Dead or Alive 2 - Kasumi

Fame Douglas, founder and CEO of DOATEC was killed at the end of the 20th century. He was renowned as the sponsor of the legendary Dead or Alive World Combat Championship. After his death, the world began to become chaotic. In the middle of the chaos, it was announced that the second Dead or Alive World Combat Championship will be held.

The purpose and significance of the tournament changed after Douglas' death. The promoter of the second Dead or Alive Championship, who is fond of conflicts and jealous of the strong, is responsible for Douglas's death. The new promoter, Victor Donovan, is more than a corrupt mastermind, but a man of pure evil. His involvement in the tournament began to bring a sense of terror to the world, resulting in the infamous tengu disaster.

Set less than a year later after the original tournament, a tengu known as Gohyakumine Bankotsubo, or just Tengu, escapes from the tengu world and threatens the human world's peace and stability. Kasumi, who won the first tournament was captured by the DOATEC Super-human Development project. Kasumi escapes, but her clone "Kasumi X" was created while she was being held captive. Kasumi's brother Hayate, previously injured by Raidou, was also captured and was unwilling used as a subject of DOATEC's bio-weapon experiment Epsilon. He was later left to die in the esoteric Black forest of Germany after the experiment became a failure.

Ryu Hayabusa (from Ninja Gaiden) enters the tournament vowing to seek and destroy the evil tengu. Though a dangerous, suicidal task for any ordinary man, Hayabusa owes it to himself and to mankind to confront his fate. Hayabusa tries to warn other competitors like Jann Lee about the dangers of the tournament but finds them unwilling to backdown so he proceeds to knock them out of the tournament. He meets a competitor named Ein, who is actually the missing Hayate suffering from amnesia. During their fight, Hayabusa defeats him and restores some semblance of his memory. Eventually, Hayabusa comes face to face with the evil Tengu. He defeats and kills Tengu, winning the tournament.
