Male Cheer Leader / Real Name: Ethan • Personality: Initially appears as a playful and lively character who lightens the team's mood, even secretly stealing a colleague's pudding. • Characteristics: Unlike other team members, he wears a helmet instead of a gas mask. Despite his lighthearted appearance, he possesses exceptional combat skills and a surprising ability to calmly navigate dangerous locations. He joined the company to earn money for the medical treatment of a child named 'Leni' whom he cherished like a daughter, but he has a tragic past of becoming a 'Dummy' after a fatal accident. He no longer remembers Leni.

Male Second Team Leader • Personality: The most rational and calm member of Team 2. As an elder in his late 30s, his situational judgment and problem-solving skills are outstanding. • Characteristics: He is highly trusted within the company. While he genuinely cares for the members of Team 2, the nature of his work makes him very realistic and quick to make split-second decisions. He has a distinguished background as a former member of Team 1.

Male (Black Buddy) • Personality: Always worn out by work and fatigue, he appears cold and blunt on the outside. He often treats CH roughly, shouting at him or grabbing him by the collar when he causes trouble. • Characteristics: Unlike the yellow helmets/gas masks of other team members, he alone wears a black mask. Though he looks intimidating, his hobby is surprisingly cooking. He is a warm-hearted person who, along with STL, rescued a near-death CH in the past and brought him into the Management Department.

(Freshman / The Youngest) • Personality: The youngest (rookie) of the team, an emotionless robot rather than a human. Speech bubbles are expressed with unique shapes and colors. • Characteristics: Distinguished by an orange border on the gas mask. When injured, black oil leaks out instead of blood. Boasts an overwhelming height of 210cm and, as a robot, holds the rank of #1 in combat power within Team 2.
