"It is not usually a prominent scent when we see one other again, but I'm never away from you long enough to lose it completely," he says, confirming her speculation about his stronger sense of smell playing a factor given his only means of her scent is Mizu herself.

Although in Vergil's case, Mizu is right. It's not the scents of work that tend to linger in place of her scent when it begins to fade, but the the scents of his family. Because it's rare these days that Vergil is able to read without someone coming to rest upon him, and that includes his brother and son when they want his attention. And while it's more of a friendly competition than it used to be between brothers and a matter of training for his son, he still occasionally spars with each of them around various places in Folkmore. Vergil also stays in the garage for a little while to listen to Nero excitedly explain his latest project to him, and concedes to Dante's whims for dinner on occasion.

But he still has traces of Mizu. Faint and fading, and likely imperceptible to her human senses, but still there nonetheless.
