• Yokai Relinquishment - It is a dangerous powerful act for Yokai Shrines. What this does is that it takes away the yokai status, powers, and the ability to change into their yokai counterparts. It turns them into a human. But the cost? Emotions are taken away. Only for a vessel to walk adrift across the Earth. The only place to do this is at Tenshi Shima (Angel Island) and Ryuu no Shima (Dragon Island). This act is more of a forced relinquishment for yokais who have committed atrocities. Total Relinquishment must be done through Ujuukyo Practices.
