Brunestud of the Crimson Moon (朱い月のブリュンスタッド, Akai Tsuki no Buryunsutaddo?), also called Crimson Moon (朱い月, Akai Tsuki?), is the Ultimate One of the Moon (月のアルテミット・ワン, Tsuki no Arutemitto Wan?), otherwise known as Type-Moon (タイプ・ムーン, Taipu Mūn?).[1]



He responded to a call from the collective will of the Earth, Gaia, over four thousand years ago, and made a deal to allow for him to live on the Earth in exchange for protection against human corruption. The planet, unable to use a mirror to reflect itself, is unable to set its own standards, so only another celestial body is able to understand the death of a celestial body.[2][3] True Ancestors based in his image were created as a natural protective system for the Earth, and were set to return it to its natural state.[3] Brunestud traveled the planet, challenged random beings to defeat him, such as Gransurg Blackmore, who was nothing but an average magus, and the villagers holding Merem Solomon. He also gathered a number of followers, such as Blackmore and Trhvmn Ortenrosse, in an attempt to eventually take the Earth as his own kingdom.

In 300 AD,[4] he was defeated by Kischur Zelretch Schweinorg wielding the Second Magic. He tried to pull the moon to collide with Earth but it was pushed back by Zelretch's magic, so it was unable to affect the planet. With all of his power, Brunestud did not foresee being defeated by a human, but lost to Zelretch due to being too late in understanding the power of Magic, "a rule outside of the rules."[5]

Tsukihime worlds[]

Brunestud foresaw that his own life was reaching its end due to having too many enemies, as he has a "world corrosive will" that does not abide by either Gaia or Alaya. He desperately wished to have a vessel that abides by the standards of the world, and planned to use the True Ancestors in preparation for his extermination. They are considered to be spirits of nature accepted by Gaia, and even though they are considered the enemies of humanity, the subconsciousness of humans both accepts and denies them as keepers of nature, causing them not to be marked as targets of elimination for the Monsters of Alaya. Normally they were only created by the planet out of necessity, but Brunestud decided to teach them how to make their own kind themselves in order to speed up the creation of a proper vessel. He sought various other possibilities when an heir in the form a True Ancestor could not be born, such as the creation of Altrouge Brunestud, a being born between a Dead Apostle and a True Ancestor. While he was destroyed by Zelretch before the creation of a perfect vessel could be realized, he still has a method for revival. His Reality Marble has been left behind to spawn the True Ancestors, allowing them to inherit a "seed" on which he can imbed himself. Its purpose is so that when a True Ancestor reaches the same purity as him and body of his scale, the Reality Marble allow him to take over their bodies through spiritual possession. Michael Roa Valdamjong considers this to be an inefficient method compared to his own means of resurrection, as it is hard for a being on such a scale to be brought into existence.[5]

Altrouge and Arcueid Brunestud, who have both inherited the Brunestud name, are considered to be those closest to reaching the point of being suitable vessels.[6] Arcueid, created naturally by the True Ancestors, a method which Brunestud had given up on at the time, is considered a perfect body especially close in purity as she can summon the Millennium Castle through her Marble Phantasm ability. Altrouge still lacks the right amount of power and she is considered too unstable, though her control over Primate Murder can give her the right to be called a greater monster more powerful than Brunestud himself in a way. While the True Ancestors were his "children" based on him, only he can be considered perfect, while all of them are considered failures. This is the cause of their blood-lust, their corruption upon feasting on humans, and their connection to the moon. Each has a piece of Crimson Moon inside them and a place to accept him, which manifests in Arcueid as a type of alternate personality hiding inside of her consciousness waiting to fuse with its host. It takes the form of Arcueid's initial state before having her hair removed, and it is able to move around the Millennium Castle while she sleeps.[5] It also stays active in her unconsciousness, such as when Shiki Tohno connects to her dreams in Kagetsu Tohya.[7]

It is unable to fuse with her while she sleeps in the castle, as she is not currently in a state to accept him, and admits to Roa that, while identifying itself as Crimson Moon, it is still nothing more than an aspect of it. Every True Ancestor is an incarnation of Crimson Moon, but at the same time, they are totally different beings. The part inside Arcueid is nothing more than a shadow of her that only exists as a hologram that has possibility. It is not yet confirmed as "Crimson Moon", as it cannot become "Crimson Moon" while "Arcueid Brunestud" is still identified as "Arcueid Brunestud." It realizes it itself didn't know exactly where it stood, and states "And to think I was planning to take over." While it wishes for Roa to unbind Arcueid's chains, he speculates that as long as Arcueid is bound in her own chains, that she will eventually give up her name.[5] This personality speaks to Shiki briefly, amazed that humans are such noisy creatures, and that Arcueid can get along with such an "impolite person." It tries to insist that it is separate from Arcueid, that it is only an aspect of her that is separate from her at the same time. Shiki identifies that while it has long hair and speaks with an accent, and even as just an aspect of her, that it still is Arcueid. It is amazed by those words, as someone who would see Crimson Moon as an enemy who will take Arcueid's body is still using words that affirm its existence. Accepting the enemy means that Crimson Moon is near, to which Shiki replies that he will simply take her back by force. While "fighting with Arcueid to save Arcueid" can be considered a contradiction, he states that he will fight it, and save the Arcueid who has been bound by her own chains. It responds to him with "I hope your words will come to be more than just a simple joke" in a tone that seems like an awkward request betraying her noble self.[7]

