By the order of the cheif of the detention center, Takasu, the 2 securities take Yusei to meet him privately in a room. In the main hall where Yusei and Yagani dueled Himuro, many prisoners gather up there. Yanagi now hangs around with Himuro and his gang, which have become his good friends by now. He is looking at his treasured cards, checking them, and keeping them back to his cloth.
Himuro then asks Yanagi whether Yusei was arrested because of trespassing (from Satellite to Neo Domino City without permission). Yanagi confirms that Yusei is, and so is he. Himuro thinks that this is strange. The securities should check Yusei already before he had come here. Yanagi was also arrested by the same reason and even about the same time last night, but Yusei is the only one called for a private investigation. Himuro doesn't understand what the warden, Takasu, really wants to investigate Yusei. As far as he knows, Takasu is a very tough guy. This makes him have bad feeling about this investigation.
Yusei is brought into a lab. There are 2 researchers in a white coat, the 2 securities currently controlling Yusei, and Takasu standing in front of him. Takasu first greets Yusei by acting rudely to him. He takes some hairs from his nose, blow them in front of Yusei, and makes it clear to him that he really hates people from Satellite. Takasu then moves behind Yusei and catches his arm to his back. Although he doesn't want to touch Satellite people, he needs to investigate Yusei now.
Takasu checks Yusei's right arm and doesn't see any single mark. The dragon mark that appeared in the duel with Jack (episode 5) has already gone. Takasu rudely pushes Yusei to the 2 researchers, telling them to investigate thoroughly. Yusei turns back and stares at Takasu with angry eyes.

In the lab, Yusei is put into a physical examination. His cloth is taken off and remains only a short pant. His body is then placed into a scanner machine. A researcher then starts the scanning process, launching electricity running through Yusei's entire body. Yusei screams and struggles in pain. Takasu is standing behind the researcher and waiting for the result. Yusei keeps crying loudly as the electricity is running through.
When the scanning is done, Yusei seems to lose his mind. His eyes look blank as same as his sense. Takasu catches his hair to pull his head up. He wonders whether Yusei has been enough already. Yusei gains back his sense and stares at Takasu angrily. Takasu tells him that his D-Wheel and deck don't deserve to belong to a Satellite guy like him. Thus, the public security maintenance bureau will take them all.
Also, the director, Rex Godwin, seems interested in those stuffs, so he may be investigating them thoroughly in the security warehouse. As saying Takasu, takes some pieces of hair from his nose and blows them in front of Yusei again. Yusei looks clearly very angry after hearing what's going to happen to his properties and also what Takasu is doing to him.

At the building of the public security maintenance bureau, Jaeger is walking after Rex in a hall way and entering Rex's office. He tells Rex that Yusei's information at the detention center has just been transferred to here. When Rex is ready on his seat, Jaeger begins to open his virtual controller and displays that information on screen. According to the result of the investigation from the warden, Takasu, there has been no trace as an indication of a Signer found on this Satellite man by now. However, Takasu informs that he will keep inspecting him. Rex nods his head as he has understood.
Jaeger, by the way, asks whether Rex has told the King, Jack, everything. Rex is afraid that he didn't. If he had told the King everything, he wouldn't have been able to suppress his anger. Jaeger chuckles and thinks that this should be more interesting. After finishing with Jack, Rex thinks that he next should try to go and meet the Satellite guy or Yusei at the detention center.
At the detention center, the securities take the weak body of Yusei back to his cell. One of them throws him into his room, and Yusei seems knocked out without movement. Yanagi sharing his cell with Yusei steps down from his bed and asks whether Yusei is fine. He tells him to hang up while Yusei is trying to hold himself up and sitting near Yanagi. Yanagi asks Yusei directly what the securities did to him. Yusei replies that they just want to look for a mark on his body. Yanagi is surprised by what mark Yusei is talking about. Yusei clarifies that the mark appeared on his arm when the crimson dragon appeared, and it then disappeared.

Yanagi isn't sure and is about to ask Yusei further. However, he quickly closes his mouth once he hears a security walking pass his cell. It's discussion that he doesn't want anybody to hear. When Yanagi is sure that the security has already passed the room, he asks Yusei directly whether he is a Signer. Yusei looks confused as he has never heard about it. Yanagi tells him that when he traveled around South America, he heard the legend of people of the stars. Singer is a word coming from that legend. In the legend of the people of the starts, the crimson dragon is a god and they call a person with a dragon's mark a Signer.
There are 5 Signers, and each individual has a dragon. They all have 5 dragons in total to release the power of the crimson dragon. Yusei thinks about Red Demon's Dragon and Stardust Dragon that appeared in the mid of his duel with Jack. They are 2 of the 5 dragons Yanagi is talking about. Yanagi tells Yusei that the form of the 5 dragons have been changing over time, but they are living. To think about it, he doubts whether Yusei really has one of those 5 dragons.
Yusei thinks about what has happened and realizes that everything makes sense now to his Stardust Dragon. Yanagi is getting very excited to hear that the dragon is now in a form of a card. He tries to ask Yusei that he really wants to see it. Yusei is afraid that he doesn't have it now. Yanagi is pity that he would like to see it very much. Anyway, he thinks that it's strange as he doesn't understand why the securities at the detention center are interested in this stuff. Yanagi's words make Yusei doubt about it as well.

