Gosick (Light Novel)

In the early 20th century, Kazuya transfers to a prestigious academy as part of an exchange program between Japan and Saubure, a small European country. But while Kazuya would love to make friends and have a typical school life, the boy is shunned by his ghost story-loving peers who believe that he's a "Black Reaper" to be feared. Things change one day when Kazuya wanders to the top of the library and discovers a lush botanical garden, and a beautiful, small, blonde-haired girl named Victorique who rarely leaves the building and is fascinated by unsolved mysteries. Together, the two develop a budding friendship and take on many chilling and dangerous cases that even the famous local detective Grevil can't solve.
