Crux

Crux is one of the characters in Final Fantasy: Unlimited. A fairy marionette brought to life by Oscha, Crux's job is to spy on Kaze the Hayakawa twins Yu and Ai. She will then report her findings to Oscha or whichever of the Lords of Gaudium is around.

Crux's entire vocabulary is made up of "kukuruyu". Periodically abused by the Lords of Gaudium, Crux developed feelings on Makenshi when he saved her life. Crux rebelled against Oscha and helped the protagonists during the battle against Chaos Tyrant.

After the battle, Crux carried Makenshi away and tended to his wounds. She later becomes his traveling companion. Crux was damaged by Crux Number-2 when she found [Madoushi]]'s grave. Crux received a gem from Makenshi's older brother Madoushi, which contains Madoushi's entire power, from his grave. From this Makenshi learns the mist powers of his brother, and Crux is able to transform into a Cross Sword, combined with Makenshi's own sword.
