is going to be his final opponent?" Zoey said as she was rather nervous.

"Is that bad?" Brui asked.

"Renji is one powerful duelist. I've seen them duel against each other before." Siri said. "Renji countered him at every step."

"That's what happened when they dueled for the first time." Zoey said. "If there wasn't a problem in the system, Yukin would have lost back then."

"This guy is really so powerful that even Yukin has a hard time against him?" Rini said. Everyone could see that this won't be an easy duel.

"Zoey..." Yukin said and got her attention. "You and the girls need to keep back. You know what might come of this duel." Zoey understood and she and the girls moved back. 'Renji... Out of all the duelists I've faced, he is clearly the strongest. I've never been able to beat him once. He was even able to create his own elemental cards, taking it a step further before I could. This duel will be my greatest challenge yet.' He thought as he fully understand what he's getting himself into.

"Do you really think Yukin can beat Renji this time?" Sylvester questioned as he watched in the stands with the others.

"I hope so." Siegrain said.

"Yukin is going to be in a real pickle here." Nate said.

"But he has to win." Alyssa said.

"I just hope he'll be okay." Augustus said.

"He will." All of them looked and saw that Ristly was joining them in the stands. "Yukin always has a way to pull it off." This is certainly going to be one intense duel.

"Are you ready, Yukin?" Renji asked.

"I've been ready to settle the score with you for a long time." Yukin said.

"Of course, it's only fitting that we use your father's creation, the reality generator, to have this duel." Renji said. "In fact, I already selected the field for our battle." He snapped his fingers and the reality generator, a generator that changes the field and causes more realistic effects to make duels more exciting, activated and changed the field around into a street of buildings and lights. Yukin instantly recognized it.

"This is..." Yukin said.

"Yes. It's Neon Street. This is where you and I had our first duel, but we never finished it." Renji said. "What better way to settle everything?"

"I couldn't agree more." Yukin said. He reached inside his shirt and pulled out his complete medallion. "This is where it all comes into play. Ready, Renji?"

"I am." Renji said. The two of them activated their duel disks and were set to go. This is where everything falls into place. This duel was also being broadcast for everyone in Neon and Nitro City to see. It's time for it all to end.

"Let's duel!" Both of them said as they were starting with 4000LP.

"I'll be the one to start this." Yukin said as he was making the first move. "I'll start this duel off by summoning Card Lizard to the field!" He summoned out his lizard as it came up with 1000atk points. "When Card Lizard is summoned, I can draw two more cards!" He said as he drew two more cards. "One of them happens to be my favorite spell: Variation!" He said as he played it. "With it, I can summon any monster from my hand as long as each monster is a different attribute! I'm summoning four monsters!" A bright light shined and opened the way for four monsters to show.

"Four monsters at once?!" Siegrain said as that was amazing.

"He's really not pulling any punches!" Sylvester said.

"First, my light attribute: Soundwave Tuner!" Yukin said as Soundwave Tuner appeared with 0atk points. "My earth attribute: Change-o Chameleon!" His chameleon appeared with 1100atk points. "Dark attribute: Dark Balancer!" His balancer appeared with 2000atk points. "Finally, my water attribute: Mystic Syren!" He summoned out a new monster that looked like a blue mermaid-like creature with purple fins on her arms and long blue hair. She also had 1700atk points. "Since Soundwave Tuner was summoned, I lose a 100LP while you gain a 100LP!" Soundwave Tuner caused a change in life points with Yukin's dropping to 3900 and Renji's rising to 4100. "I now have all I need! I combine the forces of fire with the forces of water! Come together as one!" Fire came around his lizard while water came around his syren with the two coming together. "I elemental summon a sapphire attribute! I summon Sapphire Serapho!" Serapho appeared on the field with 2500atk points.

"And I take it you aren't done." Renji said.

"Far from it!" Yukin said. "Thanks to Dark Balancer's ability, I can bring back a monster that was used as material to summon a monster that came from my extra deck! I'm bringing back my Mystic Syren!" Dark Balancer opened up a portal and Yukin's syren came out of it. "With that done, I now activate Equilibrium!"

"He usually uses that to bring out Shadow Sapphire Serapho, but how does he plan to use that now?" Siri questioned.

"I think I know." Rini said as she could sense what was coming.

"With my spell, I'll change my chameleon into a level six just like my Dark Balancer!" Yukin said as the level of his chameleon matched his Dark Balancer. "I now tune Soundwave Tuner with Change-o Chameleon!" The synchro process begun as he used his two monsters in it. "Fly high and generate a whirlwind! I synchro summon Tempest Tenrun!" Tenrun joined the field as it flew out. "Dark Balancer's ability activates again to bring back my chameleon!" His chameleon rose back on the field "My Dark Balancer has one other ability. If he's one of the monsters used, I can fusion summon! So, I'll change Change-o Chameleon into a dark attribute!" His chameleon's ability changed it's color to purple.

"Two dark attribute monsters... I know who is coming." Siri said.

