Fate. Destiny. These words will rule the world of those who will decide the future of mankind and the Earth. The Dragons of Earth, or the Seven Angels, stand ready for a revolution that will purify the Earth of the plague that is mankind. The Dragons of Heaven, or the Seven Seals, also step up to defend mankind and prevent the destruction of humanity. And at the center of it all, stands Kamui Shirou. His decision to side with either group will decide the fate of the Earth. Kamui has finally returned to Tokyo to protect his friends, Fuma and Kotori Monou, from the dark times ahead. He will choose his allies and make friends along the way, each endowed with their own unique superhuman powers, to fulfill his destiny and resolve the question: Can the future be changed?
