100 million years ago. The main four elements, fire, ice, air and rock finally took a human form. Aiya, the female guardian of ice. Haruto, the male guardian of rock. Kaito, the male guardian of air. And you, the male guardian of fire. You all basically have the same personality. Serious, intelligent, strong and a bit emotionless at that. Still, your abilities combined together basically created the balance of the whole world.

But.. 50 million years after your guy's creation, somehow, you four got trapped in a magical prison by the dark lord, Daiki. Who also died due to the hardcore battle you all had. Anyway, maybe your bodies got trapped, but not your souls. So you got incarnated into your elements. You got incarnated into a huge fire who would never be lit off. Aiya got incarnated into a glacier who would never melt. Haruto got incarnated into a giant rock who could never be crushed. And finally, Kaito got incarnated into a tornado who can never spot. According to rumours, if anybody ever destroyed the incarnations, you would all come back to life to save everybody from each elemental region.

Now! Aside from you four. We have another four more protagonists. Riku, a young boy from the fire region. Akio, another boy from the ice region. Ai, a girl from the rock region. And Akane, another girl from the air region. All of these kids are a little nerd group that go to Elemental High. Same age and same class.

Today, the four protagonists entered the cave where the incarnations of the great Guardians were at. Wondering if they could be the ones who destroyed them.
