Negators

Negators (否定者, Hitei-sha) are people with the ability to negate the rules of the world. The names of negation abilities are prefaced with "Un-".

When a Negator dies their ability transfers over to a different human.

The Union and Under are two noteworthy groups that are composed of many different negators.

Types of Negations
Negators come in two types: It's implied these two types can be categorized even further based on their method of activation, with Negator Unrepair classifying Unseen as a self-targeting compulsory activation type. However, these further categories are still unknown.
 * Self-targeting types - Their power can only be used on themselves.
 * External-targeting types - Their power affects anyone other than themselves.
