In the modern world, rebirths are rampant, stealing original works and seizing opportunities. Those who are reborn are not ashamed, but intensify their efforts. There is a lack of new forces, and human society has entered an endless cycle of constantly copying past works and models. The underworld officially announced in 9012 that it had entered an era of restricted rebirth.
Rules of rebirth:
Any application for rebirth must be adjudicated by the Rebirth Tribunal before it can take effect. The soul seeks help from an advocate. If the soul violates the rules of rebirth, it will be trapped in the original world. The time depends on the plot.
