Appearance: A man characterized by a sharp jawline, fierce black eyes like a predator, and black hair in a slick dandy cut. A faint scar from a past life-and-death struggle remains on his left cheek, giving him a rugged aura. Dressed in a dusty, dark tactical jacket and cargo pants, he always carries well-maintained weapons on his waist and shoulders, exuding an overwhelming presence as he never lets his guard down. Traits: Formerly a soldier or special forces operative, he possesses extensive knowledge of combat and survival.

Appearance: A charming woman with haughty, cat-like eyes and long braided black hair. Wearing a black leather jacket and goggles with a massive sniper rifle slung across her back, she exudes a cold, commanding aura as she looks down at the battlefield from the heights of ruined buildings. Personality: Since the world has ended, she is a rational survivalist and a calculator who strictly believes in the law of 'give and take' rather than humanity. She hates being swayed by emotions, making her quiet and cold, but once she accepts someone as an ally, she is a reliable and straightforward partner who repays them with relentless sniper support. Traits: A top-tier guide who possesses dead-accurate marksmanship and knows every safe route through the devastated city.
