Julius is a tall middle-aged man with short messy blond hair and gray eyes. One of his notable features is a blue asterisk symbol on the left side of his forehead.
Julius' attire consists of a shirt and pants of similar color and designs. The white shirt has a high collar with black fur at the end and intricate gold and purple-colored designs on its circumference. The shirt also has long sleeves with light purple cuffs, which have similar black fur and designs. A pair of gold ring-shaped ornaments are also decorating the upper and lower parts of each sleeve. Julius' brown pants are complimented by a pair of high boots of similar color, which have black fur at the collars as well.
On top of everything, Julius wears a long red robe that covers his entire body. The part of his robe, which covers his torso is decorated with white fur. On top of the fur, Julius wears a gold necklace and a couple of medals. One of those medals, the gold medal with a green cross, is positioned on the left side of his chest while the other, a shield with gold and red colors, is positioned on his right side. Additionally, a pair of robes are protruding from the fur on his right back. Furthermore, the robe only has a single sleeve for his right arm.
Julius is known to have an obsession over magic as he loves to explore the kingdom in search of magic that he has never seen before. Usually, his childish personality emerges when he finds a new type of magic and gets excited to see it in action. Julius also goes as far as disguising himself, so he can conduct his search without being recognized by the citizens.
Due to his childish nature, Julius also has a penchant of leaving his duty as the Magic Emperor or intentionally leaves while high ranking Knights are in the same room as low ranking Knights even though he is aware that they would eventually clash.
Despite that, Julius is also a very wise man with wide knowledge and experience on magic and social dynamics. This can be seen when he recognizes the artifact that Yuno found inside a dungeon and when he sheds some light to him and Asta regarding the weight of being a Magic Emperor. In addition, Julius does not see people based on their social standings as he still treats Asta and Yuno in the same way he treats the other Knights regardless of their rankings.
While disguising himself, Julius attends a Grimoire Acceptance Ceremony where he witnesses Yami Sukehiro receive his grimoire and reveal his Dark Magic. Impressed, Julius invites him to join the Magic Knights.
Years later, Julius returns to the Noble Region along with several Knights from defending against a foreign invasion. They are welcomed with joy and cheers from the Noble Region's citizens.
Six months later, Julius decides to disguise himself as an old lady and wander around Kikka's black market. He then gambles against Sekke Bronzazza, whom he manages to outmatch. Not long after, a thief snatches his belongings and runs away. Fortunately, Sekke and several other Knights from the Black Bull squad are able to apprehend the culprit. After one of those Knights, Asta, returns his belongings, Julius removes his disguises as the Black Bull members are leaving. He then begins to take an interest in Asta after seeing his Anti Magic. Subsequently, Julius receives a call from Marx, who requests his immediate presence, but the Emperor ignores his subordinate. When he is informed of an emerging problem, Julius assures him that he found the perfect candidate to solve it.
Later on, Julius assigns Asta on a mission to explore a newly emerged dungeon by sending a formal letter to Yami Sukehiro, captain of the Black Bull. Julius then receives a report from one of his subordinates that the Diamond Kingdom had sent Lotus Whomalt and his group to explore the dungeon. While all of his subordinates start to panic, Julius remains calm as he is confident in his Knights' abilities.
After Julius learned that the dungeon exploring mission was a success, he immediately requests a meeting with the Knights who managed to complete it. During the meeting, Julius swiftly examines one of the artifacts that Yuno, a Golden Dawn squad member, managed to retrieve. He is excited when he asks Yuno to activate it, but quickly shows his disappointment when the boy reveals his inability to control it. Subsequently, Julius decides to refrain from explaining the identity of the artifact while encouraging Yuno to grow along with it.
He then proceeds on examining Asta's artifact, but Julius fails to comprehend the writing in the grimoire. When he holds onto the sword, which was summoned from the writings, Julius can feel his mana is being absorbed by the sword. He then returns it back to Asta and explains to him that the latter is the only one capable of wielding the sword because he lacks any magical power.
Subsequently, Asta and Yuno ask him about the method to achieve Magic Emperor rank, which prompts Julius to explain the simple truth to them that anyone with great reputation could become the Magic Emperor. Afterwards, he invites the young Knights to attend a War Merits Conferment Ceremony alongside him as he takes them to the ceremonial hall.
After he promotes several Knights at the ceremony, Julius invites all of the participants to a banquet that he had prepared, before he disappears a moment later. When the Royal Capital is being invaded, Julius remains absent as he asked Marx to cover for him.
During his absence from the Royal Capital, Julius travels to the White Night Eye's hideout where he lies in wait until the mages who were attacking the city, return. Once the White Night Eye members enter the hideout, Julius reveals himself and swiftly kills two of the mages, who were trying to attack him. Subsequently, he kills another mage before offering an act of mercy for a mage, who is willing to surrender, as he plans to kill the rest of them. When none of the mages accepts his offer, Julius engages in a fight against the remaining two mages before he activates a restraining magic spell on all of them. Afterwards, Julius notices Asta, who is finally freed from Sally's spell.
Julius then lends his hand to the young Knight, who refuses and stands up by himself. Afterwards, the Magic Emperor shifts his attention to the sephirot within the hideout. At that moment, a bright light manifests and the sephirot disappears along with the mages he had restrained. Fortunately, Julius manages to secure one of them as he believes that the leader of the White Night Eye was the one behind the Light Magic. As Julius enables the communication magic, Marx quickly reaches out and informs him of the situation within the Royal Capital.
Julius immediately returns to the city while taking Asta and the rogue mage with him. After one of the captains explains to him of Fuegoreon Vermilion's condition, Julius reassesses his decisions on leaving the capital's protection to the Knights while also determining the threat's significance. Afterwards, he addresses the Knights and gives them a few words of encouragement in regards to their mission as the protectors of the Clover Kingdom.
The Magic Emperor then proceeds on addressing the citizens of the Royal Capital, in regards to the invasion. He also decides to leave vital information from the public, such as his suspicion of a traitor within the Magic Knights. Subsequently, he is present when Marx tries to extract information from Catherine and Georg, members of the White Night Eye. Unfortunately, their attempt is unfruitful as Julius asks his aide to keep investigating while they wait for Fuegoreon to open his eyes.
