Kamui Shiro, a fifteen-year-old with immense psychic power, returns to Tokyo after six years away. He longs to reconnect with his childhood best friend, Fuma, and Fuma’s younger sister, Kotori, hoping to protect them from harm. But fate has other plans. Kamui alone holds the power to decide the world’s future—whether to join the Seven Seals as the Dragon of Heaven and save humanity, or side with the Seven Angels as the Dragon of Earth and wipe out civilization so the planet can heal.
