(A/N Anyone who knows vanguard agrees this has to be on the list at least once for an opening list, the opening that started it all and got you into the show ^_^)

I won't tag but those who know vanguard I would recommend doing this cause its good to revisit the openings for the sake of a list like this. With that lets all continue to live in this golden age together
