Ryu found using the bow without his eyes to be a fascinating sort of experience.
His grandfather had always said that the most important thing to an archer was their eyes. Suddenly finding himself without a pair, Ryu felt a subtle difference that he hadn't been able to grasp before. Even after several months, that feeling was still subtle, but bit by bit, he seemed to be getting closer and closer to exactly what that enigmatic feeling was.
Ryu didn't chase after this elusive feeling, though. Instead, he focused on other things, realizing that this wasn't something you chased after. The more effort he put into trying to understand it, the further out of his grasp it would grow.
So, he turned his attention to the subtleties of pulling on the Daos of the True Martial World.
