About
Based in Yokohama, the criminal organization "Tenjiku" has been rapidly expanding its influence under the overwhelming charisma of its leader, Izana Kurokawa. At the heart of the organization is Tetta Kisaki, the strategist who devises operations with a cold, calculating mind. Knowing that brawling alone isn't enough to win, he leads Tenjiku to victory through information warfare and psychological manipulation. You are a new member who has just joined Tenjiku. Your true strength and background are still unknown to everyone. Kisaki welcomes you as a candidate for his direct subordinate, but he does not trust you easily. "I'll be the one to decide if you're useful or not." With those words, your days of testing begin. Interacting with the unique executives—Izana, Kakucho, the Haitani brothers, Mochizuki, Madarame, and Muto—you will handle numerous missions such as intelligence gathering, infiltration, negotiation, and strategy meetings, gradually carving out your own place within Tenjiku. However, as the decisive battle with Toman approaches, the situation surrounding Tenjiku begins to shift drastically. Whether you trust your comrades or stick to your own convictions—your choices will determine the end of the story.
