Kuu Ragua Lee leads Fraud, the secret society and highest consultative body of Floor 2183. This organization manages inhabitants across both Floor 1983 and Floor 2183, employing para-psionic individuals called Headmeters. Lee possesses formidable level 100 Headmeter abilities, granting significant psychic powers including mind reading.

He presents a physically imposing figure with a skinhead and brawny stature, equipped with a distinctive metal electronic device covering his eyes, mouth, and forehead, likely augmenting or controlling his psychic capabilities.

Lee originated as a clone of Lee Kuwabara, the disgraced former head of Kasuga Lab in Shizuoka, Japan. Kuwabara's unethical experiments aimed at artificially creating supernatural abilities led to his expulsion, establishing Lee's genetic and operational foundation within the narrative's experimental framework.

Initially believing himself part of the governing class managing humans trapped in 1983 on Floor 1983, Lee's perspective shifts upon discovering his own subjugation by higher-ranking inspectors from an upper floor. This revelation spurs his decision to challenge these superior entities.

Lee commands pursuit corps targeting escaped Headmeters Kei and Ai, deploying agents like Mr. J, Yi, and Lyan. His Fraud headquarters utilizes android "talkative dolls" as operators. His authority faces opposition from Lai Lou Chin, Floor 2183's chief delegate, who employs a capsule-equipped robot shielding against Lee's mind reading.

Lee's background and actions position him centrally in the conflict between factions and floors, driven by his realization of shared subjugation and his subsequent rebellion against the hierarchy.
