Es ist das Aerith Theme mit Text. Es ist auf der Suteki Na De Single neben "suteki na de" + instrumental und The Moon(hat nix mit FF zu tun, ist ein Lied von Rikki) drauf.

Hier die Lyrics:

Pure Heart (Aerith’s Theme) English Lyrics
****************************************
Straight on this long, continuing road
There is surely something to believe in

Like a traveler in the midst of the wind
I have my eyes on the northern sky

The passionate feelings that were beginning to vanish
Once again sway in radiance in my chest

I don't want the tears to spill
As so not to lose to my weaker self

In eyes holding only an unadorned spirit
There are great, unseen wings
I open my arms while singing
To embrace the perpetuity of time
To be tied to life

Straight on this long, continuing road
There is surely something to believe in
