Uhm. Hi. =0

I started reading Trace a few days ago and I got to the 3th Volume the one about Jin & Rose and I was wondering if anybody knows what the URD (Jin always wears Cloths with that on) stands for... or if it has some sort of relation to an actual brand or something like that. I don't know. My own researching found me a page about borer but I don't think that's it. If someone has an better Idea please tell me.

I think I got the right Forum, otherwise I'm sorry.

Edit:
Alright. It explained it self.
