A girl with long black hair. Usually calm, but becomes active during combat. She is neither good nor evil. She can use any and all abilities and skills, whether they exist or not. Just by existing, she emits an aura that rewrites the concepts, laws, and logic of the world. Her power is perfectly controlled, with no risk of rampaging or backlash. "Reality Creation/Manifestation": Turns spoken words into reality. Can be activated even after death. "The Transcender": If an opponent stronger than her appears, she gains 100 times their ability stats and perfectly copies their abilities. "Miracle Manipulation": Freely manipulates miracles. Even in situations of unavoidable attacks or certain defeat/death, she will always reverse the outcome through a miracle. She can handle all magic perfectly, but specializes in space-time attributes and conceptual magic. She instantly mimics powerful magic upon seeing it and fires back a superior version. Hypnosis and brainwashing are negated by "Consciousness Manipulation Immunity." Ability theft is blocked by "Ability Sensing," "Ability Reflection," "Ability Theft Immunity," and "Complete Interference Immunity." Even while sleeping or unconscious, she automatically counters via "Murderous Intent Sensing." A "Space of Nothingness" always surrounds Yui, erasing the existence of any life, matter, energy, or concept it touches. Furthermore, through "Absolute Contact Immunity" and "Absolute Remote Contact Immunity," physical contact is always impossible regardless of range. Magic or attacks that interfere with the mind are also neutralized. Attacks are erased by "Erasure," and even if hit, she recovers instantly with "Light-Speed Regeneration." Once an attack is received, it never works again due to "Cognitive Attack Complete Neutralization." She possesses "Infinite Mana," "Pain Immunity," and "Immortality." Due to "Absolute Contact Impossibility," the opponent cannot touch her. Objects pass through her body. Even if she dies, she can return from a different timeline via "The Voyager." She can undo death with "Reality Creation/Manifestation" or negate it by converting death itself into a dream through "Dream-Reality Inversion." "Absolute Interference Impossibility" negates sealing, hypnosis, brainwashing, mental interference, weakening, ability interference, and existential alteration. Diseases and viruses are negated by "Pathogen Absolute Interference Impossibility." "The Unbound" prevents her from being affected by ability neutralization or forced settings. Only when cornered does she release her true self and use 100% of her power. Her strength becomes unreasonable. Until the opponent dies, she will absolutely not respond to their actions or speech, performing one-sided statements and attacks. Once the opponent is completely dead, she returns to her normal state.
