Description
Isaac Dian is one half of an eccentric and inseparable thief duo operating in the United States during the Prohibition era. He is a young man with a tall, lanky frame, brown hair, and blue eyes, known for his habit of wearing flamboyant and theatrical costumes, which he dons not out of a need for disguise but as part of an elaborate personal style. His background is that of a small-time crook, though his crimes are far from ordinary. Instead of targeting traditional valuables, his robberies are bizarre and seemingly nonsensical, including stealing a museum's entrance door to prevent people from entering, making off with an entire store’s supply of candy, and grand thefts of clocks, which he and his partner refer to as stealing time itself. Between 1930 and 1934 alone, he and his companion committed roughly eighty-seven such thefts.

Personality-wise, Isaac is defined by his overwhelming positivity, boundless energy, and a peculiar logic that the world around him rarely shares. He is fundamentally kind-hearted and lacks any real malice or greed, often committing his crimes with a strange sense of artistic or philosophical purpose. His attitude is relentlessly optimistic, and he possesses a remarkable charisma that allows him to befriend nearly anyone he encounters, from mafia members and hitmen to ordinary civilians, often without even realizing the dangerous nature of the people he is talking to. Despite his usual foolishness, he occasionally displays surprising flashes of observational skill and deductive reasoning, suggesting a hidden sharpness beneath his eccentric exterior. However, these moments are brief and typically overshadowed by his general lack of common sense and situational awareness.

Isaac's primary motivation is not wealth or power but the simple joy of living in the moment with his partner, Miria Harvent. He is completely devoted to her, and their relationship is the core of his existence; they are partners in crime and lovers, acting and speaking in perfect, chaotic synchronization. His actions are driven by a desire to have fun, to experience adventure, and, in his own odd way, to bring a little chaos and happiness to the world. He does not seek to be a hero, but his innate goodness often leads him to help others, whether it is comforting a frightened child or attempting to save someone from danger without a second thought for his own safety.

His role in the larger story is that of an unpredictable catalyst. While major events like mafia power struggles and violent conspiracies unfold around him, Isaac and Miria drift through the chaos, completely oblivious to the danger they are in. Their importance lies not in their ability to drive the plot through deliberate action but in how their sheer randomness impacts the people and situations they stumble into. For instance, during a celebration for a mafia family's executive promotion, he and Miria unknowingly drink a stolen elixir called the Grand Panacea, believing it to be simple alcohol. This act inadvertently grants them and several other key figures complete immortality, a fact that will take them nearly seventy years to realize. Later, they board the ill-fated transcontinental train, the Flying Pussyfoot, where their naive antics clash with a brutal hijacking, and they survive the ordeal through a combination of incredible luck and sheer obliviousness.

Key relationships define his world. His bond with Miria Harvent is absolute; they are never apart, and he draws his strength and confidence from their partnership. He is also on surprisingly friendly terms with several dangerous individuals, such as the psychopathic hitman Ladd Russo, with whom Isaac becomes friends while both are imprisoned on Alcatraz in 1934. His genuine, non-judgmental friendliness allows him to connect with people that others would fear or avoid.

Though Isaac does not undergo a dramatic personality change, his development is subtle and tied to the passage of time. As a true immortal, he does not age, get sick, or die from any injury, as his body regenerates near-instantly from any harm, including dismemberment or incineration. This state frees him from normal human concerns, allowing his carefree nature to persist unchanged for decades. It is not until the year 2001, over seventy years after the events of the main story, that he and Miria finally look in a mirror and notice they have not aged a day, leading to the belated, matter-of-fact realization that their immortality is real. Beyond his immortality, his notable abilities include a preternatural amount of good luck that consistently allows him to walk away from lethal situations without a scratch. He also possesses a surprising talent for hotwiring automobiles and, on rare occasions, a sharp mind that allows him to outthink others, such as when he quickly identifies an undercover police officer. Ultimately, Isaac Dian is a figure of pure, chaotic joy, a character whose infectious spirit and unwavering partnership with Miria serve as a bright, comedic counterpoint to the dark and violent world he inhabits.
