Yu - Gi - Oh ! R - Duel Round 028 " Apex Arena ! ! " is the twenty - eighth chapter of the " Yu - Gi - Oh ! R " manga . It was first printed in Japan on August 19 , 2006 in V Jump magazine . It was later reprinted in volume 4 of Yu - Gi - Oh ! R . Summary . Willa Mette lies on top of the KaibaCorp oration Building , but is roused from his rest by the activation of a panel near Kaiba ' s fighter jet . Getting up , he wonders what ' s going on , before there is a burst of light . Laughing , he comments that that is something as he sees Seto Kaiba and Yako Tenma standing on top of a Duel Field that has been elevated from the inside of the building . Kaiba looks down at Willa in disdain , asking if he ' s still here . He can ' t believe that Yako has been letting goons like him overrun his building , and he ' s so furious he doesn ' t know where to start . Yako replies that even as he rages , his Project is nearing completion . If Kaiba is a Duelist , he cannot defy the laws of power . In other words , Kaiba doesn ' t have what it takes to stop the Project . Kaiba angrily asks if Yako ' s saying that Kaiba will lose to him , but Yako doesn ' t reply , and Kaiba tells him that getting the Wicked Gods has bloated his ego . If he ' s truly worthy of owning a God , then he should prove it , and show it to him . After he tears Yako apart , he and his Gods will grovel at his feet . Yako laughs softly , and Kaiba vows to reset his entire Project to zero , as the Duel begins . Kaiba starts , Setting a card and Summoning " Material Bat " in Defense Position to end his turn . Yako chuckles as he begins his turn , but only Sets two cards and ends his turn without Summoning a Monster . Willa wonders what ' s up with Yako , is it card trouble ? Kaiba wonders the same thing , or is Yako laying a trap ? He draws , Summoning " Material Lion " and attacking directly , thinking that Yako ' s Traps don ' t scare him . " Material Lion " successfully attacks with " Scratch Claw , " reducing Yako to 2200 Life Points . Kaiba is shocked that Yako didn ' t take any steps to protect himself , taking all the damage instead . He comments that Yako didn ' t activate a Counter Trap Card when he Summoned his monsters or when he attacked . He takes it that means those face - down cards of Yako ' s are an empty bluff . Yako replies that they ' ll see . . Frowning , Kaiba Sets a card to end his turn . As Yako draws , Kaiba wonders what his strategy is . Yako simply Sets another card and ends his turn . Kaiba is floored , and Willa comments that Yako ' s got guts . He wonders if he ' s using Spell and Trap cards without monsters . Playing against such a Deck can be tricky , but he can ' t see it working on Seto Kaiba . Kaiba has come to the same conclusion , and thinks that it ' s absurd that Yako is using a Traps - and - Spells Deck against him . He looks at the " Blue - Eyes White Dragon " in his hand , thinking that he won ' t even have to use his trump card . He ' ll finish him off this turn . Drawing , he Summons " Material Scorpion , " and Yako realizes what Kaiba ' s about to do . Since Kaiba has three " Material " monsters on the field , he can fuse them into one Chimera . Yako realizes that it ' s an " automatic unit " self - fusing monster , and Kaiba fuses his three monsters into the mythical beast , " Mosaic Manticore " . Yako activates a Trap , and another " Mosaic Manticore " appears on his field . Yako explains that his " Chronic Déjà Vu " Trap card Summoned a monster identical to the one that Kaiba just Summoned . Kaiba appears to be stuck , thinking that if he attacks , both monsters will be wasted and will end up destroying one another . But then he laughs , asking Yako if he thought such makeshift tactics would work on him . He plays his Field Virus Card , " Alpha - Wave Emission , " draining 300 ATK from every monster on the field and preventing them from attacking . Both " Mosaic Manticores " fall to 2500 ATK , as Yako points out that that goes for Kaiba ' s Manticore as well . Kaiba just laughs , playing " Vaccination " to vaccinate his " Mosaic Manticore " and make it immune to the Virus . He orders his " Manticore " to attack with " Fire Breath " and destroys Yako ' s " Manticore , " reducing Yako to 1900 Life Points . Laughing , Kaiba admits that when " Mosaic Manticore " is destroyed , part of the Summoning Material remain on the field . " Material Lion " and " Material Bat " are on Yako ' s field , as Kaiba further explains that a Chimera is any kind of monster created from other parts of animals . He could Summon another " Material " monster and fuse them into a Chimera again , but Yako doesn ' t have any " Material " monsters , does he ? He tells Yako to draw . Yako does so , sacrificing his two " Material " monsters to Summon " Belial - Marquis of Darkness . " Its effect prevents Level 7 or lower monster cards from attacking it , preventing the Fusion of Level 4 monsters from attacking it . Kaiba comments that he sees . So this is all Yako is worth as a Duelist . Yako is surprised as Kaiba asks if he thought that he could beat him with such a half - baked strategy . Kaiba draws , commenting that the card he needs to crush Yako is already in his hand , and sacrifices two of " Mosaic Manticore ' s " component parts ( " Material Bat " and " Material Scorpion " ) to Summon his " Blue - Eyes White Dragon . " It inherits the vaccine given to the sacrificed " Mosaic Manticore " and is unaffected by the Virus , allowing it to attack and destroy " Belial " with " Burst Stream of Destruction , " reducing Yako ' s Life Points to 1400 . Kaiba tells Yako that he isn ' t qualified to possess a God , and tells him to leave his God cards and get off his property now . Featured Duel : Seto Kaiba vs . Yako Tenma .
