He is the third brother, bewitchingly handsome and known to the world as the Ghost-Faced Young Master, yet he protects her without caring for fame or status.
She is a cold-blooded Shura, reborn amid bloodshed and slaughter, yet gentle toward only one person.
Later, she becomes the greatest under heaven, looking down on all heroes from the heights. Who would not fear or admire her? She is like a god, yet still willing to yield to one person.
She fights and presses forward alongside her closest friends, with whom she has shared life and death, and ultimately reaches the summit.
He stays by her side and protects her, all because of a promise, a small vow from a young boy to a girl.
