Thanks for the warning.

Preemptively dropped.

I'm reviving this because this series deserves more attention. Will post at least once per episode.

From the get go, you get a great opening that sets the tone. So far the series has been exactly what I expected if I were to set my idea of it solely on the OP: Stylish, Cute, Suave, Complex Plot and/or Complex World to learn about.

Series start with the protagonist leaving for work and her super cute imouto being a typical good sister. Thanks to the morning news, you can see this land is ruled by a King. Jean Otus, the MC, works at the ACCA Headquarters, as a Vice-chairman of the Inspection Department (Kansatsuka), surrounded by cheerful and gluttonous co-workers.

Then it's revealed that they live in Dowa Federation / Kingdom, composed of 13 districts. The shape of this land looks like a bird, although so far I assume it's a complete coincidence and not a man-made shape. ACCA works as management, making sure all 13 districts work properly and collaborate with each other to secure peace and a good standard of living for all the nation.

These are the aforementioned gluttons who engage daily on a 10 o'clock snack without fault. In their defence, I can't blame them. All the food shown so far is drawn to look utterly delicious. Moving on, every district has its own inspection department (if I understood correctly, 14 total: 13 for each district + headquarters), which oversees data output and investigates any arising issues in their jurisdictions. The HQ branch is tasked with auditing the other branches, which falls on the MC's responsibility.

This five visibly distinguished gentlemen are the Five Chief Officers of ACCA, with Grossular seeming to be their leader, based on a comment made in the episode. With ACCA being a 100-year-old agency, I assume Spade might be the second in command due to his apparent age.

I was going to keep making posts in this thread but a hit a wall and couldn't figure out a way to keep exposing this anime without giving away tons of spoilers (albeit minor). Just watch it.
