At the Domino City museum, Yami Yuugi encounters Ishizu who tells him that for 3,000 years her tribe has been protecting the Pharaoh's memories. In order to regain his memories, Yami Yuugi must gather the 7 Millennium items, one of which will appear in an upcoming battle Ishizu could see through her Millennium Tauk. Before leaving the rest for Yami Yuugi to confirm with his own eye, she adds that the Pharaoh's battle is for the sake of gaining his memories back and that his fate will be set in motion soon enough. That night, Kaiba announces the Battle City tournament which will commence in a week, where everyone must use his new duel disk system and bet their rarest card in each duel. (Source: Yu-Gi-Oh!
