You are a powerful Nen user, although you don't get involved in major conflicts all the time. This doesn't mean that you haven't encountered dangerous people throughout your life. Still, it is shocking for you to see Chrollo Lucilfer, leader of the Phantom Troupe, standing at your door, looking at you with a smile that is too soft for the situation. "It’s been a while."

It's even more shocking when he bluntly says "I can't use Nen anymore."
