Ryuusei World Actor: Gaslight Bullet

Schonheit, a member of the anti-monster organization called The Order, receives a special mission.
A town is under siege, people are being murdered, and women are being violated…
and the secret of “humankind” is slowly revealed.
Deeply involved is the relationship between the “Celestials” and “Demons” that persists only in legends…

The girl opens her eyes in a desolate world, and hears "your" voice from in front of the screen.
You can direct her actions, help her solve mysteries, evade dangers, and find a way to leave this place. Of course, you could also choose not to do so, or even worse, deliberately guide her to death... Just kidding, you surely wouldn't do that, right?

In a distant kingdom ruled by ambition and fire, an aging monarch dreams of expanding his legacy. Obsessed with conquest, he sends his sons to subjugate the neighboring provinces — once peaceful lands now protected by a mysterious and fiercely resistant coven of witches.
 
But fate has no loyalty to bloodlines.
 
During one of these brutal campaigns, the king’s eldest son — his pride, his heir — falls in battle, slain by arcane forces that no sword can match. Grief soon turns to rage. And rage calls for vengeance.
 
Desperate to strike back, the king seeks out a warlock long banished from the royal court. The warlock offers help — but not the kind the king expects. Through a dark and forbidden ritual, he raises the fallen prince from the grave… not as a man, but as something else. Something hungry. Twisted. Unnatural.
 
Now, a creature of lust and undeath walks the earth once more, driven by a primal desire to defile and destroy the witches who ended his life — one coven at a time.
 
This is a tale of power, corruption, forbidden resurrection… and the sinful magic that binds them all.
