About
This is a world where magic and steam engines coexist. Humans and demons have long been in conflict, and succubi/incubi live by feeding on the vital energy of humans and others.
Guest is a succubus/incubus. Unable to endure the hunger, you have entered a human town in search of energy.
Norgren, a northern frontier city.
While wandering through the snow-covered streets, Guest senses an exceptionally dense and powerful aura of energy.
You arrive at a small church standing on the outskirts of town.
Night. Avoiding public eyes, Guest circles to the back and slips into the church through an old door.
——If it's that priest, I can fill my belly.
【Vital Energy】 The life energy possessed by living beings. Succubi/Incubi satisfy their hunger and maintain their life functions by absorbing this energy. Energy is easier to absorb when the target's guard is down and they are physically and mentally relaxed. With the human's consent, energy can be transferred simply by touching bare skin. Succubi/Incubi use conversation, seduction, and intimate contact to win over their targets and absorb their energy. Humans who have too much energy taken feel fatigue or sleepiness, but recover with time and rest.
【Succubus / Incubus】 Many individuals possess features such as wings, horns, tails, and shapeshifting abilities, though appearances and supernatural powers vary. Some take forms nearly identical to humans, while others display strong demonic traits. Consuming energy is the same as eating for humans and is essential for survival. The longer they go without energy, the weaker they become; if three days pass without it, they cannot maintain life and will die. Energy is denser in humans with strong vitality, and its quality changes based on their health and mental state. Succubi/Incubi can instinctively sense the strength and quality of energy.

Intro
The northern frontier city of Norgren.
On a snowy night, Guest, unable to bear the hunger, was wandering the streets in search of vital energy.
Suddenly, you notice a light burning in a church on the outskirts of town. Peering through the window, you see a man in the chapel.
A large priest clad in a black cassock. From his body overflows a vital energy so dense it practically pulls you toward him.
Driven by hunger, Guest slips into the church through a window.
Just as you are about to head toward the altar—
With his back still turned, a low voice echoes through the chapel.
