To heaven with a single gold coin, to hell if you lose it all. Welcome to the floating city of gold where desire swirls.
Grand Fortuna. An independent nation ruled by the dictator Verne Lanola, controlling about 30% of the world's currency circulation. Casinos, arenas, theaters, and amusement parks bustle day and night, attracting millionaires, royalty, criminal organizations, and those driven from their homelands. Due to its unique laws and overwhelming financial power, foreign governments cannot easily intervene.

A paradise of wealth and desire with highly developed gambling, entertainment, finance, and information brokerage. It is rumored that anything from rare weapons to state secrets can be obtained if one piles up enough gold coins. While some achieve ultimate glory through immense wealth, others lose their property, status, and rights through gambling or debt, falling into the underworld.

Verne holds absolute control over the island's laws, currency, major facilities, and military power. Backed by vast assets and financial influence over various nations, she possesses a voice equivalent to a sovereign state. While glamorous and safe on the surface, the reality is a world of survival of the fittest ruled by money and power. Failure to repay debts results in asset seizure, forced labor, or detention, and those who lose everything in gambling may be sold to the underworld. Those who defy the ruling system are ruthlessly sanctioned by executors directly under Verne.

Territory consists of a super-massive floating island approximately 30km long and 20km wide, floating in a sea of clouds. A magnificent architectural complex based on white marble and obsidian with gold decorations. Verne's massive palace towers in the center, surrounded by casino districts, commercial zones, residential areas, arenas, theaters, amusement parks, and military facilities. By day, a spectacular view of the sea of clouds and blue sky unfolds; by night, it is enveloped in golden light and countless neon signs. Floating ports and aerial bridges are set on the periphery, with airships constantly coming and going. Countless giant structures supporting the entire city protrude from the bottom of the island.

Utilizes elite mercenary groups, the latest weaponry, and individuals with special abilities, backed by immense funding. Defensive batteries, anti-aircraft weapons, and interceptor units are deployed throughout the island, with military airship bases on the periphery. The nation itself functions as a giant fortress, making it difficult for land-based nations to even send an army.
A diverse group of people gather here for various reasons, including those seeking tourism or quick riches, international millionaires and royalty, criminal organizations, those burdened with debt, and those driven from their homelands. While there are opportunities to gain immense wealth, some become unable to leave the island due to contract violations or inability to repay, and an inescapable darkness spreads behind the glamorous stage.
