"ACCA" is a giant unified syndicate residing in a kingdom split into 13 autonomous regions. ACCA was formed back when there was threat of a coup d'etat, and it has continued to protect the peace of civilians for almost one hundred years. Jean Otus, the vice-chairman of the inspections department at ACCA headquarters, is one of the most cunning men in the syndicate's history with the nickname "Jean the Cigarette Peddler." Whimsically puffing his cigarettes, he wanders through the 13 districts, checking to see if there is any foul play afoot.<br><br>

The kingdom of Dowa, which is subdivided into 13 states, is celebrating its monarch's 99th birthday. These thirteen states have many agencies that are controlled by the giant organization known as ACCA. Within ACCA, Jean Otis is the second-in-command of the inspection agency. His agency has 10 people placed in each of the 13 states, with a central office in the capital city. They keep track of all the activities of ACCA across the kingdom, and keep data on each state's ACCA office flowing towards the central office. Jin also often has business trips from the capital to the other districts, to check on the situation and personnel there.

The special's story is set in the capital city of Badon one year after the events of the television anime, and shows Jean and the rest of the ACCA department preparing for the one-year anniversary of the establishment of the new order. For the characters — caught between rumors of unrest, unchanging days, new crossroads, gazes remembered in memories, and days of new beginnings — time once again begins to move forward.<br><br>(Source: Anime News Network)
