If Ryu was correct, it was likely only that Black Thunder Wraith, Wunikai and one other he had a memory of that could do so.
This still wasn't enough, in Ryu's opinion. These three were excellent talents, but they still weren't considered to be the true monsters of the Demon Kings. Those would be existences like his wife and others who didn't even show up today.
But it was a decent start.
As for what would make Ryu satisfied?
Well, he had not a single care in the world for the standards of the True Martial World.
