Genji guessed that they wouldn't have real weapons if they were regular people. After all there were the gun and knife laws and all of those other things. Plus Genji figured it was good that, as regular people, that they didn't have weapons. "Well you should have a weapon anyway. While I support fighting with your fists, having a proper weapon at your side can help you out alot. Anyway, ill be right back. Ill go see what we have that I can give you, and don't worry about paying for them. These are free. So sit tight and just make yourselves at home." 

After that Genji left, leaving Silas and Sasha to their own devices for a bit to talk or do whatever. In about ten minutes though he returned, a large, cloth wrapped bundle in his arms. "Alright, I'm back. I found these, pick whichever weapons you like, and I know that you have other friends as well, so you can also pick some things from here for them if you know what'd they want."

In the bundle there were a few daggers, a couple of short swords, two long swords, a katana, a real bow and arrow, and a spear. They all looked very real and quite well crafted, as would be expected by practitioners of martial arts.
