Under the sad end-of-days spell of the smoky dusk and the waning year, of the moon and its ostentatious superiority to the trashy, petty claptrap of his sublunar existence, why does he even hesitate? The Kamizakis are your enemies whether you do or not, so you might as well do it. Yes, yes, if you can still do something, you must do it - that is the golden rule of sublunar existence, whether you are a worm cut in two or a man with a prostate like a billiard ball. If you can still do something, then you must do it! Anything living can figure that out.
