The Seijū (聖獣, Holy Beast) are a group of Psysis Humans who possess a multitudinous array of superhuman abilities which mostly include, but not necessarily limited to a partial transformation into beastlike creatures; this feat is accomplished by inheriting the blood of the enigmatic Epiphorus, either indirectly through a relative or contracting it directly from the Yōkai himself, which is generally considered an impossibility. Those who possess a more potent amount of the blood of the Yōkai are often granted superior abilities, while those who bear very little connection to him oftentimes find their abilities, or lack thereof, incredibly hard to bloom, which is mostly the case for modern Seijū whom have lost their innate connection to their forefather. There also exists a distinct line of Seijū who are the direct descendants of the first Seijū into which Epiphorus imprinted his mark; these include a select few who showcase a significantly potent amount of the Yōkai's blood, and as such, their powers share the closest resemblance to the Yōkai himself.
