She was communications officer for the USS Enterprise.
Mirror Universemirror universe, Hoshi was the "captain's woman" to Captain Forrest, the captain of the ISS Enterprise. She took advantage of circumstances when the alternate Jonathan Archer, the first officer of the Enterprise, obtained the USS Defiant from the normal timeline, which had fallen into the mirror universe.
Archer hoped to use the Defiant to dominate the Empire, but Hoshi assassinated him after he recovered the futuristic starship and used it to declare herself Empress (ENT "In a Mirror, Darkly").
