S-Rank weapons

[spyder101]

Hey, just a quick question i had....
Why is it that on pictures for some of the s-rank weapons, like the s-rank blade, it has NAUSICAA as the name, and for the pictures TSFO-SnaPPLE took all the s-ranks he has have SNAPPURU as the name?
(i know this may sound like a confusing question)

I dont know much about s-rank weapons, seeing how i am not online with pso, but i was wondering if the s-rank weapons names were all random, or is it possible to change the name of them, or....anything else...?

You name them yourself.
