Episode 13

"Magical Sages Galilei & Kepler" (魔導賢者ガリレイ、ケプラー Madō Kenja Garirei, Kepurā), known as "Circus Surprise!" in the Dub version, is the thirteenth episode of the Yu-Gi-Oh! ARC-V anime.

Somehow, Reiji Pendulum Summons and mounts an attack against Yūya. Yūya shows off his ability to Pendulum Summon, something he thought only he could do, and tries to counterattack by Entertainment Dueling, but due to the sheer pressure from Reiji, he's unable to hide his shock. With You Show Duel School's fate on the line, Yūya is extremely anxious.

Summary
Yūya recaps that LDS's fourth player showed him his overwhelming power and strategy, remembering the Summonings of the Fusion, Synchro and Xyz Monsters.

Adjusting his glasses, Reiji declares his Battle Phase and he orders "DDD Flame King Temujin " to attack Yūya's "Entermate Whip Viper". Quickly, Yūya activates his Set card, "Hippo Carnival", Special Summoning three "Hippo Tokens" in Defense Position. Additionally, they are the only monsters that Reiji can attack. "Temujin" bisects one of the Tokens, and Tatsuya cheers that Yūya protected "Whip Viper". Gongenzaka agrees; now Yūya can mount a counterattack. Reiji continues with his attack, having "DDD Gust King Alexander" attack and destroy another "Hippo Token". Then he activates the effect of "Alexander", since it destroyed a monster by battle; Reiji can destroy one more monster. Yūya, "Whip Viper" and the remaining "Hippo Token" all react with horror as "Alexander" destroys the final Token with another slash of its one-handed blade and leaps back to Reiji's field. Reiji orders "DDD Wave King Caesar" to attack "Whip Viper", and both monsters leap forwards. "Caesar" destroys "Whip Viper" with one swing of its massive blade and leaps back to Reiji's field as Yūya's LP are reduced to 3300. Futoshi curses unhappily, as Reiji managed to destroy all of Yūya's monsters. Reiji Sets a card and ends his turn. Yūya calls Reiji's true strength amazing, admitting to being honestly shocked when he saw that Reiji could control all three Summoning methods. Now it's Yūya's turn. He doesn't control Fusion, Synchro or Xyz Monsters, but he has his own unique power that has been given to him. He declares that the fun has only just begun, and he draws.

He's drawn "Timegazer Magician", and thinks to himself in satisfaction that it's here. "Ladies and Gentlemen!" Yūya cheers. Apologizing to his fans for keeping them waiting, he declares that it's what they've all been waiting for, Yūya Sakaki's Entertainment Dueling that only Yūya Sakaki can do. Himika isn't fazed, but Yūya's friends are all excited. Ayu says that she's been waiting for this. Using the Scale 1 "Stargazer Magician" and the Scale 8 "Timegazer Magician," Yūya Sets the Pendulum Scale. The familiar writing appears on his Duel Disk, and the twin magicians appear in the blue columns of light. Yūya explains that now he can Summon multiple monsters from Levels 2 to 7. The large pendulum swings as Yūya chants "Swing, pendulum of the soul! Draw an arc of light across the aether! Pendulum Summon! Come forth, my monsters!" Two monsters emerge from the Pendulum portal, "Odd-Eyes Pendulum Dragon" and a new companion, "Entermate Fire Mufflio". Tatsuya cheers that there it is, the Pendulum Summon. Ayu adds that Yūya brought out a new monster, too, and Futoshi gets his "shivers." Yuzu tells Yūya that it's time for a counterattack, and Gongenzaka tells Yūya to do it. Shūzō tells Yūya that he's counting on him.

