Dead or Alive 2 is set less than a year later, as Tengu escapes from his world and threatens the human world. Fame Douglas, the founder and CEO of DOATEC was assassinated shortly after the first tournament, causing DOATEC to fall under a new leadership. Kasumi was kidnapped by DOATEC and was used as a subject in DOATEC's bio-weapon experiment, Alpha. Kasumi's brother Hayate, previously injured by Raidou, is also kidnapped and was used as a subject in DOATEC's bio-weapon experiment, Epsilon. New fighters include Ein, Helena Douglas, Kasumi Alpha, Leon, and Tengu. Eventually, Ryu Hayabusa defeats Tengu and wins the second tournament.
