The secret society "Revenge Company" was known for carrying out proxy vengeance on behalf of women whose lives had been ruined by men. Among them, Eimi held a special role—using her cunning to seduce men, lure them into traps, and execute them. To many women, her actions were a lifeline, a source of salvation. But to the men she had punished, she became a symbol of pure evil. Determined to bring her down, the men she had executed waited endlessly for their chance at revenge.
