[@Sedjwick]: I mean, I was asking you for something to work with backstory wise, and saying that he doesn't know doesn't really help very much. I think you still need to do some work here.

You could also work that into his personality for a little more depth, rather then just lacking allegiance giving him a reason he doesn't trust either government.

I think you underpowered his limit break a lot too, since that's a fairly basic function of any magitech weaponry, infusing magic into your weapon. Speaking of which, a basic shortsword is also a bit minimal even to start with, and I'd suggest trying to make it a little more elaborate to suit the setting.
