Okay.. so Ragna's Nox being a time paradox, it is counted out of the ten created. What I'd like to know is how Jin, despite the weapon being taken care of by Jubei, who's location was not public knowledge, recognized the sword as a Nox. (I take this from Calamity Trigger, when he states that he didn't know Ragna had the capacity to use one. Sorry, too lazy to quote it. =w=)
