The opening of Trigun is pretty unique because of its lack of lyrics. Despite that, it’s an extremely catching and fun song to listen to. The opening itself features mostly establishing shots of the characters and the setting, although there are different versions of the opening that correspond to each episode by showing some footage from it. That could almost count as spoilers, but without context it can’t really spoil much, and if anything I found myself excited to meet the new characters and villains that Vash would have throughout the show.
