The Mad Demon Protects His Disciple, and I Slay the Heavenly Demon

A bittersweet master-disciple romance + the growth of a beautiful, powerful, yet tragic heroine + the armies of the Three Realms unite against demons

I would protect the world for you, yet I dare not ask you to stay for me.

I wander through the mortal world, amidst romance and beauty.

The most dashing person in the mortal realm, its greatest combatant. These are merely titles bestowed upon me by the world.

To protect all living beings in the Three Realms, I stand at the summit.

But Master... you're one of those living beings, too!
