It first aired in Japan on February 13 , 2008 . Summary . Atticus is glad to see that Yusuke Fujiwara is alive , as he has assumed he had died during his experiments . When asked why he did what he did , Yusuke replies that in the World of Darkness , there are no winners , no losers , no loneliness , no suffering - only a sense of unity . He says that all minds become one and all feelings are shared . He states that a person ' s dreams , the reality a person truly wishes for is what they will experience in the World of Darkness . Fujiwara appears to be fully under the control of Nightshroud ( in the Japanese version , Nightshroud ' s name was " Darkness " ) . Atticus is unconvinced , and the Duel continues . Fujiwara activates " Clear World " , and four crystals appear in the sky , which block out the landscape and all of the Trueman clones . Save for the Duelist s , only Jaden and Jesse remain . Fujiwara reveals that " Clear World " forces both players to deal with a different negative effect depending on the attribute s of the monsters they have face - up . " Red - Eyes Black Dragon " is a DARK - attribute monster , and the player cannot declare an attack with a monster of that attribute face - up while " Clear World " is active . Fujiwara states that both attributes and personality are unneeded things in the the World of Darkness . He then activates " Clear Sacrifice " , removing the " Clear Phantom " and " Clear Rage Golem " in his Graveyard from play to Summon " Clear Vice Dragon " without Tribute . As " Clear " monsters have no attribute through their own effects , so Fujiwara is unaffected by " Clear World " . Atticus declares all of Fujiwara ' s musings to be " nonsense " and states that he is simply ignorant of unlimited potential of humankind . In order to help Atticus see more clearly , Fujiwara allows him to again witness what his friends are experiencing in the World of Darkness .

Fed up with the situation , Chazz instead draws the second card from the top of his Deck and Summons it - " Masked Dragon " . However , he immediately finds himself back in his last Pro League match , and is immediately disqualified for his actions . He is then engulfed in waves of darkness , finally accepting his fate . Syrus is still attempting to build a " Cyber Style Pro League " with his brother , but cannot carry the weight . He informs his brother , who crumbles to dust as Syrus is engulfed in waves of darkness , he too , accepting his fate . Alexis is failing as a teacher , and after encountering clones of herself who deride her efforts , accepts her fate and is engulfed in the black waves . In doing so , the three are essentially erased from existence as they are assimilated in the World of Darkness itself .
