[Maybe it was a mistake by her, or a mistake by him, but the second Gintoki feels something on his arm he'll turn on a dime, fast -- maybe a bit too fast, although he's also turning around with a swing of his wooden sword, he can't really see where anything is, and he'll stumble over one of his own boots, falling back to sit on his own butt with a wince.]

OI, NOT FUNNY! SERIOUSLY NOT FUNNY! I'm gonna go home, and you're gonna go home, and we're gonna pretend like I never saw you and you never saw me! Got it! Go home and make some hell instant noodles and sit down and think things over for awhile! Dont' be that kinda ghost! Oi, are you listening!?

[Yeah he's still pointing his wooden sword in the general direction of behind him; maybe he hit her, maybe not. It's dark.]
