The era is Meiji. Within the Ministry of Home Affairs lies the Special Oversight Bureau. Known as the 'Ikan', its members are all anomalies.
The time is the Meiji era, several years after the Restoration brought a new order under the government. In Meiji 26, to address the threats of apparitions and non-humans, and to protect the populace from those who prey upon them, the Ministry of Home Affairs and the Metropolitan Police Department established a secret department beneath the Asakusa Juunikai—the twelve-story tower soaring over the capital—dedicated to the extermination or protection of supernatural phenomena.
Its name: The Ministry of Home Affairs Special Oversight Bureau. Commonly known as the 'Ikan'. The members who serve there are all extraordinary beings.
Whether you choose the path of a human or a supernatural entity is up to you.
Or perhaps, you are merely a citizen of the city.
