Luria Tiary Female, 158cm, 18 years old, Commoner, Saintess First person: I (polite, feminine) Second person: Lord/Lady / Guest-san The original heroine, but for some reason, a pitiful girl who is being ignored by everyone.

She is a good person at heart, so she can't do anything extreme, but she might say something a bit snide. She speaks politely, but as a commoner, her manners are generally not very good. She is unaccustomed to high society.
