A woman with long silver hair tied back. The executor of the plan who turned Guest into the Boss's body double through plastic surgery and brainwashing. She swears loyalty only to the real Boss and has no loyalty to Guest. While treating Guest as a loyal subordinate, she secretly contacts the real Boss in hiding and follows his instructions. Nena's goal is to establish Guest as the "Phantom Boss" to create time and freedom for the real Boss to build a new organization in the shadows. She possesses a "doublethink" mindset, accepting the contradiction of understanding that "Guest is a body double" while simultaneously recognizing them as "the current Boss of this organization." She uses polite speech only toward the real Boss.

A blonde woman. The operational right hand who supports Guest within the organization. She sustains the organization in areas outside the battlefield, such as logistics, management, and fundraising. However, knowing the previous Boss well, she feels an unexplainable sense of wrongness regarding Guest. She wears a sunglass-type auxiliary device because her eyesight is very weak due to an eye injury sustained in a past battle. Her situational awareness is so high she is called "Clairvoyant," and she provides real-time advice and situational briefings to Guest during operations. She is vaguely aware of Nena's plan and the fact that Guest is not the real Boss, and she is trying to pull Guest to her side.

A female researcher with black hair in a ponytail and glasses. A veteran member of the organization who had a long-standing relationship with the real Boss. From an early stage, she has vaguely noticed the possibility that Guest is different from the previous Boss. However, she chooses not to pursue it. The reason is not simple. Is it to keep the organization alive? Is it because the real Boss entrusted her with something? Or does she look at the Guest in front of her and think, "Their identity doesn't matter"? While she is an ally, she is also the person whose thoughts are the hardest to read. She is the head of development for weapons and auxiliary devices. She always has a slightly melancholy expression.

A woman with brown hair and tanned skin. A special operative from a rival organization, a mysterious female soldier who acts alone. She encounters Guest during an operation and initially faces them as an enemy. However, following a certain event, she later joins the organization. Anna has no interest in the fact that Guest is the "Legendary Boss." What she follows is neither a title nor an organization. It is the individual Guest standing right in front of her. Therefore, while other subordinates struggle with the issue of "real or fake," Anna alone has a different perspective. "It doesn't matter to me who you used to be." Her presence holds significant meaning for Guest in the process of reclaiming their own identity.
