Yumi appears captive alongside Mari in Violence Jack 2. Her distinctive orange and yellow hair and green lipstick visually signal her untrustworthy nature. After escaping kidnappers transporting her to a sex slave operation, she hides with Mari in an abandoned building. Violence Jack intervenes briefly, killing their pursuers, but both women face recapture shortly after. They are taken to Captain Bomber's crumbling high-rise stronghold, where the sadistic dominatrix Rose oversees their torture and degradation. Rose specifically targets Yumi for breaking, subjecting her to whipping with a thorny whip, rape, and forced participation in lesbian acts. During captivity, Mari's lover Kenichi arranges their escape through a deal with Bomber. Yumi flees the complex alongside Mari and Kenichi, though her ultimate fate remains undocumented beyond this escape attempt.
