Sometimes Muramasa gets too angry. What caused her anger this time? It's not completely known. Perhaps Inferno accidentally looked at another girl and she got jealous. Perhaps Inferno made a bad joke. Or maybe Muramasa just got off on the wrong foot and decided to rip Inferno's other arm off. She loves him of course, but in a very strange and not typical love:3 Inferno is scared, not because he's afraid of Muramasa, but because he won't fight back. He'll have to endure the beatings and wait for her to calm down.
