Mikagura Tanteidan

It was the Taisho era. Mikagura Tokito was the director of a detective agency, which had solved a lot of cases. One day he disappeared, apparently involved in an accident. Tomoe, Shigeno, and Chizuru, who adored him, got anxious thinking about what had happened to him. Hearing that Shigeno's elder brother had seen him at a church in a foreign country, they travelled there hoping to meet him again.
