Eibon (エイボン, Eibon) is one of the Great Old Ones whose existence presides over Knowledge.[11] He was part of the Eight Shinigami Legions, and was a former friend of Death himself.[9][12] After the wake of Asura's sealing, he later secluded himself onto Lost Island in isolation, using the island's Magnetic Field as a cover.[6]

Cultural References

Eibon is based directly based from the sorcerer of the same name from Clark Ashton Smith's short story "The Door to Saturn". In the story, Eibon is a legendary sorcerer and priest of Zhothaqquah who is famous for writing the Book of Eibon, which included chronicles of his life, his magic formulae, and rites of Zhothaqquah. When an inquisition came with a writ for his arrest, he fled Cykranosh (the planet Saturn) through a magic panel given to him by Zhothaqquah, never to be seen again on Earth.


From his creation of the Demon Tools and the instructions that led to the development of Demon Weapons, as well as remarks made by numerous respected others and the confirmation provided by The Great Old One of Power, it is obvious that Eibon's most defining trait is his intelligence, which far exceeds any other individual observed thus far.[13] This abundance of knowledge is as much of a gift as it is a curse, in that while it allows Eibon to understand and see through all things, it drives those around him to madness.

Not much can be told of Eibon's actual personality in regards to the Manga. He appears to be a rather formal man, speaking with sophisticated vocabulary and not expressing much emotion at all. He does seem to be slightly concerned about Kid when he comes to Lost Island, and also seems to have an interest in helping him find the answers he seeks. Unlike The Great Old One of Power, Eibon does not present himself as an enemy of Kid or Death, and does not emit a wavelength that is relatively dangerous at close range, possibly in order to keep others from falling into madness.

However, he is not without flaws. Shinigami has mentioned that Eibon is a very curious individual. He has expressed that even when they both agreed to never try to create the Demon Weapons, as the method was unjust, he still showed signs that he really wanted to do so. This side is shown to have him align with witches. He also is one that would go to great lengths to achieve a goal, even if the consequences would cause him and his friendship with Death to suffer. In the anime, for example, he sways from Shinigami's side by aligning with Arachne in an effort to save his wife.

In the anime, Eibon presents himself with the same characteristics as what has been shown so far in the manga but inclines to a much more friendly, good alignment. He speaks to Shinigami as if the two are personal friends, and it is explained that his original goal in creating Demon Tools was to benefit and help humanity. However, it is explained that his research soon turned to a search for the way to grant someone immortality in order to save his beloved wife from death. Unable to find such a way, he was manipulated by Arachne Gorgon and created "BREW". He himself then explains his tragic grief and sorrow for straying from Shinigami's side, explaining that he has suffered the death of friendship, betrayal, and involvement with Witches. Lastly, he states the loss of the one he loved most, his wife, not to the fatal illness she had, but to the explosion set on Lost Island by Arachne. He then makes amends for these misdeeds by lending BREW's power to Shinigami, and hopes that he will save the world with it.



Eibon as depicted in the anime

Although Eibon is depicted as a relatively tall humanoid figure, due to the presence of his ornamental clothing his exact physical proportions and even his facial features remain mostly obscured, making it difficult to discern his actual characteristics. This concealing attire is comprised from a simplistic steel mask, attached to a protruding hat with an additional visor that descends down the entirety of his face, and a full length robe, which covers the remainder of his body. Layered over this dark robe are numerous linear patterned panels, accented by metallic plating that is also found on Eibon's shoulders and running down his sides, and protruding from the ends of his sleeves are similarly constructed angular projections. Completing his typical dress is a long triple-wrapped scarf, which terminates in a spherical bead and various tassels at end, and an unusual triangular section that extends forth from his chest, featuring steel panels fashioned into the shape of a capital letter "E".[14]


Being a former member of the Eight Shinigami Legions and serving as one of Death's personal guards, Eibon is known as the most powerful Sorcerer of all time.[15] His power is implied to be extremely potent and roughly comparable to the output of power from "BREW" itself, with statements from Arachne herself stating that "BREW" is Eibon.[16] As a Great Old One, his very existence drives men into Madness (specifically, the Madness of Knowledge in his case) as well as having a Madness Wavelength rivaling Asura.[17]

Not only was Eibon able to know Kid by his nickname despite not having met him but he was also able to see Kid's past experiences and even iterated his current thoughts in front of the Death God.[6] Also fitting for his status, Eibon possess the ability to see into the future, having been aware that Maka Albarn herself would be the one out of Kid's "dear friends" to learn of the location of the Kishin himself despite having not happened yet during his conversation with Death the Kid on Asura's hidden locaton.[18] In the anime, Eibon has displayed the ability to move objects without touching them. He seems to utilize this by moving his arm, surround the object being lifted in a blue aura. However, it is shown that he can also so without arm movement and can even use it to levitate himself, in which also surrounds him in a blue aura.[19]

Chapter 87 - Eibon and Kid meet again

When Kid goes back to the Magnetic Field on Lost Island, he's there to meet Kid. As Kid formulates he was, indeed, real during the battle for "BREW", Eibon is already aware of the various matters on his head: the Kishin, "BREW", and the question If his father was indeed the root cause of the Madness. He instructs on the young Death God to follow.[39] As Kid asks for information on his location, Eibon reveals he doesn't know and further states that he chooses not to know. He would also cite that what Great Old Ones are, something even that a certain "fool" understands. Although seeing him desperate, he reassures that one of his "dear friends" will present the answer.[40]

He then tells him of the Magnetic Field's properties allowing an hour to repeat to no end and assumes Kid's love for order would allow him to value such a fact. But when the boy responds with it being unproductive to the point there was no point of it happening and states the things he found unbalanced and incomplete in the Book of Eibon was the ultimate "order", he then claims that not only will he learn If Death is the root of Madness but also says he's not a fragment but a worthy Death God himself.[41]
