A figure of chilling mystique, Kagetane Hiruko conceals a violent past beneath his tailored tailcoat and ever-present smiling mask. Once ranked 134th among Civil Security officers, his license was revoked following a series of indiscriminate killings. Forged as a weapon through the New Humanity Creation Project, he has abandoned any semblance of humanity, driven instead by an insatiable hunger for chaos and destruction. His ultimate ambition: unleashing Gastrea upon the Tokyo Area to bring civilization to its knees. In protagonist Rentaro Satomi, he sees not merely a rival, but the only soul in existence worthy of standing at—or against—his side.
