Kudoh is one of the top members of ES.W.A.T. He participates in some training sessions with Deunan and eventually earns her respect. When she and Briareos head to Dr. Gilliam Knute's old lab, Kudoh comes along. After they are betrayed by fellow ES.W.A.T. member Leyton, who is sympathetic towards the O.R.A., Kudoh stays behind, keeping his gun trained on Hades so that Deunan and Briareos can escape.

Shortly after this, Kudoh is gunned down by numerous O.R.A. soldiers and collapses dead against the wall of a hallway. Deunan expresses great distress over his death, but Briareos drags her away reluctantly, the O.R.A. hot on their trail
