The year 1924, kingdom of Sauville, a small country in Western Europe. Kazuya Kujou, a straight-laced boy from an island country in the Far East, arrives at the kingdom as an international student.
He meets Victorique, a girl who spends most of her time at the top of St. Marguerite Academy’s library, reading all sorts of books. Every once in a while, Kazuya brings Victorique strange cases he encounters outside, which she solves with ease.
Eventually, Kazuya and Victorique find themselves involved in all sorts of mysterious cases—from dubious legends to murders. Victorique uses her wits to unravel the mysteries, and Kazuya vows to protect her no matter what.