Jack is currently sitting in his dark room. He opens the top card on his deck, and it appears to be Red Demon's Dragon. Jack doesn't look in a good mood and keeps thinking about what Rex told him that he's a chosen person of the stars. Mikage then enters the room, and Jack asks what she wants. She reports that she has just got the details about a challenger for Jack's tomorrow duel, so she would like him to look through it. Jack changes the topic by asking how he looks to her now. Mikage replies that Jack is certainly a king of duelists.
This question makes Jack very angry. He quickly gets up and says that his undefeatable record has already been over. He has already been defeated by Yusei, so he is no longer a king. Jack yells at Mikage as throwing Red Demon's Dragon card aggressively onto the table. Mikage disagrees and thinks that Jack deserves to be a king. Jack gets more angry and says that he can't be expected to duel with that kind of notion.
Seeing Jack's act, Mikage can't say anything. Jack moves to the window and looks up to the moon. He doubts that he is looking like a clown. Meanwhile in the cell at the detention center, Yanagi is sleeping and snoring loudly. Nevertheless, Yusei can't sleep, still stays awake, and looks at his arm where the dragon's mark used to appear.
In the next morning, all prisoners are together in the main hall as Rex is standing on the front stage. Tataku tells the prisoners that the director, Rex Godwin from the public security maintenance bureau of Neo Domino City is invited here today for the education program. The director is going to give a speech, so he hopes everything will listen carefully. Rex's eyes then move straight to Yusei as a target. Yusei can be aware that he is watched over. Even Yanagi and Himuro can notice that.

At the duel stadium full of audiences, a duel king match is about to start. The host is announcing the time for the main event today and welcoming a challenger to the king, Jack Atlas. This challenger has given a challenge to the king for a revenge. At the same time, Jack is preparing himself in his resting room. Mikage is standing behind, mentioning that Jack in the current form fits him very much and that she is glad for Jack to accept today duel.
Jack looks in a very bad mood as crossing his eyes to Mikage. Mikage can feel his anger, so she says no more. Jack asks whether the director, Rex, is watching today. Mikage is afraid to tell the truth that the director is going to the detention center today. Jack can easily understand Rex's purpose to go there but doesn't say anything. He then picks his deck and stands up for the coming duel.
At the duel stadium, the host is announcing the coming back of the flame revenger, Enjo Mukuro. Mukuro appears with his Bike D-Wheel from the exit full of smoke. He declares that he is going to beat the king down today by his strongest and best deck. The next king is going to be him. Mukuro breaks his D-Wheel and stands by for his opponent to appear.
On the other side, Jack is preparing himself while setting up his deck into his D-Wheel. He turns on his engine as his eyes look very serious. The host at the stadium then announces the appearance of the king of duelists, Jack Atlas. Jack with his white D-Wheel jumps out from another entrance full of smoke. As usual, he introduces himself to the audiences, "There is only one king, and that's me!".

The host describes that the challenger, Mukuro, looks much different today, suggesting people watch over him carefully for his newly recreated deck since the last duel against the king. It's interesting how the king is going to deal with it. Jack is currently moving his D-Wheel to the starting position behind Mukuro waiting for him there (A challenger is normally in the front position while the king is behind to let the challenger go first). He thinks that the duel of a king is what he has looked for. Jack looks around to see the large audiences and cheerleaders in the stadium. Everything is calling his name. As Jack is on this stage, people cheer and motion have never been empty.
The host mentions whether people are going to witness birth of a new king today. Meanwhile, Mikage is entering the stadium and watching the game from an audience area. She is looking worried about Jack. It's about time to duel, so the host declares both duelists to set up their Speed World. This field spell is set up into both Jack's and Mukuro's D-Wheels, creating the speed duel theme around the stadium. The computers on both D-Wheels say, "Duel Mode on, Auto Pilot, Standby!".
A time counter appears to give a starting point. The host declares that the match of the century is going to begin and it's interesting who is going to win. Time has come, and the signal turns green for a start. "Riding Duel, Acceleration!", the host declares while the game begins. When the game starts, Jack accelerates his D-Wheel to lead Mukuro. The host declares the first turn coming to the king.

1st Turn - Jack
Drawing a card, Jack summons monster [Dark Resonator - 3/1300/300: Once per turn, this
card cannot be destroyed in battle] onto the field in defense position. The host introduces this monster to the audiences and describes that it can't be destroyed in battle once per turn. Mukuro realizes that Jack is playing a tuner monster. Setting 2 face-down cards, Jack ends his turn. The host doubts and describes whether these two cards are going to create a major highlight today.
At the detention center, Rex is giving a speech to the prisoners, saying that there is a great meaning for him to sort people of both Neo Domino City and Satellite. The two worlds are complementary and develop one another. There are necessity and reason for people who reside in Satellite as Satellite residents and people who live in Neo Domino City as Neo Domino City residents. At the same time, Rex is stepping down from the stage and walking into the prisoner lines. Some of them begin to yawn as listening to Rex's speech. When they see Rex walking in, they turn back to pay attention.
Rex stops in the middle of the prisoner lines close to Yusei's position. He continues his speech that leaving Satellite is going to throw the world into disorder. A reckless action of a person can cause a trouble for his friends, following by pain. While saying, Rex is looking towards Yusei , who is staring Rex back with serious eyes.
