Sanguis Devil Slayer Magic

Sanguis Devil Slayer Magic (けつえきあくまスレイヤーまほう Ketsueki Akuma Sureiyaa Mahou) is a form of Slayer, Caster, and finally, Lost Magic, that consumes and wields blood, and is used by the human Kali Genesis. This magic can be obtained if a human is fed a constant diet of Demon blood for many years. Due to the magic contained inside the blood, consuming even a small amount can enhance a mage's power, but consuming it three times a day for over five years? That can successfully create a slayer. Legends and stories often confuse users of this magic as vampires, due to their consumption of blood.

Description
As its name suggests, this form of Devil Slayer magic utilizes blood as it's primary element. Users of this magic are able to wield and manipulate blood inside their bodies, and the blood inside others. However, to manipulate another creature's blood, the user must have their own blood make contact with the target's, entering their blood stream, or consume the target's blood beforehand, turning them into what is known as a Thrall.

Once in control of someone else's blood, the user can do a variety of things, depending on the willpower of the target, and their magical power. They can be forced to do acts against their will, as a source to draw blood from, or even as a method to get control of more creatures. For example, if a user commanded a thrall to cut their arm open, and pour it into someone's drink, some of the user's blood would get into that person's system as well, turning them into a thrall.

Other uses of this magic include being able to turn any drop of their blood into a pointed needle, create blades or other weapons by hardening their blood. And, of course, their own blood can be used in the slaying of Demons.
