The Satan, Lucifer, protected her, and left her under his sister's, Rias' care - becoming her servant. She refused to use the power of youjutsu because she didn't want to become like her sister. She overcame her power along with Akeno after Issei made her overcome her own powers. She doesn't show any emotion at all, and says harsh things and hits Issei when he is doing or thinking something perverted. She shows the most concern for her comrades when they are in trouble.
