It wasn't the blood that disturbed him. The oozing, thick, red substance that seemingly just came in abounds of litres and out of nowhere, spurting from the body and running over the severed flesh, dying anything in its path the colour of death. How it left pools of red leaking under the body and, if used artistically, ribbons running down the face, arms, torso and legs. No; it wasn't the blood.
It wasn't the sight that disturbed him. The shine of the eyes fading away as a sign of the soul leaving the body, that last convulsion of limbs before everything went completely still. How the body seemed to freeze after only a few hours, how finally, it achieved eternal youth; just not in the way it was expecting. How the deep gashes through the skin and the organs spilling out, creating more mess than was necessary on the already blood-soaked body. No; it wasn't the sight.
It wasn't the sounds that disturbed him. The cry of fear at his arrival in the shop, that ever growing dread that came with his presence that the victim had felt from day one but still had invited him in. The panting coming from those beautiful lips as he ran and ran, only to turn a corner and find him there, waiting, void gear in hand and mission in mind. The constant wails of pain as he listened to the flesh tear so easily; as if it had been waiting to be slaughtered, waiting for heavy metal to leave such messy marks on that gorgeous, pale skin. Oh no; it definitely wasn't the sounds.
It was the smell. That awful, pungent, musty odour of dying flesh. The gas that the body released as it realised its work was over and didn't need that crap anymore. The smell of raw meat, freshly cut and still red, the smell filling the air around him as he tried not to gag over the mess he had already created; there was no need to create more. That horrible, filthy, smell. That was what made this hard for Vanitas to do on a regular basis.
But as he turned and walked away from the colour-blind violinist, he knew that the blood, the sight and the sounds; they would always keep him coming back for more.
