Description
Joseph Kō Hiraga is one of the two protagonists of Vatican Miracle Examiner. He is a young Japanese Catholic priest in his mid-twenties who serves as a miracle examiner for the Vatican, tasked with traveling the world to verify or debunk reported supernatural events. His physical appearance is distinctive, characterized by jet black hair, pale skin, and almond-shaped eyes, with dark bags under his eyes that betray a chronic lack of sleep. He has a short and petite frame and pays very little attention to his own appearance, almost always wearing his clerical cassock and white gloves, though he has no issue stepping outside in his pajamas if necessary.
Hiraga possesses a deeply kind and warmhearted personality, combined with a strong and unwavering Catholic faith. He tends to see the good in everyone he meets, often to a dangerous degree, because he is trusting and believes people are moved by kindness and good intentions, reflecting his own nature. He is straightforward and can be blunt, sometimes struggling to understand jokes or sarcasm. Despite his devout faith, he is remarkably open-minded and accepting. His most defining personality trait is his intense intellectual focus; he can become so wrapped up in scientific experiments or projects that he neglects his own basic needs, frequently forgetting to eat or sleep, which forces his partner to remind him to take care of himself.
Born in the United States to a Japanese-American primatologist mother named Ada and a Japanese musician father named Jin, Hiraga moved to Germany with his family during his childhood, where he grew up with his younger brother, Ryota. He proved to be a brilliant student, advancing three grades, completing high school at fifteen, and earning a PhD from the University of Berlin at the age of seventeen. Despite attracting attention from many scientific organizations, he chose to join the Vatican instead. A significant personal tragedy shaped his life: his mother was diagnosed with cancer while he was at university and died before he could say goodbye. Shortly after, his beloved younger brother Ryota was diagnosed with osteosarcoma, a form of bone cancer. Hiraga works tirelessly for the Vatican largely to earn enough money for Ryota's expensive medical treatments.
In his role as a miracle examiner, Hiraga partners with his close friend and colleague Roberto Nicholas, a relationship that forms the core of the story. The two complement each other perfectly: while Hiraga approaches investigations with scientific methodology, Roberto provides expertise in history, theology, and cryptanalysis. Their partnership extends beyond work, as Roberto takes care of household chores and cooking for Hiraga, who is practically incapable of managing daily life on his own. Within the Vatican hierarchy, they answer to Archbishop Saul, the chief of the Seat of the Saints, who holds great respect for their dedication. Hiraga also forms a unique bond with Lauren Di Luca, a genius hacker imprisoned by the Vatican whom he plays an original and complex board game called the Game of Angels and Demons against, similar to Go, which Hiraga himself invented.
Hiraga is an intellectual prodigy whose areas of expertise include biology and physics, and he always carries his scientific equipment with him. His investigative methods can be highly unconventional, sometimes even tasting unknown substances during his analysis, and he often assists police with autopsies while preferring to work alone. He is fluent in multiple languages, including English, German, Italian, Latin, and Japanese, though he lacks confidence in his native Japanese skills. His intellectual pursuits include collecting bugs and creating a complex board game that allows him to see up to 300 moves ahead under optimal conditions. Despite his scientific rationality, he remains a devout Catholic seeking miracles that cannot be explained by science, though his approach is pragmatic rather than superstitious; on one occasion, he prepared sulfuric acid instead of holy water, explaining that the target they faced was a psychopath rather than a demon, so self-defense required a more practical solution.
Throughout the series, Hiraga faces significant tests of his character and faith. When confronted by the secret society Galdoune, which offers advanced medical solutions for his dying brother in exchange for his allegiance, he refuses despite his desperate concern for Ryota, upholding his professional integrity and moral boundaries. His devotion to his younger brother manifests in frequent nightmares and visions reflecting his psychological strain. As Ryota's condition worsens, particularly in the Italian story arc, Hiraga's determination to validate divine intervention by scientifically eliminating all alternative explanations grows even stronger. While some reviews note that the anime adaptation provides limited development of his backstory compared to the original light novels, Hiraga's core motivation remains consistently clear throughout: reconciling empirical evidence with spiritual belief, seeking scientific validation of miracles to affirm divine existence while desperately trying to save his brother's life.