Spotlights snap on Yūya, and he asks for everyone's attention. It's time for fire acrobatics featuring their favorite superstar, "Odd-Eyes Pendulum Dragon". He dives from the platform, dons his goggles, and lands on the back of "Odd-Eyes", and tells his monster "let's go!" and declares his Battle Phase. "Odd-Eyes" attacks "Temujin", and Yūya chants, "With those dual-colored eyes of yours, lay waste to all that lies before you!" Leaping into the air, "Odd-Eyes" attacks with "Strike Burst of Spirals", blasting a black and crimson plume of flame at "Temujin". The Demon blocks the blast with its shield as Yūya explains that the effect of "Odd-Eyes" activates now - when battling a Level 5 or higher monster, battle damage is doubled. The orbs on the spines of "Odd-Eyes" glow as Yūya declares "Reaction Force!" and Odd-Eyes adds a surge of orange flame to its blast, destroying "Temujin" and reducing Reiji to 3000 LP. Tatsuya cheers, explaining to his friends that 500 times two is 1000 total points of damage. Ayu yells that Yūya's turned the tides. Furthermore, Yūya activates the effect of "Fire Mufflio", which allows a Pendulum Monster that has destroyed a monster in battle to make a second attack and gain 200 ATK. "Fire Mufflio" roars and lets loose an aura of flame that becomes a ring of fire. Yūya orders "Odd-Eyes" to jump through, and the Dragon leaps through the ring, with its ATK at 2700. Tatsuya cheers, and Yuzu is impressed that Yūya could use that move to power up "Odd-Eyes". Gongenzaka comments that Yūya is truly a wild animal tamer; no, a dragon tamer! Shūzō calls it real entertainment, burning and hot-blooded as Yūya targets "Alexander" for his next attack, with "Odd-Eyes" launching another "Strike Burst of Spirals". "Alexander" leaps into the air and blocks the blast with its sword, and Yūya then activates the effect of "Odd-Eyes" again, "Reaction Force". The second surge of flame destroys "Alexander" and reduces Reiji to 2600 LP as he grunts. Futoshi exclaims that he can't stop these shivers. Yūya and "Odd-Eyes" pass by an Action Card, and Yūya bends down to snag it, commenting that he's on a roll today. He activates the card, "Wonder Chance", allowing "Odd-Eyes" to attack again. "Odd-Eyes" attacks "Caesar". Before leaping up to meet the attack, "Caesar" absorbs one of its Overlay Units into its chest, and Reiji narrows his eyes. "Caesar" raises its sword, but it is destroyed in a single blast, reducing Reiji to 2300 LP. Ayu cheers that Yūya did it, he took out all of them, and Tatsuya adds that on top of that, Yūya managed to take out 1700 of Reiji's LP in one turn, while Futoshi has another bout of shivers. Yuzu states that, even if his opponent controls all three Summoning methods, as long Yūya has Pendulum Summoning, he can protect You Show Duel School. Shūzō tells Yūya that he's on fire, he really is the ace of their You Show Duel School. Dismounting "Odd-Eyes", Yūya thanks his audience for their cheers, and explains that "Fire Mufflio" can't attack this turn due to its own effect, so his attacks have come to an end, and the ATK of "Odd-Eyes" returns to normal. He bows deeply, and then he walks over to "Odd-Eyes", congratulating it. He looks over at the cloud of smoke clearing before Reiji and gasps in horror.

