Unfortunately , there is no other way out , so the power is cut . Isono and the officers are shocked then , when even that fails . The shadowed figure from before , a long haired man in expensive clothes , appears next to Isono , commenting that he ' s a little too late . As guards appear behind the man , who is present as a hologram , he declares that Kaiba Corporation now belongs to the Asian division of Industrial Illusions , and remarks on the Duel Ring server , and how his master strived for it - now it ' s his .

Yugi accepts and everybody rushes up . Yako says that it is time to Duel but Yugi states that Yako is not really there causing Jonouchi to freak out even more . Yako congratulates Yugi for realizing this and tells everybody that this is not his actual body but a projection created by Kaiba ' s solid vision system . He then forces the beginning of the Duel , stating that as the Duel King , Yugi cannot maintain his title without accepting challenges . He adds that the card he holds won ' t let Yugi off easily either , claiming it to be invincible .
