It's actually another of Nasu pun or maybe Gen pun..

SIN is acronym of Synchronized Intellect Nation which literally what happen in this LB where education is banned for the people,, everyone is equally ignorant. but yes it's also a pun of Qin being pronounced almost like Sin, except I think in japanese they add small h between S and in.

so yeah the author thought why not make it spice it up a bit and change Qin to SIN and made it an acronym because Sin sounds cool right? RIGHT?!
