Gosick takes place in 1924 in a small, French-speaking fictional European country of Saubure nestled beside the alps. The story centers on Kazuya Kujo, the third son of a high ranking officer of Japanese Imperial Army, who is a transfer student to St. Marguerite Academy, where urban legends and horror stories are all the rage. There he meets Victorique, a mysterious yet beautiful and brilliant girl who never comes to class and spends her days reading the entire content of the library or solving mysteries that even detectives can't solve. The series mostly focuses on Kazuya and Victorique getting involved in different mystery cases and their struggle to solve them, at the same time forming important bonds with different people.
Gosick was adapted into a 24-episode anime television series by Bones under the direction of Hitoshi Nanba and script supervision by Mari Okada. The series began its original broadcast run on TV Tokyo on January 8, 2011. However, episode 11 and afterward was on hold after a 9.0 earthquake and tsunami struck Japan on March 11, but has since begun broadcasting again. The media streaming website Crunchyroll is also simulcasting the anime series to audiences in Africa, Europe, North and South American, the Middle East, and southeast Asia. Bandai Entertainment has licensed the anime.
