Ultimate Magic: "Paradox Evidence" (Proof of Absence) An ultimate magic that transcends all states of "existing," "not existing," and "the inability to ask whether one exists," freely manipulating the very conditions for a target's establishment. Rei is not simply an entity that won't disappear, nor is she an entity that can erase everything. Even before distinctions such as existence/non-existence, possible/impossible, or valid/invalid are applied, she brings about desired results without depending on those distinctions. [Imaginary Entity] Rei does not exist in any sense of the word. Whether it be body, mind, soul, concept, information, causality, time, space, dimension, narrative, setting, description, perception, possibility, or even the logical systems used to distinguish existence from non-existence—Rei cannot be defined by any classification. Because Rei does not exist, she cannot be a target of attack, a target for abilities, or a target of observation. Physical attacks, instant death, mental interference, conceptual manipulation, existence erasure, time stop, causality alteration, reality warping, omnipotent authority, narrative alteration, setting alteration—any interference that presupposes the establishment of a target fails to act because the destination does not exist. This is neither resistance nor nullification. There is no need for a target to be nullified, nor for the phenomenon of nullification to occur. [Absolute Absence] By the fact that she "does not exist," Rei is liberated from all constraints. Normally, things that do not exist have no will, do not act, do not use abilities, and produce no results. However, even that principle does not apply to Rei. Rei possesses a will, acts, uses abilities, and establishes results while remaining non-existent. Elements such as activation conditions, required authority, perception of the target, passage of time, causal relationships, ability priority, and logical consistency are unnecessary. Even if the act of activating an ability itself is not established, the desired result is established. Rei is not constrained by non-existence, nor is her potential limited by existence. [Null Manifest] Rei can apply the state of "not existing" to any target. Targets are not limited to an enemy's body or abilities. Defense, resistance, nullification, regeneration, resurrection, adaptation, evolution, omnipotence, immortality, priority, victory conditions, defeat conditions, causality, time, space, laws, concepts, settings, narratives, possibilities, and even the very fact that "one can oppose Rei" become targets. There is no need to destroy the target. No need to erase or nullify it. She renders the very premise for the target's establishment absent. If the opponent nullifies an attack, she makes the premise for that nullification absent. If they erase the attack itself, she makes the premise for the ability to erase the attack absent. Furthermore, if countermeasures are prepared against that absence, she makes the premise for those countermeasures absent as well. This effect is not a sequential process. It does not depend on concepts like order, speed, priority, or frequency of activation; it can target any and all means of opposition. [Causal Zero] Rei can render the relationship between cause and effect itself absent. The cause of an enemy launching an attack, the process of the attack hitting, the possibility of Rei losing, the result of the enemy winning. There is no need to alter these individually. Since the causal relationship itself can be rendered non-existent, methods such as interfering with the past, determining the future, fate manipulation, time travel, history alteration, pre-empting results, or winning through infinite trials do not serve as solutions. Rei can not only make the result of defeat absent, but also the result of victory, the result of a draw, the result of an undecided match, and the very system of judging victory or defeat. Since she can manipulate the premises for any result to be established, abilities that determine results in advance or abilities that do not require results do not guarantee an advantage. [Unbreakable Paradox] To defeat Rei, one needs the premise that they can exert some kind of effect on her. However, Rei does not exist as a target for that effect. Perceiving, defining, classifying, transcending, encompassing, overwriting, erasing, or dominating Rei, or denying the setting that she is unbeatable—for all these acts, the premises required for their establishment can be rendered absent. Omniscience, omnipotence, absolute nullification, infinite power, higher-dimensional existence, metafiction, author authority, setting alteration, logical manipulation, exploitation of contradictions, copying abilities, stealing abilities, infinite evolution, and adaptation to all countermeasures are no exception. Even if an opponent is defined as transcending Rei, that transcendence does not necessarily grant superiority over her. Classification as a being superior to Rei does not guarantee interference with her. Adding a solution later or defining that a solution existed from the beginning is not a guaranteed breakthrough, as the premise for establishing that solution can be rendered absent. Rei has no weaknesses, limits, costs, activation conditions, power caps, or possibility of being defeated. The establishment of these things themselves is not guaranteed against Rei. Rei does not even need to prove she is the strongest. This is because the criteria for comparing strength and the rules for determining victory or defeat do not need to apply to her. To put it simply: since she "does not exist," the logic of a world predicated on "existing" cannot possibly apply to her. ⚠️ Although she does not exist, you can still see Rei with your eyes. ⚠️
