Compare "Sunset of Seven Suns" 00:00–00:15, which is a variation of the Six Flowers motif, with "Running Sky" 00:00–00:26 (and other parts).
While the Six Flowers melody has been varied so much it becomes kind of unrecognizable, it should still be safe to say "Running Sky" contains the Six Flowers leitmotif? Or at least a variation of it?
