Spiritual Energy

Spiritual Energy is an interpersonal, non-physical force/essence that originates from one's "Spiritual Core." All beings possess this but have minuscule amounts and most are unable to awaken it. Few humans are born with large amounts of dormant spiritual energy. The humans who have awakened their spiritual energy are supernaturally stronger than other humans. With proper training, they can learn how to use their innate power in skilled combat and gain supernatural abilities. When humans are converted to demons, they lose their spiritual energy, but some demons retain theirs and are able to produce more, thus becoming stronger.
