Heavenly Bound Between Light and Darkness

Niki was once a feared assassin in his era, a warrior everyone dreaded. The devil gave him two choices: become a sinner in exchange for bringing his sister back to life, or rot forever in darkness and misery.

Sunghoon is already the devil's right hand-the most dangerous demon. He was ordered to kill the Golden Heir, Sunoo. If he refuses, he will die, because the devil is the only reason he is alive. This curse forces him to obey every command.

Jay is the bravest heavenly knight, tasked with guarding heaven from invaders-whether they are sinners, demons, or evil souls. His presence radiates authority, and all heavenly protectors stand by his side, as he carries the aura of a commander.

Jungwon is the priest, a respected angel who also serves as the messenger of the eldest.

Sunoo holds the greatest role in heaven. He is the last angel with golden blood, since all others like him were killed in the war between light and dark. Without him, heaven will fall, and darkness will rise. The devil's main goal is to claim Sunoo's heart, for it is the key to his strength.

Heeseung and Jake are protectors of heaven. Heeseung holds the gift of defense, creating a massive shield that surrounds heaven like a glowing sphere, keeping it safe from danger. Jake is the weapon-the raw power to wipe out everything. Both come from families born to serve heaven, carrying generational gifts. Yet, their bond will not end well, as their paths are torn apart by misunderstanding and betrayal.
