Yes, that is quite a pity. Surprisingly hardy man if I do say so myself, typically such tenacity should be commended but this fellow is simply becoming an annoyance....

[Mukuro squats down by the tracks to take a look for himself. Perhaps this one was an illusionist as well? He would have to be QUITE the skilled one to fool Mukuro though... he leans down to where the tracks end, observing curiously. No illusion that he could see]

Usually I would say it's all a matter of perception, but that doesn't seem to be the case here... at least not as far as I can see.

[He stands back up with his trademark smile.]

Ah, my apologies, how rude of me. I am Rokudo Mukuro, it's a pleasure.
