存在于分为13个自治区的王国中的,巨大统一组织“ACCA”。 由于过去的政变危机而结成的ACCA,已持续守护了国民的和平百年之久。 ACCA本部监察课副课长吉恩·奥塔斯,是个有着“蹭烟的吉恩”这一绰号的、组织里头号难对付的男人。 他一边漫不经心地抽着烟,一边走遍13区进行对不法行为的视察。 盯上这样的吉恩的视线、危险的传闻以及——点心时间。 吉恩的和平日常,慢慢被卷入世界的阴谋!The kingdom of Dowa, which is subdivided into 13 states, is celebrating its monarch's 99th birthday. These 13 states have many agencies that are controlled by the giant organization known as ACCA. Within ACCA, Jean Otus is the second-in-command of the inspection agency. His agency has ten 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 toward the central office. Jean also often has business trips from the capital to the other districts to check on the situation and personnel there.