"Caesar", "Alexander", and "Temujin" are all standing on Reiji's field. Everyone is shocked, with Tatsuya protesting that Yūya just destroyed them. Yūya asks why, and Reiji explains that he activated the effect of "Wave King Caesar". By using an Overlay Unit, "Caesar" can Special Summon all of the monsters that were destroyed during the turn's Battle Phase at the end of the Battle Phase. Yūya and Gongenzaka are shocked, as Reiji admits that, of course, there is a risk for such a powerful ability; on his next turn, if he controls any monsters that were Special Summoned by this effect, he takes 1000 damage for each. Futoshi and Tatsuya muse that three monsters will mean 3000 damage, more than Reiji's 2300 LP, so Reiji will lose on his next turn. Sora interrupts, pointing out that he told them that wouldn't happen. He takes a bite out of his chocolate bar and comments that Reiji's too good for that. Sora is immediately proven correct as Reiji activates the Trap Card, "DDD Human Resources". It returns three "DDD" monsters from his field to the Deck, and then allows him to add two "DD" monsters from his Deck to his hand. All three "DDD" monsters vanish as two cards are ejected from Reiji's Deck, "DD Magical Savant Kepler" and "DD Magical Savant Galilei" - monsters with widened art frames. Sora points out that he told them so, with all three monsters gone, Reiji won't take any damage on his next turn now. Futoshi points out that all Reiji did was return his monsters to his Deck, and Ayu asks what's so great about the powerful ability of "Caesar". Both Sora and Tatsuya are worried about the two cards that Reiji added to his hand, though. Yuzu tells Yūya to keep it up, and just make it through with a smile on his face using his Entertainment Dueling. Yūya Sets a card ends his turn. He congratulates Reiji, calling him amazing. Everything Reiji does surpasses Yūya's expectations. He's looking forward to whatever surprises Reiji has in store for him next, but then he scratches his nose and claims he was just kidding. Reiji replies that likewise, Yūya has also done well. He has allowed Reiji to see the nature of Pendulum Summoning for himself with his own eyes. Now it's Yūya's turn. He'll have Yūya confirm with his own eyes whether.

Reiji draws, and then, using the Scale 1 "DD Magical Savant Galilei" and the Scale 10 "DD Magical Savant Kepler," he Sets the Pendulum Scale. The word appears on Reiji's Duel Disk, and two robotic pillars rise from the ground in blue columns of light, as Reiji explains that he can simultaneously Summon monsters from Level 2 to Level 9. Gongenzaka yells that those are Pendulum Monsters, and Sora and Yuzu gasp that it can't be. "Grand power which shakes my very soul!" Reiji chants as the Pendulum Monsters work. "Arise within me and give birth to a new light that rends the darkness! Pendulum Summon! Come before me, my monsters!" Unlike Yūya's Summon, no pendulum swings between the monsters, and only a purple mass of light surges from the portal as everyone gasps. "The three transcendent deities who rules over all kings!" Reiji chants. "DDD Death Great King Hell Armageddon!" he yells as a crystalline monster descends. And it's not just that one, another, and another "Armageddon" descends, for a total of three, each with 3000 ATK, as Sora observes. Yūya asks how Reiji can Pendulum Summon, but Reiji wastes no time in moving to his Battle Phase, attacking "Odd-Eyes Pendulum Dragon" with "Armageddon". As "Armageddon" charges an energy attack in its core, Yuzu pounds on the glass and yells Yūya's name, snapping him out of his daze. Yūya finds an Action Card, "Miracle", which will prevent "Odd-Eyes" from being destroyed and halve the battle damage. "Armageddon" blasts eight strands of black and purple lightning from its body, impacting "Odd-Eyes" and reducing Yūya to 3050 LP. Reiji comments that miracles only happen once, and attacks with the second "Armageddon", destroying "Odd-Eyes", and reducing Yūya to 2550 LP. Tatsuya points out that Pendulum Monsters don't go to the Graveyard when they're destroyed, and Reiji takes note of this as Yūya's Duel Disk shows "Odd-Eyes" going into Yūya's Extra Deck; he also notes that the same thing will happen to "Fire Mufflio" if it is destroyed. Reiji attacks "Fire Mufflio" as well, Yūya frantically running around, searching for an Action Card, but he's unable to find one in time as the attack from the final "Armageddon" strikes, reducing Yūya to 350 LP. Tatsuya gasps that Reiji did 2200 damage in an instant. Yuzu murmurs Yūya's name. Yūya wonders who Reiji is, and asks him how he can use Pendulum Summoning. Reiji's only answer is to Set a card and end his turn. Himika claps and calls Reiji splendid. If he's mastered Pendulum Summoning to this extent, then they have no use for You Show, and they can simply crush them. Fusion, Synchro and Xyz all belong to LDS. Shūzō is shocked that Reiji would use Pendulum Summoning, and wonders just how much power Reiji has. Then he notices the still shell-shocked Yūya on his screen, and he reminds Yūya that the match isn't over yet, and reminds him him to keep burning and be hot-blooded. Yūya agrees and urges himself to calm down, he has to protect You Show. He looks up at the three "Armageddons", musing that those are Reiji's Pendulum Monsters, despite Pendulum being something only given to Yūya. Then he shakes his head and tells himself not to think about it, if Yūya doesn't win this Duel, the Duel School will...

