This chapter was first printed in Japanese in the 8 / 2013 issue of " V Jump " , released on June 21 , 2013 , and in English in the 6 / 24 / 2013 issue of " Weekly Shonen Jump " . Summary . Kaito and Shark both fall to 500 Life Points as Yuma asks what is going on . Shadow laughs , commenting that the trap activated perfectly . As Kaito and Shark hand from " " and " " respectively , he explains that he lost Duels to them on purpose so that they would take the " Number s , " which will continue to activate automatically and inflict damage with excruciatingly painful attacks . He wonders if they can hold up once their Life Points are gone , and both Luna and Orbital 7 voice their displeasure at Shadow ' s tactics . Shadow comments to Yuma and Astral that now their enemies will disappear , commenting that it ' s convenient for them . Yuma expresses confusion , and Shadow points out that Yuma would eventually have to fight them . Yuma protests that it was Shadow and his cohorts who started the Numbers War and that he doesn ' t see Kaito or Shark as enemies . If you Duel someone you understand them , and you can be friends , he claims . Shadow is the only enemy that they need to take out . Kaito and Shark both deny being friends with Yuma , and Shadow is surprised by Yuma ' s naivety . But he can use this to finish them off now . Shadow offers Yuma and Astral a chance to save Kaito and Shark , by Dueling him . If they defeat Shadow , then the " Numbers " will lose their power . Yuma agrees , but Astral tells him to wait , knowing both that Shadow is plotting something , and that Kaito and Shark only have 500 Life Points left ; they won ' t be able to win in one turn . Shadow teleports in front of them , agreeing . But that would be boring , so Shadow will make a special rule just for them . He ' ll increase their Life Points by reducing Yuma and Astral ' s own . Astral states that he knew it , and Shadow asks if they ' ll accept . Both Shark and Kaito tell Yuma to leave them alone , but Yuma offers Shadow 2000 Life Points , 1000 for each . Astral protests as Shadow mocks Yuma . Yuma tosses his bag aside and takes out his D - Pad , as Astral reminds him that they will have to win somehow with 2000 Life Points . Yuma yells that he knows , but he can ' t just abandon Kaito and Shark . Astral protests further that they are one a mission to save both the Astral World and this one , and Yuma agrees , but he can ' t watch someone suffer in front of him . He asks Astral to believe in him the way Yuma believed in Astral when they fought Thunder Spark , and Astral remembers the encounter . Yuma states that Astral only has to believe in the power of believing in people and Astral agrees , but suggests that they give Shadow 2002 Life Points , so that a single Life Point can keep Kaito and Shark alive for an additional turn , since if they only gained 1500 Life Points , the 500 points per turn that the " Numbers " would take would only last three turns . Shadow agrees , and both Shark and Kaito rise to 1501 Life Points . Luna is shocked that Yuma would do what he did , despite being their enemy , wondering if he ' s confident or just an idiot . The Duel begins , with Yuma vowing to rescue Kaito and Shark . Shadow takes the first turn , drawing a card . He Summons " Splitting Planarian " and immediately activates its effect , allowing him to banish it to Special Summon two " Shadow Planarian s " from his Deck . Then he overlays his two Level 3 monsters to Xyz Summon his " Number " , " . " Unable to attack , Shadow Set s a card and ends his turn , which means that Kaito and Shark ' s Duel continues . " Cain ' s Doom " attacks , and the damage is dealt to both of the Duelists , reducing them to 1001 Life Points . Shadow comments that they only have three turns left , and Yuma yells at them to hang on . He draws a card and Special Summons " Swift Hippo Dynatherium , " which allows Shadow to Special Summon a monster of the same Level - 4 - from his Graveyard , but Shadow doesn ' t have any . Then he Summons " Gagaga Magician " and immediately overlays them . Shadow observes that Yuma is playing his trump card already as Yuma Xyz Summons " . " Yuma thinks that " Utopia " can handle " Shadow Lich ' s " 1800 ATK and attacks , but Shadow snaps that it won ' t work , using " Shadow Lich ' s " ability to place " Phantom Tokens " on the field and hide among them . Shadow comments that even if the 500 ATK Token is destroyed , he won ' t take any damage and wonders what they ' ll do now . Astral asks if Shadow is simply stalling until Kaito and Shark ' s Life Points run out , and states that their attack only has a 20 % chance of success . Yuma decides to take out the middle one , but misses , and he takes 500 damage from the " Phantom Token ' s " effect , reducing him to 1498 Life Points . Astral realizes that attacking the wrong Token will mean that they take the damage , and Yuma Sets a card to end his turn . Kaito and Shark ' s Duel continues and their screams of pain alert Yuma as their Life Points fall to 501 . Shadow comments that they only have two turns left to live and he draws . Yuma protests that " Shadow Lich ' s " low ATK will prevent it from attacking , but Shadow activates his monster ' s second effect , allowing it to gain the ATK of the other Tokens . " Shadow Lich " swells as it rises to 3300 ATK , and it raises its scythe to attack " Utopia . " Astral tells Yuma to use " Utopia ' s " effect , and Yuma begins to do so , but Shadow calls them predictable , activating his Trap Card , " Xyz Stun , " negating the effect of their Xyz Monster . Astral quickly orders Yuma to use their Trap , and Yuma activates " Half Unbreak " to prevent his monster ' s destruction and halve the battle damage . He ' s thrown backwards as his Life Points fall to 1098 . Both Kite and Shark express concern , but soon they have to worry about each other as their Duel continues . " Cain ' s Doom ' s " attack reduces them both to a single Life Point , and Shadow laughs , commenting that all three of them are done for . Featured Duels .

Shadow makes an offer for Yuma to give up his Life Points in exchange for Kaito ' s and Shark ' s Life Points .
