Kay Set s a card and ends his turn . " Gogogo Golem " then returns to Yuma ' s side of the field . Yuma is surprised because he didn ' t expect Mr . Kay to use his monster s . At that moment , a warning is heard alerting them that in twenty minutes the virus bomb will be released . Astral begins his turn and Yuma reminds him again that it ' s his turn . Caswell Francis comments that Yuma has been talking to himself the whole time and asks Tori if he ' s okay . Tori tells him that he ' s fine and that it ' s just his " Bring it to ' em " mode . Yuma begins his turn and draws a card . Astral tells Yuma to Summon " Ganbara Knight " but Yuma warns Astral not to butt into his problem . However , Astral reminds him that a " Number " monster is riding on the Duel and that , if they don ' t get it , Astral will be obliterated . Yuma just says he doesn ' t give a care about him . Then , Astral says Yuma isn ' t strong enough to win on his own , which makes Yuma extremely angry at Astral . Yuma says he ' ll no longer do a single thing Astral tells him to . Astral doesn ' t understand exactly what Yuma means by not doing anything he tells him and Yuma explains that , if Astral tells him to move his right hand , he ' ll just move his left hand . After that , since Astral chose " Ganbara Knight " , Yuma Normal Summon s " Achacha Archer " , which leaves Astral baffled . Through its effect , Mr . Kay takes 500 points of damage . Yuma is happy since he delivered damage but Astral says that doing that came with a huge price . Astral explains that , if Yuma had Summoned " Ganbara Knight " , he would have had two Level 4 monsters and , therefore , could have done an Xyz Summon to bring out " " . Yuma realizes he messed up but tries to cover it up by saying he already knew that . Mr . Kay activates his Trap Card , " Damage Vaccine Ω MAX " , recovering the damage he took . Mr . Kay then says he yearns for a perfect victory and won ' t let Yuma injure even a speck of his LP . Caswell starts to panic , saying that even if he was used , he was still the one who launched the virus bomb and that , to summarize , he ' ll be blamed as the culprit . Tori looks at the clock , showing seventeen minutes and thirty seconds left and says they ' re running out of time . Kari continues to search for the switch for the virus bomb in the labyrinth and swears she ' ll stop the bomb . Back at the Duel , Yuma ends his turn . Mr . Kay begins his turn and activate s the effect of " " , detach ing an Overlay Unit to gain control of " Gogogo Golem " . Astral says that , if Yuma had Summoned " Utopia " , Mr . Kay would have nothing to steal because " Terror - Byte " can only control monsters with Levels and Xyz Monster s don ' t have Levels , but rather Ranks . Astral then tells Yuma his Duel is defective and that he would be better off just obeying him , to which Yuma just tells him to shut up . Yuma says , although he ' ll take damage , in his next turn , " Gogogo Golem " will return to his field and he can then Summon " Utopia " . Mr . Kay just laughs and says he ' s not a foolish Duelist who uses the exact same strategy he used the previous turn . Mr . Kay activates two Continuous Spell Card s , " Infected Mail " and " Cracking " . Tori asks Caswell what exactly are Continuous Spells and he says that , unlike Normal Spell Card s , Continuous Spells , as long as they remain on the field , will always have their effects active . Mr . Kay explains that , through " Infected Mail " , he can choose a Level 4 or lower monster and attack the opponent directly with it but , after that , the monster is destroy ed . Mr . Kay attacks Yuma with " Gogogo Golem " through " Infected Mail " . After the battle , " Gogogo Golem " is destroyed and Mr . Kay activates the effect of " Cracking " , inflicting an extra 800 points of damage to Yuma . Mr . Kay calls this technique the " Terror - Byte " combo and Yuma comments that that combo is going to give him some problems . Yuma sees Astral fading a bit and Astral explains that , when his LP are depleted , so will his own life . Yuma remembers the time when Astral warned Yuma that , if he loses , he ' ll lose something of great value . Tori wonders what ' s wrong with Yuma since he seems a bit down and Caswell praises him to cheer him up , calling him an unrecognized genius and telling him that , if he unlocks the dormant talent within him , he ' ll definitely win . Yuma is pleased at hearing this and says he ' ll do his best . Astral says his Observation nº 6 : " Humans work their hardest when they are praised . " and tries to do it himself . Astral talks about Yuma ' s " eternal combo of recovery " , the way he jumps over boxes , drowns in the pool and how he changes his character at whim ; and that , summarizing it , he ' s quite intriguing . However , Yuma doesn ' t like hearing this and angrily asks Astral if he ' s looking for a fight . At that moment , the room they are in starts to shake and moving upwards . Kari finds the final door where the switch is and finds out that , to stop the virus bomb , she needs to defeat a Crashbug Avatar inside . Kari accepts this challenge and sends her own avatar to a karate fight . Back in the tower , Mr . Kay says that the place they ' re in will be the front row seats to watch the virus bomb ' s success . Mr . Kay Sets a card and ends his turn . Astral thinks to himself that Yuma is bound to lose to him but that he must win at all costs . Astral then recalls what Yuma said about not doing anything he ' ll say and sees it as an approach . Yuma begins his turn and draws " Goblindbergh " . Yuma Summons it and , with its effect , he ' s allowed to Special Summon a Level 4 or lower monster from his hand . Astral tells Yuma to Summon " Zubaba Knight " but Yuma refuses and Summons " Ganbara Knight " instead . Realising he has two Level 4 monsters on the field , Yuma overlays " Ganbara Knight " and " Goblindbergh " and Xyz Summons " Number 39 : Utopia " . Astral tells Yuma not to set the Trap Card in his hand , but as Astral predicted , Yuma does so anyway and ends his turn . Kari has