Exceptions are individuals who are capable of breaking the Game's loop. They are excluded from the Game early on to let the Game function as intended. They can be brought upon by two Sacred Artifacts with powers whose opposition fall outside of the System.



The contradiction between Sacred Artifacts is usually among Rules; however, generally, it can be caused by anything outside of the System involving Sacred Artifacts. Because the System can't decide which Sacred Artifact has priority, and so both Sacred Artifacts overflow with the power of their Rule. This overflow of power leads to the formation of an Exception. Since Exceptions form among two clashing artifacts, generally speaking two Exceptions are formed whenever Sacred Artifacts clashing fall outside of the System. A notable exception is clashing Sacred Artifacts with the Protagonist, who has not formed their own Exception despite bringing about the Exceptions Yog-Sothoth and the Witch of Orleans from the other clashing Sacred Artifact.

An Exception can be controlled in its power, as tested by the Berserkers. The Exception can be bound to an enclosed area set by a guild, so long as the instigators of the Exception remain within the area enclosed area as well. The Exceptions power can also be attenuated by maintaining a pre-existing hierarchy of the instigators within the guild, such as that of the Ranker system set up by the Berserkers.


Exceptions take the form of the Sacred Artifact's original owner. These Exceptions are not the actual original owners, but the product from the memories stored inside the Sacred Artifact. If the original owner is the current owner, then the current owner becomes an Exception, with the Rule flooding into their physical body.[1]13 Those flooded with such a heavy amount of their own Rule often go berserk and destroy nearby territory.

Resolving an Exception

Establishing hierarchy between the current owners of the conflicting Sacred Artifact will terminate the Exception. According to Toji, the best way to accomplish hierarchy is through physical contact on places of the body significant to summoning. This can be either through lips (where summoning is vocalized) or on one's summoning emblem.

A hierarchy may be established through a third party. For example, Shiro had formed a guild with the Protagonist and Kengo, with the Protagonist as Guild Master, enabling Kengo and the Protagonist to form a hierarchy. The Protagonist also forms a pact with the Stray Transient Oniwaka, enabling them to form a hierarchy with him as well. Through this set up, the Protagonist was able to set the hierarchy of Kengo relative to Oniwaka to terminate an exception that these two instigated.

List of Exception Contradictions

Exception Contradictions
Exception Contradiction
Yog-Sothoth Shiro's Rule of Resurrection creates bonds while the Protagonist's Rule of Rending severs them.[2]13
Thor Oniwaka's Rule of Appropriation tried to steal all of Kengo's infinite power.[1]13
Oniwaka (Exception) The result of Oniwaka's Rule becoming berserk and flooding into his body.
Fisher King Ryota attempting to use his Rule to heal Zabaniyya's flames of Purgatory which cannot be extinguished.[3]11
Zabaniyya (Exception) The result of Zabaniyya's Rule becoming berserk and flooding into his body.
Leviathan Being the incarnation of Leviathan's memories, he became an exception when he was summoned to Tokyo because the world considered him to be the same being as Typhon despite the two holding the exact opposite Role and Rule from each other.[4]
Yukimura Toji using his Rule of Eradication on Ophion's Egg after he had summoned his younger self caused a temporal paradox. Destroying the egg would make his younger self vanish, meaning his older self would never exist. However, his younger self would never have been summoned in the first place as the older self wouldn't exist at all.[5]23
Ophion (Exception) The result of Ophion's Rule becoming berserk and flooding into his body.
Witch of Orleans The Protagonist using their Rule of Rending on Arc's chains which hold a Rule of Binding.[6]15
Mahakala While Mahakala naturally exists deep under the earth beneath Tokyo, a contradiction was formed between Shiva, the Protagonist, and the 23 souls within them, triggered by their battle which fully brought Mahakala into the city. The contradiction stemmed from the opposing faiths of the worlds of Devaloka and Shangri-La. In Devaloka, Shiva would win against Varuna Kamadeva. In Shangri-La, Shiva Mahakala, that world's version of Shiva, loses despite holding the same Rule.[7]23
Ra Mu and Leviathan Ra Mu was summoned as a result of the Tangaroa∞'s Rule clashing with Protagonist. Leviathan was the result of the Protagonist's Rule clashing with Wakan Tanka∞. Through unknown means, the two became one being, with Leviathan acting as the head and Ra Mu as the body.[8]19

What if MC doesn't cause exceptions because they ARE the exceptions?!

Sure they don't have any of the traits of an exception such as being nothing but a mindless shell driven purely by destructive rage and wielding godlike powers to do so, but who cares about details like those?

I had a slightly worrying realization that the protagonist is eventually gonna meet someone who doesn't want to declare heirarchy and would need to be forced to. Would defeating the cause of the exception be enough? If so the problem is less dangerous, but feels worth considering still.

The characters that became Exceptions were done so by the "game" because the combination of their rule and role was beyond the scope of what the game could handle and could potentially break or end it. The reasons for some of them becoming exceptions are written in the 5-star "Oath" Akashic Records (ARs). Yog had the power to transcend all of time and space, Thor's power was equivalent to being limitless/unlimited, the Fisher King had a cup that could make the impossible possible, etc., so the game had to do something about them.

I remember a chapter mentioning that all the exceptions that are not contained in the Tokyo game such as Yog Sothoth and Thor and that had their artifacts were given to humans is due to their power that could possibly make the game go ad aeternum. That is truly the thing they all have in common an unlimited supply of troops that bears no true weight to them(most resurrect troops while Thor has disposable automatas).
