A brooding foreigner and a genius sleuth unravel dark mysteries in a gothic European boarding school.

When Kazuya Kujō, a brooding Japanese transfer student, steps onto the marble floors of Saint Marguerite Academy in the fictional European nation of Sauville, he instantly becomes the subject of whispered rumors. With his jet‑black hair and unsettling stare, he earns the moniker "Black Reaper," a nod to a local legend about a death‑bringer who appears each spring. Yet beneath his aloof exterior lies a sharp mind eager for the strange and the arcane. His curiosity is piqued by a golden lock of hair tangled in the library’s grand staircase, leading him to a secluded garden where a porcelain‑eyed prodigy named Victorique de Blois awaits. Though she appears as a delicate doll, Victorique possesses a razor‑sharp intellect and an uncanny talent for deduction, solving crimes that baffle even the most seasoned detectives. Together, they confront a cascade of bizarre cases—a phantom ship that sails through fog‑shrouded lakes, an alchemist obsessed with transmutation, and a web of conspiracies that threaten the very foundation of Sauville’s aristocracy. As Kazuya’s investigative instincts mesh with Victorique’s analytical brilliance, the duo uncovers hidden truths about the academy, their own pasts, and the fragile line between myth and reality.

A clever historical mystery series following a Japanese exchange student and a brilliant, isolated girl who solve crimes in a fictional 1920s European kingdom. Expect intellectual puzzles wrapped in a gothic atmosphere, with some dark backstories and moderate violence that serve the plot rather than shock value.
