U-DO~Febronia

U-DO~Febronia is Disc 2, Track 3 on the Xenosaga II: Jenseits von Gut und Böse ~Movie Scene Soundtrack~ and Track 1 on the Xenosaga Episode II: Jenseits von Gut und Bose Soundtrack. It is a combination of two pieces of music: 'U-DO', which plays at the start and 1:58 in the track, and 'Febronia' (not to be confused with from the Xenosaga III: Also Sprach Zarathustra Original Sound Best Tracks), which plays from 0:56 to 1:58. U-DO uses as its main melody a motif from first meeting.

The entire track plays in the cutscene where Shion breaks down over KOS-MOS needing to kill Cecily and Cathe. The U-DO sections of the track also play when Jr. activates Red Dragon mode against Albedo in the Space-Time Anomaly.
