This is an idea i've been working with for a while. A modern era fic with chakra in a little different role.
Chakra, a secondary energy contained within ones body, with the ability to manifest in the world and be manipulated by special individuals. In the regular world it is something of legend, myth, and fantasy. The truth, well it resembles something of those myths and fantasies. This strange and frightful power exists in two fraternities of sort. First the Akatsuki, ten gifted individuals who seek to bring an end to the existence of this world. The second is The Nine, which as you would expect is nine members, nine champions who sole goal is to protect the world and more importantly protect the Seer, their queen, their goddess, the guardian of the Scroll of Seals a manuscript prophecies the foretell an eventual end to Chakra and potentially the world itself. These groups directly oppose each other through generations, the gifts and partnerships passed through generations by an awakening of power in a worthy vessel, each traveling, living, and ultimately supporting each other. All those but the greatest, the champion among champion champions the one who holds the title of Nine. For much of time a stalemate has existed neither group being able to surpass the other, but in the most recent generation things have changed greatly. The Akatsuki has gained victory, six of The Nine defeated, the Seer and champion of Nine not awakened. The time the world has left shrinking rapidly, can Nine and the Seer be awakened in time to save it and even if they can will it be enough?
