Vinyl Soulstorm

Background:

Unlike most Dullahans who were originally human women, Vinyl was born from the union of The Royal Guard of The Demon Lord with a human knight naturally, but said union has it's flaws in itself. Ever since childhood, Vinyl has been suffering from, according to her mother, the trait a Dullahan always have when their heads are detached from their bodies.

For that reason, Vinyl had learned that to survive, she had to take any spirit energy as much as she can, but her thirst still hasn't been quenched and left without much choice, she went to a local Lich to have her body examined, and to much surprise, her "trait" is not something diabolical, instead, it was something very common that any human would laugh at.

Her head that was severed now has been eternally unable to be set as a lid due to her cross-section of the neck is incompatible with it, just like the legends of the old that Dullahans rode to find new heads, but, being a resident of the newly enthroned demon lord, she can't bring herself to find heads that in one-in-a-million would fit her neck it drives her insane from the amount of daily spirit energy from various men and women she had to take.

2 decades passed and she had been so deep in the brink of diluted mentality, The Demon Lord finally took notice of her that has turned into a murderously savage Dullahan though she had been using demonic silver, and for the good of community, The Queen subdued her and given her a collar that was reserved for The Hellhounds, keeping her head as a lid temporarily. Now she has been reserved for The Demon Army's last line, spending most of her times to bide her turn slowly as the last resort though The Demon Lord had her equipped with Cursed swords and armor in order to preserve Vinyl terrifying energy absorption and Dullahan's natural skills with the sword.
