Yubel had transported Jaden and his friends to Dark World, where Jaden became the Supreme King. Here, they will talk to the Supreme King himself about Axel's death.
"Just like it was last time we were here. Dark, lonely, and scary." said Syrus.
"Don't worry, Syrus. We'll be out of here in no time." said Atticus.
"Remember, guys. If we get caught, we're dead." said Jaden.
"Hey, look! I can see the tower from here." said Aster. Jaden looked up at the tower. Bad flashbacks from when he was the Supreme King still haunted him even today.
"That's it. Let's go see if he's home." said Jesse. But Jaden stopped him.
"Are you nuts? We can't just barge in. We need some disguises." said Bastion.
"There's no need. All we need to do is defeat every fiend we see in a duel. The Supreme King will come to us." said Zane.
"Okay, Zane. You lead the way." said Jesse. They all followed Zane towards the tower. Once they got to the entrance, they stopped.
"I can see a couple of guards. How are we going to get past them?" asked Alexis quietly.
"This looks like a job for The Chazz!" said Chazz. He went up to the guards. "Look! There's a person just waiting to be killed!"
"Where? Let's go." said one the guards. Both guards went to the 'person'.
"Okay, I have just this to say to you. What the hell, Chazz?" asked Atticus.
"What? This Supreme King likes killing people, right? Now come on, before they come back." Everyone went in the tower.
"Okay, this is such a big tower. Where is the king of this place?" asked Aster.
"I say we split up, Privates. There's only 12 of us. Let's split up in groups of 2." said Hassleberry.
"Good call, Hassleberry. Alexis, Aster, Zane, Syrus, Bastion, and I will go upstairs. Chazz, Hassleberry, Jim, Jesse, Blair, and Atticus will stay down here and watch out for fiends." said Jaden.
"Why can't I be with Lexi?" asked Chazz.
"Because I'm in charge of this little group. Let's go, guys." Jaden's group went upstairs.
(With Jaden's group)
"If I remember Jaden being the Supreme King and all, he should be up here." said Zane.
"But what if there are guards around? What if Haou is not the murderer that killed Axel?" asked Alexis.
"Please. If anyone knows a lot about death, it's the Supreme King." said Syrus.
Suddenly, Aster knocked a door down with his foot. "Aster, what are you doing?"
"I'm trying to do a sneak attack against Haou."
"I'm not deaf, you know." said a voice. The 6 kids gasped.
"Okay. Either I'm imagining things, or I could've sworn I heard a ghost."
"Oh no. I'm very much alive. And now, your fates have been sealed." Suddenly, a sword came up and tried to slice Aster in half, but failed.
"We're not here to cause any trouble! We need your help." said Jaden. Suddenly, the Supreme King came into view.
"Okay. Now I'm totally imagining things. I thought you got sent to the stars." said Aster.
"You're not imagining, Phoenix. I'm Jaden's twin brother. And I came back to Earth because I have unfinished business." said Haou. Alexis, Syrus, Aster, Bastion, and Zane all anime-fell.
"How come you didn't tell us this in the first place, Jaden?" asked Zane.
"Don't speak. You were all dead when Jaden became me. I told Jaden that he was my reincarnation, but he was also my brother."
"That doesn't make any sense. You would probably be hundreds of years old." said Alexis.
"Well, Ms. Rhodes, I apparently don't make any sense."
"How do you know all of our names?" asked Syrus.
"Jaden told me all about you people. You all are his friends, are you not?" Alexis, Aster, Syrus, Bastion, and Zane nodded. "But how did you get a separate body? If you are his reincarnation and everything."
"I have had a separate body ever since I heard about what happened in this place called Duel Academy."
"You know about Duel Academy?" said Bastion. Haou nodded.
"Wait, if you know all about that, maybe you know what happened to Axel Brodie? How he got killed?" asked Zane. Haou nodded again.
"That's great! Did you kill him?" asked Syrus.
"Syrus, that's not very nice." said Aster.
"I couldn't have killed him. I can't leave this place." said Haou.
"You have to try to leave Dark World. You have to help us find the murderer." said Yubel.
"Why the hell is she here, Jaden?"
"She's fused with me. I dueled her after she was the one responsible for this Dark World incident."
"That makes sense. Alright, I'll help you find this murderer." said Haou.
"For real?" asked Bastion.
"For real. But there's only one tiny problem. I can't leave Dark World. I haven't left this place before."
"We can help." said Alexis.
"Come on. We better get the others and get the hell out of here." said Zane.
"There are others?" asked Haou.
"Yes, 6 others." said Syrus. They went downstairs to find Chazz, Jesse, Jim, Hassleberry, Blair, and Atticus ready to go.
"You got him? Let's get out of here, then." said Jesse.
