By default, every C-rank Border member wears a white uniform. But Kuga wears black. Is there some reason behind this distinction?
The uniform is patched with the Tamakoma branch's insignia, so it should be a new one.
At first I thought it was because of the black trigger, but he is not listed as an S-rank, and its a key plot point that he keeps his black trigger "apart" from his Border assignments (so far).
