Yu - Gi - Oh ! 5D ' s - Ride 020 " Shadow Card ! ! " , known as " The Card of Darkness ! ! " in the Japanese version , is the twentieth chapter of the " Yu - Gi - Oh ! 5D ' s " manga . This chapter was first printed on March 21 , 2011 in the 04 / 2011 issue of the " V Jump " magazine . It was later reprinted in volume 3 of the . Summary . Jack ' s " Magic King Moon Star " attacks Sect directly with " Star Flash " and reduces his Life Points from 3300 to 2400 . Despite only 900 damage being dealt , Sect experiences a powerful shockwave from Jack ' s Sense . Setting a card , Jack ends his turn as he rides atop a row of containers above Sect , and calls Sect a scum - dwelling cockroach , telling him that it ' s his turn . Beginning his turn , Sect Sets a card and Summons " Spin Mosquito " , then sends the " Great Poseidon Beetle " in his hand to the Graveyard to allow " Spin Mosquito " to attack Jack directly . As the monster spins towards Jack , he snorts , accelerating his Duel Runner as his Life Points are reduced to 3500 , taking his first damage . He asks Sect in contempt if that ' s his Sense , and comments that being bitten by a real mosquito would have hurt him more . He explains that his " Sense Excluder " uses his own Sense to cancel out his opponent ' s ( explaining why Yusei ' s was ineffective against him ) , and asks Sect if he thought that a " cockroach ' s Sense " would affect the King . Jack begins his next turn , drawing the Tuner monster " Dust Lord Ash Gash " . He thinks that he could use the Level 3 " Magic King " and the Level 4 " Dust Lord " to Synchro Summon the Level 7 " Dark Highlander " , but it would seal Sect ' s Synchro Summons , and put his goal - the Shadow card - out of reach . He knows that he can ' t end Sect that easily , until he lures out the Synchro Monster that he ' s been searching for . Instead , he Summons the Tuner monster " Phantom King Hyde Ride " , a Level 3 monster , tuning it with " Magic King " and chanting ; " Sirius ! Wolf Lord Blue Sirius ! You who scorch the heavens ! Tear apart these earthbound , toothless dogs ! " as he Synchro Summons " Celestial Wolf Lord , Blue Sirius " . He attacks " Spin Mosquito " , and " Blue Sirius " swiftly destroys the Insect and punches Sect ' s Duel Runner , knocking it off course . He tells Sect , calling him a cockroach again , that they ' re in the middle of a Turbo Duel , and not to fall into the ocean . He thinks to himself that he held back for Sect and didn ' t Summon " Dark Highlander " , and mentally urges Sect to bring out that card . Recovering , Sect draws " Malevolent Mayfly " , and grins as he activates his Set card , " Call of the Haunted " , using it to revive " Great Poseidon Beetle " . He warns Jack that he called him a cockroach , and he ' s going to pay for it . Yusei races for the docks , recognizing " Great Poseidon Beetle " and wondering if Sect is fighting a Turbo Duel , and against who . His question is immediately answered as Jack leapts a gap in the containers , much to Yusei ' s shock . Yelling Sect ' s name , he catches up to him , and Jack recognizes him as the " Satellite trash " . Yusei asks Sect why he ' s Dueling Jack , but Jack tells Yusei to stay out of it , as it is none of his business . Or maybe he ' d like to join his buddy , the cockroach , and take Jack on as a team ? Both Yusei and Sect are furious , and Sect explains that he wants to get stronger . When Yusei lost to Jack , it really got to him . Sect ' s like that too , he was always made fun of when he lost a Turbo Duel , which was always frustrating . But he ' s felt that way for the last time ; he ' s got power now , enough to lay out anyone who ' s ever looked down on him . Yusei asks Sect what he ' s saying , but Sect doesn ' t answer , and instead Summons " Malevolent Mayfly " - a Tuner monster . Yusei is shocked , remembering that Sect doesn ' t have any Synchro Monsters in his Deck . Sect then accuses Yusei of looking down on him , all this time . Yusei protests that he considered Sect his rival , but Sect tells him to shut up and drop the big brother act , claiming that Yusei makes him sick . Shadow Miasma explodes from Sect , much to Yusei ' s horror , as Sect tunes his Level 7 " Great Poseidon Beetle " with his Level 1 " Malevolent Mayfly " . Jack triumphantly urges Sect mentally to Summon that Level 8 monster , while Yusei notes that the sky , which was previously red with sunset , is now being smothered by darkness . Sect begins to chant ; " Lord of the flies , you who lead demon gods ! Cast your shadow on this disgusting world ! " as he Synchro Summons " Beelze , King of Dark Dragons " , a gigantic fly - like dragon monster with twin heads and the upper torso of a woman protruding from the top of the monster . Yusei is shocked at the 3000 ATK of the ominous monster , while Jack is floored himself as it ' s not the monster he was looking for . Sect tells Jack that it ' s his monster ' s turn to get chewed up , and " Beelze ' s " twin heads rip " Blue Sirius " in two with " Beelze Carnival " . Though not the target of the Sense , Yusei thinks that he could never forget it - it ' s Shadow Sense . Jack thinks that it ' s nothing , as he can cancel it with his Sense Excluder , but the shockwave hits him and his Life Points fall to 2900 ; his Sense Excluder unable to cancel out the Shadow Sense . Sect states that he isn ' t done yet . He ' ll show Jack Shadow Sense like he ' s not going to believe , and laughs as the Shadow Miasma surrounds him . He accelerates ahead of Yusei , who calls out his friend ' s name . Jack scoffs at the power of the Shadow card , the Shadow Sense . He wipes blood from his mouth , thinking that in that case , he ' ll take out Sect ' s Shadow card with the King ' s Sense . Featured Duel : Sect Ijuin vs . Jack Atlas .
