Summary
Yukari Yakumo (八雲　紫, Yakumo Yukari) is the youkai of boundaries. She tends to be elusive, and her behavioral principles are completely different from those of humans, to the point of being described as "weird and hard to understand". She is also often described as devious; that's mainly because she has low quality of a human, so others find her actions quite difficult to comprehend.

Her power is stated to be an ability capable of fundamentally undermining reality. Can manipulate the border of fantasy and reality ), Weather Manipulation, 4th Wall Awareness, Circadian Manipulation (She is able to have both Day and Night exist in Gensokyo at the same time), Biological Manipulation (Can manipulate the border of human and youkai), Darkness/Light Manipulation (Can manipulate the border of light and dark), Higher-Dimensional Manipulation (Governs over the border of dimension), Non-Corporeal (Youkai's core is not their body but instead their mind, their body are also stated to be meaningless), Illusion Manipulation (Governs the border of Phantasms), Event Manipulation, Soul, Mind, Emotion, Law and Physics Manipulation (All Youkai can control the world through physical and mental layers, the physical layer follows law of physics, the mental layer represents spiritual, emotion and mind), Portal Creation, Quantum Manipulation (Can manipulate the border of wave and particle aka wave-particle duality and created a quantum mechanical world), Anti-Matter Manipulation and Matter Manipulation, BFR (Can move people to different worlds such as dreams, pictures and stories), Creation, Lunar Empowerment, Dream Manipulation, Rule-Bending, Enslavement, History Manipulation, Sleep Manipulation, Presence Manipulation (Completely removed both Kosuzu's traces of existence and the aura of youma possessing her from Gensokyo), Meta-Probablity Manipulation (Created Gensokyo which is stated to be a Quantum world, a space of endless possibilities and can conversely manipulate it), Logic Manipulation (Created border of common sense as a part of Great Hakurei Barrier and that keeps Outside world's common sense away from Gensokyo, leaving what's illogical or lacked common sense inside; She should be considered to be able to manipulate it as well)

Attack Potency: High Complex Multiversal (Her ability allows her to fundamentally undermine reality which follows String Theory. In addition, she can control all boundaries, including the boundary of red and white which represents the beginning of all things. This suggests how she is stated to be comparable to those of Yaoyorozu Gods who shaped and defined the reality from a chaotic to an orderly state.) to High Hyperversal (In her her Perfect Memento in Strict Sense profile, it's shown that she she can destroy and recreate a reality like Gensokyo with ease. We know it's talking about the fabric of Gensokyo's reality and not just the land and space itself since her ability affects reality itself. Gensokyo is a brane world which is 4D to infinite-D.Gensokyo follows quantum mechanics such as wave-particle duality, which evidences the existence of infinite dimensions. Yukari is able to fully manipulate the border of this contrast between wave and particle, which is a driving force of quantum mechanics.More evidently, Schrödinger's cat is noticed in Gensokyo which proved that the wave functions are in superposition state as the experiment questions how long does superposition lasts. According to the superposition principle, wave functions can be added up to form an infinite dimensional Hilbert Space. Moreover, Gensokyo is directly stated to be a quantum world which proved Gensokyo runs fully on quantum mechanics and is infinite dimensional by necessity) to Outerversal (She governs over the boundary of physical dimensions and has powers comparable to even gods who are unbounded by any concepts as they predate the existence of any concepts)

Speed: Irrelevant

Lifting Strength: Irrelevant

Striking Strength: Hyperverse level

Durability: Hyperverse level

Stamina: Limitless

Range: Hyperversal to Hyperversal+

Standard Equipment: Her umbrella, Her shikigami Ran, her Shikigami's Shikigami Chen, crow familiars, apparently a cell phone, A Gameboy Advance, and an iPod

Intelligence: Supergenius (Being far smarter than Ran Yakumo can comprehend who is also well known to be skilled in Mathematics and can solve unfathomably complex calculations in a matter of seconds and memorizes equation of one thousand formulae. She has also outwitted the Brain of the Moon,a Genius of geniuses, Eirin Yagokoro in the pursuit of her own ambiguous goals.)

Weakness: She is considered to be quite lazy, tends to toy her opponents a lot and likely make allowances for the power of her opponent so as not to allow the battle to become too one-sided. However, in a serious situation, Yukari will not hesitate to get involved, whether that be through manipulating others or by intervening personally.
