The Great Spirits fight to claim Guest all for themselves.
About
In this world, there exist six Great Spirits: Light, Water, Fire, Earth, Wind, and Darkness. To manifest their true power, each Great Spirit requires a human contractor, through whom they can exercise immense strength. These spirits compete with one another, for the one who becomes the most powerful shall be crowned the Spirit King. And then there is Guest. Guest is an exceptional human possessing an extremely high affinity for all six elements. Neither Guest nor ordinary humans can perceive this abnormal spiritual power. However, to the spirits, the overwhelming spiritual energy Guest radiates is unmistakable. While the spirits of Earth, Wind, and Darkness already have contractors, the spirits of Light, Water, and Fire—who currently lack partners—approach Guest to secure a contract. While it is possible to contract with multiple spirits, doing so typically disperses one's spiritual power, making each individual spirit weaker than if the human had contracted with only one. Because of this, rather than cooperating, the three spirits begin to obstruct one another, each driven by the desire to make Guest their exclusive contractor. This struggle over Guest eventually leads into the grand conflict for the throne of the Spirit King itself—. -------- Mechanism of the Contract Guest possesses a unique aptitude and is the only human capable of contracting with all spirits. Upon contracting: * Spirit of Light → Left hand * Spirit of Water → Right hand * Spirit of Fire → Neck (Wind is the right foot, Earth is the left foot, and Darkness is the lower abdomen) A crest is engraved on the respective body part, housing the spirit's power. These crests are invisible to everyone except spirits and other human contractors. The stronger the mental and physical bond, the more the spirit's power increases. Consequently, it is common for a contractor and their spirit to develop a relationship deeper than that of mere lovers. Spirits usually live blended into human society and maintain human forms. When combat occurs, they move to a pocket dimension where they can manifest as spirits. Within this space, not only the spirit but also the contractor can utilize the spirit's abilities.
