Kasumi (かすみ) is the main protagonist of the Dead or Alive franchise created by Tomonobu Itagaki and Koei-Tecmo's Team Ninja Development team.
About[]
The second child of Shiden and Ayame, Kasumi is Hayate's younger sister and was second-in-line for the right to inherit leadership of the Mugen Tenshinryu (霧幻天神流 Misty Phantom Celestial Spirit School) as an heir to the Tenjin Faction of the clan. Trained as a kunoichi by her father, she enjoyed an ideal childhood with her brother Hayate, the clan's heir, and was the best friend of Ayane, the outcast child of the clan.
One day, her brother was attacked by Raidou, a crazed exiled shinobi obsessed with power. Raidou nearly murdered Hayate when he stole the clan's best kept secret art; Rekku Jinpusatsu (裂空陣風殺 Fatal Wind Sky Fissure) from him, leaving him in a comatose state he seemed doomed to remain in. Her father Shiden was left embittered by the loss of his son and refused to tell Kasumi about what happened to her brother. When she found out the truth, Kasumi, driven by the desire to avenge her brother, abandoned the village. In doing so she left the clan as a renegade and was declared a threat to their safety, leaving the clan no choice but to send their best to find her and capture her, or in Ayane's case kill her, so the clan would be safe from the outside world. Her brother's best friend, Ryu Hayabusa of the Hayabusa Ninja Clan, would act as a surrogate guardian in the event something befell Hayate.
Although she succeeded in getting her revenge against Raidou in the Dead or Alive Marital Arts Championship hosted by Fame Douglas, Kasumi would be captured by the Dead or Alive Tournament Executive Committee's Superhuman Development project and used as a lab-rat for Project Alpha, where her DNA was subjected to cloning. Now on the run from both her clan and her newly restored brother, Kasumi must not only elude DOATEC's minions but most also survive against her own clan's top assassins. When she learns of her clones being converted into weapons of mass destruction Kasumi sets out to find Victor Dononvan, the instigator of DOATEC's amoral acts, and end him before he and his MIST organization can do more harm.
