A-City (A市 A Shi) is a large city within the world of One-Punch Man. It is the location of the Hero Association headquarters. A-City was completely destroyed by the Dark Matter Thieves, so it is now only inhabited by Hero Association staff and heroes. Metal Knight re-built A-city into an expansive headquarters for the Hero Association with highways leading to all other cities.
