In this world there are Two groups,The humans and Demons.
But when a new group starts fusing them into humans creating hybrids things don't go as planned when the flame demon king Ifrit fuses with a young boy and destroys everything they've worked for breaking the seal between the heavens and the earth.
Oblivious to the new world and believing in his dream young Kevin,the vessel of Ifrit wishes to find all other vessels bringing them together to stop the occult group and prevent the rising war between the four factions.
