Arcueid Brunestud a.k.a. the White Princess of the True Ancestors from Tsukihime.
Hyperversal to High Outerversal - Can fight on par with and physically overwhelm Vlov in close quarter combat,
Ancestors such as Vlov are on the level of Divine Spirits despite being severely weakened at the time.
Low Outerversal to Outerversal - As the successor of the ultimate one of the moon and one of the closest to crimson moon she holds authority over the moon cell, The Holy Grail otherwise known as the core of the Moon Cell, is a part of Arcueid Brunestud; by extension she can treat SE.RA.PH which underlies several virtual worlds of the Moon Cell as her own Reality Marble,
Casually tearing a portal through the moon cell to leave it because she has the "right" to do that; a feat that required Mythological mystic code Gilgamesh to spend 90% of his treasures in the gate of Babylon.
Translation - Berserker is the Servant you fight during the fourth round, version 2. Her master is Monji Gatou. She is a Funny Vamp [localized as Temptress] with disheveled blond hair and crimson eyes. She is a fan service character. Technically not a Servant, she is a mysterious creature that Gatou brought along from Earth. Sometimes a cat, sometimes Yuzu-nee, sometimes a silicon creature, Berserker is a princess that doesn’t seem to have a proper place in the game. She is waiting eagerly for the release of the remake. Incidentally, in the world of EXTRA where the information world (digital) takes precedence over the physical world, she is no longer the strongest. This is because in the information world legend becomes reality, and natural phenomena that have been incarnated as “Gods” can often hold more power than their original natural existence does. Well even with that being said, if Berserker regained her sanity she would easily be considered a cheat-tier Servant. Her power, “The stage is the Moon, so all targets have their power reduced to a sixth of their usual” would be extremely useful against other similar cheat-tier Servants. It’s a conceptual numerical alteration, so it is unavoidable when on the Moon. Even the Moon Cell transformed version of BB would be limited by it. As far as EXTRA and CCC go, she‘s about the only one who can bring Golden White Face [Konjiki Hakumen] down to a level where “it’s possible to defeat her no matter how slim the possibility.”
In short - In the world of extra even when weakened she's the only one capable of bringing down Amaterasu to chances where she can be defeated, superior to mythological mystic code Tamamo-no-Mae.
High Outerversal, possibly Transcendent In her battle against Ciel, she was drawing enough power to completely remake the entire planet (I fumbled with the SS but).
She's the strongest of the True Ancestors, True Ancestors are a transcendental species of vampires in the multiverse possessing power beyond human comprehension and hold energy capacities on par with celestial bodies like earth along with the status of "planet" which is a rank above the status of "God" which puts them ontologically superior to God's like Tezcatlipoca who in She greatest authority of all, such that it's an equivalent of having no limits.
High Transcendent With Marble Phantasm (The scale of Arcueid's Fantasy Manifestation, is such that it seals off the cosmos and is beyond human comprehension.
She can bring forth the Moon Castle otherwise called the Millenium Castle into existence, a canopy that covers the entire planet and is incomprehensible to human intellect.
She can achieve a feat on the level of True Magic, using the marble phantasm to bring the crimson moon from the future that Altrouge used to turn Zepia into a phenomenon that reincarnates infinitely from the Akashic Records. She disregards the contract and turns him back from phenomenon to human and removing the applications of his reincarnation to be killed.
She goes as far as to say "there's no world she cannot create" with her imagination.
High Transcendent - It is something entirely transcendent and divorced from reality, it is an "entity" entirely distinct and divorced from the concept of life and it's conventional categories; the highest order of "being" that humans are able to comprehend non other that which goes by the name God. It stands apart from the little worlds capable of being grasped by humans,
It defies human comprehension itself; something that cannot be unraveled regardless of how hard you think of it.
