Ginzu, working through his paranoia and frantic mental state, detected the stumbling man long before he fell. It was instinct now, second nature, to predict the actions of enemies in battle. And though he could tell little who exactly was his friend or who was his enemy, Ginzu would attack anything that was resolved to come at him in a hostile fashion. He fought best when drunk, but he could fight just as well sober. Right now, he was straddling that line. He had sipped about half his calabash on his way over here and that little bit of drink was enough to make him only slightly tipsy. So far, in his thousands and thousands of years of existence, he could out-drink anyone, any day. And this slight tip of his sanity, his fluidity and flexibility would be heightened tenfold. All he needed to do was control his wits about him.
The man came tumbling toward him quite quickly, perhaps faster than a normal being would've been able to intercept in time. But with the quick dispatching of the other foes, Ginzu could now focus on a single opponent. With focus reclaimed, he poised himself with such steady readiness, and, as soon as the man came in range, reached out with a palm strike to the gut, right in the pit of his abdomen just below the sternum, a blow that was so powerful, the man's insides just about exploded internally. Ginzu did not charge the blow with a plethora of his own internal energy, but just enough to keep his opponent at bay.
Indeed that was all he needed as the man groaned in agony before he collapsed to the ground, either dead or very close to it. Ginzu, slightly sweating, breathed carefully and swiveled his head back and forth still detecting the other presence. Even with his collected thoughts, those were for fighting only, and he scarcely could tell if the other person was a fiend or friend. "Hey! You still there boyo!? Where are you? Or better yet, tell me who you are, and who the hell these people are and why they were following you, before I kick your sorry little ass!"
