Dark Yugi , Jonouchi , Anzu , Honda and Bakura leave the cliffs after the Duel between Dark Yugi and Kajiki . Kajiki waves to them as they leave . Jonouchi thinks that there ' s something about Kajiki that you just can ' t hate , while Anzu guesses that the Duelists on the island must all have their own hopes and dreams . With Jonouchi on two Star Chip s and Dark Yugi on five , they continue to search for more opponents . Five hours into the tournament , they see a boy being restrained by Saruwatari over , while a number of other Duelists stare in surprise . Saruwatari says that he can see the boy has lost all his Star Chips , so he has to leave the island . He argues that his Star Chips along with his cards were stolen , but Saruwatari isn ' t interested in how he lost them and states the rules are that you must leave the kingdom if you run out of Star Chips . Dark Yugi deduces that Saruwatari must work for Pegasus . Jonouchi tries telling Saruwatari to let the boy go and says that having Star Chips stolen is not the same as losing a Duel . Saruwatari replies that other participants are forbidden to interfere and doing so will result in their disqualification . Jonouchi asks the boy what the thief looked like and offers to find him . The boy explains that he couldn ' t see the thief ' s face because he wore a bandanna and that he had been challenged to a Duel , but the moment he put his Deck and Star Chips down , the thief grabbed them and ran . Jonouchi asks which way he ran and the boy points to his left . Vowing to catch the thief , Jonouchi asks that Saruwatari not evict the boy until then . Saruwatari just says that he will think about it . Jonouchi declares that Star Chips are a Duelist ' s life and that he won ' t forgive anyone for killing people or stealing their Star Chips . He then turns to the boy and informs him that if he does catch the thief he will taking half the Star Chips as payment . Honda sighs that Jonouchi is a terrible altruist and the group head off in search of the thief . Meanwhile someone stares at them from the bushes . Meanwhile Saruwatari takes out his walkie - talkie and contacts Pegasus , informing him that he located a certain kid in block D and requests that all personnel be sent there . He says that they will capture him and bring him back to the castle . He wonders where the thief went and then takes the boy , whose Star Chips were stolen , by the neck and announces that he is leaving the island because he has no Star Chips . At the castle , Pegasus is sitting in a dining area , while Croquet stands behind him . Portraits of Shadi and a young woman are hung from the wall . Pegasus considers himself to be blessed among men as he sips on fine wine , eats well aged gorgonzola cheese and laughs at the American comic " Funny Rabbit " , which he considers to be the best comic in the world . Within the comic , Funny Rabbit tries to escape being eaten by a crocodile . Pegasus asks Croquet about the status of the Duels . He is informed that after six hours of dueling twelve of the forty participants have been eliminated and the first ship of evacuees will be leaving soon . Pegasus inquires about Yugi ' s status and is told that he is still in the running with five Star Chips . Pegasus is delighted and says that Yugi must make it to the finals . Finally he asks if they have managed to located a certain boy yet . Croquet replies that they haven ' t managed to yet . Pegasus thinks it is a shame that he ran away after being invited to the castle as a private guest and comments that he must not have liked the reception . Croquet apologizes , but Pegasus insists that there is no need to worry as he has a good idea of what ' s on the boys mind . He advises Croquet to keep his eyes on Yugi as that is where the boy is heading and when they capture him , they are to lock him up in the dungeon this time . He then goes back to reading " Funny Rabbit " to spend his time until the Duel . Dark Yugi , Jonouchi , Anzu , Honda and Bakura continue to search the island for the thief to no avail . Anzu suggests that they give up , but Jonouchi doesn ' t want to as has his eyes set on the Star Chips reward . Honda thinks to himself that Jonouchi isn ' t very good at this " Way of the Duelist " thing . Dark Yugi notices a boat of Duelists leaving the island . The boat is captained by one of Pegasus ' suits . Among the evacuees are Insector Haga and the boy who had his Star Chips stolen . Haga demands that the others give them space , reminding them that he is the champion of Japan . The other boy looks at Haga and wished his Star Chips had not been stolen . Jonouchi sees the boy , who had his Star Chips stolen , on the boat and realizes that Saruwatari broke his promise . He curses Saruwatari and thinks he has lost the chance to claim the Star Chip reward . Dark Yugi watches the boat and thinks that those who lose their Star Chips are forced off the island ; that is the fate of those who lose the game . A boy wearing a bandanna jumps out of the bushes and calls Dark Yugi . Seeing the bandanna , Jonouchi assumes that this must be the thief . Dark Yugi asks the boy if he wants the Duel him . The boy nods , so they make their way to a nearby Battle Box to commence . As the two sit down , Jonouchi admits he is surprised that Dark Yugi accepted the Duel just like that . Dark Yugi asks how many Star Chips they are betting and the boy holds up five fingers . Dark Yugi removes his chips from his Duel Glove , while the boy roots his out of his pocket . The lack of a Duel Glove tells Dark Yugi that this boy must be the thief and that he wasn ' t one of the Duelists chosen be Pegasus to come to the island . He wonders if the boy stole the Star Chips just to challenge him and wonders why he would go so far . He then gets a hunch about something . Jonouchi is certain that Dark Yugi knows that the boy is the thief . Honda wonders why he accepted the Duel in that case . And Anzu wonders if it means Dark Yugi knows who the boy is . The thief Summons " Man - Eating Plant " , which has 800 ATK , but Dark Yugi counters with " Winged Dragon , Guardian of the Fortress " , which has 1400 ATK . The dragon attacks from the sky and defeats the plant , dropping the thief ' s Life Points to 1400 . The thief gulps and proceeds to Summon " Crocodilus " , which has 1100 ATK . This time Dark Yugi counters with " Celtic Guardian " , which has 1400 ATK . It cuts " Crocodilus " in half , destroying it and dropping the thief ' s Life Points to 1100 . The thief sees that he ' s in real danger of losing . Jonouchi thinks that the thief is not very good and Anzu agrees that he is no match for Dark Yugi . Dark Yugi advises the thief to give up , as the game is not so simple that it can be won with stolen cards . The thief makes a grab for the Star Chips , but Dark Yugi catches him by the wrist , before he can run . Dark Yugi notices something about the thief and says that he knew it . He removes the thief ' s hat and bandanna , revealing that he is Mokuba Kaiba . Mokuba Summons " Man - Eating Plant " ( ATK : 800 ) . Dark Yugi Summons " Winged Dragon , Guardian of the Fortress " .
