Acausality

Yukari Yakumo (Touhou Project) was able to see through Keine Kamishirasawa's ability to eat the past itself.

Introduction

Acausality is when a character lacks conventional causality, varying on the scale they lack on. For some characters, this means they don't exist in the past or future; for others, this means defying all logic and acting with complete disregard for any causality.

Types

Type 1: No Past: Users of this type have no past, and thusly any attempt to change or see their past often cannot work.

Type 2: Free Will: Users of this type have no future, and thusly any attempt to change it or see their future often cannot work.

Type 3: Irregular Causality: Users of this type exist on a different and irregular level of Cause and Effect, different to our own. This grants them resistances to abilities that rely on conventional cause and effect such as: Causality Manipulate, Fate Manipulation, Precognition, and similar abilities.

Type 4: Causality Immunity: Users of this type are outside of Causality. Any attempts of a person or ability that functions in a casual system cannot traditionally harm the user as the attack will be bound within a system the user does not exist within (Note: Users with Type 3 Conceptual Manipulation would be able to affect these users)

Type 5: Causality Transcendence: Users of this type do not function on any level of causality and are transcendent over Cause and Effect. Any attempts of a person or ability that functions on a Cause and Effect system cannot traditionally harm the User as neither the cause or effect will initiate. (Note: Users with Type 2 Conceptual Manipulation would be able to affect these users)

Note: This ability can correlate with Time Paradox Immunity however, the effects aren't the exact same.