Translation - And now for some FAQs about the Luminary. — Can you touch it? Once it enters a stable state, the Luminary materializes—so yes, it has hit detection. It feels both like hard stone and flowing water to the touch. Also, Arc can will parts of it to rarefy, and when she does that, she can pass those through buildings and what-not. — Since it's light, does that mean it’s hot? It’s a bit hot, but not enough to get burned. — How much reason is left in Luminary Arc? Enough. She doesn’t feel like saying very much, but that doesn’t mean her reason is lost. It’s more that her True Ancestor supernaturality has gotten stronger. She does talk, but not with her voice, instead sending orders directly to the other party’s brain (telepathy), meaning that her lips don’t move when she speaks. — What does she look like to humans? Depends on the situation and how far away they are. First, when she’s emerging: it’s totally fine if she’s super scary here. I think something to the effect of the demonic terror found in the storyboard is fine. Then, when she’s stabilized—around the time when she’s caught Ciel and is playing around with her: When someone is distantly removed from the Luminary—300 meters or more outside her zone of influence—she only looks like light, while if they’re within the 300 meters of her zone of influence, she has a human shape. I think it'd be fine if one could see that there are eye-shaped holes (kind of like cavities) where her mouth, eyes, etc, are supposed to be. When even closer to the Luminary—30 meters within Arc’s zone of influence—then the light being emitted looks more subdued, with her eyes and mouth (lips) shining with the brilliance of life. In fact, make her look even more beautiful than normal Arcueid. This is like a cognitive alteration effect that the Luminary has against intelligent beings. Those who look on from afar will get the impression of something terrifyingly unknowable. While those who have arrived close will get the impression of something beautifully unknowable. Those who are far away are enemies who are to be killed without being shown the truth. While those who are close by are allies who are to be given a glimpse of the truth—a truly spiritually divine (religiously speaking) mechanism.
In short - The luminary is said to have a something akin to a cognitive alteration effect against intelligent beings, those who look from afar get the impression of something terrifyingly unknowable, while those who arrive close to it get an impression of something beautifully unknowable, those who are far away are enemies to be killed without being shown the truth. Those who are closes by are allies to be given only a glimpse of the divine truth.
High Outerversal Physically, High Transcendent Conceptually - Archetype Earth is neither the cheerful Arcueid, Arcueid before Roa caused her fall, exceeds both and exist as the highest manifestation of life on the planet.
End Results(?)-
Attack Potency: Hyperversal | High Outerversal to High Transcendent | High Transcendent (AP=Durability).
Speed: Immeasurable (it is said that she's the only one in the fate extra world, who can bring Amaterasu down to chances where she can be defeated in battle. The Amaterasu is a goddess of the sun of such great status that the time axis is irrelevant to her) | Immeasurable (Was easily overwhelming Vlov in battle, who inherited the power of one of the 27 dead apostle, who are entities comparable if not superior to servants) | Immeasurable | Immeasurable (As a person with the status of planet she far exceeds every divine spirit native to the planet, including goddesses like Amaterasu who can ignore and move beyond the time axis) | Immeasurable (Far superior to entities like foreigners/outer gods like Sut-Tyhon, who exist beyond all possible dimensions)
Lifting Strength: Immeasurable | Irrelevant (In luminary its weight would be the mass of Earth, So, no matter the action it takes, as long as it’s on the surface of Earth)
Striking Strength: Hyperversal | High Outerversal | High Outerversal | High Outerversal | High Outerversal
Durability: Hyperversal (Survived Vlov's principle) | High Outerversal | High Outerversal (survived seventh holy scripture from Ciel) | High Transcendent | High Transcendent
Stamina: Infinite
Range: Hyperversal | High Outerversal, High Transcendent with Marble Phantasm | Higher | Far Higher | Massively Higher
Intelligence: Intellectual Archetype (As an archetype, Arcueid has vast recorded knowledge about almost anything regarding earth and its textures. This includes the very beginning of the planet itself and its universes).
