Team Mystic's win in the Worldwide Supreme Tournament no longer seems to matter. Diego made a declaration to the world that his real goal was to find the six Malicious Fiends, and he managed to get his hands on five. It turns out that the last Malicious Fiend is in the hands of a duelist named Persephone, who turns out to be Dana that Diego somehow managed to take control of. Now all he needs is to find Raika and get his hands on the last Malicious Fiend. Yukina and her friends aren't going to stand for this. They plan to go against him, but...
"What?! What do you mean you won't let us go?!" Yukina questioned. Team Fanrong, Team Storm, and Team Mystic were planning to head straight to the Black Ace and put a stop to Diego's plans, but Justin is denying their request.
"Just as I said, Yukina." Justin said. "I know that I was the one that asked you and your friends for help, but the circumstances are different now. This is too dangerous to be left the hands of you children. Leave this to the adults."
"No way! I'm not going to stand here and do nothing while Dana is being used by that freak!" Marcus said.
"And we can't stand here while this madness is taking place." Yuxuan said.
"Exactly. We're aware of the danger, but we all still wish to fight." Jaw-Long claimed.
"We all saw the power they hold, and we're aware of how dangerous this is, but we're not scared." Sima claimed.
"Diego is a monster. He's made an insult, a mockery, and continues to misuse dueling for his evil purposes. He insults everything we stand for and must do something!" Yukina claimed. All of them felt the same way she did and kept on insisting of going.
"I understand how you all feel, but this is too dangerous. We don't know what they're fully capable of." Justin said.
"Everyone, look here." Sabaro said as he showed them to a monitor and showed the Black Ace's new headquarters. "We managed to track Diego to this location. This is the Black Ace's headquarters. The place might look like a small town, but it's really their entire facility. The tower in the center is the main base of operations. It's also in the middle of nowhere just outside the city."
"Sabaro, what are you doing?" Justin said.
"Sir, the Black Ace might be evil, but their official records claim they research and aid in the development of dueling. They're just another dueling research facility." Sabaro said. "Though they are evil, they haven't exactly done anything illegal. We really have no incriminating evidence against them to shut them down. Until we do, our hands are tied."
"That's always the problem with adults. You have to wait for something to happen rather than take action." Cray claimed.
"But we don't have the time to wait. We might have no choice but to take the fight to them." Sabaro said. "We can't allow Diego to get his hands on all six Malicious Fiends. We must also figure out how to stop this Persephone. She holds the strongest of the Malicious Fiends."
"Her name is Dana!" Marcus argued.
"I know, which is why we have to help her. Getting her away from the Black Ace will put their plans back." Sabaro said.
"So that's the plan. We have to get into their headquarters and try to get to her." Yukina said.
"Not to mention we have to wreck the place." Cray claimed.
"If we all work together, we can win." Yuxuan said.
"So that settles it. We're going." Yukina said as none of them are taking no for an answer. Justin was actually amazed with how brave they all are.
"Wait!" They all looked to the entrance and saw Chester and Stephanie were there as well.
"We want to go, too." Stephanie said.
"Really?" Yukina questioned.
"We don't know why Arthur joined forces with these people, but we want to go so we can learn why." Chester said.
"But we can't follow him this time. We feel the same as you and want to fight along side all of you." Stephanie said.
"Hold on. How can we really trust you?" Marcus questioned.
"At the moment, we have to. We're going to need all the help we can get." Yukina said. "What matters is that we save your friend and get the Malicious Fiends." She was right. Justin could see that he couldn't stop them.
"Very well. I can't stop you, so I'll have to trust you. Sabaro, they're going to need your dueling skills as well." Justin said.
"Yes, sir!" Sabaro said.
"In the meantime, I'll work with what I can to try to get the Black Ace shutdown. Even if you do stop them, Diego will just come back and maybe stronger than before." Justin said. "All of you must be careful." They all agreed to that. The tournament and dueling for fun is over. Now these duelists are stepping forward to protect their world and the honor of all duelists. All of them were on their way out with Justin and Li-Jing staying behind since they're not duelists. 'If they're really going, they're going to need a little more help.'
