Yu - Gi - Oh ! Duelist - Duel 015 " Messenger From Hell " is the fifteenth chapter of " Yu - Gi - Oh ! Duelist " and the seventy - fourth chapter of " Yu - Gi - Oh ! " . It was first printed in Japanese in the " Weekly Shōnen Jump " magazine . It was reprinted in volume 2 of the " Yu - Gi - Oh ! Duelist " and volume 6 of the bunkoban . Summary . Dark Yugi has just exposed the thief he was Dueling as Mokuba Kaiba . Jonouchi , Anzu , Honda and Bakura look in astonishment and wonder why Mokuba would try to steal Dark Yugi ' s Star Chip s . Mokuba drops to the ground saying " no " and Dark Yugi wonders what he is doing on the island . Jonouchi calls Mokuba a weasel and demands that he hand back the two of Yugi ' s Star Chips that he managed to grab , but Mokuba refuses . Anzu tries a calmer approach and asks if Mokuba is still mad at Yugi . Mokuba replies that he is of course , after what Dark Yugi did to Seto Kaiba , his brother . Anzu sees that Kaiba has not recovered and Mokuba explains that he is still under 24 hour care in the mansion and the world ' s greatest doctors have looked at him , but reported that he may spend the rest of his life in the coma . Mokuba tells the others that he did not steal the Star Chips for revenge , despite what they may think . He says that they think they are smart , but they do not even know why Pegasus held the Duelist Kingdom tournament . He informs them that Pegasus needs to beat Yugi in order to take control of KaibaCorp . Dark Yugi is surprised to hear that Pegasus wants KaibaCorp . Jonouchi , Anzu and Honda can ' t make sense out of this and ask how beating Yugi will help him do that . Mokuba explains that Pegasus established himself as a genius game designer when he created " Duel Monsters " , but his company , Industrial Illusions , was not big enough , so he teamed up with KaibaCorp to develop the Virtual Battle Simulation Box . Kaiba designed the Battle Simulation Boxes , but after he lost to Dark Yugi in Death - T , he fell into a coma and KaibaCorp ' s stock plummeted without his management . Pegasus took this as an opportunity to buy the company and made an offer with KaibaCorp ' s leading stock holders , The Big Five . With Kaiba gone , The Big Five possessed 60 % of the company ' s shares and have all the decision making power . They liked Pegasus offer , but only accepted under the condition that Pegasus help rebuild their reputation . Since KaibaCorp had depended on the image of Kaiba being Japan ' s number one gamer , they lost the confidence of their investors after he lost to Yugi , so they wanted Pegasus to beat Yugi in an official Duel to regain that confidence . After doing that , Pegasus would be considered the chief executive . Dark Yugi laughed that Pegasus really is looking forward to beating him . However Mokuba told him not to laugh ; it is serious , he cannot beat Pegasus nor can anybody in the world . Kaiba had told Mokuba that Pegasus was unbeatable , so Mokuba thought if he could take Yugi ' s Star Chips and get him disqualified , he would not get to face Pegasus making his agreement with The Big Five void . Dark Yugi asks if that is why Mokuba came to the island . However Mokuba replies that that is not the case ; he was brought there by The Big Five because he has an important key . He tells them about how The Big Five came to his house one night to steal some documents from Kaiba ' s safe , so he swallowed the key to the safe in front of them . Anzu is slightly disturbed and asks " If the key ' s in your stomach . . . ? " Mokuba laughs about how The Big Five would come running every time he went to the bathroom . He vows not to let them get control of KaibaCorp , even if they rip open his guts . While he considers that Dark Yugi might not believe it , Mokuba explains that although Kaiba made Death - T to get revenge on the Yugis , his real dream was to build Kaiba Land amusement centers all around the world so that children can have fun . That is why Kaiba gave his life to KaibaCorp and that is why Mokuba will give his life to save KaibaCorp , he explains . Anzu tells Mokuba that she believes in him and politely asks if he can believe in the Yugis . She asks if he will return the Star Chips . Mokuba starts to consider it and Dark Yugi promises him that he will defeat Pegasus . Mokuba decides that he will trust Dark Yugi and begins to hand over the Star Chips . However Saruwatari appears and warns them that exchanging Star Chips outside of a Duel is a violation of the rules , punishable by disqualification . Saruwatari is glad to have finally found Mokuba after being sent on a wild goose chase . He grabs Mokuba by the arm and confiscates his Star Chips . Jonouchi tells him to hold on ; two of the Star Chips belong to Dark Yugi . However Saruwatari repeats that the only way to get Star Chips is by Dueling . In that case , Dark Yugi challenges Saruwatari to a Duel . He replies that he does not play games , but if Dark Yugi insists , he will arrange an opponent for him . He points to the Battle Box Dark Yugi and Mokuba had Dueled in , which is now occupied by someone . Kaiba appears to be in the Battle Box , but after looking closer , it becomes clear to them that it is just a puppet of Kaiba held by the Ventriloquist of the Dead . The ventriloquist tells Yugi that he will pay for what he did to him and begins repeating the word " revenge " . Dark Yugi considers the ventriloquist to be scum for making fun of Kaiba , one of the greatest gamers he ' s ever met and says that he will not forgive him . Mokuba protests that the puppet is not really Kaiba ; Kaiba is still in a coma , and tells Dark Yugi to beat the faker . Dark Yugi sits down and the puppet says " Today is the day . . . I k - k - kill you ! " . Dark Yugi ' s friends all urge him to beat the ventriloquist . Saruwatari thinks to himself that the ventriloquist is no ordinary Duelist invited to the island ; he is the first of a group of assassins brought to the island by Industrial Illusions to kill Yugi . He thinks that the puppet will disturb and enrage Dark Yugi putting him off guard , leading to his defeat and when that happens KaibaCorp will belong to Pegasus . Saruwatari looks at Mokuba and asks if he recognizes him . Mokuba then recognizes that he is Saruwatari , his bodyguard from KaibaCorp . A flashback shows him and another guard standing over Mokuba during Death - T . Saruwatari laughs that he is honored Mokuba remembers him and explains that back then he was a spy and had been reporting KaibaCorp ' s personal information to Pegasus . He says that that is not all he stole and tells Mokuba to just watch . Dark Yugi and the ventriloquist begin the Duel , each betting three Star Chips . The ventriloquist holds his hand of cards in his left hand and uses the puppet to draw and play his cards . He begins by Summoning " Battle Ox " , which Dark Yugi recognizes as a card also used by the real Kaiba . Dark Yugi Summons the " Dark Magician " and gets it to attack and destroy " Battle Ox " with its " Black Magic " attack . The ventriloquist has the puppet wail that Dark Yugi got him as his Life Points drop to 1200 . Dark Yugi is disturbed by the puppet and wonders how far the ventriloquist is going to go . Jonouchi notices that Dark Yugi looks stressed out despite winning . Anzu says it is because of the puppet . The ventriloquist has the puppet draw his next card and comment " The d - d - dragon of r - r - revenge has risen from Hell ! ! " and ask if Dark Yugi is ready . Much to Dark Yugi and Mokuba ' s surprise he Summons " Blue - Eyes White Dragon " . Saruwatari grins and says that he also stole Kaiba ' s Deck . Featured Duels .
