The Black Ace organization... It's an organization that intends to use the powers found in dueling for malicious purposes. They attempted to have the most powerful duelist under their command with Raika and only one Malicious Fiend. Then, during the Worldwide Supreme Tournament, they were able to find other Malicious Fiends and continued their pursuit of power. Diego, the head of the organization, is still at large and is to be considered a wanted criminal. He now currently holds four Malicious Fiends with duelists that are just as vicious and malevolent. Currently, they have a new hideout since their other ones were all wrecked.

"What's taking so long?" Aaron questioned as he was getting impatient. "The tournament is over and yet he's keeping us away from the action. I want to get out there and get those punks. I start rising to the top."

"Chill, Aaron." Selena said.

"She's right. Working for the Black Ace is the best thing that has happened to us." Alonzo claimed. "Just try to be patient and wait for Diego to give us orders."

"Honestly, you seem to have no class or sense of style and grace." Vincent claimed. "Can't you try to act a little more civilized or sophisticated?"

"What does any of that have to do with anything?" Aaron said. "The only thing I need is to crush anyone who gets in my way, and I need a way to blow off some steam. I still haven't forgotten what Felix and his friends did to me. I couldn't care less about what Diego is plotting or anything. I want to get those guys."

"And you'll get your chance soon enough. I too desire payback at Yukina." Zash claimed. "However, for our needs to be met, we must have the six Malicious Fiends. Right now, we only hold four. You should spend that energy trying to be more efficient to us. If it wasn't for the fact that you did hold a Malicious Fiend, you would be nothing to us."

"Do you want to fight?" Aaron said as he was ready to rumble. Just then, the doors opened up and Diego came walking out. "About time! Are you going to let us out and let us do what we want or not?! I'm sick of waiting for you to give orders! You take way too long to make a move!"

"Calm down, Aaron. All good things come to those who wait." Diego said. "Let's just say that I had an important meeting to attend to. Right now, we need to think of how we're going to get our hands on the remaining two Malicious Fiends. Seeing as how Raika and Arthur refuse to join us, we'll have to take the cards by force."

"You should have taken those cards from them when you had the chance!" Aaron argued. "For some diabolical mastermind, you're not all that smart."

"Just be patient, Aaron. You'll get your chance soon enough." Diego claimed.

...

Cray

"Go! Go, Storm Dragon!" Cray called as he was training as intensly as he could. Cray still has his sights set on defeating Yukina. Nothing about that has changed. Whatever Cray was doing seems to have worked for him. The power he's emitting was grand.

"Oh yeah, Cray! You're on a roll! There's no way Yukina can beat you now!" Kent claimed.

"I hope you're right. Maybe it's time I challenge her once again." Cray claimed. He felt he was ready to take her on again. Then, it was at that moment that ue was being called by Yukina herself. "Well, just who I was thinking of." He said when he answered.

"Cray, come to the WDA. Both you and Kent should come." Yukina said. "There's something we need to talk about." It sounded serious, and that didn't sound like Yukina. This must be important.

...

The WDA

Ever since Yukina had that strange encounter, she can't shake the feeling that it was so real and that the Black Ace is going to make another move. If what she experienced was real, this could be the chance that they've been looking for to destroy the Malicious Fiends. That's why she went to speak with Justin and Sabaro at the WDA. They all waited for Cray and Kent to show up. When they did, they saw Yukina was there with Felix and Cindy.

"Nice of you two to finally join us." Felix teased.

"Put a sock in it. What's so important that you had to call us here?" Cray said.

"Yukina just told us something interesting." Cindy claimed.

"Let me see if i have this right, Yukina." Justin said. "You had a dream where duel monsters were real. Their world is in danger because of some evil, and it has something to do with the Malicious Fiends?"

"It's not just them. It will be our world, too." Yukina claimed. "It also was no dream. I'm sure of that."

"What's going on? Did you hit your head or something?" Cray said with him already annoyed. "You pulled me away for this nonsense?"

"It's not nonsense." Yukina debated. "As we all know, the cards we play in our game hold great power. Greater power than we mere humans could have ever imagined. We've seen that in a darker version with the Malicious Fiends. They can produce real damage, and the effects they have on us are real as well. Those cards hold darkness and evil. Now, that same kind of power is stirring. We can't leave it unchecked anymore. I don't know where to start, but we all agree that the Malicious Fiends are dangerous, and the Black Ace must be stopped once and for all."

"I certainly can agree on that." Justin claimed. "Ever since the Black Ace made themselves known with Duel Battlers, we've done our best to keep tabs on them. Local authorities are well aware of some of their actions and have been keeping an eye out for them as well. The power of just one Malicious Fiend is dangerous, but the power of all six together could cause devastating effects on our world."

"Luckily, we know that one of them is the hands of Arthur." Sabaro said. "He may have temporarily aided Diego, but he came around and was able to take his Malicious Fiend with him."

"But Diego wouldn't take that lying down." Felix said. "If he wants all six Malicious Fiends, he'll go after Arthur again and get that card however he wants."