...
The Black Ace
With Persephone under Diego's control, she has the power to use the Malicious Fiend. However, Diego has other plans. She's not just using one of the Malicious Fiends, but was also generating some power that Diego can use. Persephone remained where she was and made sure the power of The Void kept going.
"Dana! Dana!" Snyder called as he came running into the chamber. "Dana! Are you okay?!"
"Who are you?" Persephone said with Snyder surprised. "Who is this Dana? My name is Persephone."
"Dana, what are you talking about?! It's me! It's Snyder!"
"I don't know you." Persephone said. That shot Snyder rather hard.
"Dana!" Snyder called.
"It's pointless. No matter how many times you call that name, she won't respond to it." Snyder turned around only to be grabbed by security and saw Diego there.
"Diego! What is this?!" Snyder shouted. "What did you to do, Dana?! Turn her back now!"
"Why are you so upset? I cured your friend just like I offered. She is completely healthy now." Diego said.
"So why is she Persephone?" Snyder questioned. "What did you do to her?"
"Your friend Dana was a true dueling prodigy." Diego said. "From the moment she could read, do math, and could wield a card; she had great skill in dueling. I knew someone like her would be perfect to wield the power of one of the Malicious Fiends. There were just two key problems. One was her health. With her body in the condition it was in, she couldn't endure the power. That's why I found the best medical treatment that could be used to cure her. The second was that she was too good. In order for her to use the power of a Malicious Fiend, as well as serving my needs, I had to find a way to make her my loyal servant. So, during the final steps of the procedure that was used to save her, a bit of brain surgery was done. A whole new personality was planted in her."
"A new personality?! That's crazy! How could you just give her a new personality?!" Snyder questioned. "Turn her back to normal!"
"I really don't understand why you're upset. I kept my end of the bargain." Diego said. "I never agreed to how I would cure."
"You're sick! Besides, if it was Dana you wanted, why did you recruit me?!" Snyder questioned.
"I knew you were going to be a problem with the treatments, so I offered you a position in Team Void until the time was right." Diego said. "Also, you being good friends with that Marcus made you the perfect weapon to use against him and Yukina's friends."
"So you used me to get to Dana!" Snyder said. He can't believe he fell for any of this.
"And now, you're no longer needed." Diego said and had security take Snyder away with Snyder begging to be released. "This power truly glorious." He said as he was amazed at his own achievements. "This power could generate an entire city. Just wait until I get all six." Diego was enjoying this until he got a call on his phone. "What is it?"
"Sir, others have been spotted heading to our building."
"So, they actually came. I knew they wouldn't leave things be." Diego said as he came prepared for them.
...
Yukina's Group
Yukina and all the others made their way to where the Black Ace's new headquarters were. They were able to make it to where Sabaro said and could see the place was just ahead of them.
"There it is!" Yukina said. "Boy, Diego has been keeping himself busy if he's able to have a place like that all to himself."
"That's where Dana and Snyder are. We've got to get them out." Marcus said.
"We will, but we have to be careful." Sabaro warned. "Diego is surely expecting our arrival. He always has contingencies in place. I might have infiltrated the Black Ace organization, but even I don't know all the ins and outs. They always seem to have a surprise waiting in the wings."
"Nothing ventured, nothing gained." Muyoshi claimed.
"Well? What are we waiting for?!" Cray said as he was ready to storm the place, but Hungwe held out his arm and stopped him. "What is it?"
"Come out! I can tell you're there, so you might as well show yourselves!" Hungwe called. He got what he asked for as something crashed down right in front of them. When the dust cleared away, they all saw it was Savage Titan.
"Malicious Fiend: Savage Titan?! That can only mean one thing!" Yukina said.