Yūya declares his turn and muses that since his hand is at zero, this draw will decide everything. He draws, getting his "Entermate Partnaga", and then he Pendulum Summons again, bringing forth the monsters that left the stage, "Odd-Eyes Pendulum Dragon" and "Entermate Fire Mufflio", as well as "Partnaga" from his hand. Futoshi cheers that this time Yūya brought forth three monsters at once. Gongenzaka adds that Yūya's still ready to fight, and Yuzu shouts encouragement. Yūya activates the effect of his "Partnaga", targeting "Odd-Eyes". When "Partnaga" is Special Summoned, he can increase the targeted monster's ATK by 300 for each "Entermate" monster he controls. "Partnaga" spreads its body out to attach to one of the horns of "Odd-EYes" and grabs the tail of "Fire Mufflio" with the hand on its own tail, causing "Odd-Eyes" to glow with yellow light and power up to 3100 ATK. Yūya thinks that everything is set: first, he'll use the powered up "Odd-Eyes" to destroy one "Armageddon", using the effect of "Odd-Eyes" to double the battle damage to 200, reducing Reiji to 2100 LP, and then he'll power up "Odd-Eyes" again with "Fire Mufflio", to 3300 ATK and have it attack again, destroying the second and reducing Reiji to 1500 LP. Then, he can use his Trap Card, "One Two Jump", to have "Odd-Eyes" attack a third time and halve the ATK of the final "Armageddon". With Reiji having 1500 LP left, Yūya can win. Yūya leaps on "Odd-Eyes" and attacks the first "Armageddon" with its "Strike Burst of Spirals", then Yūya reminds Reiji that the effect of "Odd-Eyes" doubles the battle damage with a Level 5 or higher monster, and "Odd-Eyes" activates its "Reaction Force" effect, the extra fire destroying "Armageddon" and reducing Reiji to 2100 LP. Reiji in turn reminds Yūya that destroyed Pendulum Monsters are sent to the Extra Deck, holding up his card. He begins to activate the effect of "Fire Mufflio", but Reiji interrupts him with the effect of "Armageddon". When one of Reiji's monsters is destroyed, the remaining "Armageddons" can gain the ATK of the destroyed monster. Dark power flows into the two monsters as Reiji reminds them that "Armageddon" had 3000 ATK, so the other two will gain that value. Both "Armageddons" increase to 6000 ATK, and the group look on in shock, asking how one would even defeat such a monster. Sora comments that this is going to be rough, but he alone seems excited, as everyone else believes that this is the end. Reluctantly, Yūya ends his turn and the ATK of the "Armageddons" decrease back to their substantial 3000.

Reiji starts his turn and draws a card. And then both "Galilei" and "Kelper" begin shaking violently, covered in lightning. Their Pendulum Effects appear on the cards, and their Scales shrink to 2 and 5. This is reflected by the glowing numbers changing in the blue light columns, with the Scale of "Galilei" doubling to 2, and the Scale of "Kepler" halving to 5. Lightning strands extend from the two Pendulum Monsters and destroy the two "Armageddons", much to everyone's shock, especially Reiji's. Sora observes that the destruction of the monsters must have had something to do with the Pendulum Scale shrinking just now. Gongenzaka yells that it's a chance, and Yuzu points out that Reiji can only Pendulum Summon Level 3 and 4 monsters now. This reminds Yūya of the effect of "Partnaga", which prevents Level 4 or lower monsters from attacking, so no matter what monsters Reiji summons... Reiji muses that in the end, his monsters were just prototypes, and they were still unstable. He looks at his Set card, thinking that, in this situation... and then he realizes something. He begins to laugh madly, his face twisting beneath his hand. He asks himself why he didn't realize it until now - Pendulum Summoning is not complete yet. Yūya gasps in shock, and Reiji explains that he's seen the possibility for evolution in Pendulum Summoning, and he'll have Yūya bear witness to it at this moment. Yūya can only wonder what Reiji is talking about.

