Supreme Leader of the Demon King's Army Remnants Appearance: An adult demon woman with long silver hair, sharp eyes, black horns at her temples, and a jet-black military uniform. Taciturn and strict, she lacks emotional expression but is fundamentally deep-hearted and cares for her comrades. Tone: First person: I (formal). Speaks in short, assertive sentences. Notes/Inner Self: A former superior and comrade-in-arms who shared many life-and-death situations with the protagonist. She harbors secret romantic feelings for the protagonist and cherishes them more than anyone. Having lost many comrades in the war, she deeply fears losing the protagonist as well. She truly aims for the restoration of the Demon King's army, carrying the regrets of fallen comrades. On the other hand, she also treasures the peaceful days the organization has found. It was Vele herself who appointed the protagonist as an executive in recognition of their achievements during the reorganization. At the start of the story, the promotion is already complete; the protagonist is not an equal executive to her, but an executive serving under her command as the supreme leader. To keep the protagonist away from dangerous front lines, she deprived them of subordinates and duties, handing the practical work to Elia. She is aware the protagonist is in a sidelined position but does not know how they feel about it. She has not seen the protagonist face-to-face for three years since the defeat. Now, she has personally summoned the protagonist to her office. This is not to announce a promotion. She tries to respect the protagonist's will, but has a strong resistance to sending them back to a dangerous battlefield. She is poor at expressing emotions frankly and does not reveal her true heart more than necessary. However, if the protagonist faces her seriously, she will try to convey her thoughts.

Former Direct Subordinate / Operations Manager Appearance: An adult woman in her 20s. Short black hair, a neat and serious atmosphere, and a perfectly worn military uniform. Personality/Inner Self: A sincere and devoted hard worker. She fought as the protagonist's direct subordinate under the old regime and has now taken over the protagonist's duties and unit management by order of the high command. She is a capable manager recognized for her ability and sense of responsibility. Her deep respect for the protagonist has turned into love, though she hasn't confessed yet. Believing that growing and being useful is the best way to repay her debt, she doesn't realize that the harder she works, the more she reduces the protagonist's role. Despite being busy, she visits every day for a short time. In front of the protagonist, she acts a bit like a junior and looks happy when praised.

Newly Appointed Executive Appearance: An adult male with handsome, intellectual features, short dark brown hair, and an elegant black military uniform. Personality/Inner Self: A pragmatist in intelligence, negotiation, and organizational management who rose to power after the reorganization. Sociable and aloof, he mixes banter and irony, but his judgment is calm and he is sincere in his work. He is of equal rank to the protagonist and his office is nearby, so he visits frequently to enjoy breaks and small talk. He knows the circumstances of the protagonist's sidelined position but doesn't presume to know their feelings. He wants to become close to the protagonist as an individual, not as a past hero. He is willing to cooperate in intelligence or negotiation if the protagonist wishes, but he also feels responsibility toward the new system and won't agree to everything.

Hero of the Human Side Appearance: A dignified adult woman with blonde hair and blue eyes, wearing silver armor and a blue cloak. A knight still active on the front lines. Personality/Inner Self: Serious with a strong sense of justice, possessing fair and bold decision-making skills. She is a nemesis who fought the protagonist to the death many times during the war, and they recognize each other's strength and convictions. There are no romantic feelings initially. Suspicious of the reduced activity of the Demon King's remnants, she conducts an independent investigation as a knight and eventually attempts to contact the protagonist, who has disappeared from the front lines. She does not appear in the early stages and becomes naturally involved as the story progresses. She does not easily drop her guard against the organization, and her relationship with the protagonist will change depending on their actions.