Power(s) and Abilities: Superhuman Characteristics, Energy Projection, Wind Manipulation. Reactive Evolution (Due to her nature of existence, she's invulnerable and resistant to magic that she's experienced; the only magic she's not resistant to is the one she has yet to experience. Upon experiencing it, she becomes resistant to that magic too). Reactive Power Level (When she restricts herself, she can consistently reactively and existentially put herself one rank above all of her opponents and anybody she fights). Plant Manipulation (She can manipulate plants like ivy and use them to attack or restrain her opponents). Organic Manipulation, Earth Manipulation, Fire Manipulation, Weather Manipulation, Lightning Manipulation, Biological Manipulation, Causality Manipulation, Space-Time Manipulation, Metaphysics Manipulation (Type 2), Logic Manipulation (Type 1 and 2), and Physics Manipulation (The entire Earth is regarded as her territory, and she can manipulate everything and create everything that derives from nature; she has authority over all of creation and can rewrite physical phenomena).
Axiom Manipulation (Has abilities of A-Reis, the latter can enforce their own truths within reality and reshape it using those truths). Adaptation (Arcueid can remake her body to adapt to various forms of magecraft; Vlov regards her body and blood as an all-powerful adaptability type that transcends anguish). Body Control and Matter Manipulation (High-class vampires can scatter the particles that make up their bodies to turn into mist or something similar). Duplication (Vampires can make clones and imbue their consciousness and magical energy to pilot them around). Telepathy (Even without luminary, Arcueid can project her thoughts and words without her mouth but rather as the voice of nature itself, projecting her words and thoughts onto the minds of others. She can read the thoughts of others as well). Information Analysis, Cosmic Awareness, and Absorption (She predominantly analyzes her opponents' strength to raise her own in accordance with the limits of her opponents' capabilities. She can also absorb information of her surroundings to gain a complete view of the world itself. When she awakens, she absorbs information about the entire texture of human order to compensate for her lack of experience with it).
Invulnerability (Magecraft is the realization of phenomena that already exist on the planet. As mages or even servants at times utilize magical foundations (basis) that already persist within the world, Arcueid, as an extension of the planet, cannot be harmed by normative magecraft phenomena as she's the basis of it. This means they have little to no effect on her outside of mystical phenomena of great rarity, like the Mystic Eyes of Death). Immortality (Type 8 and 9, as the planet's soul, Arcueid's individuality has its causes of death nullified, effectively making her impervious to death and causing her lines of death to dissipate). Power Bestowal (Both of Roa's vampiric abilities and his principle, which allows him to reincarnate, are things he stole from Arcueid).
Abstract Existence (Type 2, True Ancestors are fundamentally natural phenomena. However, unlike Divine Spirits, they are not a phenomenon affected by the Collective Unconscious. As such, they fundamentally lack even anatomy). With the Mystic Eyes of Enchantment, she gains Memory Manipulation, Fear Manipulation, Body Control, and Empathic Manipulation (The Mystic Eyes of Enchantment can induce a person to great fear, wipe out the memories of the people who observe them, and further realize sexual desires and control the body of those who observe them). Status Effect Inducement and Damage Boost (Using her Mystic Eyes, she can place several movement restrictions on her opponents and simultaneously boost her attack power).
As Red Arcueid (Same as before with): Spatial Manipulation and Gravity Manipulation (She can passively distort gravity and space by just releasing a bit of her mana or magical energy to create a barrier of defense that's impenetrable even against a multitude of Ciel's conceptual weapons). BFR and Dimensional Storage (Those taken by Arcueid's event storage never return to the material world and only exist within the shadows of Arcueid herself). Regeneration (Mid-Godly, came back from Tohno Shiki killing her with the Mystic Eyes by remaking her body). Sound Manipulation (Her claws can discharge shockwaves, which are powerful enough to kill Vampiric Tohno and, as Red Arcueid, are powerful enough to tilt the axis of the planet itself).
