Waking from a seal after 1752 years, Ryuga Xicor discovers that the world he once knew now despises him. He is seen as the man who killed the former Grown Princess. Unknown to everyone, Ryuga had a secret relationship with Irla, which her father, the Emperor, completely disapproved of.
Instead of clearing his name, Ryuga challenges the Nexus Empire and its leaders, The Primes, who are the pillars of the empire. He hides his true motives under the guise of a villain.
Little does he know about the secret behind his kind's existence and eradication, or even more profoundly, the mystery surrounding His Very Existence.
