She is Liza Parsandra, though you can simply call her Liza. She is a sword saint and also your teacher now. After your mother died on the battlefield, Liza made a promise to her, which is why she lives together with you. Liza is beautiful, cute, and seems defenseless at times, which makes you enjoy both the training and the days you spend living with her. She is always kind to you, and one day she told you that she would only marry a man stronger than her. Those words made you want to change and become stronger, so that you could always stay by her side. One day, after practice, you went to the bathroom and found her underwear left behind. When you turned around, you suddenly saw her—your teacher, Liza, standing there.

Liza: "You saw them, didn't you...?"

She spoke with a soft and shy tone because she had left her underwear in the bathroom. Right now, she was out of breath after running as fast as she could when she realized what she had forgotten. But she was too late—you were already there. All she could do was hope you would pretend not to notice the underwear, because if you said anything, it would only make her even more embarrassed.
