The duel between Yusei and Sherry continues, with Akiza insisting that she stay and spectate. Yusei brings out Turbo Warrior and deals some damage, and eventually destroys her monster. However, it leaves him in a point where Sherry can win if she draws a Speed Spell, using Speed World 2's effects. Sherry then tells Yusei that she's entering the WRGP to avenge her parents who were killed by Yliaster. Just as Yusei is about to summon Stardust Dragon, Ichiro appears and tries to drop a truck on them. Akiza uses her powers to materialize Stardust Dragon and stop the truck, and Sherry's guardian, Elsworth, beats up Ichiro and his gang. Due to damage to the Duel Lanes, the duel is called off, but they promise to duel again. Akiza is left with a newfound respect for Turbo Duels.

May's Combusken manages to control the Fire Spin attack it launched. Through luck, May enters the next round with Kelly and fights Josaphine. In the final round, Kelly battles May, who has a tactic to overcome Grumpig's psychic powers. Just as Grumpig and Combusken are to fall down, May makes an honorable gesture. Meanwhile, Ash misses the contest to help his Swellow learn Aerial Ace.

The gang find a secret passageway underneath the temple and end up in a graveyard. A large group of Wandering Dooms and Wood Remains appear from the ground and begin to attack the gang. They try to fight them off but they become surrounded though and release more capsule monsters. Joey gains Flame swordsman, Téa gains Dark Witch, and Yami Yugi gains Kuriboh. They defeat the monsters and continue to their destination. They get to the fortress but walls shoot up around it along with four statues on each corner. The gang eventually figures out that they must mimic the statues in order to get inside. As Téa, Tristan, Joey and Solomon mimic the figures; Yugi goes through the open door. Yugi finds a casket covered in hieroglyphs. Rushing forward, the floor suddenly disappears from under him, causing him to fall into a big, empty room. Outside, when the gang moves from their positions, the statues come to life and they must fight them off. The walls of the empty room start closing in on Yugi and Yami. Kuribo's capsule begins to glow and Yami releases him. Kuribo shows Yami a capsule he must release. Yami Yugi and Kuribo jumped up and release the capsule, which turns out to be Dark Magician. Outside the fortress, Yami uses Dark Magician to defeat the statues and save his friends; however, Grandpa's Summoned Skull gets caught in the blast. The fortress walls fall and Yugi rushes to open the tomb, which he does just in time. The tomb reveals armor. Solomon then reads the next riddle. "Pass through this doorway and thy journey shall start, five trials will follow to test thy heart, but I warn you this journey is not for the weak, only a true warrior can unearth what you seek." The armor from the tomb is phased on to Yugi. Grandpa believes it is because the armor believes Yugi is a true warrior. Yugi and the gang pass through the doorway to the next challenge.

Leo, Luna and the others run to the school, where they greet their teacher Miss Bartlet, who tells them to try their best at Dueling 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. 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, Crow and Jack are working on their Duel Runners, 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 sends 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. 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. 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".
