Beings of immense destruction caused when two Rules that are diametrically opposed to one another collide. They come in two forms: Berserk shadows versions of mythological figures, or the owner themselves going berserk, should the people that caused the error serve as the original owners of their Artifacts.
- Divide by Zero: What causes them to come into being. Two rules that are at odds with each other cause the App to break down and either cause the owner to go crazy or summon a shadow of the owner as an engine of destruction.
- Fighting a Shadow: Exceptions like Yog-Sothoth and Thor are mindless copies based on the original that can only cause widespread destruction.
- Godzilla Threshold: When an Exception breaks out, most fighters usually put aside their differences to take it down.
- Magic Kiss: One of the ways to get rid of them is for the two beings that summoned it to declare the hierarchy of their Rules and kiss, either on the lips or on their hand that has the magic symbol. The other way is just defeating the berserk Transient, which sends them back to their world.
- Attack of the 50-Foot Whatever: As seen in his image, even the tallest skyscraper in Tokyo barely compares to him.
- Casting a Shadow: Is Nether Element.
- Combat Tentacles: Like his fellow Old One World's members, he possesses grey, somewhat transparent, tentacles.
- Final Boss: Of Chapter 2.
- Horned Humanoid: Has a pair of squiggly horns on his head.
- Stripperiffic: His outfit can be best described as painted-on underwear.
- Final Boss: Of Chapter 3.
- Good Old Fisticuffs: Like Kengo, inheritor of his artifact.
- Light 'em Up: Is Aether element.
- Shock and Awe: His power as the Norse god of lightning.
- Transplant: He is a character from Fantastic Boyfriend, Lifewonders' previous game.
- Walking Shirtless Scene: Like his Exception peers, except that he is much more covered than them.
- Blade on a Stick: He wields the eponymous Lance of Longinus as his weapon.
- Cool Crown: Has a small crown on his head
- Chainmail Bikini: His limbs and shoulders are all well covered, but the same thing cannot be said for his body and groin.
- Final Boss: Of Chapter 4.
- Green Thumb: His element.
- Holy Grail: Has one, as he was the original owner of Ryota's.
- Necromancer: One of his abilities is to revive the dead as zombies, which he uses at a graveyard filled with dead angel Transients. Further ramped up in his appearance as the final boss of Aoyama Dungeon quest, where all his minions gain Guts upon being attacked, meaning that as soon as you kill them, they'll just get back up to fight you again until the Fisher King himself is defeated.
- Dual Wielding: A pair of Katanas as his weapon of choice, like Toji.
- Clothing Damage: As seen in his artwork, Yukimura's armor is torn to shreds, revealing his sculptured physique and Fundoshi.
- Fundoshi: Considering the time he is from, it's appropriate.
- Making a Splash: His element.
- Meaningful Name: Named after Sanada Yukimura.
Witch of Orlean
- Burn the Witch!: Her art depicts her being tied to an iron cross as flames surrounds her, an homage to her final fate.
- Enemy Summoner: As a result of being made from a clash between the Protagonist and Arc's Rules, she brings Thor, the Fisher King, and Yukimura along with her. Yog-Sothoth comes along too once Shiro uses his power to revive Arc. It isn't limited to Exceptions, as Oniwaka, Zabiniyya, and Ophion are brought back as well, thankfully not in their berserk states.
- Expy: Her design bears a striking resemble to another Jeanne d'Arc from another franchise.
- Jeanne d'Archétype: La Pucelle, herself. Unfortunately, her summoning art seems to imply that this represented her in her final moments before being condemned to be burned at the stake.
- Playing with Fire: Her element is Fire.
- Puzzle Boss: As a result of her being an Enemy Summoner, any attempt to banish either her or the Exceptions she summoned individually will just result in said Exception being immediately resummoned, thus needing to banish them all at once to make it stick. Luckily, with Nyarlathotep's help and Ophion, Oniwaka, and Zabaniyya being called back along with the Exceptions, it's pulled off.
- Colony Drop: Mahakala causes the moon to fall into Tokyo just by being summoned.
- Decomposite Character: Real-life wise, Mahakala is interchangeable with both Daikokuten and Shiva. Here he is his own character.
- Final Boss: Of Chapter 11, alongside Berto.
- Fusion Dance: The Exception can merge with Shiva to become the even more devastating Mahakala-Shiva, the Warmonger's ultimate weapon.
- Multi-Armed and Dangerous: Considering that he is real-life Shiva's incarnation, this is no surprise.
- Well-Intentioned Extremist: He views the game's repeating loops as endless suffering for everyone and wants to end it by destroying everything in order to end this "cycle of reincarnation".
