I agree it was too early and unexpected for Sternritter W to appear, but it's about time that one of the three unknown Sternritters finally revealed themselves. I've been waiting forever to find out who are the last three Sternritters that still haven't appeared are.

With that said, there are now two more unknown Sternritters.
