Biography . History . E ' Rah fed off the heartbreak suffered by Dr . Faker when he opened the door to the Astral World and she had a hand in the loss of Haruto Tenjo ' s soul . When Kazuma Tsukumo opened the door to the Astral World E ' Rah learned that the Astral World were sending a messenger , Astral , to confront her and as a result when Astral arrived on Earth E ' Rah scattered his memories and used them . Six months prior to the Numbers War , E ' Rah encountered the disillusioned Kyoji Yagumo before he was about to enter a tournament and gave him the nine " Number s " she had acquired and gifting him with him several supernatural abilities . Her possession caused Yagumo to desire the destruction of both Earth and the Astral World and to believe that their existence had no value . Yu - Gi - Oh ! ZEXAL . During the 3 vs . 1 Duel between Yuma Tsukumo , Ryoga Kamishiro , Kaito Tenjo and Kyoji Yagumo , when Kyoji was about to lose , E ' Rah appeared and took over him to continue the Duel , confronting her enemies for the first time .

But in reality , she was sealed inside Astral , whose mission demands of him to seal himself in a state of complete stasis for eternity , to make sure she could never escape again . Number Hunting . Prior to the events of the manga , E ' Rah came into possession of " " and 8 other blank " Number " cards . All of these were passed onto Kyoji Yagumo six months prior to the Numbers War . Deck . E ' Rah runs a Strain / Anti Deck , which creates " shadows " of her opponents ' monsters stronger than their original counterparts , reflecting her belief that light will always produce shadow , and the shadows will always be stronger than the light . Said monsters are called " E ' Rah Monster s " ; in Japanese , " E ' Rah " has the same pronunciation as " error " , so her shadow monsters can be understood as " error " monsters . In a pinch , E ' Rah can use the effect of " Strain Endo " to summon multiple " Anti " monsters , which she then layers to summon " Anti - Hope , God of Despair " . Some of her Spells refer to three of the elements of the ancient priests who opposed her : land , sea and sky . Her " Anti " monsters also follow this aesthetic , with allusions to all the elements , including light .