"What did you say?" Himika gasps, catching the attention of both Reiji and Yūya. But she's not talking to them, Nakajima is whispering in her ear. Masumi, the closest, gasps "Professor Marco was...!" causing both Yaiba and Hokuto to react as well. Himika calls out to Reiji, who pops up a screen on his Duel Disk to communicate with Nakajima, who informs him of the situation, causing Reiji to narrow his eyes. Reiji promptly leaps from ball to ball and starts walking out of the arena. When Yūya asks Reiji to wait, Reiji explains he'll give Yūya the win. Yūya asks to know Reiji's name, and Reiji tells him that his name is Reiji. Reiji leaves Yūya to murmur his new rival's name.

Yūya Sakaki vs. Reiji Akaba
Duel continues from the previous episode.

Yūya has 4000 LP remaining, 4 cards in his hand, and controls "Entermate Whip Viper" (CG Star 4/1700/900) in Attack Position and 1 Set card. Reiji has 4000 LP remaining, 4 cards in his hand, and controls "DDD Flame King Temujin" (CG Star 6, 6/2000/1500), "DDD Gust King Alexander" (CG Star 7, 7/2500/2000) and "DDD Wave King Caesar" (Rank Star 4, 4/2400/1200) all in Attack Position and no Set cards.

Turn 3: Reiji

"DDD Flame King Temujin" attacks "Entermate Whip Viper", but Yūya activates his face-down "Hippo Carnival", Special Summoning three "Hippo Tokens" (CG Star 1/0/0 each) in Defense Position. Their effects prevent other monsters he controls from being targeted for attacks, so "Temujin" attacks and destroys a "Hippo Token". "DDD Gale King Alexander" attacks and destroys another "Hippo Token". As it it destroyed a monster by battle, the effect of "Alexander" activates, letting it destroy a monster Yūya controls. The third "Hippo Token" is destroyed. "DDD Wave King Caesar" attacks and destroys "Whip Viper" (Yūya: 4000 → 3300 LP). Reiji Sets 1 card.

Turn 4: Yūya

Yūya draws "Timegazer Magician" and subsequently places it (Left Pendulum Scale 8) and "Stargazer Magician" (Right Pendulum Scale 1) in his Pendulum Zones. Yūya Pendulum Summons "Odd-Eyes Pendulum Dragon" (CG Star 7/2500/2000) and "Entermate Fire Mufflio" (CG Star 3/800/800), both from his hand in Attack Position. "Odd-Eyes" attacks and destroys "Temujin", with the former's effect doubling the battle damage as it is battling a Level 5 or higher monster (Reiji: 4000 → 3000 LP). As a Pendulum Monster he controls destroyed an opponent's monster by battle, Yūya activates the effect of "Mufflio", increasing the ATK of "Odd-Eyes" by 200 ("Odd-Eyes": 2500 → 2700/2000) until the end of the Battle Phase and allowing it to attack again, but "Mufflio" itself may not attack. "Odd-Eyes" attacks and destroys "Alexander", with the effect of "Odd-Eyes" doubling the battle damage (Reiji: 3000 → 2600 LP). Yūya finds and activates the Action Card "Wonder Chance", giving "Odd-Eyes" an additional attack. "Odd-Eyes" attacks and destroys "Caesar" (Reiji: 2600 → 2300 LP), with Reiji activating the effect of "Caesar", detaching an Overlay Unit to Special Summon all monsters he controls that were destroyed by battle this turn at the end of the Battle Phase, but during his next Standby Phase, he will take 1000 damage for each one he still controls. The Battle Phase ends and Reiji Special Summons "Temujin" (CG Star 6, 6/2000/1500), "Alexander" (CG Star 7, 7/2500/2000) and "Caesar" (Rank Star 4, 4/2400/1200), all in Attack Position. The effect of "Mufflio" expires ("Odd-Eyes": 2700 → 2500/2000). Reiji activates his face-down "DDD Human Resources", letting him return three "DDD" monsters to his Deck and add two "DD" monsters from his Deck to his hand. He returns "Temujin", Alexander" and "Caesar" to his Extra Deck and adds "DD Magical Savant Kepler" and "DD Magical Savant Galilei". Yūya Sets 1 card.