Fate worlds[]

In Fate worlds Zelretch was not bitten by one of the Dead Apostle Ancestors and remained a human. Crimson Moon's loyal follower Gransurg Blackmore despaired at his death and allowed himself to be killed by the Holy Church.



His eyes are red, and are described as both "kind" and "scary."



He is the one who would appear before the last part.[8]

Tsukihime series[]

In the setting of the original Tsukihime series, Brunestud bit Zeltretch during their fight, transforming him into a Dead Apostle.

Fate/stay night[]

His battle with Kishua Zelretch Schweinorg is mentioned by Rin Tohsaka in the Heaven's Feel route.[9]

Melty Blood[]

The equivalent of the Crimson Moon appears in Melty Blood Actress Again as Archetype:Earth, the alternate action ideology hiding inside of Arcueid's consciousness, who takes the appearance of Arcueid's initial state before having her hair removed. She declares that she came to experience the human world for the first time. She shows a great level of power to the point that Riesbyfe Stridberg calls her "the Ultimate One" and Shiki Ryougi recognizes an overwhelming aura flowing from her and can't see her death. Ciel believes that Arcueid managed to awaken her Origin, but Archetype:Earth denies this declaring that they are intrinsically a single being, and that she simply has a very long waking period, as the basis of life for her is far too vast compared to the living organisms that live on the surface.


Brunestud is the Ultimate One of the Moon, and is thus the strongest life-form on the Moon, capable of singlehandedly wiping out all living beings on Earth.[10] The appearance, abilities and very thoughts of Archetype: Earth could be called the Crimson Moon.[11] After he vanished, individuals close to him in power and purity started being honored with the title of Brunestud.[12] But in the long history of the True Ancestors, only Arcueid and Altrouge have ever received the name Brunestud.[6] Arcueid in particular is beyond all other True Ancestors, as she can stand her ground with the first True Ancestor, Crimson Moon.[13]

All creatures known as Dead Apostles are descended from him in some way, and as with True Ancestors, he can create strong Dead Apostles by drinking the blood of a human, having created at least two members of The Twenty-seven Dead Apostle Ancestors, Merem and Zelretch, and having had both Blackmore and Ortenrosse become vampires through magical research in order to follow him. Despite the impact the Twenty-seven Ancestors have on the planet, they can be considered nothing more than a footprint that he made on the world.[5]

Crimson Moon possesses Mystic Eyes that fall under the Noble Color "Rainbow" which even exceeds the "Jewel" ranked Mystic Eyes of petrification. His ultimate mystic eyes, which blend and mix all seven colors of the rainbow like a kaleidoscope, are considered to be the mark of the King of the Moon.[14] He also holds a Reality Marble, which contains the Millennium Castle Brunestud.[6] Its purpose is to give him a new body, when a True Ancestor reaches the same purity as him and body of his scale, the Reality Marble allows him to take over their bodies through spiritual possession.[3] During his battle with Zelretch, he was able to create a mirror image of the moon and drop it towards the planet in an event known as the Moon Fall (月落とし, Tsuki Otoshi?), which forced Zelretch to use a virtually limitless Ether Cannon to push back.[15]

He can also use an ability called Alt Nagel (アルトネーゲル, Ancient Nail?), which is described as an immensely destructive pillar of wind which stretches as far as the heavens. In the world of Notes, Crimson Moon wields a Knight Arm[16] called Real of the World (リアル・オブ・ザ・ワールド(真世界), Riaru obu za Wārudo(Ma Sekai)?),[8] which is also the title of the True Ancestors's purpose of restoring the world to its natural state.[17]

    Chronology of the Clock Tower

    Circa 960 BC

    Death of Solomon the King.​
    The Age of Gods does with his death concludes.​
    The expression of Mystery — the thaumaturgical energy within the atmosphere — does with this as a threshold likewise truly come to thin; becoming as zero as of arriving upon the Occidental Calendar.​

    the Eve of AD

    Birth of the wielder of the 1st Magic.​


    00 AD

    Come of the magi that yet remained from the Age of Gods, the establishment of the foundation of the Thaumaturgical Association.​
    A movement whereby 「even that Mystery will eventually vanish, let us preserve the past in the capacity of an academic discipline」.​
    However —​

