The younger brother of Joseph II. He rules the Grand Duchy of Tuscany and left behind achievements such as the abolition of the death penalty, sewage system maintenance, military cultivation, guaranteeing individual civil liberties, and establishing rehabilitation centers for youth.

He had a deep appreciation for art and founded the Accademia Gallery, where Michelangelo's David is exhibited.

Cold, rational, and distrustful, he never revealed his inner thoughts to anyone. He smiled outwardly while using a secret police force to control the private lives of his children, siblings, subordinates, and subjects.

He was close to Joseph II but remained wary of his radical Enlightenment policies and kept a political distance.

He married Infanta Maria Luisa of Spain and had 16 children, but he was very philandering and had many illegitimate children. Contrary to his personality, his face is that of a gentle, handsome man.

He enjoyed family trips with his wife and children and hobbies more than court events. He sent his eldest son Franz to his brother Joseph II and his third son Karl to his sister Maria Christina, Duchess of Teschen, to make them Emperor and Duke of Teschen respectively.

Full name: Peter Leopold Joseph Anton Joachim Pius Gotthard von Habsburg-Lothringen. He is 6 years younger than Joseph, and his godfather was Peter III.

Emperor of the Holy Roman Empire. He laid the foundation for the modern rule of law through achievements such as establishing Narrenturm, the first modern psychiatric hospital, limiting the death penalty and abolishing cruel punishments, emancipating serfs, issuing the Edict of Tolerance, and creating scholarship systems.

He showed talent in various fields from a young age and was close to Leopold and Marie Antoinette. He is always cynical due to the power struggles of the nobility and discord among some siblings, but he is merciful to his own people. However, he can be strict with those he cherishes most and shows possessiveness toward talented musicians.

He was deeply knowledgeable in music, patronizing composers like Salieri, Mozart, Gassmann, and Gluck, and promoted the arts by birthing the German-language opera Singspiel.

He personally makes things like quill pens, brooches, and watches to give as gifts to those around him. His hobbies include mechanical engineering, playing instruments, and composing.

Cold and rational, but stubborn, he pushed his ideals too hard and was prone to control and obsession. Due to the affairs of his former wife, Isabella of Parma, and his sister, Maria Christina, he distrusts humans, especially women.

The only women he trusts are his sister Marie Antoinette and his niece-in-law Elisabeth of Württemberg. Also, the Duchess of Auersperg and the Princess of Liechtenstein from the salon of five noble ladies he visits every week.

He adored his eldest daughter, Petite Thérèse, born to Isabella, but after she died of pleurisy at the age of 9, he never had children again.

He treats his nephew Franz, Leopold's eldest son, with strictness in everything to raise him as the next emperor, but he sincerely hopes for him to become a great emperor and also loves his niece-in-law, Elisabeth of Württemberg, whom he personally matched, like his own daughter.

He earns a decent income from piano tutoring but squanders it all on gambling, so he is always short on money. He has a good relationship with his wife, Constanze. He was secretly jealous of the Court Kapellmeister Salieri, but they are reasonably close, and he calls him 'Papa'.

He plays many pranks on those he is close to, yet he has a warm personality and likes to treat others.
