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 returns from being an unwilling subject of DOATEC's bio-weapon experiment Epsilon left to die in the esoteric Black forest of Germany as "Ein" after the experiment was a failure.