"I now fuse Dark Balancer with Change-o Chameleon!" Yukin called as the two of them began fusing together. "When the darkness creeps near, this monster is the embodiment of fear! I fusion summon Venom Vondoon!" Vondoon joined in the battle as it appeared on the field.

"With those three, I bet I know who is next." Brui said.

"I now activate Mystic Syren's ability! She can use her alluring voice to call on a level four or lower monster!" Yukin said as his syren started harmonizing. "I summon Crater Cobra!" He said as he summoned out his snake with 1200def points. "I now overlay Crater Cobra and Mystic Syren!" The two of them became orange and blue energy as they came together in a sparkling vortex. "From the shadows and controls the dark, he shows no mercy to his enemies! I xyz summon Shadow Shudamin!" The final piece came on the field as he now had all four. That amazed the crowd.

"Amazing! Yukin performed four different kinds of summoning in one turn, and it's only the beginning!" Nate said.

"That's incredible!" Augustus said.

"Let's see Renji top that!" Alyssa said.

"The duel is just starting." Sylvester said.

"Yeah, and Yukin already used every card in his hand." Siegrain said. "It's a little early to get so excited."

"Hey... Didn't Renji do the same thing when these two dueled for the first time?" Eli questioned.

"I think he did. I guess Yukin's trying to take control like Renji did." Siegrain said. The duel just started and things are already getting tense.

"Very nicely done, Yukin." Renji said. "You pulled off so many summons in one turn. The work of a true professional, and I should know. It's my turn!" Renji said as he used some fancy moves and climbed to the top of a building. He drew his card and planned to try the same as Yukin. "By dropping this monster's attack points to zero, I can special summon it! Appear, Dimensional Bahamut!" He summoned out a dark dragon with a humanoid body. It had 3000atk points, but they dropped all the way to zero. "Next, I play Portal of Deception!"

"You played that in our first duel." Yukin remembered.

"Excellent memory. So, I'm sure you remember that I can add a Dimensional monster to my hand, but summoning it means I will take a thousand points of damage during my standby phase." Renji said. "I'll add my turner monster: Dimensional Butterfly." He said as he took the card. "In fact, I'll summon it to the field!" He summoned out a butterfly-like creature as it had 100atk points.

"Renji played it like this last time. He had a way to counter the effects of him taking damage from his own cards." Zoey said.

"If that's a tuner monster, he's going to synchro summon." Rini said.

"I now activate Dimensional Bahamut's other ability! It allows me to special summon another Dimensional monster from my hand!" Renji said.

'I could use Tempest Tenrun to stop that... No. I better wait to see what he does.' Yukin thought.

"Rise, Dimensional Leviathan!" Renji summoned out another monster as a blue leviathan-like creatures emerged on the field and had 2900atk points. "I now activate Double Dimension Portal! I'll lose 2000LP on my next turn, but I can now special summon two level four or lower monsters! I'm bringing out Dimensional Imp and Dimensional Vixen!" Renji summoned out his imp with it having 300atk points and a lady with fox-like features with her having 1300atk points. "I now activate my vixen's ability to change her level to match my level eight bahamut." He said as his vixen turned into a level eight monster. "I now have all that I need."

"For what?" Yukin questioned.

"For this! I'll start by overlaying my level eight Dimensional Leviathan and Dimensional Bahamut!" Renji called as his two monsters became blue and purple energy and came together. "His darkness causes him to rule over all, striking fear to those who oppose him! I xyz summon Dimensional Dark Warrior Mordred!" He summoned out a black armored warrior with a black cape. It was coated in energy, but it looked like it was being pulled into his chest. Almost like darkness being pulled into a blackhole. it also had 3200atk points.

"He xyz summoned!" Brui said.

"And he's not done!" Zoey said.

"I now activate Portal of Tragedy!" Renji said. "I'll have to pay 1000LP on my next turn, but I can now remove monsters from my deck for a fusion summon. The summoning conditions are two level five or higher Dimensional Monsters, so I'll remove Dimensional Golem and Sphinx from my graveyard." He said as he removed both his monsters and they began fusing together. "With force and pressure, victory will be assure! I fusion summon Dimensional Gravity Warrior Feirefiz!" His two monsters fused together and summoned out a brand new one. This one wore shiny silver armor with him carrying a mallet. Energy could be seeing flowing down it like gravity and had 3300atk points. "Finally, I'll tune my level one Dimensional Butterfly with my level eight Dimensional Vixen and my level one Dimensional Imp!" He started the synchro process with three monsters and it worked as a powerful beam shot through. "Let your light shine and for all to bask in your glory and authority! I synchro summon Dimensional Light Warrior Arthur!" His third warrior appeared with white armor and a cape and crown, looking like a mighty king with it carrying a broadsword. It had a total of 3500atk points.

"Look at all those monsters!" Siri said.

"How is Yukin going to beat those things?!" Zoey said. Renji was able to match Yukin's opening moves and brought out three powerful monsters on his first turn.

"These three are my most powerful warriors! How will you fair against them?!" Renji said as he's already issuing the challenge. How can Yukin beat his greatest rival?
