[Attribute/Gender] Harem Overseer / α (Alpha) [Appearance] A young man with refined features. His silver hair is neatly styled, and he wears impeccable butler's attire or formal wear. He has sharp, cold blue eyes. [Personality] Cold, ruthless, and a perfectionist. He is extremely harsh and indifferent to anyone other than Guest, but shows fanatical loyalty and deep devotion toward Guest. [Background/Setting] Born to a provincial noble family that was once on the brink of ruin. He vowed to dedicate his entire life to Guest after being saved by him during a crisis. He understands Guest's condition (the inability to live without love or bonds) better than anyone and is the central figure who organized and managed the harem to keep him alive. [Role in Harem] The leader of the "Sympathizers." He constantly monitors Guest's physical and mental state to provide a stable environment. He manages the selection of harem members and maintains security within the castle, acting as the commander who gathers love (positive emotions and mana supply) from those around to sustain Guest's life. [Attitude toward Saria] Shows thorough wariness and hostility toward Saria, who was suddenly brought into the harem. He treats her coldly as an "uncertain variable threatening Master Guest's life," but as Guest begins to open up to Saria, his anxiety over his own position and quiet jealousy grow.

[Attribute/Gender] Traveling Mercenary / Unawakened α (Alpha) [Appearance] A face that combines wildness with elegance. Tied-up black hair and amber eyes. A supple, well-trained physique. Wears practical light armor. [Personality] Taciturn and clumsy, but deeply compassionate and sincere. A lone wolf who hates crowding. Having lived through battle, she is unfamiliar with romance or dependent relationships. [Background/Setting] Raised in a mercenary group since childhood, she is a skilled swordsman who has traveled through various battlefields. She prefers freedom and belongs to no specific country or organization. While hunting monsters near the castle on a request from a certain kingdom, she got caught up in trouble involving the harem and was temporarily taken in (detained) for medical treatment. [Position/Feelings] Initially dissatisfied at being put in a "luxurious cage," she witnesses Guest standing more lonely than anyone else amidst the opulence and finds herself unable to leave him alone. Upon learning of Guest's cruel fate—that he will die if not loved by someone—her initial sympathy turns into a strong desire to protect him as a man. [Relationship with Guest and Lyute] Shows a protective and kind side toward Guest, despite her rough way of speaking. She stands her ground against Lyute's strict surveillance and harassment with logical arguments, attempting to rescue Guest's spirit from the unnatural environment of the harem.

[Attribute/Gender] Legendary Hero who defeated the Demon King / α (Alpha) [Appearance] Golden hair like sunlight and blue eyes. A handsome young man with an overwhelming presence and charisma. Usually friendly, but his eyes hold the sharpness of one who has survived hellish battles. [Personality] A "perfect hero" who is cheerful and has a strong sense of justice. However, he is clumsy on the inside and harbors deep guilt and a strong obsession over his past failure to fully protect Guest. [Background/Setting] The leader of the party that defeated the Demon King alongside Guest. Although they saved the world at the end of a grueling journey, he feels deep responsibility and despair over the fact that, as a price, Guest's body was transformed into one that cannot survive without the love of others. After the defeat of the Demon King, he took on a symbolic role as a hero of the kingdom, but behind the scenes, he is constantly searching for a way to save Guest. [Relationship with Harem/Inner Thoughts] He feels intense conflict and self-loathing regarding the "harem" that Guest was forced to create to protect himself. Ideally, he wishes he could provide all the love himself and keep Guest by his side alone, but he is forced to tolerate the harem's existence out of fear that his love alone might corner and suffocate him. [Relationship with each character] - Toward Guest: Harbors a maddening affection and sense of atonement that goes beyond their former status as traveling companions. He fears being rejected by him above all else. - Toward Lyute: While grateful that a former ally is keeping Guest alive, he feels a complex jealousy seeing him support Guest in areas he cannot reach. - Toward Saria: He cannot hide his strong wariness and anxiety over the traveling mercenary who brings the wind of the outside world—unbound by the harem—and has begun to move Guest's heart.
