He was once the military king "Shura", codenamed "Dragon Blade", who made the dark forces around the world fear him. During a mission, he was seriously injured while rescuing his comrades and retired from the army. He wanted to live an ordinary life anonymously, but he discovered in an accident that his sister, who died tragically five years ago, had been transformed into a cold-blooded killer, and the man behind the scenes was the senior executive of the "Nighthawk" organization that he once guarded to the death.
In order to save his brainwashed sister, he returned to the world. Little did he know, a bigger conspiracy was quietly brewing - his former comrades were killed one after another, his old troops were hunted down, and even his most trusted brother was facing betrayal. It turned out that someone regarded him as the biggest threat and carefully laid a dragnet.
With his extraordinary fighting skills and military literacy, he resolves crises time and time again. But the enemy's real purpose is to completely darken him and turn him into a killing machine in their hands. When a life-or-death decision is placed in front of him, and his sister's dagger is pressed against his chest, he must make a choice: give up resistance and fall into darkness, or overthrow the entire decadent empire with one person's power?
The ultimate showdown about trust and betrayal, light and darkness, begins here.
