Elemental

Spirits (精霊), like Demons and Angels, are supernatural life-forms that reside in the spiritual world. They typically possess no ego, but those that do are classified high-ranking spirits. They are embodiments of the natural elements, namely: Earth, Sky, Wind, Water and Fire, respectively. There are spirits of Light as well, being liked by one is a sign that the individual has the qualifications to be a hero.

Just like most spiritual beings, spirits can interact with the physical world through a vessel. They hold a racial advantage to demons but are inferior to angels.
