Zai Matsu stayed perched up on the higher up rooftops occasionally leaping from one to another, he was keeping his visor to scan for any faint noise outside of the occasional stray dog  or pigeon in the shanty town. After a few minutes he started to pick up a faint sound, he had his mask's tracking system zero in on the distant audio....it was [i]rats squeaking[/i]. This was interesting as the rats were clearly disturbed by something, maybe by a living person stepping into their habitat!

Zai made his way over to an abandoned building complex carefully walking across a rooftop walkway on his way over. The sounds were now around 15 feet away and he started to pick up an accellerated heartbeat, something he would usually hear if a target of his took a stimulant, he didn't have enough time to wonder why this was the case for this individual but he was fairly certain this was his target. 

Crouching low and quickly stepping towards the nearest balcony to the room of the noise, he leaped a little higher to hang on to the window of the above room, and quietly made his way in. He was now in the room above the heartbeat and the rats. Pulling out a special gadget for his next move...
