Fuchida is a police officer on New Sydney who rescues Miles O'Brien from a beating and refuses to believe that the Orion Syndicate killed Morica Bilby.
Lieutenant Fuchida appears in the seventh-season episode Prodigal Daughter. He is a member of the police on New Sydney, in the Sappora system, where the Tigan family runs its mining business and where O'Brien has gone looking for the missing widow of Liam Bilby.
He brings O'Brien to the Tigan house after finding him being worked over by Nausicaans, and makes plain that he has little patience with an off-world engineer conducting a private investigation. Once Morica Bilby's body is found he treats the death as an accident.
O'Brien insists that the Orion Syndicate was behind it. Fuchida replies that the Syndicate looks after the families of its dead and would never murder one of their widows, a point that turns suspicion towards the Tigans themselves.
