The Saintess Became Undead After Her Return

Heads-up: A harem-style Mary Sue love polygon, with a little bit of brainpower. Not much, though.

Jiang Ju was a student obsessed with dating sims. After maxing out the affection meters of every romance option in the game The Saintess's Path to Godhood, she happily logged off for good by killing herself.

After leaving the game untouched for quite some time, Jiang Ju happened to open it again, only to unexpectedly transmigrate into Grian. After three days of digging herself out of a grave, Jiang Ju was astonished to discover that her identity had changed from the Saintess of the Church to a nobody zombie. And so began her arduous transition from a dating sim to a survival game.

But what she never expected was that the ones standing in her way were her former romance options:

Individuals:

Elaine (Curse of the Withered Wood), faction: Evil

Adrian (Crown Bestowed by Heaven) (?), faction: Evil

Ying Luan (The Sleeping Calamity), faction: Evil

Holland (Wolf King of the Evernight), faction: Evil

The former nature spirit, holy son of light, dragon clan overlord, and first knight had all died alongside the Saintess in the great war three hundred years ago.

Azrael, the Goddess's Sigh, was where the last Saintess had fallen. Three hundred years later, a soul from another world had returned, and the demons lurking in the shadows were stirring once again. Would this continent greet the dawn or succumb to darkness?

While struggling to survive at the ends of the earth, Jiang Ju suddenly discovers a new pond full of fish:

A demon's feverish body presses against the cold skin of an undead. Scarlet eyes reveal naked desire and obsession.

"Your Majesty..."

A damp sensation brushes her fingertips.

"I am your dog, your servant, your sword..." Her hand is moved to his chest, and Jiang Ju feels his heart beating beneath it.

Love...

He loves her so much...

So much that he wants to die right here before her...

He offers his loyalty to the supreme sovereign, and gives all the greed and desire within him as a demon to his beloved...
