What does Saisyu Kusanagi have?
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.
At another hospital, Chizuru is recovering from her injury and is informed by her colleague, Scott, that Rugal has altered the King of Fighters database and issued challenges to fighters around the world. CIA agent Terry Bogard enters Chizuru's room, demanding information on Rugal's whereabouts and the tournament. She tells that different dimensions exist, but he does not believe. Chizuru tells Terry to go to Seattle and ask Mai, who is an undercover operative sent by the CIA to infiltrate Chizuru's organization a year ago.
At a cemetery in Seattle, where Saisyu is buried, Kyo and Iori confront each other. Iori explains that both Kusanagi and Yagami clans were destined to be enemies. Mai hitches a ride with Kyo to his home, where she explains that she is looking for the Kusanagi Sword. Kyo tells her that centuries ago, a Yagami ancestor attempted to release the Orochi, but it consumed him with murderous rage. Kyo's ancestor killed the Yagami and returned the Orochi into its world. Mai tells Kyo that Rugal is out to unleash the Orochi. Kyo wants to confront Rugal, who destroyed his father's mental state.
