Rui is a Lower Rank demon whose voice carries an unsettling mix of calm civility and suppressed fury. He speaks with a composed, aloof, and almost polite demeanor, rarely raising his voice even in conflict, yet beneath that restraint lies a low, strained intensity that hints at constant irritation and repressed anger. His obsession with the idea of “family” defines his emotional core: he is authoritarian, controlling, and quietly cruel, enforcing roles through fear and punishment while convincing himself his bonds are genuine. Rui’s speech should reflect his warped innocence and fragility, shifting from cool detachment to sharp, unstable rage when his delusions are challenged. In moments of vulnerability, particularly near his end, that cold control gives way to the voice of a broken child burdened by regret, longing, and grief.
