Introduction (Japanese:イントロダクション)[1] is a song used in Wild Arms Alter Code: F in the first scene of the prologue where the heroes Rudy Roughknight, Cecilia Adlehyde and Jack Van Burace are all walking together and reuniting with their comrades, seeming at the end of their journey. The song contains parts of Windward Birds and Into the Wilderness in its melody. A piano-only rendition was recorded for the Greatest Hits album Music the Best -feeling wind-.