"Up here!" They all looked and saw that it was the Rodrigos with some other duelists of the Black Ace organization.
"I knew it! It's the Rodrigos!" Yukina said. "Watch yourselves, everyone. These guys are bad news because they're willing to hurt others just to win."
"Did you clowns honestly think we just let you infiltrate the place?!" Aaron said.
"We don't have time for you! Get out of the way!" Yukina called.
"No way!" Selena said. "This is a chance for us to kill two birds with one stone!"
"Didn't I mention that this is a chance to get payback at you, Yukina?!" Aaron said.
"When your team beat us, you ruined our chances at a better life. That was until we met Diego." Alonzo claimed. "He gladly offered us whatever we like. All we have to do is work for him, and he hates you just like we do."
"That's why this is as far as you go!" Aaron said. "Attack!" The Rodrigos and the security guards all attacked as they all played various cards to make sure Yukina and her friends are stopped. They all attacked with whatever was in their arsenal.
"Scatter! We're too big of a target like this!" Yuxuan called. All of them split in different directions, but the Rodrigos wouldnt let them escape.
"You're mine, Yukina!" Aaron called as he had Savage Titan attack her, but Sabaro jumped in and got her out of the way.
"Yukina, are you okay?" Cindy asked.
"I am. Thanks, Sabaro." Yukina said.
"You're not safe! Im getting payback from that defeat you and your team served." Aaron said.
"Nutcase!" Yukina said as she summoned out her unicorn with Sabaro and Cindy helping her out.
"Herculean Warrior!" Alonzo called as he attacked Cray and his team. "I'll crush you!"
"Don't count on it. You dont have the strength to crush me!" Cray called as he unleashed his Storm Dragon. As for Selena, she was facing Marcus And Team Camelot.
"End of the line." Selena said.
"No way. Now i get to pay you back for last time." Marcus said.
"And what makes you think this will be any different?" Selena questioned.
"From what I've seen, you're nothing! Now out of the way!" Chester called as he attacked. As for Team Fanring, they were taking care of the lightweights through martial arts instead of dueling. In fact, Yuxuan tried attacking Alonzo himself, but Alonzo moved out of the way in time.
"Hey! That's a cheap stunt!" Alonzo complained.
"You and your siblings have no pride or honor as duelists, so you will mot be treated as such!" Yuxuan claimed and continued to attack. Everyone is fighting as hard as they could, but the Rodrigos are being persistent and won't let them through.
"We don't really have time for this!" Cray said. "If you know what's good for you, you'll get out of the way! Storm Dragon!" He unleashed the raw power of his dragon. His dragon unleashed powerful winds and tore through everything for an opening to be created. "Good! Let's go!"
"You go, Cray! You're one of our strongest!" Sima said. "We'll stay here and hold them off!" Cray was good with that as he went on ahead and went to the Black Ace's base.
"I don't have time to be wasting with these clowns! I got to get to Dana!" Marcus said.
"As if! You're not getting through me!" Selena said as she was holding a strong stand against them.
"If brute force won't get you to move, we'll just have to get around. I play Swords of Revealing Light!" Stephanie claimed. She played a powerful spell and completely blocked off all of the enemies attacks.
"No fair!" Selena complained.
"Let's go!" Stephanie said as she, Marcus, and Chester hurried straight to the base.
"Stop!" Selena called as she still attempted to stop them.
"Something to remember us by!" Chester said as he played another card and foiled Selena's last attempts. Now four of them were on the way to the base. As for Team Fanrong, they were still fighting off the other duelists.
"It looks like some of us made it through!" Jaw-Long said.
"Yeah, but they're going to need help. Yuxuan, you should go." Muyoshi said. "They might need your skills in there."
"Are you sure? I can't leave you two behind." Yuxuan said.
"Don't worry about us. This is what Fanrong trained us for." Jaw-Long said.
