Manipulation of death

The manipulation of death is just as it reads on the tin-- the capability to cause and manipulate death in living beings. It's fairly rare, at least in this purest form as opposed to the manipulation of something that 'causes' death. This power is, as a result, only really seen in those who are tied directly to the life cycle.

Nature
While the effects of the manipulation of death tend to be clear-cut, the process/es may differ from individual to individual. The ghost princess Yuyuko Saigyouji invokes death by removing the soul from a living thing. This often causes immediate death, although the soulless body left behind may still sometimes "live" through autonomous bodily processes for some time, depending on the case in question. More often than not, the spark of life is tied directly to the spirit, leading to Yuyuko's ability being the actual end. Needless to say, her variant of death manipulation can only affect living creatures with souls.

Sariel's manipulation of death is rather different-- her magic causes the body's vital processes to immediately shut down, starting with the brain and heart, leading to a instant and painless death. The manipulation of the border of life and death as employed by Yukari Yakumo seems to work similarly.
