In the neon-lit shadows of Tokyo’s Shibuya district, a quiet war brews beneath the city's surface. At the heart of this conflict stands Kenji Sato, a loyal and rising figure within the powerful Takeda clan, entrusted by the clan’s calm yet commanding leader, Hiroshi Takeda, with a critical mission: uncover the truth behind the Fujimoto clan’s aggressive expansion before it erupts into an all-out war.
Within the refined walls of the Sakura Lounge, Hiroshi warns Kenji of the Fujimoto clan’s ambitions and charges him with leading a covert team to infiltrate their operations. Assembling a trusted unit—Aiko, a brilliant intelligence specialist, Ryu, a hardened enforcer, and Kaito, a genius hacker—Kenji begins pulling at the threads of a dangerous plot.
What they uncover is more than a turf dispute. The Fujimoto clan is orchestrating a strategic power grab, targeting key Takeda assets and forging secret alliances. With only days before a planned assault on a critical warehouse, Kenji and his team must act swiftly, balancing subterfuge, strength, and precision.
As the city remains blissfully unaware of the silent war stirring beneath its surface, Kenji steps fully into his role—not just as a soldier, but as a protector of the clan’s legacy. In this world ruled by loyalty and blood, the Oath of Silence binds more than just words—it seals the fate of those who dare to rise.
