Hey, same like me. [Rokurou can't help but grin at the mention of katanas. True, he doesn't wield formal katanas, but the blades he does use are within the same family. That and he has practiced with them before so he's at least familiar with the style.]

I'm sure there's a weapon shop or a swordsmith that sells them. Was actually planning on scouting a few places to see if I can get myself some normal blades.
