during the second tournament, Nina was awoken 19 years later by the influence of the recently excavated Ogre, who compelled her to assassinate Jin Kazama. As per her request, Anna was awoken at the same time as her sister, though she was unaffected by Ogre's influence. Nina also began to suffer ill effects from the 'cold-sleep', resulting in long-term memory loss. In an act of compassion, Anna set out to stop Nina from once again becoming an assassin, and to help her recover her memory loss. However, she failed at the end of the tournament when Nina recovered her memory about her rivalry with Anna, which resulted in Nina leaving and cutting all contact with Anna. In Tekken 4, it was confirmed that Anna makes a cameo appearance in Nina's prologue. She was mentioned by the game's unused files. Anna is absent in Tekken 4, though she is briefly mentioned in Nina's Tekken 4 prologue. In Tekken 5, Nina decides to make contact with Anna in hopes of restoring her memory, but their meeting triggers Nina's lost feelings of hostility towards her sister, and she immediately opens fire. Anna retaliates, and the reunion descends into a gunfight which lasts for days. The sisters eventually reach a stalemate and agree to settle things for good and a portion of their battle can be seen in the introductory sequence of the game. During their battle in the tournament, both sisters agreed that only one would walk away from their battle alive. However, when Nina defeats Anna, she refuses to take Anna's life as she felt the fight was not satisfactory. Humiliated by her loss, Anna seeks revenge at Nina, who has already gone into hiding. Anna hears rumors she has become Jin's new bodyguard, thus being involved with the Mishima Zaibatsu. In another attempt to have a chance to battle Nina, she offers herself as a personal bodyguard to the CEO of G Corporation, Kazuya Mishima, knowing that his plan to confront Jin would eventually lead her to her sister. She enters The King of Iron Fist Tournament 6 at Kazuya's request. In Scenario Campaign, Anna leads the defense of G Corporation against Mishima Zaibatsu and Lars Alexandersson's rebel army, and during a confrontation with the rebel army, she sends troops that results in Lars' friend, Tougou's death. She also accompanies Kazuya when he comes to Azazel's Temple in the desert. Upon
