Arriving back at the Stadium , he throws it to Tori , who is midway down the stairs . She runs down and yells to Yuma , but trips and lands in the Duel Coaster on Yuma ' s lap , with the Heart Piece falling directly into the activation panel . The coaster immediately buckles them in and begins moving , so Tori can ' t get off . Yuma says the two of them have to fight together now and Astral reminds him its three . Heartland says this is an interesting development . Yuma ' s coaster didn ' t start right away and now he has a passenger . He says each coaster should have only one person in it , but says he ' ll allow it anyway . Yuma yells that he loves this concept and Tori tells him to slow down . He says he can ' t - he ' ll never catch up to the other finalists if he does . However he doesn ' t how to Duel like this , even if he locates an opponent . Astral tells him to look around - there can be more than one coaster on each track . They can see Nistro coming up behind another finalist . He yells for the man to move and says he ' ll defeat anyone that ' s in his way . He draws and Normal Summon s " Heroic Challenger - Spartan " , who appears above him . He sees his opponent has " Battlestorm " out and says that ' s good for him . He activate s " Riryoku " , halving the ATK of " Battlestorm " and adding it to that of " Spartan " . He orders " Spartan " to attack and destroy " Battlestorm " with " Straight Javelin " . The finalist , who is dressed like a cowboy , yells " unbelievable " as his Life Points drop from 1300 to 0 . The seat of his coaster launches him upwards and the track bends downwards to allow the now - empty cart to leave the track . A parachute engages and the Duelist floats towards the ground . Astral says a single mistake could mean the end for them here . Astral says he understands - you can Duel someone who is the same lane as you and Yuma adds that you can switch lanes at will . In another lane , Shark has " Jawsman " out , while his opponent has " Master of the Flaming Dragonswords " . He orders " Jawsman " to attack with " Shark Scream " . His opponent ' s Life Points drop from 800 to 0 . From the stands , Bronk says that ' s expected of Shark and Cathy asks where Yuma is . Shark sees Quattro in an adjacent lane and Quattro taunts him , saying he ' s sure showing off a lot . Quattro speeds off and Shark yells he won ' t let Quattro escape , claiming he ' ll break him in this fight . Quattro Summons " Gimmick Puppet Egg Head " and attacks his opponent directly , dropping him from 1400 Life Points to 0 . Quattro laughs and says that the trash should get off the track . Quinton is nearby and muses that Quattro is acting full of himself as always . He says he doesn ' t seem to realize how long of a fight awaits him . Quinton says fighting shouldn ' t be the main goal right now - protecting and increasing your Life Points should be . Quinton checks the map and sees a Spell Point ahead as an opponent approaches from behind , who controls " Vylon Disigma " . The Duelist says he ' s in the way and orders " Disigma " to attack directly . Quinton stands up in his coaster and says that anyone who approaches him will be burned with hellfire . He activates his face - down " Infernal Sun " and explains that when an opponent attacks directly with a monster that has 2000 or more ATK , this card will inflict 800 damage for each card in the opponent ' s hand . The opponent has five cards , which disappear in streams of light , which wrap themselves around a black sphere , which hits the opponent for 4000 damage , defeating him . Quinton passes the Spell Point , which activates . It is " Dian Keto the Cure Master " , so he gains 1000 Life Points , giving him 5000 total . Vetrix passes in the next lane over , saying that was expected of Quinton . He says Quattro and Shark aren ' t holding back and wonders how Yuma is doing . Yuma is excited to watch all these Duels , but wants to Duel himself . Astral says he ' ll get his wish right now and says to look in front . Yuma sees two Duelists in the lane to his left and one in the lane to his right . He says he just passed them . Wolf says that thanks to Yuma being late , cornering him became much easier . Jackal says they just have to defeat him now and Coyote says the big money will be theirs . Vetrix is nearby and says they are right - they ' ll be given as much money as they wish - if they can show him Yuma ' s true power . Wolf says they ' ll begin as planned with formation one . Jackal and Coyote respond with " Roger ! " . Wolfsbane changes lanes and is now behind Yuma . Tori sees him first and warns Yuma . Astral says they must have been waiting . Yuma is confused and Astral says they stayed in adjacent lanes so that Yuma can ' t escape . No matter which lane he ' s in , one of them will be able to attack him . Wolf rams him from behind and Yuma curses , saying he ' ll escape . Yuma speeds up and Tori screams as the coaster track goes downwards . Astral sees a Trap Point on the map , marked with " Caution ! " . The card activates . Its " Secret Barrel " , which drops Yuma ' s Life Points to 3000 - 200 damage for each card in his hand and on his field . Yuma says there must be Spell and Trap Cards Set all around the field . Jackal says Yuma didn ' t notice the Trap Point and Coyote wonders if his Dueling is really that poor . Wolf tells them they ' ll finish him off quickly and get their reward . Wolfsbane communicates with Yuma via the coaster monitors and says they ' re going to Duel now . Wolfsbane says formation two and Jackal and Coyote respond with " Roger ! " again . Wolfsbane Normal Summons " Magnet Eagle Delta " , while Jackal and Coyote both Normal Summon " Magnet Saucer " .
