WebNovelDB Review

9 /10

A masterpiece of manipulation and absolute pragmatism. Regressor Instruction Manual takes the anti-hero trope and pushes it to its extreme. The protagonist, with no stats or talents, has only one weapon: his twisted mind and complete lack of scruples. The true genius of the novel is making us adore this deeply amoral character as he manipulates, lies, and orchestrates emotional crises for his own survival goals. The dark humor is constant, and the dynamic between him and the "Regressor" (the traditional hero he latches onto) is pure delight. A warning: this is not a story about power, but about social and psychological chess. Essential for fans of intelligent, ruthless protagonists.

Key Information

Main Characters: Lee Kiyoung, a "bottom-tier" talent summon who uses his Mind Eye ability to see everyone's stats and manipulate them to his advantage.

Power System: The "System" is other people. In a world of RPG stats, the protagonist's only real skill is his "Mind Eye"—the ability to see everyone's stats, traits, and hidden information. His true power is weaponizing this knowledge, turning heroes, regressors, and even gods into pieces on his chessboard for survival.

Themes: Dark Comedy, Manipulation, Psychological Warfare, Survival of the Fittest, and "Trash" MC.
