Wii Would You Wear This Muramasa: The Demon Blade T-Shirt Outside? By Siliconera Staff September 15, 2009 ShareTweetPinShare 0 Two points to consider: 1.) It’s based off Play Magazine’s risque Muramasa: The Demon Blade cover. 2.) It’s size XL. Ignition sent one of these shirts over to us so it’s probably some kind of collectable. I suppose that’s a third point to cogitate about too.
