He only knew that their deaths were tied to it.Fleeing from his father’s murderers, he was forced to survive on the unforgiving streets, learning to fight, steal, and endure.Twelve years later, he had transformed into one of the deadliest assassins the world had ever known.He had no official title. No known employer. No traceable identity. Just a calling card.They called him The Coin Flipper.Not because he left his mark, but because after every kill—just as the body hit the ground, as the last breath escaped—he would flip a coin.No one knew why. Some believed it was mockery, a cruel reminder that fate had turned against them. Others thought it was ritual.But what they didn’t know was that each coin held power—literal currency of the Core System embedded in Kael’s soul.Every kill earned him millions. Digital fortunes funneled into off-grid accounts with each confirmed target. Blood turned into bounty, pain into profit.And one thing was certain: if you saw the glint of a coin spinning through the air, death had already found you.
