Accepted. I think we found our gun-nut~, although, just to make sure; All of that's at his house, securely locked up, right? And disassembled, right? 'Cuz one thing that I think was hinted at in the anime, and is super strict IRL, is that Japan is super butt-tight with firearms. I don't think he could have that stuff in his house, assembled, along with being a foreigner, without some cop rushing in with a baton and wooping him over the head.
Oh, just read it. Apparently it's super locked up tight. I'll accept that.