Turn 5: Reiji

Reiji places "Kepler" (Left Pendulum Scale 10) and "Galilei" (Right Pendulum Scale 1) in his Pendulum Zones. He Pendulum Summons three "DDD Death Great King Hell Armageddon" (CG Star 8, 8, 8/3000/1000 each), all from his hand in Attack Position. The first "Armageddon" attacks "Odd-Eyes", but Yūya finds and activates the Action Card "Miracle", halving the battle damage and preventing "Odd-Eyes" from being destroyed by battle (Yūya: 3300 → 3050 LP). Another "Armageddon" attacks and destroys "Odd-Eyes" (Yūya: 3050 → 2550 LP), which is sent to the Extra Deck. The last "Armageddon" attacks and destroys "Mufflio" (Yūya: 2550 → 350 LP), which is sent to the Extra Deck. Reiji Sets 1 card.

Turn 6: Yūya

Yūya draws "Entermate Partnaga". He Pendulum Summons "Odd-Eyes" (CG Star 7/2500/2000) and "Mufflio" (CG Star 3/800/800) from his Extra Deck and "Partnaga" (CG Star 5/500/2100) from his hand, all in Attack Position. The effect of "Partnaga" activates upon its Summon, allowing Yūya to target a monster he controls and increase its ATK by 300 for each "Entermate" monster he controls. Yūya targets "Odd-Eyes" ("Odd-Eyes": 2500 → 3100/2000). At this point, Yūya envisions a plan to win the Duel: he can attack and destroy an "Armageddon" with "Odd-Eyes"; then he can use the effect of "Mufflio" to give "Odd-Eyes" 3300 ATK and allow it to attack and destroy another "Armageddon", reducing Reiji's LP to 1500; then he can activate his face-down "One Two Jump" as "Odd-Eyes" has destroyed two monsters this turn, which will halve the ATK of Reiji's third "Armageddon" and allow "Odd-Eyes" to attack it for 3600 damage. "Odd-Eyes" attacks and destroys an "Armageddon" (Reiji: 2300 → 2100 LP), which is sent to the Extra Deck. The effects of both remaining "Armageddons" activate; since a monster Reiji controls left the field, they each gain ATK equal to the original ATK of that monster until the end of the turn ("Armageddons": 3000 → 6000/1000 each). At the end of the turn, the effects of both "Armageddons" expire ("Armageddons": 6000 → 3000/1000 each).

Turn 7: Reiji

During Reiji's Standby Phase, "Galilei" and "Kepler" appear to malfunction in their Pendulum Zones, and their Pendulum Effects appear on their cards: "Galilei" doubles its Pendulum Scale ("Galilei": Left Pendulum Scale 1 → 2) and sends to the Graveyard all Pendulum Summoned monsters he controls whose Levels are lower than its Scale, while "Kepler" reduces its Scale by 5 ("Kepler": Right Pendulum Scale 10 → 5) and sends to the Graveyard all Pendulum Summoned monsters he controls whose Levels are higher then its Scale. Since the Levels of the "Armageddons" are higher than the Scale of "Kepler", they are sent to the Graveyard. At this point, Reiji is called away, so he surrenders.
