Rudolph Heitmann , the head instructor of the Duel Academy , wants to expel Leo and Luna ' s class , stating that they are low level Duelist s because they use low level monsters , so they are not necessary there . Yusei Fudo visits the Duel Academy , where he hears Heitmann ' s plans . He Duel s against Heitmann , stating that no person and no things are unnecessary in this world . Summary . At Duel Academy . Leo , Luna and the others run to the school , where they greet their teacher Miss Bartlet , who tells them to try their best at Duel ing today . Akiza Izinski comes running up saying hello to Leo and Luna . Luna says that she heard that Akiza was at the top of her class again . Leo thinks that it is amazing and it empowers him to try to be at the top of his class too . The Duel lesson of the day was on Warrior - Type monsters and the featured Duel was between Leo and Dexter . After the Duel , Luna mentions the fact that Leo was aiming to be at the top of their class , Leo then draws the next card to see that it was " Marauding Captain " to which he states that if that card had came earlier he would ' ve been able to Synchro Summon " Power Tool Dragon " . Their teacher Miss Bartlet , pointed out that he wouldn ' t have been able to Summon his favorite card ( " Power Tool Dragon " ) because it was a lesson on Warrior - Types and " Power Tool Dragon " isn ' t a Warrior ( " Power Tool Dragon " is a Machine - Type ) . Leo responds saying that he would be stronger if he could make a Machine - Type Deck , to which Bob challenges Leo to a Duel with Patty facing Leo afterward . This causes Leo to believe that he is popular , only for Bob to mention that if they were to duel Leo , that he and Patty would win for sure . Heitmann watches the Duel and laughs , saying that they should laugh while they can . After School . Bob , Patty and Dexter all ask if they are going to Yusei ' s place together as well , to which Leo says yes , they all are going . Luna is unsure and asks if going to Yusei ' s place everyday to play is bad . Leo responds that it is fine . They see their fellow classmate Sly walk past them . Luna asks if he is heading home alone and invites him to hang with them . Sly first says no , but overhears Patty say that she is excited to meet Yusei . Sly then ponders and decides to follow them to Yusei ' s place . Yusei ' s Place . Yusei , Crow and Jack are working on their Duel Runner s , with Jack testing the Runner again pushing it as before , getting it up to 90 % . At this point Crow asks if this is really okay , because he doesn ' t want an explosion like last time . Jack displays his concern about it blowing up , since he is on it again . Yusei says there ' s no problem with the engine , which implies the problem lies in something else . Suddenly the Deck releases all the cards stored in it and send s Yusei ' s Deck flying out everywhere as smoke comes from the bottom of the Runner . Zora comes in and shouts at them for the noise and mentions that she doesn ' t know why she lets them stay there . Crow and Jack take responsibility , telling her not to blame Yusei . However Zora mentions that she was referring to Jack and Crow from the beginning . She yells at them to not hold Yusei back and cooperate with him as she leaves . Crow begins to make fun of Zora , but Yusei stops him and tells them to be glad that she even lets them stay there , Crow agrees and says that they will have to do something about the cards that flew around . Luna , Leo and the others come into the basement . They see the mess and Luna asks if there was another explosion . Crow replies that there was an error in the machine . Bob , Patty and Dexter are amazed by the Duel Runner . Crow tells them that they use the frame for testing . Jack yells at the children that they shouldn ' t touch things without permission . Bob asks if they can play and Patty says please . Jack says no but Crow overrules him by saying that they can play , but only if they help pick up the cards , causing Jack to yell at Crow . All of them except for Jack ( who is on the Test Runner ) and Yusei ( who is on the computer ) began to pick the cards up . Sly arrives as they do so . Yusei notices Sly first , followed by Leo , who asks why he is there . Sly starts to leave , but Luna pulls him back in and down the stairs . She introduces him to Yusei . Sly points out that Yusei doesn ' t look as cool as he thought he would . Crow snaps and tells them to get back to picking up the cards . Sly isn ' t pleased that he must help pick them up too , but then he comes across " Stardust Dragon " . Yusei approaches Sly , saying that it should be there somewhere , prompting Sly to give the card back to Yusei , much to his own disappointment . The Next Day . Yusei is shown working on the frame of the Runner , before a man comes in and informs him of a mechanical problem that he has at Duel Academy . The " mechanical problem " is named Heitmann . The Academy . Heitmann yells at Leo and the rest of the class to be quiet and that no matter