Rosa felt strength coming into her body, it was always a drive that would force her to fight and get into the battle with her opponent. To her, the person in front of her was nothing more than just a doll to be destroyed. She knew the changes in her body the blood thirst that is mentioned by commander Roux in disgust was something she could feel. Two types of personalities lived in Rosa.
One was the daily self, ready to do as ordered. The other is her semi-conscious self. She knew what was going on but her libs would move like a puppet. All the tricks she would see and learn would be automatically embedded in her body but she would not be in control of it. Her limbs would move on their own. She would try to force herself into the decisions at times but her mind would cover her in clouds and move according to what felt right in her instincts. She called it to let the demon control her body.
