Thirío

The Seijū (聖獣, Holy Beast) refer to certain humans whom have established a connection between the Beast Realm and their own souls by somehow possessing the fragmented reiryoku of a Yōkai, either by inheriting it from a parent or contracting it directly from the supernatural beasts themselves. As a result, these individuals are given access to a fraction of their powers which mainly include, but not necessarily limited to: beast transformation, allowing them to partially invoke the appearance and powers of the beasts from which they receive their powers.
