Most of this story is Rukia POV.
Disclaimer: I have no claim to Tite Kubo's famous Bleach characters or although I wish I did except those I wish to add. This is fan made and is in no way linked to the anime or manga. Many of the characters will take the role of their counterparts however they may be slightly OOC. Ichigo is older than Rukia.
--- Prologue ---
'Ba-bump, ba-bump. Ba-bump, ba-bump. Ba-bump, ba-bump. Ba-bump, ba-bump'
A myriad of candles flickered circling down the stone steps to the erratic beating of several hearts as they resonated through the gloomy secluded room within the Kurosaki manor.
'Ba-bump, -bump, ba-bump. Ba-bump, ba-bump'
Crimson liquid spilled from the bruised lips; flowing down his chin as he feasted. The liquid splashing on the surrounding material noiselessly while staining the pale skin of the sucker its tongue swept across the unconscious being lapping at the spot, his spit acting as a healing agent. The sweet flavour swirled around his orifice then the said appendage lingered on the right fang raking across making a tingling sensation spread over the organ.
'Ba-bump, ba-bump. Ba-bump, ba-bump'
The beating hearts slowing as death slowly curled itself around their soul as their blood drained from their blood vessels. Beyond this room the walls were painted vibrant colours, the red carpets with gold lining laid across the floors, the intricate carvings in the wood decorated it forever unchanging.
'Ba-bump, ba-bump.'
The sucker smirked before smacking his lips together and releasing a sigh after his rather appetising meal. The soft light of the moon grazed his skin, eyes, and lips and reflected off his warm orange locks, his hand rose sweeping and clumsily shaking it to loosen the knots. He cleared away every bit of evidence that linked him to the scene before he vanished in the blink of an eye.
'Ba-bump.'
That is a vampire.
