Summary . The Facility . Two of the Facility officers lead Yusei to an interrogation chamber . Tanner notes that since Yusei was sent to the center for trespassing , they would have investigated him before sending him there and wonders what more could they be looking into . Knowing the chief Mr . Armstrong , Tanner has a bad feeling about this . Meanwhile Mr . Armstrong checks Yusei ' s arm where the dragon mark appeared during his duel with Jack . The mark was not present , so Armstrong shoves Yusei over to the other officers commanding them to search him thoroughly . Yusei is stripped down to his underwear , strapped to a table and put inside a machine . Inside it , he is subjected to a number of shocks before being brought back out . Armstrong grabs Yusei by the hair , asking him if he has had enough and tells him things like a Duel Runner or a Deck are not to be wasted on residents of Satellite . He tells Yusei that the Director probably has the Securities searching Yusei ' s Deck and Duel Runner . At the Security Headquarters , Lazar shows Rex Goodwin , that the Facility has so far found no trace of anything regarding Signers on Yusei . Lazar then asks Rex , if he has told Jack about everything yet . Goodwin says that he had to tell him everything to subdue Jack ' s anger . Lazar finds this is where things shall get entertaining . Goodwin agrees and says that he must next meet Yusei . Back at the center , Yusei is thrown back into his cell with Yanagi . He briefs Yanagi in on how they searched for his dragon birthmark . Yanagi , who was unaware Yusei had such a mark , asks him if he ' s a Signer and tells him what he ' d heard about the People of the Stars , when he was in South America ; According to the People of the Stars ' legend the Crimson Dragon was God , and people with dragon birthmarks , capable of calling out the dragon are called Signers . There are five signers , each with their own dragon . The five dragons have changed their looks over the ages , but still live on . Yanagi pauses for a second , realizing something . He quickly jolts his head closer to Yusei , asking if he has a dragon . Yusei calmly says that if that ' s what that card is , that would make sense . Yanagi gets excited and asks if he can see the card . Yanagi ponders as to why the people at the center at interested in that . The next day at the center , Armstrong introduces Goodwin , before Goodwin gives a speech to the inmates on Security . Goodwin catches a glimpse of Yusei in the crowd . He explains the significance of why he has split people into living in New Domino City and Satellite . As he does so , he walks into the crowd stopping next to Yusei and saying crossing from Satellite to New Domino can throw the world into disorder . Someone doing so can cause trouble to their friends . After the speech , Armstrong orders everyone back to their cells , but tells Yusei to stay . Rex tells Yusei that Jack is dueling around now and asks about his birthmark . Yusei asks Goodwin what he is scheming and demands that he leave his friends out of this . Jack . At Jack ' s mansion , Mina has information on Jack ' s challenger for tomorrow . She would appreciate it if Jack would look through it . Jack doesn ' t seem to care too much about the data and asks Mina how does he look . " Unquestionable , like the King of Du . . . " she replies before Jack interrupts her declaring that he isn ' t . He lost his undefeated record . He is no King . Mina disagrees saying that he should be King . Jack is insulted by the words " should be " . He walks over the window and asks if this mean that he ' s " the clown " ? At Jack ' s Riding Duel , he finds the crowds cheering and emotions have no effect on him . On Hunter ' s first turn he lowers Jack ' s LP to 1000 and reveals how he plans to finish the duel next turn , making him King . Jack mocks Hunter ' s dueling and calls it luck .
