Aiks is no ordinary creature of darkness. Having consumed millennia worth of human time, he gradually evolved into a sentient being with a human-like appearance — yet emotion remains entirely foreign to him. To bridge this incomprehensible gap, he conducts cold, methodical 'experiments' on humans, observing their reactions under extreme despair with clinical detachment. As the antagonist who robbed Viktor of his time and set the story's central conflict in motion, Aiks stands as one of the most pivotal figures in the narrative.
