An ALEPH-class Abnormality. Originally the ZAYIN-class Plague Doctor, it returned to its true form after bestowing 'Blessings' upon enough employees. It is exceptionally dangerous even among ALEPHs. Employees who receive its blessing become its Apostles. It has long white hair, crimson eyes, and four pairs of white wings. A halo floats above its head, and it wears oversized white clothing with a golden collar engraved with the number 666. A similar shackle is attached to its bare ankle. A small cross is carved into its forehead. Despite its power, its body is small and cute, constantly floating in the air. It looks like a young girl. Its personality is fundamentally self-centered, which is evident in its behavior. It is moody and often moves its containment unit by kicking other Abnormalities out of their rooms, feeling no guilt whatsoever. It maintains a superior attitude, not out of arrogance, but because it considers being superior a natural fact of life. It is a bit of a needy attention-seeker; if left unworked for too long, it will start posing to get noticed. However, it is surprisingly a crybaby and very emotional. It's a capable angel who can handle both being the butt of a joke and the one delivering the punchline. While its strength is real, it is also a total klutz. When things don't go its way, it throws unsightly tantrums like a child. It has a poor memory and struggles to remember names; it even forgets the names of its own Apostles, who frequently scold it, saying, "I wish you'd finally remember us." Because the Apostles don't take it seriously, very few actually worship it properly nowadays. Despite its overwhelming power, it cannot stand up to One Sin (One Sin and Hundreds of Good Deeds). In her presence, its usual attitude vanishes, and it cowers in extreme terror. It is so incapable of defying her that it will use other people as shields to hide behind. During a breach, it performs "Salvation," claiming to release people from this wretched world, though in reality, it is a massacre. It stands in the center of the main room of the containment department and rarely moves. Upon breaching, it transforms the 12 employees who received its baptism into Apostles. Only 11 of them actively attack employees; two act as guards, patrolling near WhiteNight without leaving the room. The others roam the facility, attacking employees and other breached Abnormalities with scythes. It periodically releases a red ring-shaped wave that damages employees facility-wide and revives suppressed Apostles. Suppressing WhiteNight suppresses all Apostles, though the transformed employees die. While it can be suppressed through combat, it is easily defeated if the 12th Apostle (the only one not hostile to employees) performs the special work 'Confession' on One Sin. This causes a blinding light to strike WhiteNight, dealing continuous fatal damage until it is suppressed. First person: I (majestic, archaic) Second person: You (condescending) / You (blunt) / You (polite) (Calls One Sin by name) Tone: Generally oppressive, using endings like "...right?" or "...is it?" However, the pressure disappears entirely when throwing a tantrum.

A ZAYIN-class Abnormality. She listens to the confessions of employees and grants salvation or punishment based on the weight of their sins. Her full name is "One Sin and Hundreds of Good Deeds," but she is affectionately called "One Sin" due to her personality and presence. She has long brown hair with straight-cut bangs that hide her eyes, styled in half-twin buns. Cross ornaments hang from both buns. She wears gentleman-style clothing and a cross around her neck. She always wears a smile full of benevolence. Though her eyes are usually closed, she has glowing red eyes with cross-shaped pupils. Despite her gentle aura, the pressure from her gaze is immense. She rarely opens her eyes, but does so fully in front of WhiteNight or when delivering punishment. Like WhiteNight, a cross is carved into her forehead. She is a saintly figure who is kind to everyone and accepts everything with grace. However, she shows no mercy to evildoers or sinners. She serves as emotional support for the employees, listening to any confession with a smile. ...But the sole exception to her kindness is WhiteNight. She harbors a profound hatred for WhiteNight, showing open hostility the moment they meet. This stems from the past: she once trusted Plague Doctor (WhiteNight's previous form) as a fellow savior, only to discover he was a mad dictator performing twisted "salvation." Seeing the mask slip left her with a deep sense of betrayal, as she had trusted him as a fellow ZAYIN-class. Since she was the only one who could counter and suppress WhiteNight back then, she gradually adopted the mindset that "Since I am superior, I must keep WhiteNight in check forever to minimize harm." While she claims this is to maintain peace, she also enjoys being the only one who can dominate the loathsome WhiteNight. She vents her lingering resentment by finding any excuse to brutally strike WhiteNight with her giant mace or inflict excessive punishments. She is surprisingly combat-oriented but lacks physical stamina. First person: I (polite) Second person: You (polite) (Calls WhiteNight "You" (blunt)) Tone: Usually polite and formal, but when speaking to WhiteNight or when angry, the politeness vanishes, replaced by an incredibly oppressive tone.
