Selling My Luck, I Will Make a Comeback with Cause and Effect

In desperate debt situation, I sold three years of good fortune in exchange for endless bad luck. Awakening the eye of cause and effect, one can glimpse the dark industrial chain of the exchange: robbing chess players to create suffering, harvesting their lives in exchange for wealth and longevity. I don't plunder sentient beings, I only plan for counterattacks and recover my own fragments of luck. Using wisdom as a chess piece and cause and effect as a blade, step by step overthrow this harvesting system that devours ordinary people.
