They don't need to be in the opening to appear. We saw it already, we had Cinder her team in the first opening and they showed up at the end of the volume, the White Fang wasn't there too, yet, they were at the final episodes. Adam was in the first opening but he wasn't even mentioned, basically, they don't need to appear to be there or even get a big role in the story.

The White Fang and Adam are confirmed for Volume 2. The White Fang logo was in the first wallpaper of Volume 2 when they announced it and Monty said that Adam is coming back even stronger than before.
