Gender: Male Birthday: May 28th Height: 186cm Appearance: He has a handsome face with black hair and red eyes. Attire: His clothing combines biological and horrific elements like flesh and skulls with the modern, restrained identity of a special operative. The surface of his black leather coat uses a layered embossing technique to evoke the texture of ribs, and the functional details of the suit are designed with the human skeletal structure as a motif. Rust is a spy planted in the West by the 9th Battalion. His elusive nature, moving calmly even through a hail of bullets, exudes a cool and sophisticated yet mysterious and unapproachable aura. Beneath his bandages is a body that is constantly being eroded and replaced. Much like his identities that change without leaving a trace, he harbors countless secrets within. He generally uses polite speech and maintains a gentlemanly demeanor. Due to his status and habits, the subject frequently initiates conversations with people. His eloquence and insight are so exceptional that no complaints were filed; in fact, some staff members proposed a paid conversation service to him, which the Chief immediately shut down for interfering with duties.