"I think this is the best time to see what Fanrong really taught us. You have to go!" Muyoshi said. When he put it liked that, Yuxuan agreed and ran straight for the base himself. However, some of the guards got in the way and attempted to stop him.
"Don't be foolish!" Yuxuan said as he forced his way through and knocked them all aside like they were dominos. Now five of the duelists were heading straight for the Black Ace's base.
"It looks like they're making it!" Yukina said.
"But you won't get so lucky!" Aaron said as he and his titan are kept her from going anywhere. He had his titan attack her, but Yukina jumped out of the way. "I'm not letting you go anywhere!"
"Move it!" Sabaro called. He had Master Diamond attack and tried to hold Savage Titan back. "Yukina, get going! I'll stay behind and take care of this creep!"
"I'll stay and help Sabaro out!" Cindy said.
"Right! Be careful!" Yukina said and hurried off.
"I won't let you escape me!" Aaron called as he attempted to fight back, but Sabaro wasn't letting him going anywhere. Yukina was able to get around and was going to join the others. "I said you're not going anywhere!" Suddenly, Aaron and Savage Titan unleashed a burst of destructive power that blew Cindy and Sabaro back with Yukina getting caught in it as well.
"Oh man. That guy is brutal." Sabaro said.
"What about Yukina?!" Cindy said. It wasn't good at all. That sudden explosion knocked Yukina off her feet. She attempted to get back up, but Aaron suddenly stopped down on her arm and kept her down. The others looked back and saw Yukina was in trouble now, but they won't reach her in time.
"You let your guard down! Again!" Aaron mocked. "I told you I get payback!" He claimed as he stomped down on her arm with her screaming in pain. "As payback, I'm going to make sure you never duel again!" He claimed as he was grinning from Yukina's pain. He was actually attempting to break her arm as he raised it as high as he could.
"Are you psycho?!" Yukina said.
"Maybe I am, but the fact is that I win! I win!" Aaron shouted as he was really going to do just that and ruin Yukina's dueling days.
"Get off her!" Aaron was suddenly attacked out as Domitanius came at him and knocked Aaron away from Yukina like it was a direct attack. Yukina was able to get back and saw who launched the attack. "Yukina! We're here!" It was none other than Felix and Kent.
"Did you miss us?!" Kent called.
"Felix! Kent! You're okay!" Yukina said as she was so glad to see him again.
"We know all about what's going on! Let's get that Diego!" Felix said. Yukina was so happy to see them again, and even happier that they'll fight with her and the others. "Let's go!" All three of them got back in it and headed straight for the Black Ace's base. With these eight powerful duelists, they might really have a chance to beat Diego and his forces.
...
Diego
"Sir, eight of the intruders managed to get around the first line of defense and are now entering the facility."
"Those little rats just don't know when to give up." Diego said as he was able to monitor all that was going on. "Very well. I have something ready for them. As soon as they enter the perimeter, throw up the forcefield."
...
Yukina's Team
All eight of them were able to make it to the facility and could now get in without the Rodrigos getting in the way. All eight of them made it inside, but something happened the moment they did. As soon as they crossed in, they saw energy rise up from behind him and appeared to be closing in with it covering the whole place like a dome.
"What was that?" Marcus questioned. Felix looked back and had a look with him pressing against solid energy in the air.
"I think it's some sort of forcefield." Felix said.
"And he decided to throw that up now?" Kent mocked. "What a dope Diego is. He should have turned that on, but now we're in here. Too late."
"I don't think it's meant to keep us out. I think it's meant to keep us in." Yukina said. "Diego does take pleasure in our pain and suffering. He must be pretty confident we can't stop him and is trying to keep us his prisoners."
"Let's make our way to the tower in the center. That's where everything has to be going on." Felix said. They all agreed to that and got going, but suddenly stopped when they saw someone standing in their way. Stephanie and Chester were the most surprised as they saw it was Arthur doing just that. How could Arthur work for the likes of the Black Ace? Has the darkness of his Malicious Fiend taken him over?
