The Apprentice is a possible love interest for Julian. During the height of the Red Plague 3 years prior, the apprentice worked under Julian at his clinic. The details of their relationship during this time are unknown. Eventually the apprentice would contract the plague, leading to their quarantine at the Lazaret and subsequent death. Julian was oblivious to his apprentice's sickness until after their death, too absorbed in finding a cure for the plague. At the start of the story, Julian breaks into the apprentice's shop seeking Asra. The two do not recognize each other, as both of their memories have been wiped. When the apprentice later arrives at the palace, they learn that Julian is thought responsible for the Count's murder and it is their job to find him. Although they meet at several points during the prologue, the Apprentice chooses to investigate further before condemning him.

During his route, Julian quickly begins a physical relationship with the Apprentice, but later 'breaks up' with them, explaining that he doesn't want to drag them into his messes. In truth, Julian is afraid of hurting them. The Apprentice later confronts him alongside Portia as he is drowning his sorrows in Salty Bitters. The two drag Julian back to reality, and the apprentice makes it clear that they are not giving up on him and are intent on proving his innocence.

Throughout his route, Julian regains missing memories with the help of the apprentice. When he regains the memory of speaking to the hanged man, he is determined to replicate it by facing his own death. The apprentice is against this idea, fearing for Julian's life, and offers an alternate plan that involves them entering the Hanged Man's realm together. When this plan ultimately fails, the apprentice has no choice but to watch Julian's execution and hope his mark is enough to bring him back to life. Their connection ultimately allows the apprentice to join Julian in the Hanged Man's realm again, although the apprentice

Julian has a flair for the dramatic. He is charismatic, theatrical, and frequently a magnet for attention, both good and bad. Several characters view him as overly dramatic, seeing his self-sacrificing behavior as going beyond altruism into masochism. Portia sums up this vexing trait of his by saying that Julian is "always shouldering someone else's burdens while lamenting how heavy the load is." Julian struggles with accepting the help of others, instead frequently diving headfirst into dangerous situations under the guise of protecting someone else. Julian has always been protective of those he cares about, most notably with his younger sister Portia. However, his belief that he is unworthy of love and support has transformed his protective nature into recklessness.

Despite being a condemned criminal, he is reportedly loved by the majority of the Vesuvian public, which shows how he can be magnetic and charming. According to Asra, he is able to excite others with ease and make them feel special, although Asra implies this is only because Julian is selfish and manipulative. The Apprentice is frequently warned against putting their guard down around him, even, notably, by Julian himself. However, it appears that Julian does not have any ulterior motives, and just genuinely desires love and affection. During his route, he often reveals this vulnerability to the Apprentice. However, his self-loathing often causes him to shut out those who try to help him.

Although Julian often attempts to maintain a guise of bravado, this air of confidence is shattered with comical ease whenever he is shown genuine affection. He is easily flustered in romantic instances with the Apprentice.

Julian is a tall, gangly man with curly auburn hair. His grey eyes are usually half-lidded, with dark, purplish shadows around them. His right eye is covered by a black eyepatch. Underneath, the sclera of his right eye is blood red. Julian has pale skin with a flush of color across his cheeks and nose. He has a prominent aquiline nose, a sharp jaw, and defined cheekbones.

Julian typically wears a gray-colored outfit reminiscent of a Howie lab coat, with a large flap across the chest held by silver snap buttons. The long sleeves of his top end in black leather, elbow-length gloves. A dark navy waistband with two tassels separates the top from tight pants that end in knee-high boots. Underneath, he wears a white dress-shirt tucked into his pants. Julian also frequently has a large black trench coat thrown over his shoulders. The inside of the coat is bright red.
