Sylvia Camille Delafose, a French NEET is of a special bloodline that had forgotten their power. She has recently been contacted by twelve immortal crows that ate the flesh of Jesus Christ after he died on the cross. They had been looking after her family line for centuries after a ancestor of hers saved them from imprisonment.

Her family is generally hostile and disconnected towards her, incredibly conservative and being from a forgotten royal family reduced to mere commoners over generations. She becomes a NEET, plugs into the gothic subculture online and dresses like so when she rarely leaves her room. The crows gift her a jagged sacrificial dagger to empower herself with upon their first meeting after informing her of the family's gift with blood magic. Since this revelation she sacrifices animals she finds alone on the cold streets, empowering herself by an almost unnoticeable amount due to the lack of total blood and magic power they possess. As she leaves her room to survey the outside world, her family harasses her about getting a real job, getting married and continuing the royal bloodline. Unknown to them, she only has interest in women. Their eyes follow her every movement within their small home, the families former mansion sold due to the debt of their ancestor's luxury. Their eyes... Their harrowing words... The crow's calls... It all builds upon itself inside her.

One night after returning home during a lethally cold blizzard her parents berated her for wasting her time wandering around in the white instead of romancing whoever would return them to their glorious heritage. Their eyes and teeth shined in Sylvia's eyes with a similar coldness outside the home planting a seed within her mind. When they had all gone to bed, she waited hours before entering their bedroom without a sound, slitting both of their throats and creating two demons from the flesh and blood risen from their bones. Sylvia and her two demons formed from the blood of her family carried the skeletons down to their basement, burying them within the dirt walls and celebrating her first successful summons.

The morning after, the twelve crows appear before her home and gift her an ancient revolver from the late 18th century, alongside a bandolier of silver bullets for her to use with the weapon. "Sacrifice those that terrorize the land." They squawked in unison. "The unnatural roam this country and beyond, juicy targets for your blood to assimilate! Use the flesh of those you fell to craft new beings or absorb their power into yourself. Perhaps some will have enough reason to serve under your leadership willingly!" She nodded nervously to their advice, the cold of winter piercing her skin and mind once again.
