Plot synopsis:
Dead or Alive: Dimensions plot spans the first four main games in the Dead or Alive series. In the prologue, set before the first game, Kasumi is confronted by her father and current leader of the Mugen Tenshin ninja clan, Shiden, about her skills as he plans to make her his next heir. Later, the exiled ninja Raidou attacks the village, beating Ayane and defeating Hayate, who falls into a coma. Upon learning this, Kasumi decided to run away from the village to take revenge on Raidou for Hayate, even though it meant she would be a fugitive and likely to be killed by her own clan. Kasumi is quickly stopped by Ayane, who was order to track her down and kill her, but Christie appears in a helicopter and saves Kasumi. Although Kasumi did not know the woman, she went with Christie to safety. Heading towards Helena Douglas' cruise ship Freedom Survivor, Kasumi is introduced to both Christie and Bayman and is told about the DOA tournament, with Raidou being there. Kasumi encounters Ayane, now a contestant, and both meet Raidou with Fame Douglas, the head of the Dead or Alive Tournament Executive Committee (DOATEC). After Kasumi fights her way and manages to reach the final round, she faces against Raidou and defeats him, but then he reawakens more powerful than before. Kasumi uses her magic against him, and with help from Ryu Hayabusa, she finally kills Raidou. However, she gets kidnapped by DOATEC, which prompts Ryu to save her. That same night, Douglas is assassinated by Bayman under the order of Victor Donovan, and although he is successful, Christie leaves him behind as she returns to DOATEC headquarters.
Hayate, still in a coma, is abducted from the village by Kasumi Alpha. Ayane is told by Genra about the return of Tengu and sent to search for Ryu in Europe. After the death of her father Fame, and her mother Maria, Helena appears on Freedom Survivor and takes over the Dead or Alive Tournament Executive Committee and announces the second DOA tournament, with herself participating as a competitor. Ryu hears that Kasumi is in DOATEC Germany and goes there. In DOATEC's facility in Germany, where Kasumi is indeed being held, Alpha sneaks Kasumi out of her cell. As the facility burns down, Ryu saves Kasumi and takes her to safety, while Lisa Hamilton and Alpha make their escape with Hayate and place him in one of the helicopters, which gets hit and crashes. In the forest, Ryu and his friend, Irene Lew, learn that Hayate was human experimented on in genetics research in the facality and Kasumi runs off to find him. In another part of the forest, Hitomi is training when Hayate, who survived the crash, stumbles into her and collapses. As he battles through the tournament, Ryu encounters Hayate, who is now going by the name of "Ein" and suffering from amnesia. Later, Ryu tracks down Tengu and kills him. Ein arrives at Miyama and tries to remember why he knows the place. After defeating Kasumi in battle and knocking her out, Hayate regained his memories, but Genra reveals that he allowed Tengu to pass into the human world and escapes, leaving a brainwashed Ayane and Kasumi Alpha to fight Ryu and Hayate. Ryu, along with Irene, explain to Hayate that Genra may have been involved with DOATEC, and although Ayane returns to normal, both Kasumi and Alpha disappear.
During the third tournament, Helena hires Bayman to protect her and kill Donovan. Christie, posing as Helena's assistant, attempts to assassinate her but is caught and restrained by Bayman. Alpha over-hears that Helena wants Donovan dead and attacks her, but Helena manages to defeat her. With Genra turned traitor, Hayate requests to his father that he should hunt him down, making Shiden believe Hayate is ready to take over as the leader of the clan instead of Kasumi. Hayate wants to bring Kasumi home first, but Ayane speaks against it, calling Kasumi a traitor, which enrages Hayate and makes him slap her. Thinking that Hayate now hates her, Ayane attempts suicide, but is found by her mother, Ayame. Ayane is upset believing Hayate only cares about Kasumi, but Ayame reminded her that all four of them are family and asks Ayane to save Kasumi. Hayate and Ayane join the third tournament to track down Genra. While on Freedom Survivour, Hayate meets up Hitomi again since his departure when he was Ein, and Hayate tells Hitomi the truth about his ninja identity, much to her surprise. During the tournament, Hayate meets with Helena, who recognises him as the subject of Project Epsilon. Hayate demands she tells him why Genra joined DOATEC, but she claimed she does not know and both Genra and herself are just puppets of DOATEC. After defeating Helena in battle, he tells her that she should leave DOATEC. Later, Hayate and Ayane meet up with Ryu and Irene, but Irene gets kidnapped by Christie. Ryu runs off to save her, while Hayate and Ayane are confronted by Genra, who he transformed into his Omega form. When Ryu realises that Christie was just a decoy, he returns to aid them, and runs Genra through with his Dragon Sword, giving time for Ayane and Hayate to perform a duel magic attack that strikes Genra before he could regenerate, killing him. When they return to the village, Ayane watches Genra's body cremated as she walks away in tears.
After Helena became head leader of DOATEC, Donovan discusses with her the biological weapon cloning project, Project Alpha. With the fourth tournament on the way, Hayate and his clan are planning an attack on DOATEC's main headquarters, the TriTower. Fearing the worst, Kasumi finds her brother and tries to convince him not to start a war, but the plea falls on deaf ears. One night, Hayate, Ayane, and Ryu attacks the TriTower with Irene and the CIA aiding them. At the same time, Kasumi infiltrates the TriTower and confronts Helena, pleading with her to stop, but Helena replied that the ninja would stop at nothing to destroy DOATEC, and the final product of Project Alpha, Alpha-152. Helena attempts to shoot Kasumi, who is saved by Ryu. While Kasumi makes her way to fight an awakened Alpha-152, Hayate and Ayane use their magic to destroy the TriTower, only to have to face Alpha-152 themselves. With the TriTower in flames, Helena faces Christie one last time, and learns that it was actually her who killed Maria. After finding out the truth, Helena sets of the building's self-destruction and plans to end her own life, with Kasumi and Ayane watching from afar. However, she is saved by Zack, who sweeps in by helicopter and pulls her to safety. The final scene shows Donovan taking off his white mask, and putting on Genra's mask.
