Grand Hexagon is a city located on the border between France and Spain, designed with six sides to match its name. At the center of this city lies Raika Bank, which stores fifty tons of gold bullion. The facility is equipped with a sensitive alarm system that triggers if even a single gold bar goes missing. Despite this high-security setup, the bank president harbors a secret second identity. This hidden aspect of the leadership adds a layer of intrigue to the otherwise secure financial institution situated in the uniquely shaped border city.
