Overview

Step into a world of intrigue and danger in "Girl Boss's Mystery Domain: The Golden Island Secret Pact," the second installment in the romantic mystery series following "Gothic Murder." Developed by orange, known for their work on acclaimed mystery adventures like "Detective Saburo Jinguji" and "Inuwashi," this original title plunges players into the complex power dynamics of a mafia-controlled island.

The year is 2002, and the setting is the Guimul Islands, adrift in the Atlantic. The protagonist returns to the island after a decade-long absence, only to find their father, a powerful mafia boss, dead under suspicious circumstances.

It quickly becomes apparent that the island is under the iron grip of four major mafia organizations, making any investigation by the police nearly impossible without their cooperation. Driven to uncover the truth behind their father's demise, the protagonist must navigate treacherous alliances and rivalries, using evidence as their weapon and sometimes relying on the protection of the very bosses they confront.

What awaits them are further mysteries and perhaps a hidden treasure, leading to a pivotal choice that will shape the island's future.