just left the Crashbug Avatar with 50 LP whereas Kari has 1000 left . She thinks the battle is won but Crashbug can still rise . Mr . Kay begins his turn and draws a card . He activates the effect of " Terror - Byte " again , gaining control of " Achacha Archer " . Then , through the effect of " Infected Mail " , he can use " Achacha Archer " to attack Yuma directly . Yuma panics , thinking there ' s nothing he can do , but Astral reminds Yuma that " Utopia " has a great effect of his own . Yuma activates the effect and sends the overlaid " Ganbara Knight " to the Graveyard to negate an attack . Astral explains that Yuma is safe because , since " Achacha Archer " didn ' t attack directly , he isn ' t destroyed and , therefore , " Cracking " won ' t activate . Also , Astral points out to Yuma that Mr . Kay has used up all of the Overlay Units that " Terror - Byte " had , so its effect can no longer be activated . Mr . Kay comments that he thought Yuma was just dumb but apparently isn ' t and Caswell also says that Yuma seems much smarter than usual . Tori wonders if it ' s because of the Dueling Spirit Yuma sees . Mr . Kay tells Yuma not to think he didn ' t read through that strategy . He also adds that the conditions for his perfect victory have been set . Mr . Kay activates the Trap Card , " Bug Switch " , switching a monster from Defense Position to Attack Position and , since " Crashbug X " , " Crashbug Y " and " Crashbug Z " are in the Graveyard , he can Special Summon " Super Crashbug " in Defense Position . Yuma is relieved because he thought it would be in attack . However , through the effect of " Super Crashbug " ' , all Attack Position monsters have their ATK and DEF swapped as long as " Super Crashbug " remains on the field . Mr . Kay attacks " Utopia " with " Terror - Byte " and Astral tells Yuma to not dodge that attack . Yuma sends the last Overlay Unit of " Utopia " to the Graveyard to negate that attack . Mr . Kay Sets a card and ends his turn . " Achacha Archer " returns to Yuma ' s side of the field . Yuma draws a card and says that , if he doesn ' t defeat Mr . Kay this turn , " Utopia " will be finished . Astral gives advice , saying that , he may be wrong , but using " Zubaba Knight " and " Achacha Archer " to Xyz Summon " " could be a good idea . Yuma , who remembered that he had another Number s , Summons " Zubaba Knight " and overlays " Achacha Archer " and " Zubaba Knight " to Xyz Summon " Number 17 : Leviathan Dragon " . Yuma puts the blame of his 0 ATK " Leviathan Dragon " on Astral , saying that only happened because he butted in . Yuma then remembers that Astral would never tell him to do something stupid and realizes that he lied so that Yuma could bring " Utopia " to the field . Astral tells Yuma to activate the Spell Card " Thunder Short " and that , if he does , his victory is set . He adds that , this time , it ' s not a lie and that , if he doesn ' t activate " Thunder Short " , Astral will be obliterated from this world . Yuma activates " Thunder Short " and , through its effect , inflicts 500 points of damage for each monster his opponent controls . Mr . Kay activates a second " Damage Vaccine Ω MAX " , recovering the LP he lost . Yuma thinks that the Spell Card was just pointless but Astral tells him to use the Trap Card he had set before . Yuma activates " Overconfidence " , destroying " Super Crashbug " . The ATK of all monsters returns to normal . " Leviathan Dragon " destroys the 0 ATK " Terror - Byte " , while " Utopia " attacks directly , defeating Mr . Kay . Yuma , Tori and Caswell celebrate the victory , but Yuma still asks Astral how come he knew that Mr . Kay was going to recover his LP . Astral says that , since he was seeking a perfect victory , he decided to bet he would try to recover the damage from " Thunder Short " . Astral takes " Terror - Byte " from Mr . Kay , recovering another piece of his memory . With this memory , Astral sees a galaxy with blue and pink colors and remembers that he came to this world from the Astral World . Tori wakes up Mr . Kay and Yuma tells him to hurry up and stop the virus bomb but Mr . Kay says he can ' t because he doesn ' t have the deactivation switch . Meanwhile , Kari has finally managed to defeat the Crashbug Avatar with only ten seconds left but , even so , the timer didn ' t stop and reaches 0 . However , instead of the state of mass panic Yuma and his friends were expecting , the only thing that happens is that a building with its lights off goes on . With this , Mr . Kay tells his students to look at the sky with the D - Gazer s on . They do so and see in the sky the image of a giant " Crashbug " . Mr . Kay explains that the night view in the city makes the matrix code of that image , responding with the Duel Gazer s and materializing the Crashbug ' s picture . However , the code was incomplete because of the lights off in the building . Yuma asks Mr . Kay if all that perfection talk was just about putting light on a building and Mr . Kay says it was , leaving his students completely baffled . After that , Caswell gives Yuma his " Crashbug " card and tells him to read its text . While he does so , many other kids see Crashbug throwing bombs which create fireworks : " Crashbug , an electrical fairy that lives off of the other bugs . It becomes extremely powerful because it lives off its bug friends . It ' s said that those who witness its full moon - like appearance may forever live in happiness . " Caswell says that , to summarize , their teacher just wanted everyone to live forever in happiness . Astral says his Observation nº 7 : " My memory pieces , the Numbers cards . . . They grow the desire and darkness that dwells inside those they come into contact with . " Featured Duel : Yuma Tsukumo vs . Mr . Kay . " Duel continues from the previous episode " Turn 3 : Mr .

Due to the effect of " Super Crashbug " , all face - up monsters on the field have their original ATK and DEF switched ( " Terror - Byte " : 0 / 2900 → 2900 / 0 , " Utopia " : 2500 / 2000 → 2000 / 2500 , " Achacha Archer " : 1200 / 600 → 600 / 1200 ) .