    Circa 20 AD

    Substantiation of the 5th Imaginary Aspect.​
    A new World begins.​
    It becomes a matter that Thaumaturgy and Mystery continue to persist in a different form.​
    The other magi of the Age of Gods who have occulted themselves as of the Wandering Sea and the Academy at Atlas​
    cannot endorse said movement, but maintain friendly relations of a recognition of fraternity as fellow students of Mystery.​
    This is in subsequence the Thaumaturgical Association.​

    Circa 20~100 AD

    The Director and associates are diligently active.​
    Thanks to this, students of thaumaturgy grow in number, and the liveliness of the discipline once manifest as of the Age of Gods is reclaimed.​
    From approximately this point forth, Dead Apostles manifested as of the thaumaturgical world at frequency, deeming magi as their enemies, and so assailing them.​

    Circa 300 AD

    Battle in the city as of the forests of the night; the Millennium Castle.​
    There occurred a violent clash between Crimson Moon and the Wizard Marshal Zelretch ... it is said.​

    Circa 300~500 AD

    Upon the continent, in the countries of Western Europe, the influence of the Holy Church expands.​
    The Thaumaturgical Association declines.​
    The ravages of the battle against Crimson Moon are vast.​
    The winter of thaumaturgy.​
    The thaumaturgical cities established by the Association are in the dispute against the Holy Church shut down one by one.​
    On account that Crimson Moon was annihilated, Gransurg Blackmore does in the midst of despair accept annihilation.​
    Though he reared disciples, in a battle against an Executor who chanced upon him on a night of a blue Moon, he gracefully accepted defeat.​
    「It was upon a night like this that I encountered that person.​
     That being the case, perhaps I ought to die on such a night.」​

    Circa 500 AD

    The True Ether (the 5th True Aspect) that remained as of the island of Britain vanishes.​
    A contingent of magi establish their headquarters upon the island of Britain.​
    The beginning of 『The Clock Tower』.​

    Circa 600~900 AD

    The excavation of the Spirit Tomb Albion.​
    Advancing in their excavation of Britain's subterranea, the Clock Tower acquires a vast thaumaturgical asset.​
    As of the waning thaumaturgical world, the Clock Tower becomes as a light of hope, and numerous magi and individuals of means therein gather.​

    Circa 900 AD

    Justeaze is born.​
    The Holy Maiden of the Einzberns.​
    The 3rd Magic communicated since a thousand years prior is at last substantiated.​

    Circa 1000 AD

    At the Clock Tower, the prodigy Barthomelloi makes an entrance.​
    The basis of the Lords — the magi of the aristocratic class — is established.​

    Circa 1200 AD

    The Clock Tower does in name and substance become as the center of the thaumaturgical world.​
    The institution of the system of Governorship is completed.​
    (Being that at this time, the Faculty of Policies was treated still as an academic faculty, there were twelve faculties.)​

    Circa 1400 AD

    Zepia assumes posting as the Director of the Academy at Atlas.​
    Said posting subsequently persists unto present day.​

    Circa 1600 AD

    The Faculty of Policies is in its manner of existence viewed as problematic, and its standing as an academic faculty is annulled.​
    Subsequently, it becomes as the Department of Policies, and the twelve academic faculties are amended to eleven.​

    Circa 1800 AD

    England, the Industrial Revolution.​
    Though this was as a severe blow to the thaumaturgical world, escalation in the complexity of knowledge and technology did likewise confer certain benefits.​
    Being as unto the Holy Church — which had by pushing 「a singular worldview」 expanded its influence — it constituted an unparalleled attack, the Association even provided backing.​
    Contemporaneous, the internal conflict on the matter of whether to regard the Industrial Revolution with affirmation did subsequently become as the root cause of the dispute between the Aristocratic and Democratic Factions.​
    The genre of modern thaumaturgical theory could no longer be disregarded, and was appended to fill the slot of the lost twelfth faculty.​
    However, even that it had been appended in the capacity of a twelfth faculty, being as modern magecraft was itself still held in contempt, no governor (Lord) was at this stage yet assigned.​

    Circa 1994 AD

    Lord El-Melloi dies in Japan to a trivial ritual known as the War for the Holy Grail.​

    Circa 2004 AD

    In continuity, the 5th War for the Holy Grail initiates.​
    It is rumored that the 3rd Magic is reenacted.​

