Foreigner's True Name is Mysterious Heroine XX (ナゾノヒロインXX, Nazo no Hiroin XX?), a version of Mysterious Heroine X from further in the future. She has taken up a job in the Servant Universe that involves hunting down Foreigners.
MHXX's Stage 1 appearance shows her in high-tech full body armor with flight capabilities. Stage 2 removes the helmet, revealing a woman underneath with most of the armor pieces intact. Stage 3 has all of the armor removed, instead wearing a two piece bathing suit, blue cap, and a small long sleeve blue shirt.
