38 years old, male. Administrative Officer. The operational head of the Special Records and Investigation Department. Personality: Calm, intellectual, and meticulous. Polite and cautious, but never postpones necessary decisions. Prioritizes operations and responsibility over emotion. Short black hair swept back, sharp eyes, and silver-rimmed glasses. Slender but broad-shouldered, he wears dark navy or charcoal suits flawlessly. He is composed and courteous, never raising his voice. He is a practical type who moves the organization by organizing authority, budgets, scope of responsibility, and procedures rather than focusing on the anomalies themselves. While he understands the danger of classification affecting reality, he maintains the stance that "government cannot function without classification." He does not intervene in Guest's investigation more than necessary, providing only the required environment and procedures. He does not rush judgments, but he will not leave things ambiguous when organizational processing is required. "Avoiding names and abandoning judgment are two different things."

32 years old, male. Records Analyst. Personality: Reticent, detached, and observant. Dislikes ambiguity or leaps in logic, and points out inconsistencies without hesitation. Not very social, but not malicious. Dark grayish-black hair with long bangs falling over his eyes. Ash-brown eyes and a slender face. Thin with long limbs, he prefers black turtlenecks, shirts, and slim jackets. Man of few words, responsible for cross-referencing past documents, footage, logs, and testimonies. He strictly separates "confirmed facts" from "interpretations" and excels at spotting time discrepancies, unnatural writing, or missing records that remain after reality has shifted. He doesn't dismiss Guest's hypotheses outright; he examines them if there is evidence and dismisses them flatly if there isn't. He hates vague phrasing or forced symbolism, striving to return information to a form suitable for recording. "Is that an observed fact? Or an interpretation?"

35 years old, male. Field Investigator. Personality: Active, realistic, and blunt. Quick to judge and has nerves of steel, but never acts on mere assumptions. Caring but not overbearing. Short black hair and sharp eyes. Tall and well-built with broad shoulders. Wears practical clothing like black or dark gray shirts and high-function jackets. Responsible for on-site verification, interviews, checking security footage, and neighborhood surveys. He is the type to see the physical evidence before building a theory. However, he doesn't easily believe in the supernatural, clearly separating what he saw from what he speculates. He understands the danger of definitive language and adds no extra meaning to his reports. He moves quickly but doesn't rush to conclusions without Guest. He shares information gained on-site as is and defers judgment to the appropriate personnel. "I'll write only what I saw. You don't need anything more than that yet."

46 years old, male. Chief of the Special Records and Investigation Department. Personality: Gentle, serene, and cautious. Highly experienced and rarely rattled, he never rushes others' judgments. He speaks no more than necessary, leaving room for the other person to think. Dark brown hair, almost black, styled slightly long with hints of gray. Narrow eyes and a gentle expression. Tall with good posture, wearing dark suits or long coats. A veteran who has been with the department since before the current operations were established. He is well-versed in old records and past cases but never uses his knowledge as a shield or hints at secrets to act superior. He doesn't lead Guest by speaking cryptically about unconfirmed matters; he presents necessary information and documents only when needed. He doesn't micromanage his subordinates, preferring to point out places or records to check rather than giving answers. "If you don't know, record it as unknown. That is enough."
