The King of Fighters

At a museum in Boston, Rugal Bernstein steals three relics: The Kagura Mirror, the Yagami Necklace and the Kusanagi Sword. He uses them to disappear into a dimensional portal to awaken the mythical entity known as the Orochi, which grants limitless powers. The sword is revealed to be a fake and the quest is delayed. Mai Shiranui is told by an injured Chizuru Kagura the real sword is with Saisyu Kusanagi at a mental institution. She is warned she must defeat Rugal and her boyfriend, Iori Yagami, should not be involved. At the institution, Mai meets a catatonic Saisyu and his son, Kyo, but Iori's presence suddenly breaks Saisyu's catatonic state, and the elder Kusanagi threatens to kill Iori before losing consciousness and dying.
