INTRODUCTION: THE MANSION.

At the outskirts of Yokohama, in the south, there lay a derelict mansion that was overgrown with ivies and moss and bugleweed.

The wooden doors open. Enter, little ones.

The beautiful somnambulist perpetrates her crimes of her ancestral bloodline by killing, impaling, licking the blood off her fingers as she crushes a heart within her clawed hands. Her story is something that cannot be written down, for it eludes the written language, but rather through oral transmission.

Legends are never forgotten, but so are curses.

No one will come rescue you if you enter this cursed mansion, this ancient chateau that has been established pre-human comprehension. This place has been a palace of annihilation, for those wishing for death. And many have died underneath this roof, whether that be suicide or overdose or starvation.

"I'm telling you, man," A boy's young voice echoes through the wooden hallways, where portraits of ancient, solemn family members looked blankly into transparent space flanked the walls. "This is a really bad idea."

"You always say that," The other one says. He is the one holding the flashlight, the beam hitting the floorboards that creaked ominously underneath their feet. "But you–"

Swish!

They both snap around. Their heart rates start to quicken: a beautiful melody for the cursed ones. The internal noise seems to act as a stimulant, for the ancestors within the family portraits began to look more animated, as though colour flushed their cheeks and lips.

The one without the flashlight laughs nervously.

"See? Nothing," Hiro says. He turns back to the looming hallway, this time noticing the baleful and seemingly starving eyes of the prisoners of the past, locked behind a wooden frame and glass pane. "This place is just like every other so-called 'haunted place'."

"Is it, though?" The other boy, Aiku, anxiously chews on his lip, eyes flickering to the ceiling where he notices mould blackening the wood. "This place is known for..."

"For what? Say it."

"Well, housing a vampire," He quietly murmurs, the flashlight shaking in his hands. He walks forwards, into the open cavern of the house, into the darkness where no amount of light penetrates the blackness. "There are folklores about this house about how she's still aliv–Hiro?"

Hiro is gone. Aiku feels his palms grow wet with sweat as he staggers backwards, his back hitting a door that opens–he falls back with a thud, a noise that throws dust up into the air and pain to surge through his head. He groans, feeling his eyeballs spin as he blinks through the black spots polka-dotting his vision. His hand gropes around the floor for the flashlight, and when he grabs it in his hand, he hears a skin-crawling, hair-raising scream reverberate through the entire mansion.

"HIRO!? IS THAT YOU HIRO?" Aiku stumbles to his feet, grabbing his cap that had fallen off his head before sprinting across the foyer where two podiums of gargoyles rested, their uncanny stone eyes locked into another world where stone statues were alive and moving. He ignores them as he skids to a halt, looking up the stairway where there was a woman standing, dressed in all black with a serene smile on her face. Half her face was covered in shadows, obscuring him from the lethality of her beauty. "Did you hear that scream?"

"Oh, of course," She says, making her way down the staircase with her hand hovering over the dusty handrails. Her voice is hollow, as though a blown note from a flute, teetering on the edge of breaking and snapping in half. And it does, in the form of a giggle.

"Who're you, anyways?" Aiku snaps, taking a step back when the woman finally touches the ground with her bare feet.

"I?" She says, the smile barely faltering. "I am the owner of this place."

"The landlord?"

"Something like that," She says, and then the moon finally shines its light on her face.

Blood splattered across her cheek, covering her chin, and dyeing her teeth a raw red as she grins; sharp canines still seemingly warm from the artery that had been stolen of its vital liquid.

Aiku screams, before it's cut short.
