When I link with my α-driver, 
I have wings of light.
عندما أرتبطُ بمحرّك الألفا الخاصّ بي
أحصلُ على جناحيّ النُّور
Wenn ich einen Link
mit einem α-Driver eingehe,
Al enlazar con mi α-driver,
tengo alas de luz.
Al enlazar con mi α-driver,
tengo alas de luz.
Quand je me lie
avec mon Alpha Driver,
Quando mi connetto con il mio Alpha-Driver,
ottengo un'ala fatta di luce.
Quando eu me ligo com meu 
alpha-driver, tenho asas de luz.
