The Mad Immortal

A Devil escapes the depths of Hell seeking a new life. But reincarnation goes wrong and he wakes up in the weak child's body. Worse, he remains trapped deep within, forced to watch as a new personality lives the life he had dreamed of. Young Grey's fate is completely rewritten. Branded as the Primordial Sinner, he is condemned to a life of agony. Torment, conspiracies, exploitation, and betrayal... To anyone else, it would be a living nightmare. To Grey? Just another Monday. How can he live in peace when he can't even trust his own reflection? Only by crushing every trial in his path can Grey carve out his own road to happiness. — Description from novelcodex.org
