Yu - Gi - Oh ! Duelist - Duel 156 The Proof of the Clan ! , also known as " Witness of the Clan ! ! " in the Japanese version , is the 156th chapter of the Yu - Gi - Oh ! Duelist manga and the 215th chapter of Yu - Gi - Oh ! in the Japanese version . The " Mystical Beast of Selket " continues to drive Jonouchi into a corner . Even though he ' s unable to fight back , Jonouchi has realised that Rishid isn ' t actually Marik , forcing the Tomb Guardians to take drastic measures . Summary . A satisfied Marik tells Rishid , his servant and shadow , to destroy all the enemies that stand in their way , ordering him to kill Jonouchi . Jonouchi is still hanging on with 50 Life Points compared to Rishid ' s 1600 . On the sidelines , Honda begs Jonouchi not to give up , and Mai wonders what Jonouchi can do . Jonouchi slowly draws , with only his " Baby Dragon " standing in the way of " Mystical Beast of Selket . " Rishid tells Jonouchi to give up his hopes of defeating him . Jonouchi looks at " Selket , " thinking that it grows stronger by absorbing the ATK of his monsters , already over 4000 . He doesn ' t have any cards that can stop it , his containing " Polymerization , " " Giltia the Dark Knight , " " Kunai with Chain , " and two unknown cards . Keeping " Baby Dragon " in Defense Position , he ends his turn . Rishid is surprised that Jonouchi insists on Dueling , despite the fact that he has no chance . Jonouchi replies that even if it ' s useless , he ' ll fight until his Life hits zero . Much to Jonouchi ' s shock , Rishid replies that he respects Jonouchi ' s spirit . Down below , Mai comforts Shizuka , then she turns to Yugi , pointing out that he know no matter how much friendship and perseverance a Duelist has in his heart , there ' s some times where you just can ' t win . And this Duel looks like one of them . Dark Yugi simply tells Mai to look at Jonouchi ' s eyes , and Mai is shocked , as Jonouchi tells " Marik " to bring it on . She observes that there ' s nothing Jonouchi can do , but his eyes still have a fighting spirit . Dark Yugi thinks that it ' s more than that ; those are the eyes of a Duelist recognizing a worthy opponent . Rishid declares his turn , attacking with " Selket , " which devours the struggling " Baby Dragon , " then stands fully erect as its ATK increases to 5225 . Rishid tells Jonouchi that it ' s his turn now ; his last turn . Jonouchi just passes , as there ' s nothing he can do , to the disappointment of Honda , Mai and Shizuka , though Dark Yugi remains impassive . Mai sadly thinks that it ' s all over . When " Selket " attacks on the next turn , Jonouchi is finished . Marik smiles , thinking that at this point , Jonouchi ' s chances are zero percent . He congratulates Rishid on winning . Jonouchi suddenly asks " What can you show , but you can ' t see ? " Rishid is surprised at the statement , and Jonouchi continues , he has a funny feeling . He can ' t explain it . A little while ago , he reached the point where he was resigned to losing , and just then , when winning or losing didn ' t matter , he saw something he couldn ' t see before . He wonders why he didn ' t figure it out sooner , deciding that it must have been the heat of battle . But then he remembered Yugi ' s words . What can you show , but can ' t see . Mai , on the sidelines , glances at Dark Yugi . Jonouchi states that Marik brainwashed him . He forced him to fight a Duel to the death , a pointless battle that only hurt him and Yugi ' s hearts . Yugi , in spirit form , watches from beside Dark Yugi , as Jonouchi yells that he ' ll never forgive Marik for that . Rishid closes his eyes , telling Jonouchi to go ahead and curse him , but still , no matter how great his anger , Jonouchi still cannot defeat him . Jonouchi continues talking : When the Duel started , he really hated " Marik , " he hated his guts , but as the Duel went on , he lost that hatred , and he tried to remember how bad it felt when Marik took over his mind . Marik realises what Jonouchi ' s saying , as Jonouchi states that Rishid is a true Duelist who fought him fair and square , so fair that Jonouchi lost those bad memories - because his opponent is not Marik . Dark Yugi muses on the enemy that you can show , but can ' t see , thinking that the true enemy is elsewhere . Kaiba , however , is more concerned that Rishid isn ' t the wielder of " Ra . " Dark Yugi explains that there ' s an obvious difference between " this man ' s " strategy and the Duelists who were brainwashed by Mairk . Yugi wonders where the real Mairk is . Dark Yugi wonders if there ' s an eight Duelist that they haven ' t seen yet , and then glances behind him , at " Namu , " the real Marik , wondering if it ' s him . To his credit , Marik remians impassive , thinking that if this goes on it will be inconvinient . Rishid tells Jonouchi that in a Duel , no - one listens to the words of a loser . Everything ends on this turn . He orders " Selket " the scorpion God to eat Jonouchi alive , and Jonouchi apologizes to Yugi . This is as far as he goes . But Marik tells Rishid to wait , and not to kill Jonouchi yet . " Selket " stops charging , as Marik tells Rishid that Jonouchi has to die " by the hand of " Ra . " " Rishid protests , but Marik tells him that to maintain their deception , he must demonstrate that he possesses the God card . Rishid " is " Marik , does he understand . He orders Rishid to Summon " Ra " from within the Ark in the Temple . The counterfeit God card , Rishid thinks . Marik reminds Rishid that if he ' s a true member of the clan of the Tomb Guardians , his heart will allow him to control the fake God card . Rishid ' s will is strong ; even though Marik ' s voice reaches him through the power of the Millennium Rod , he cannot brainwash him . That is proof that Rishid is a Tomb Guardian . Rishid still isn ' t sure , as he does not bear the blood of the clan , but Marik tells him that if he can control the counterfeit God card , his late father will accept him as his son . Rishid will be his heir as much as Marik himself is . Rishid remembers Ishtar telling him that he was just a servant , and he closes his eyes . Marik gently urges him to Summon " Ra , " that will be proof . And Rishid ' s eyes snap open . Dark Yugi wonders why he isn ' t attacking , but Rishid explains that for the last turn , he shall prove that he is the chosen one of " Ra . " Jonouchi repeats inwardly " The God card " Ra ? " " Dark Yugi himself is shocked , and Kaiba decides that Rishid is Marik , the possessor of " Ra . " Rishid reveals that right now , the God card is resting in the holy Ark . Though he must sacrifice " Mystical Beast of Selket " and half his Life Points to open the lid , when it is opened , " The Sun Dragon Ra " will be unleashed . Everyone on the sidelines gasps in shock as Rishid gives up half his Life , and " Selket " as well , chanting " Soul of the God which sleeps in the Ark , rise and show yourself ! " Marik smiles as Rishid calls " Come forth ! Sun Dragon Ra ! " The Ark opens , and a massive bird - like head wreathed in black flame , along with several fiery bolts , emerge from the Ark behind Rishid . Jonouchi observes the monster in horror , while Kaiba has a look of ecstasy on his face , and DarK Yugi thinks " I - It ' s real ! " Featured Duels : Katsuya Jonouchi vs . Rishid .