"And don't forget Raika. He still has Life Destroyer with him." Cindy claimed. "They both might have severed themselves form the Black Ace, but they might go after them again.

"So, what are we talking about doing here?" Kent questioned.

"We have to do something about the Malicious Fiends, and that will help bring the Black Ace down." Yukina said. "Their whole plans revolve around those cards. We can't just keep waiting for them to make a move. We have to bring the fight to them."

"Ha. Now you're starting to make sense." Cray said.

"I understand what you're saying, Yukina, but where do we even begin?" Justin asked.

"If we just knew more about the Malicious Fiends, like maybe where they came from, or something about them we don't know; we can act." Yukina said. "At least that's what Gearfried said, but all he told me is that we would know what to do." They all thought she was crazy again for the last part, but she did have a valid point.

"Perhaps there is something we didn't think about." Sabaro said. "What about where the cards were sealed away? Some ancient tombs put up warnings or legends about the treasures that were kept inside."

But there wasn't much of anything in the cave Life Destroyer was kept in." Felix said.

"No, but we know there had to have been other places." Yukina said. "We may not know how Diego managed to get his hands on all of them, but maybe there's something we can use at one of them. We just need to find out where."

"An interesting idea." Justin said as he thought it over. "Those cards must have an origin. Finding out where they have been prior to when Diego got them could actually help us. Of course, it's going to take time and research."

"That might be something we don't have." Yukina said.

"I can't believe this. I can't believe how scared you're all acting." Cray said since he sounded most unsatisfied. "What are you all making a big deal about? After what we've been through, they're just cards. We've taken care of them before, and if they come back, we do it again. They're just in the hands of another set of duelists, and any duelists will just simply take them on. In fact, I welcome the challenge to take them all on again."

"That's right! What is there to worry about?!" Kent said. "Just leave it all to Cray!"

"It's not that simple." Yukina said.

"It sounds rather simple to me. You calling me here was just a waste of time because we already know all of this." Cray claimed. "I'm out of here." He just walked right out and thought this was just a waste. Clearly, Cray hasn't let go of his desire to beat Yukina and is focused only on that.

"Cray, wait!" Kent called and was about to go after him.

"Kent, leave it. You need to stay here because we might need your help. You understand how important this is." Felix said.

"I know all of this sounds crazy to the rest of you, but I'm being serious about this." Yukina said. "I believe that the Black Ace is going to make their biggest move yet, and everything they've done revolves around the Malicious Fiends. This time, we need to get ahead of the Black Ace before they make their move. We can't let them be one step ahead of us this time."

"I agree." Felix said. "We all know how dangerous they can be, and the lengths Diego will go to for him to get what he wants."

"Sabaro, you infiltrated the Black Ace before. Have you ever learned why Diego is doing all of this?" Cindy questioned.

"No. Nothing on Diego's motives or how he is even capable of all of this. At least not during the time I was undercover." Sabaro claimed.

"Justin, can't you see that this has to be done?" Yukina said. "Please help us."

"You don't have to convince me. I agree that the Black Ace is a threat that must be dealt with." Justin said. "I spoke with several others on this matter, but it's difficult to say exactly if they've done anything really illegal."

"Seriously? Knowing what they've done, you don't call it illegal?!" Kent said.

"Regardless, it doesn't do much good with Diego in the wind, and he's the head of the Black Ace." Justin said. "Knowing what they are doing and convincing a jury that they are responsible are two different matters. Besides, it doesn't matter if we can't find Diego to bring him in. However, you're idea to find where those cards have been in hopes of finding ways to be rid of them does intrigue me. If we're really talking about putting an end to the Black Ace's plans, I think we should keep our focus on that. We'll be able to do more with that."

"Now we're talking about getting somewhere." Yukina said with her liking the sound of that.

"We're going to need time to gather whatever intel we can. Once we have at least one location for you to investigate, we'll call on you and your friends to check it out, Yukina." Justin said. "Your group understands what we're up against better than anyone. So, be ready to move when you can."

"We don't really have to do that much. If we can get in contact with Arthur Lance, he can tell us where he got his Malicious Fiend and investigate around there." Sabaro said.

"Sounds good to me." Yukina said.

"Right. Since it's the Black Ace, we can't go so easy on them." Cindy said.

"And don't worry about Kent. I know he'll come and help us." Kent said.

"We can also contact the friends we've made around the world. Some of them are willing to help us in this." Felix said.

"Good. It fills my heart with joy when I see duelists like yourself fight for what's right." Justin said. All of them seemed ready for a fight, but Felix was concerned about something.

'Yukina's instincts are usually pretty sharp, so I believe her when she says something's going on.' Felix thought. 'I just have this bad feeling that whatever we're up against is going to be a lot worse than anything we've faced before.'

...

Diego

Meanwhile, Diego was making plans of his own. Despite his subordinates getting a little restless, he had everything under control. What no one knew was that he always had his own room that appeared to have mystic symbols written on the wall. He dropped down to a knee and a purple flame ignited.

"They're inner darkness continues to grow. We're still searching for the remaining two, but everything will soon fall into place. It will be time very soon...Master." Diego said.

"And my resurrection will soon be at hand."