    2015 AD

    As of an Adjacent World, a Grand Order is issued.​

    Brunestud [Term]
    Despite being Arcueid's last name, strictly speaking it is actually more like a title. It is possessed by all of the members of True Ancestor royalty.
    The Millennium Castle Brunestud where Arcueid had sealed herself away is not her original creation, but was actually created in the past by the most powerful True Ancestor, using marble phantasm. That original lord of Castle Brunestud died long ago, but ever since those True Ancestors capable of forming the castle have been uplifted as royalty. This is why the True Ancestors, who have no concept of hierarchy, nevertheless call Arcueid their princess.
    After being tricked by Roa and killing most of the True Ancestors, Arcueid crucified herself on the throne of the castle she materialized herself. A thousand chains stretched from the castle's outer walls to the throne, so that she may seal herself away forever.
    In Melty Blood, the Tatari Arcueid materialized the Millennium Castle. Later, in Re-act, it also appeared in her Arc Drive.
    Currently, there are only two bloodsuckers with the name of Brunestud: Arcueid and Altrouge.

    Please tell us about the origin of the circle's name(^^)

    Nasu: It was quite difficult to decide. Someone had said "Isn't Aristoteles good enough?" but I didn't like that personally. This is about the Aristoteles from Note. but that naming for me was a case of youthful indiscretion. Then, since we were going for something related to Note. anyway: "...Actually, about that story, just before the last part Type-Moon's identity will be revealed. Also, the Knight Arm it has is called Real of the World(True World)."

    I revealed this material I had been keeping secret, then we decided that in this case Type-Moon would be good.

    誰かが、アリストテレスでいいんじゃないの? とこぼし、個人的にそれはイヤだったんです。

  10. [v] Notes - Aristoteles [Ultimate ONE]

    Aristoteles [Ultimate ONE]
    Life forms that came from the other planets.
    They were the strongest life forms on their respective planets, and each of them had the power to wipe out all the remaining living beings in this world.
    The name Aristoteles was given by the humans, and they have no such things in the first place. The Aristoteles don't fight each other, and they just freely fly around killing things.
    Several Aristoteles among them contacted mankind learning about this planet's concept of "knowledge".
    After Type-Saturn, who received orders from their respective planets and sent it to the others, got eliminated, they entered a final war with the human race.

    Shall We Play Around Some? [Technique name]
    Arcueid's Last Arc.
    For just a second, it is possible to catch a glimpse of the vampire princess Arcueid's true power. The phantom that appears behind her back is her original form. Its appearance, abilities, and very thoughts could be called the Crimson Moon.
    The inspiration for this technique comes from Kagetsu Tohya. Specifically, the episode where Shiki strayed off into Arcueid's dream and received proper retribution for killing her. Because of that, when this technique is used on Shiki it hits eighteen times.


  12. [v] Melty Blood Act Cadenza PS2 Manual - Dictionary: Crimson Moon [Term], p.060

    Crimson Moon [Term]
    Another name for the organism that was used as the template for the True Ancestors. Also known as the Crimson Moon Brunestud.
    After he vanished, individuals close to him in power started being honored with the title of Brunestud.
    However, in the long history of the True Ancestors, only two have ever received the name.

    Noble Colour [Others]
    A name for inborn special talents, used within the Association.
    Primarily used in reference to those who possess mystic eyes. For instance, the mystic eyes of Tsukihime's Shiki are an example of a Noble Color.
    Rider's mystic eyes of petrification fall under the classification of "Jewel", which exceeds even the "Gold" possessed by the highest class of bloodsucker.
    Further, beyond Jewel lies "Rainbow". These ultimate mystic eyes, which blend and mix all seven colors of the rainbow like a kaleidoscope, are considered to be the mark of the King of the Moon.

    Q: You must tell us the details of the battle between the Crimson Moon and Zelretch at his prime!!

    A: You are asking me to divulge such delicious details from my stash of ideas? Mmmm... I have shown some similar scenes in Mahoyo, they would carry a similar vibe. It would be something like, the Crimson Moon dropping a mirror image of the Moon (HERE IT COMES!) versus Zelretch doing something only he was able to do: a virtually limitless Ether Cannon unleashed through a special magic circle ("Magic Square"). If we had five times the budget of Mahoyo, then we may be able to realize such a scene.



  16. [v] Notes - Demonic Sword [knight arms]

    Demonic Sword [knight arms]
    The name of the weapon that Knights carry.
    All human species born in this world are effected by Gin. Babies born with a large amount of Gin in them shape it as if it's their bones during their lives, and when they reach adulthood, it is laid outside their body. Because it is created with the unanalyzed entity Gin, it is able to cause various effects and its power is strong enough to be considered a weapon.
    Only few humans can shape the Demonic Swords, and those who carry a Demonic Sword powerful enough to be used for war are considered as Knights. Only one Demonic Sword exists per Knight.

    But before that, what made it create a sensor like the True Ancestors?
     The reason why they are affected by the moon.
     The reason why they, who should be perfect, are not.


     It is their purpose to return the planet to what it was in the past.
