Having won his Duel against Crow , Yusei and Crow begin looking for the Duel Dragon card , and are suddenly swallowed into a brilliant light . The duo find themselves in a medieval arena , dressed in Incan garb , much to Crow ' s shock , as they had been at the Fourth Duel Zodiac . He then takes note of what they are wearing . Yusei wonders what ' s going on here , and then a voice asks if it is they who seek a Duel Dragon ceremony . Crow asks the figure , who rides out on horseback , who he is . The man , who ' s eyes are hidden by a hood , declares that he is the one who opens the door for those who seek Duel Dragons . Crow asks if that means that he ' s the door guy , and expresses disbelief . He asks what the man is , and where they are , commenting that the whole thing is way past insane . The man explains that this is ceremonial ground ; a place where one may gain a Duel Dragon . Yusei remembers that Goodwin told him that Turbo Duel s were originally conducted as ceremonies to oppose and seal away darkness - and that Duel Dragon cards hold the power of the dragons controlled by the priests in those ceremonies . Yusei realizes what this means if what Goodwin said was true , and the Priest explains that many warriors have attempted the ceremony , and fell into darkness , their souls shattered . If Yusei is prepared to plunge into darkness and let the Duel Dragon make a living corpse of him , he should advance . The form of the Duel Dragon appears during this description - the same one that appeared behind Yusei when he vowed to subdue one . Yusei remembers Sect ' s words when he recieved " Beelze " . He thinks that he needs the power of a Duel Dragon if he ' s going to oppose " Beelze " and save Sect . Yusei steps forward . Crow asks if he trusts the Priest - he could be anybody or anything . Yusei simply states that if it will lead him to a Duel Dragon , he ' ll go forward . He ' ll use his power to bring the Duel Dragon to its knees . The Priest murmurs " force it to its knees ? " and adds " very well . " The two Duelists mount horses , and face - off with stone tablets surrounding the arena , and one behind each duelist , Yusei ' s " Lightning Warrior " , and the Priest ' s Duel Dragon . Crow realizes that it ' s a One Shot Run , using horses instead of Duel Runner s , and stone wonders if he ' s dreaming , or went insane after losing to Yusei . The Priest states that Yusei ' s " monstaba " , his monster , is " Liu Akwek , " the " Lightning Warrior " . Yusei tells his monster to come forth , and " Lightning Warrior " emerges from the tablet , with a more medieval appearance . The Priest tells his monster to " descend from the starry heights to their terrestrial plane , " and both Crow and Yusei feels the enormous power of the Duel Dragon . " Stardust Spark Dragon " erupts out of the ground behind the Priest , and his horse rears up . Yusei thinks that that power will be his with an uncharacteristic smile . The Priest tells Yusei that he ' s coming , and both combatants start moving , yelling " Duel ! " While they run , the Duel Dragon ' s Shadow miasma surges towards Yusei , prompting Crow to comment that it ' s like darkness incarnate . " So what ? " Yusei comments . This will all be his , the stronger the better . The Priest is impressed that Yusei has opposed the flow of the miasma . But how long will Yusei last before falling back ? Yusei only states that he needs power , and Crow realizes that something ' s wrong . Yusei cries that he ' ll use his most powerful Sense to win the ultimate power , yelling for more , and ordering his horse to go faster . The Priest observes that Yusei has fallen in darkness as well . Yusei orders his horse to run faster . At that time , Yusei remembers his One Shot Run against Akiza , and how she told him the if all he did was increase his speed like a maniac , he ' d never beat Jack Atlas . Realizing what he ' s done , he pulls up short , and the darkness surrounds him as " Stardust " gets closer . Suddenly he ' s struck be the the same sensation that showing him Leo ' s memories , and sees several opponents facing off against " Stardust " , all trying to obtain its power ( and obviously failing ) . He realizes that he ' s in the memories of " Stardust " itself , and sees the Duel Dragon , now all white as opposed to the dark - coloured beast he ' s fighting , hovering in front of him . " Stardust " roars and Yusei wonders if the dragon is crying . Returning to reality , he begins to slow down his horse , much to Crow ' s shock . Yusei simply states that he remembers Akiza , and once again remembers what she told him . Then he remembers his Duel s against Jack , who told him that friends were a lie , an excuse for weaklings to cling together , and suggesting Yusei lose the " shackle " and he might Duel a bit better . He remembers Crow ' s vow to become Trubo Duel Emperor , and his match against Leo and Luna , where Leo had yelled at him for hurting Luna . Yusei then stops , and " Lightning Warrior " vanishes as he states that Dueling his rivals made him see it again . Crow realizes that Yusei ' s going to take a Direct attack from the Duel Dragon , and cries his friend ' s name . Yusei tells " Stardust , " who looms over him as the Priest rides past Yusei , that he ' ll accept it all . The thirst of all those who wanted him , and his sorrow , and finally remembers his friend Sect , asking " Stardust " to let him laugh with his friend again as they Duel . Spreading his arms , he begs " Stardust " to lend him his power , and give him the strength to save his friend . Crow yells Yusei ' s name , and the Priest gallops past Yusei . Yusei looks at " Stardust , " who has begun to turn white , the last vestiges of darkness vanishing from the Duel Dragon as its maw closes over Yusei with an explosion of light . Featured cards .
