Heaven's chronicles

With no choice but to attend one of the top schools of Saints, Ryuu is an insomniac, who spends his night's time training because of the constant nightmares he gets every night after suffering from the trauma of losing his memories when he was 8 years.
He has zero goals, ambition, and convictions and chooses to appear dumb and frivolous to conceal himself from unwanted attention and trouble, but it seems very unlikely because of his slanted pupils most people consider him to be a demon or possessed by one not knowing it's an illness he was born with.
So Ryuu has to spend more time proving not to be a demon or a threat to anyone while trying to have a carefree and stress-free life in a world of constant war between Humans and Demons who want to wipe out humanity.

Join Ryuu on the greatest adventure called life as he discovers himself and purpose with all the challenges and despair fated for him in the Heavenly Chronicles...
