Sometimes, when Jean goes out, he wears a black cloak over his uniform and sometimes employs casual clothes when he's travelling to other districts.
Jean is a very emotionally reserved man, typically wearing the same nondescript expression throughout his days regardless of what he is doing. That is not to say that he is emotionless, however, as he values the relationships he has with his friends, his sister and his coworkers in ACCA. He is an affable and easygoing individual, willing to strike up friendships with people he has only just met provided they treat him respectfully. Even when he meets someone who initially treats with disdain, he makes some effort to better their relationship. He is never shown getting angry or sad throughout the series, and the only time he was shown upset was watching the news of his parents' death as a teenager. He enjoys smoking cigarettes and happily indulges in this habit whenever someone offers him one. However, he gets drunk rather easily and tends to drop his stoic demeanor and open up whenever intoxicated. Once he learns of this weakness of his, he makes efforts to avoid drinking.
Jean is the son of Princess Schnee, the 2nd Princess of the Dowaa Kingdom, daughter of King Falke II, and Karl Otus. The King gave Princess Schnee freedom and disguised her death in the sea along with Abend, a respected Guard Corps leader of Dowaa Kingdom tasked to be the Princess's personal guard.
When Schnee and Abend moved to Badon ward, Nino's father, a loyal retainer of Abend followed him and took Nino along to help watch over Schnee. Upon arriving to Badon ward, Schnee parted with Abend, giving him total freedom. However, he continued to watch over Schnee along with Nino's father. Nino's father secretly took photos of Schnee so he can send reports to Abend and King Falke on any kind of developments that happened in Schnee's life. Due to his father's role, Nino came to get accustomed to watching over Princess Schnee's family as well, even after she married Karl Otus and later gave birth to Jean and Lotta. When the train accident happened, Nino was told by Abend to retrieve his father's camera so that it won't be revealed that a member of Dowaa Royal Family is involved in the incident.
