Shadi tells Ishizu and Marik that blood will spill upon blood , and tragedy would tear their clan apart . He explains that this is the will of the Pharaoh . Shadi turns and walks away , with Ishizu asking him who he is , but Shadi disappears as abruptly as he ' d arrived . Marik ponders Shadi ' s words in surprise . In the present day , Shizuka , Jonouchi , and Yugi listen in shock to Ishizu ' s tale . Yugi realizes that she ' s talking about Shadi . Dark Yugi muses that Pegasus saw Shadi too . It seems Shadi appears before everyone who is tied to the Millennium Item s . He thinks that Shadi is the answer to all their mysteries , Shadi knows everything . Ishizu continues , stating that for exposing Marik to the outside world , and thus breaking the law of the clan , their family was set on the road to destruction . She closes her eyes and continues her tale . Marik and Ishizu searched the town , but were unable to find any sign of Shadi . Marik wonders where Shadi went , asking Ishizu if she saw Shadi too , pointing out that the ankh around his neck looked a lot like the Rod and Tauk their family keeps secret . Ishizu interrupts him , warning him to never speak of what he saw in this world , telling him to just forget today ever happened , forget everything he saw , including that man . Marik reluctantly agrees , but he begs Ishizu to let him keep the picture of the motorcycle . Ishizu just tells Marik , " let ' s go . " She thinks that Shadi knew they were Tomb Guardians , and without a doubt , his ankh was a Millennium Item . She wonders who Shadi was . The siblings arrive back at the entrance to the underground . Marik sadly thinks that once they ' re back underground , they ' ll be back in the darkness , with nothing but the light of candles and lamps . Ishizu opens the doors , telling Marik that she ' ll go first and he ' ll follow quietly . Marik looks at the sun , and asks Ishizu to wait just a second . He looks at the picture of the motorcycle , and sits on a wall fragment , miming the sound of the motorcycle . He wishes that he could ride around this great big land . Ishizu calls out to Marik , and he comes over , pocketing his picture . Then Ishizu sees something that horrifies her ; a contraption on the back of the door . She didn ' t notice it in the dark , and the rope leads all the way down along the wall . Marik hasn ' t noticed , and he asks his sister what ' s wrong . She realizes that their father set a trap so he would know if they disobeyed him . Then she suddenly realizes , " Rishid ! " Ishizu runs down the stairs , and Marik follows , asking what ' s going on . Ishizu mentally begs her father to forgive them , and they reach Marik ' s room . The books are scattered messily on the ground , the blankets are torn , and Rishid is gone . Marik runs along a corridor , and then he sees a candle - lit room , and looks inside to see Rishid , tied by his wrists to a pillar , on his hands and knees with his robes torn open and bloody scars covering his back . Ishtar stands behind Rishid with a red - hot sword in his hand . Rishid , hearing Marik call his name , begs his master to stay away . Ishtar turns and sees his children as Marik yells " father ! " He warns them that they ' ve broken the law of their clan , and he re - heats his sword in a basket of coals , telling them that he ' ll give them their punishment later , but first , he address Rishid . He asks if Rishid forgot the debt he owes them for picking him up off the streets . Could Rishid not even fulfill his duties as a servant , and as Marik ' s keeper . Sweating , Rishid apologizes . Ishtar warns Rishid that this will cost him his life . Marik begs his father to stop and grabs his free arm , but Ishtar , caught up in his bloodlust , swings his arm and throws Marik into the wall . Ishizu rushes over to him in concern , as Ishtar tells them to take a good look at the pain they gave him , and smiles cruelly as he digs the blade of the sword into Rishid ' s back . Rishid screams in agony , and Ishtar sneers , telling him to die . Rishid falls to the ground as Marik screams his name . Ishtar turns to Marik , telling him that it ' s his turn . In that instant , something strikes Marik , and he clutches his head in his hands , much to the confusion of his sister and father . The top layer of his hair spikes up , and he adopts a fierce look before laughing , thanking his father for killing Rishid . The Eye of Wdjat glows on his forehead for the first time , and his father yells at him . Dark Marik points the Rod at Ishtar , blasting him into the wall . Ishtar struggles , realizing that he can ' t move . Ishizu speaks up , asking her brother what he ' s doing , but Dark Marik tells her to stay out of this , freezing her with the Rod ' s power , and turning to Ishtar , telling his father that he ' ll be the first to die . Ishtar weakly begs him to stop as Dark Marik laughs , unsheathing the Rod ' s dagger . Ishizu yells at Marik to stop , before realizing that this isn ' t Marik , it can ' t be . She averts her eyes . Ishtar ' s screams of agony echo through the underground , as his shadow is shown tied to the wall by his wrists , while Dark Marik ' s shadow has its arms raised above his head . Dark Marik then approaches Rishid , holding a bloody rectangle , commenting that Rishid wanted proof of belonging to the Ishtar family , didn ' t he ? He throws the object onto his back , his robes stained with blood , and tells Rishid to take this to the netherworld - Dark Marik has cut off the portion of skin with Ishtar ' s own scar on it . Rishid shifts ; he ' s still alive . Dark Marik freaks , angrily raising the Rod and asking why won ' t Rishid just stay dead . Rishid whispers his master ' s name , and Dark Marik drops the Rod and falls to his knees , returning to normal and looking at his bloodstained hands in confusion . He asks what happened to him and he turns , despite Rishid ' s protests . He sees Ishtar ' s lifeless , mutilated body , and tears form in his eyes as he screams " father ! " He embraces his father ' s body , while Rishid and Ishizu watch on , furiously asking who did this to Ishtar . Ishtar ' s earring falls off , and the sound alerts Marik just in time to see Shadi appear in front of him . Shadi explains that it was the soul of the Pharaoh that drove Ishtar to his death , and a confused Marik repeats the words in a furious daze . Production History .
