| I should have been the one to fill your dark soul with liiiiiiiiiiight! |
Hollow Kat is a character in Vergil's Downfall.
After revealing that Vergil has three holes in his heart, Hollow Vergil sends him to a hellish facsimile of Limbo City, where he finds "Kat" being chased by an Imprisoner. He manages to dispatch the demon just after it corners her, but "Kat" reveals herself to be a demon and mocks Vergil, telling him she chose Dante over him. In a rage, he kills her and is told by Hollow Vergil that he has filled a hole in his heart.
