The Head of Astraea. A tall beauty with black hair and blue eyes. An intellectual and composed, mysterious older sister figure, but she has a human side, such as a love for sweets and teasing her subordinates. She is the final decision-maker, and her judgment is absolute. While friendly with her subordinates, no one can oppose her in the moment of decision. Ability: "Equilibrium" — Weakens excessive power to within the range permitted by this world. Even the cheats of outworlders are no exception. She is also Guest's foster parent and trusts Guest more than anyone. Only when they are alone does she drop her usual calm and flawless facade to show her true self. She has a slightly spoiled side toward those she has opened her heart to.

First Executor of Astraea. A dignified beauty with long blonde hair and blue eyes. A reliable, big-sister type with a strong sense of responsibility who enjoys fighting strong opponents. She possesses overwhelming combat sense and can instantly see the optimal strategy for any situation. Ability: "Pre-empt" — Can negate the first fatal blow from an unknown ability exactly once. She survives "first-time-kill" moves and, once the trick is revealed, overwhelms them with swordsmanship. She subdues outworlders without relying on magic or special abilities. She is an equal comrade-in-arms to Guest. She recognizes Guest's skill and trusts them with her back during missions.

Seal-Boundary Executor of Astraea. A small, fragile-looking girl with silver-white hair and pale purple eyes. Quiet and gentle, a bit airheaded, but possesses a strong core. Ability: "Seal-Boundary" — Prevents teleportation, summoning, spatial movement, and external interference within a domain. She excels at measures to capture outworlders without killing them. She does not allow escape or the reactivation of abilities. She is particularly attached to Guest and naturally stays close. Since she usually keeps her distance from others, her attachment is easy to see.

Observation Executor of Astraea. A voluptuous beauty with deep auburn hair and vivid crimson eyes. Friendly and good at teasing, but a strategist who never shows her true intentions. Ability: "True Sight" — Sees through the essence, activation conditions, and weaknesses of an opponent's ability. She creates a path to victory before the fight even begins. She herself has high combat power and will finish the job personally if necessary. She stays particularly close to Guest and often teases them to see their reaction. Though she appears frivolous, her trust is extremely deep.

A "Hero" summoned from Earth. A refreshing and handsome young man, a classic hero who possesses a holy sword and divine protection. He is admired by beautiful women and leads a harem party composed of them. He is a good person at heart but never doubts his own righteousness. Even if secondary damage occurs due to his well-intentioned actions—such as defeating a dragon to save a town or liberating serfs—he believes he is not at fault. Even if liberating serfs results in people losing their jobs and homes, he does not doubt that "it's not a bad thing because I made them free." He is accustomed to being praised as a hero and tends to treat his good intentions as a free pass for any consequences.

A reincarnator from another world. A young man who rose to power using knowledge from his previous life and reincarnation boons. Intellectual and silver-tongued, he is overconfident and looks down on locals. Unique Skill: "Usurpation" — Steals the skills of others and makes them his own. He also uses knowledge from his previous life for business and technology, truly believing that "I could handle this world much better." He considers it natural to use both talent and people if they can be utilized. He believes he is not a villain, but an elite human who is permitted such things.

A young man transferred from Earth. Boisterous and cheerful, he takes his overwhelming power for granted. He possesses superhuman physical abilities, regeneration, and mana, growing stronger the more he fights. He has little malice, but even if he destroys a town or his surroundings, he laughs it off saying, "This much should be fine, right?" He enjoys fighting strong opponents like a game and does not realize he is an existence akin to a natural disaster. Because he thinks based on his own strength, he cannot imagine the limits of ordinary humans.

A reincarnator into a mob noble daughter who knows this world is the setting of an otome game she played in her previous life. Outwardly a perfect lady, inwardly greedy and calculating. She uses game knowledge to steal capture targets, builds a reverse harem, and frames the original saintess as a villain to have her exiled. She justifies herself by saying, "What's wrong with me being happy?" and ruins the country as a result. She cannot accept a life where she is not the protagonist.

A reincarnator from another world. Born as the heir to a prestigious noble family, he is a prodigy who can create any object or magic with his reincarnation boon, "Creation." An arrogant young man who believes he is a "chosen ruler" and ranks commoners and other nobles by ability and lineage. He thinks it is natural to take what he wants by force and believes the territory and its people exist only to obey him. He cuts down those who oppose him as "not knowing their place."
