Why is Kusari called Kusari?

[Marcus Lindberg]

I mean, I can understand why Bretonia is called Bretonia, its a play on the word Britain.

Liberty is well, a play on the ideals of America.

Rheinland is simply a (deliberate) mispelling of the german territory called Rhineland.

Hispania...not to sure, but I think thats also a play on the country Spain (and probably one of Columbus's ships too, but not sure)

Gallia is a play on the word Gaul, which is what France used to be called before it was called France.

But....Kusari? And the Molly's?

I tried to go find out what these words meant and all, but alas my research skills are fail.

So I come to you discovery, why are they called what they are called?
