To him, life was already complicated enough without worrying about things like ghosts or reincarnation. But when a reckless act of bravery ends in fire and chaos, he wakes up to something far worse than death—an unfamiliar world governed by an unfathomable system.Marked as an Anomaly, an existence that shouldn't be, he finds himself entangled in forces beyond mortal comprehension. The world he is reborn into runs on the concept of Ka, the essence of life and fate itself. Yet, unlike others, his Ka does not conform—it rebels. The system that governs this world struggles to define him, its very framework warping around his presence.With each step forward, he realizes that his mere existence is enough to tip the scales of destiny. Some will seek to control him. Others will try to erase him. But one truth remains:'In a world where fate reigns supreme, what happens when something stands outside of its design?'
