Jr's Promise

 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. Part of its melody is also used in Thoughts with Ziggy.

It plays in the cutscene when Jr. promises to MOMO that he will return from confronting Albedo alone (Japanese audio only — in the English version of the game, Sakura (theme-piano ver.) plays instead).
