Sakura 5 (theme-music box ver.)

 is a track in Xenosaga Episode II. It has not been released on any soundtrack or sound selection and not much is known about this track. The track is a remix of Sakura (theme-piano ver.), and as such its melody is based upon that of the Xenosaga II opening theme (and, by extension, of Sweet Song (Xenosaga II ending theme)).

It plays in the cutscene where Kevin and Shion talk about their hopes for KOS-MOS's future (flashback) (English audio only — in the Japanese version of the game, plays instead).