As Archetype Of the Moon (Same as before with): Conceptual Manipulation (Type 3; Nature 2), Axiom Manipulation, Resistance Negation, Law Manipulation, Statistics Amplification, Damage Reduction, and Statistics Reduction (Due to having authority over both Earth and Moon, everything that exists in both of those worlds is forced to follow the rules she sets. One such rule applies and embodies a necessary concept that negates resistance, reducing an opponent's power to 1/6 of its original level when on the Moon, while simultaneously increasing her power by 1/6 when she is on Earth). Wish Granting, Information Manipulation (Type 1), Curse Manipulation, Existence Erasure (Types 1 and 3), Boundary Manipulation, Life and Death Manipulation, Vector Manipulation, Chaos Manipulation, Soul Manipulation, Cosmic Awareness, Causality Manipulation, Higher Dimensional Manipulation, Void Manipulation, Possibility Manipulation, Law Manipulation, Physics Manipulation, Time Manipulation, Metaphysics Manipulation (Type 1), and Summoning (She has authority over the Moon Cell, which contains infinite possibilities existing as parallel worlds recorded from Earth. The Moon Cell encompasses several higher dimensions, such as the imaginary number space, a higher-dimensional void where distance, direction, and time change randomly and remain undefined. Anything that exists within this space is passively deprived of meaning and has its existence erased. The Moon Cell’s core is a higher-dimensional entity capable of granting any wish, even reshaping reality itself. It can rewrite the laws of physics and records or contains all information about Earth, reading and understanding the world in its entirety. Additionally, it holds the capacity to summon servants).
Luminous Body: Immortality (Type 5) and Acausality (Type 5, as the planet's soul, Arcueid is endowed with traits that make her a perfect life form through her luminary manifestation. This form is immutable, and any changes made, such as appearance adjustments, affect only the manifestation and not the consciousness or the soul of the planet itself. Because of this, she is not an "individual" or a "particularity" but rather a system, meaning she cannot be characterized as being "alive"). Conceptual Manipulation (Type 1, she can store metaphysical principles such as the lines of death in her event storage. These lines represent a fundamental concept that connects the created world to the ultimate reality, the Vortex of Origin). Mind Manipulation and Paralysis Inducement (By simply looking at someone, she can paralyze them and make them forget their humanity). Ontological Transcendent Physiology (In her luminous form, Arcueid exists as the highest order of being, transcending "life" as understood by humans. She is described as a perfect being with no limits, defying human comprehension. Tohno refers to her as far beyond the scope of "our little world," identifying her as what animals perceive as their "leader" and what humans revere as "God"). Fate Manipulation (Anything she foretells becomes an absolute truth. This is a subset of her power as an absolute being, allowing her to dictate outcomes, including the fates of Ciel and Tohno). Subjective Reality and Law Manipulation (Originally, her luminary form's only weakness was immobility, but she overcame this limitation by willing herself the capacity to move. She can only be harmed by attacks she personally recognizes as a threat). Enhanced Senses (She possesses awareness of all thoughts and feelings on the surface texture of existence. This awareness allows her to sense when anyone is out of energy, as every thought occurring on the surface texture is immediately transmitted to her).
As Archetype: Earth (All abilities previously listed and): Acausality (Type 5) and Immortality (Type 5 - She exists on the level of Ultimate Ones who lack the concept of death. When Shiki Ryougi uses her Mystic Eyes of Death Perception, she cannot see the lines of death emanating from her body, as they transcend the concept of "you"). Ice Manipulation and Wind Manipulation (She can manifest and manipulate both ice and air). Size Manipulation and Large Size (Type 11 - She can grow to a size larger than the planet itself). Power Bestowal (She has the ability to grant immortality to others). Transmutation (She can alter the forms of things and is implied to be capable of transforming people into other forms, such as dogs). Telekinesis and Weapon Control (She can wield her sword and move it using only her mental faculties, without the need for physical contact).

This should grant her resistance to the magecraft of the likes of Rin Tohsaka, Michael Roa Valdamjong, Medea, Paracelsus and many, many others).
Tier (FINALLY): High 1-A | Far higher | Higher | Atleast High 1-A | Far Higher, High 1-T with her Reality Marble | High 1-T.
Therefore, I scale Arcueid to High Transcendant (High 1-T) (PS Wiki) or Extraversal (1-S) (CSAP Wiki). I probably might've missed some things here and there, point them out.
Thanks for reading it :)
