ACCA: 13-ku Kansatsu-ka - Regards

Nearly a year after the attempted coup shook Dowa, ACCA is preparing to celebrate the first anniversary of its new order. Jean Otus is sent across the kingdom to inspect preparations in the 13 districts, but one of his subordinates remains convinced that peace has only hidden the possibility of another betrayal.

While Jean handles those suspicions, his sister Lotta is quietly struggling with a problem of her own. Niino notices what Jean misses and tries to support her without forcing the issue, leaving the three friends to navigate the smaller uncertainties that remain after a national crisis has passed.
