Plot
The Kingdom of Dowa is subdivided into 13 states, each one granted their own autonomy. These 13 states have many agencies that are controlled by the giant civilian organization known as ACCA. Jean Otus is the second-in-command of the ACCA inspection agency. They keep track of all the activities of ACCA across the kingdom, and keep data on each state's ACCA office flowing toward the central office. One of Jean's jobs is having business trips from the capital to the other districts, and inspect the situation and personnel there.
