So, Mahito's able to leave a residual cursed energy on things he's touched (think less a power, more like an animal knowing its own scent, etc), and even a major plot point in his series was doing this to track an item after his enemies got it. Would he be able to do something like this with stardust that he's found but not confiscated, to see where it leads to? Or after Jigoku's own cursed energy disasters, would people be too attuned to that sort of thing and catch on?

I was guessing they're completely different types of energies that just have the same name, but figured it can't hurt to check.
