Before being a killer, Kula is a child. While working for NESTS or for Diana and Foxy, she would not fail to kill anyone she finds unworthy. During her time with NESTS, her feelings were repressed, as she was portrayed as a cold girl executing her mission. She has since been defrosted into being more childish as of late.
Kula is trying hard to establish herself as a humane person, so people don’t look at her as if she is some kind of weapon, she doesn’t use her powers to full extent so she doesn’t kill anyone by accident, because she fears that it would make her go back to her previous ways, so she prefers close combat instead; Kula is usually worried about her foes upon defeating them at times.
Despite being this sweet innocent girl, she tends to have some anger management issues. They are mostly the results of people either talking down to her, underestimating her, or reminding her of her origins and calling her a weapon. She also gets angry whenever she sees flames.
