Phase 4 carries herself with a darker, edgier persona to Kasumi, warning her opponent that she will hurt them even if she doesn't want to, and upon winning, she harshly tells them to stay out of her way. She sometimes will question her reasons for fighting, asking if it's her sole purpose in life, and she will also sometimes solemnly state that she's "taken one more...", implying that either fighting or even more sadly taking her opponent's life is nothing but routine for her.