what they say , his decision to kick them out is final . Bob and Patty ask why are they all being expelled , to which Heitmann replies that they all have low grades and are undeserving . This is New Domino City ' s best Duel Academy , and as such , they are going to change to a more " Higher - Leveled Class " . Miss Bartlet states that what he is doing is wrong , all children have the right to duel , which that the principal has always said so , but Heitmann cuts her off saying that she might be surprised that this is also the principal ' s decision , much to Ms . Bartlet ' s surprise . Heitmann finishes saying that the stubborn Principal is listening to what he has to say . Luna begs to not expel them and Leo adds that they are just now beginning to do their best , Heitmann responds that they are in no position to say that , especially Leo who happens to be at the very bottom of their class . Akiza then enters to add her thoughts . Heitmann says " You ' re Akiza " as she enters . Akiza asks how can he be like that and still be proud to be a professor , to which Heitmann responds that a superior student like herself would understand what he has to say . She doesn ' t and won ' t forgive any person who hurts children . Leo worries about Akiza ' s powers and mentions that he ' s afraid of what would happen if Heitmann got Akiza too upset . Yusei enters and asks Akiza if everything is okay . Heitmann asks if he is Yusei who won the Fortune Cup , which causes the class to cheer in excitement . Heitmann asks Yusei what brings him to their Duel Academy . Yusei says that he is there to complete a job and that there is something in the classroom that needs fixing . Heitmann argues that nothing in the room needs to be fixed , because the students are beyond fixing . Akiza scolds him over and asks him if he thinks judging people based on grades alone , and stopping Duels are a foolish thing . Heitmann retorts saying that she is the one who is foolish and that no matter how a low - leveled duelist duels , it is pointless and points out that every key card in the following duelists ' Deck s are trash : Leo ' s " Morphtronic Remoten " , Luna ' s " Kuribon " , Dexter ' s " Batteryman AA " , Bob ' s " Flamvell Guard " , Patty ' s " Hanewata " and Sly ' s " Eccentric Boy " , saying that because their Duel Level is low , isn ' t that why they are using low level monsters . Yusei says that he ' s wrong and that there is nothing useless in this world . Heitmann says that he is an outsider and that an outsider has no right to interfere on this and should just go home . Heitmann then asks Yusei again as to why exactly he is here . Yusei answers that he is there to fix something called Heitmann and that they say that if the screw is tightened just a bit , it should be fine . Heitmann interrupts to point out that that is him ; Rudolph Heitmann , much to Yusei ' s shock . The class then asks Yusei to help them because they will be expelled . Yusei challenges Heitmann to a Duel ; if Yusei wins the expulsion is waived and Heitmann accepts , saying that an outsider has no right to duel . Break Before The Duel . Yusei is with the children on the brink of expulsion . Miss Bartlet expresses her concerns for Yusei to Akiza , because Heitmann ' s Deck is strong . Akiza tells her not to worry , if they leave it to Yusei , he will win . The group of kids all wish Yusei luck , but Yusei asks them for a favor , confusing them . The Duel then begins . Later on during the Duel , it is shown via flashback that the " favor " Yusei asked them was to borrow the monsters that Heitmann called useless so that he could teach Heitmann that they and their cards are not useless . After The Duel . Yusei tells Heitmann that there are children who duel seriously and that it doesn ' t matter about the Level of the monster s used . The man who informed Yusei of the problem earlier enters and tells Yusei that that was he expected of him ; he tightened the screw like he asked . Yusei realized that it was the principal who had came to see him earlier . The principal apologizes to Yusei for tricking him , but he wasn ' t able to persuade the stubborn Heitmann himself . Heitmann asks the principal if he asked Yusei to defeat him , to which the Principal asks Heitmann how was it . Heitmann replies that he was wrong . The children come running and hug Yusei cheering that he won and that they get to stay , after which Heitmann announces that he withdraws his expulsion request . As the Principal leaves , Zora shows up . The principal tells her that there was no mistake in her decision . Zora tells him that , that Yusei has an interesting power ; he can even ignite people ' s hearts . Yusei walks over and thanks Sly , handing back the card he borrowed , saying that he couldn ' t have won without it . Sly simply replies " yeah " and takes the card back . Yusei and the other children turn to exit , leaving Sly to think to himself that he must obtain " Stardust Dragon " . Featured Duels . Leo vs . Dexter . Duel already in progress .
