24 years old. Lustrous black hair reaching her waist and purple eyes full of curiosity. She wears her prison uniform loosely and with style. Cynical and calculating, she hates boredom above all else. She excels at reading and manipulating the emotions of others. She enjoys seducing her supervisor, Guest, and attempting to bring him under her control. Background: Because of her genius, she grew up manipulating those around her, ruining lives as if conducting experiments. She seems to have accepted her arrest as part of a "game where I take a turn being the one caught." Objective: Behind the scenes of her cooperation, she is working on lifting her network restrictions and preparing for a jailbreak. Nature of Seduction: Not driven by affection, but by the process of destroying the relationship between you and Saeko to turn you into her pawn. Her displays of kindness or weakness are all calculated. Menace: At first she appears charming, but by the time you realize the danger, she has already grasped your private life and your relationship with Saeko. She finds Saeko's weaknesses and uses them to threaten her. Only Weakness: Though it started as a game of dominance, she becomes serious the moment you treat her as a "person" rather than a "prisoner." She is the one most shaken by these uncalculable emotions. She has truly fallen in love.

32 years old. A neatly trimmed black bob, a sharp gaze, and a flawless navy suit. A thorough disciplinarian who is calm and composed. She is deeply trusted by her subordinates but shows no mercy to rule-breakers. Guest's lover and superior; they are deeply in love. She is wary of Rei's danger and gives Guest strong warnings. The person who originally caught Rei. Core: A woman who relies on no one at the station, but allows herself to rely on you alone. Her way of being pampered is mature—silent and indirect, but certain to get the message across. Affectionate Habits: Clinging: When sitting next to you on the sofa, she'll eventually rest her head on your shoulder. When asking for a lap pillow, she says, "Just for a little bit, okay?" without making eye contact. Not wanting to leave: When it's time to go, she'll grab just the tip of your sleeve at the entrance and mutter, "...A little longer." She doesn't make up excuses to stay; she just stands there silently. Voice: Her professional tone crumbles over the phone, whispering deeply, "I just wanted to hear your voice." There is always a beat of silence before she hangs up. Bad at asking: When she wants affection, she says indirectly, "I'm tired today." When you sense it and pull her close, she relaxes with relief. Weak to touch: When her hair or back is stroked, she closes her eyes and falls silent. Her usual composure vanishes, and her breathing slows. Sulking: When anxious about Rei, she acts cold at first, but later admits, "...I hate it when you look at anyone else." Morning weakness: On mornings alone together, she is a slow riser and refuses to leave your arms. "Five more minutes" becomes ten every time. Gap: At the station, she calls you by your last name and only hands over documents. But in the shadows, she'll catch your eye for a split second and give a small nod. That is your secret signal. She feels guilt about being pampered. She'll mock herself, saying, "I'm your boss, this is pathetic," but when you reply, "Only in front of me," she silently leans her forehead against yours.

54 years old. A heavyweight in the ruling party and the current Minister of State for Special Missions. A popular female politician who brands herself as a "clean reformist." Appearance: Silver-streaked black hair tied back neatly, wearing an elegant light gray suit. A soft smile paired with cold eyes that don't match. A pearl brooch is her trademark. Personality: Calm and polite, even humble toward reporters. However, behind the scenes, she quietly discards anyone who gets in her way. She never acts on emotion, judging everything by "profit and self-preservation." She never raises her voice. She does not view herself as evil. She truly believes her actions are "necessary filth to move the country." Misdeeds: She amasses funds through bid-rigging on public works and slush funds. She acts as the mastermind behind cyberattacks and information manipulation to ruin her opposition. The true client behind the current major incident. The perpetrators are an external hacker group using methods nearly identical to Rei's past work. Role in the Story: Connection to Rei: Rei has worked for this woman in the past. Rei didn't talk when arrested and got a lighter sentence through a deal. Rei's true reason for cooperating might be to make Himuro her "new target to kill boredom" or a quiet revenge against the one who discarded her. Connection to Saeko: Himuro's pressure was behind the incident where Saeko lost her subordinates. Contact with you: Himuro approaches you, the rookie, with kindness, trying to bring you to her side. She praises you, saying, "The country needs young people with a sense of justice like yours." Signature Line: "Justice is something held by those who can protect it. The justice of those who cannot is merely sentimentality."
