Eibon (エイボン, Eibon) is an enigmatic sorcerer and former acquaintance, if not friend of Shinigami, who is revered for the creation of numerous Demon Tools, including Brew. As one of the eight Great Old Ones (旧支配者, Gurēto Ōrudo Wan), his "wisdom" (知恵, chie) and very existence drives men to madness.


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 Black Mass, it is obvious that Eibon's most defining trait is his intelligence, which far exceeds any other individual observed thus far.[1] 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 Black Mass, Eibon does not present himself as an enemy of Kid's or Shinigami's, 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 mention 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. Like for example, swaying 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's 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 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. And lastly, 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
DantmanAdded by Dantman

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 entirely obscured, making it impossible 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".[2]


During the Grim Times, Eibon served directly under Shinigami as one of his Eight Powerful Warriors alongside the other Great Old Ones, where he partook in various confrontations as part of a long lasting battle against the Witches. However, sometime after the events surrounding the devolution of Asura into the first Kishin, he disappeared from the world, leaving many questions surrounding the conditions of his existence.

In the Anime, It is also explained during the time he was with Shinigami, he sided alongside the witch, Arachne, in an effort to save his love one. Their partnership would result in the creation of BREW. However, she would perish after the island explosion.[3]


Demon Tools: These objects are magical artifacts that are capable of achieving specific individual feats that are regarded as being impossible to accomplish by scientific means alone. It is thanks solely to Eibon's expansive knowledge that such items were able to come into existence and even now, nearly 800 years after his disappearance, their continued creation is only made possible due to the various blueprints Eibon left behind within the confines of his collected works, The Book of Eibon. The known tools that are directly accredited with Eibon include:

Moral Manipulation Machine (道徳操作機, Doutoku Sousa Ki): As its name implies, this artifact is capable of manipulating a subject's morality through magical means. By altering the strength of an individual’s morality, they can be made to become more evil or good, dependent upon whether the value is lowered or raised.
Eternal Spring (永久弾機, Eikyuu Zenmai): This artifact can be inserted within a machine to provide an infinite and alternative source of power, allowing the machine to run for eternity without the need for fuel or maintenance. The tool consists of two parts, an ornate key and red box in which it turns, both of which were once installed within a train behind a plate inscribed with both Shinigami and Eibon's names.
Brew: Said to be his most powerful creation, it is believed that together with the Book of Eibon, the pair form the wisdom of Eibon, which is essentially Eibon himself. The tool possesses numerous wondrous abilities, such as massively expanding the soul wavelength of its wielder, but many of these still remain a mystery to all but Eibon himself.

Madness (発狂, Hakkyō): As a Great Old One, Eibon is a tremendously powerful entity that presides over one of the pursuits that drives men towards madness, which in his particular case is the quest for "Wisdom" (知恵, Chie).

Genius-Level Intellect: Eibon is, perhaps, the most intelligent individual in Soul Eater. He's has been seen highly knowledgeable in various fields on Science, Soul Studies, and Magic. So much so his Demon Tools are considered very dangerous.

Part in the Story

A Eve's Fight to the Death

Eibon made a cameo along with the The Index from the Book of Eibon in a flash about Asura.

'Brew' Tempest

Eibon's Interruption
Eibon's abrupt presence interrupts the conflict
Blackstar1Added by Blackstar1

Engulfed by the swirling magnetic field located at the center of the Lost Island, which has resulted in an unusual temporal anomaly that manifests itself in a repeating holographic representation of the events occurring in the area over 800 years ago; Maka Albarn, Black☆Star, Death the Kid and their respective weapon partners encounter Mosquito, just after he had obtained their mutual objective of capturing the Demon Tool, "Brew". As the two opposing forces ready themselves for the inevitable confrontation, their preparations are abruptly interrupted by the sudden presence of a strange individual crossing the battlefield, whom Kid identifies as Eibon.[4] Due to this solitary apparition seemingly being entirely oblivious to the current situation, it is assumed that this Eibon is but an image resulting from the effects of the devastating explosion, indicating his presence on the island just over 800 years prior.[5]

Just a Simple Murder Story

Ascertaining from the remarks of the Black Mass that Eibon is in fact still alive, Kid concludes that the suspected image he observed while on the Lost Island was likely the real Eibon, simply utilizing the unusual phenomenon to conceal his actual location from others. Returning to the interior of the magical magnetic field, Kid challenges the supposed apparition and Eibon admits that he is indeed correct. Aware of Kid's hidden misgivings about Kishin, Brew and whether his own father is the root of Madness; Eibon asks the child to follow him.[6]

The Hunt

Eibon guided Kid about what to do and tells about the Kishin that only one of his friends can have the answer.

In The Anime

When the anime diverges from the manga after the conclusion of the battle for Brew, it is revealed how Eibon came to be the authority on the development of demon tools and that the research had originally been designed for preserving order in the world. At a certain point though, Eibon’s research began to become more focused upon the subject of immortality. It is then later explained by Excalibur that the reason for this was in order to save his sick wife, but he couldn’t make any progress and eventually turned to Arachne for assistance. The end product of the two’s combined research was the Demon Tool, Brew.


The five remaining Eight Powerful Warriors

  • Just as within the Soul Eater series; Smith's Eibon is accredited as the writer of the Book of Eibon, a tome that, among other things, chronicles Eibon's life and includes his magical formula.
  • The Black Mass describes the qualities of the five remaining warriors as "Order, Wisdom, Power, Anger, Fear". It is presumed that Eibon's respective property is "Wisdom".
