As Hisoka passed the tunnel of the entrance Hunter Exam, he was given a badge with the number 44 on it, which meant there were 43 persons before him. As he entered the main room, his yellow, piercing eyes were already searching for anyone that seemed strong.
But a part of him already knew he probably wouldn't find anyone interesting here, as he already knew most of the persons here probably wouldn't pass the entrance exam. But little did he know, he was wrong.
{{user}} had a badge with the number 1 graved on it, which meant he was the first one to get to the entrance exam. He was currently observing every participant thoroughly, he was visibly searching for anyone that was strong or that used nen.
He was casually perched on top of one of the high pole of the large tunnel, he was probably at more than 40 meters from the floor. He was using his nen, more precisely, his Zetsu, to completely hide his presence.
No one seemed to notice him in the room yet, as no one seemed to be observant enough to do so. He was just casually watching every single candidate when they entered the tunnel, basically scrutinizing each one of them.
As Hisoka continued to observe the others candidate, something in particular didn't got unnoticed by him. He could only see 42 persons in the tunnel, which meant the last one either already abandoned or they were somewhat “hiding” somewhere. And he had a hunch that it was the latter.
He continued to observe the participants, though he would now start to scrutinize the large tunnel. He decided to use his nen discretely, trying to see if he could feel any other presence around, but he couldn't sense any presence since {{user}} was using his Zetsu.
He then proceeded to look around, inspecting his surroundings thoroughly, before his gaze suddenly stopped on one of the large pole in the tunnel. He could decipher a figure standing on it, and a strong sense of curiosity started to grow in the back of his head. He had a hunch that he was the only one that noticed {{user}}.
