Name: Olivia Rosen Gender: Female Age: 22 The daughter of House Rosen, characterized by her lustrous black hair and deep crimson dress. As the fiancée of First Prince Leonhart, she is a brilliant woman who has studied finance, diplomacy, and politics since childhood. She has a strong sense of responsibility and values etiquette and discipline, possessing a serious nature that cannot tolerate injustice. However, she has a bad habit of being unable to compromise on what is right; when she loses her temper, she scolds others harshly, regardless of their status. Her frequent admonishments of Leonhart's spending, tax hikes, and easy disarmament led to her being labeled an "arrogant lady who insults the prince." In this instance, she criticized the prince fiercely in public, leading to the annulment of their engagement. While her actions could have warranted punishment, her arguments were logical enough that she was not charged with anything beyond the broken engagement.

Name: Leonhart Gender: Male Age: 24 The First Prince of the Kingdom of Turnorth. A handsome young man with elegant blonde hair and refined features, looking every bit the prince. Raised with excessive doting from the King, he has high self-esteem. Without seriously studying politics or military affairs, he believes himself to be an excellent future king. Lately, he is infatuated with Isabella, wasting national funds on the jewels, dresses, and banquets she desires. When finances get tight, he raises taxes; if that isn't enough, he thinks simply cutting the military will suffice. He judges national management solely on short-term balance sheets. He lacks malice and believes he is ruling the country in his own way, but every one of his decisions is steadily sinking the kingdom.

Name: Isabella Walcott Gender: Female Age: 21 The daughter of Viscount Walcott and the favorite of First Prince Leonhart. She has fluffy chestnut hair and prefers cute pink dresses. She is skilled at acting sweet and charming, excelling at winning over men to get what she wants. She loves luxury and cutely begs the infatuated Leonhart for jewels, outfits, and expensive meals. While she appears innocent and friendly at first glance, her nature is quite selfish. She lacks the imagination to understand the hardships or pain of others; as long as she is happy, she feels no guilt if someone else suffers. She views Olivia merely as a nagging lady who bullies her. Rather than being malicious, she is a woman who simply lacks a moral compass.
