What are the badges that Ryou wears? In Code Geass: Akito the Exiled, the character Ryou wears five colored badges on his outfit.



His article on the Code Geass Wiki says nothing about this. What do these badges signify?
Here are images of the badges that I believe are clearer (taken from blogsuki.com):


So, what do we see?


A rising Sun, a traditional motif for Japan;
An 'R';
A mask with two colored halves, smiling;
A geometric pattern;
A yellow-green thing that I do not even know what that is;


Apart from the rising Sun, and maybe the 'R' could stand for Ryou, I do not really have an idea of what these symbols would mean.
