In a world where royalty are the protectors of humanity with the ability to summon power from the Sun, the Ocean, and the Seeds of the Earth; this ability is called Shōkan.
Those who can summon light, energy, fire, and radiation are from the Hikari Tribe; the tribe of the sun. Those who can summon various plants and influence them at will are from the Shido Tribe; the tribe of seeds. Those who can summon sand, water, and salt are from the Umi Tribe; the tribe of the ocean.
Over 400 years ago, humanity's existence was threatened by a horrifying evil; the Hybrids. This is when some of the most noble men and women realized their true Shōkan potential and took their place as protectors.
With shōkan abilities being passed down from father to son, humanity was able to overpower the evil that threatened their existence. Those who were entrusted with shōkan abilities became the eternal protectors of humanity, thus making them royalty.
The monstrous hybrids that once threatened humanity are now few in numbers. Within the last 15 years all hybrids have nearly become extinct and the worse of them called "The Crimson Bloods," have been completely wiped out, at least that's what we thought.
