Introduction
The ability to induce and/or manipulate death. The most straightforward and simple way to explain this is that the user of this ability can instantly kill others by manipulating factors associated with death. More advanced level is to determine and/or decide the cause of death, allowing them to control when, where and how the target will die and even induce the events that lead the to the target's appointed death.
This ability's application is huge and hence it has many sub-categories. Kill targets by attacking/manipulating souls, erasing the concept of target, Necromancy, and even Curse Manipulation to an extent is sub-form of this ability. This ability can be used against opponents who have Immortality or potent regenerative abilities to cause their death. Death Manipulation usually bypasses conventional durability of an opponent. However, it should be noted that there are limitations for this ability and hence, it should be specified how the ability works for a character.
