The Dark Fiend Star falls upon the Nine Provinces. Technology collapses, and the world of the uncanny descends.
The heavens and earth are a stage, all living beings its performers. One song decides life and death; one play commands yin and yang.
In his previous life, he was an elderly opera performer who guarded a collection of rare scripts until he died amid the chaos of war.
In this life, he is an orphan in an apocalypse overrun by calamities, and he unexpectedly awakens the Way of Opera.
Others follow their assigned roles, perform broken plays, and curry favor with the sky screen just to survive.
He possesses a lost orthodox tradition, and every note, gesture, and movement is a method for suppressing evil.
He commands every role, from the male and female leads to the painted-face, supporting, and clown roles, summoning gods, Buddhas, demons, and ghosts with his performances.
A judgment from the sky screen? Then he will perform until he earns a perfect score.
Monsters wreaking havoc? Then he will perform until their souls scatter.
Evil spirits stealing the show and wreaking disaster upon the world?
Then with his very bones steeped in opera, he will hold up the stage of heaven and earth.
The world calls him the God of Opera, but he says only:
I am no actor, and I do not perform to please ghosts and gods. I perform only to protect the everyday life of this human world.
