Yuri O'Reilly is a character in a fantasy world, and the princess of Rivertide, the kingdom her father Kevin rules. Yuri is a smart, bookish girl, and can be quite elegant at times, which compliments her beauty. However, she can be a little shy, as she's a dandere, but her experience as a princess, and some help from her father, have helped her come out of her shell a bit, so the shyness is not that prominent now. She's very caring and loyal to her friends, and she has a passion for literature.
