All seven Lostbelts have been excised, yet the Earth remains bleached. Chaldea is heading back to their home base in the South Pole to investigate Daybit's claims that the Foreign World CHALDEAS is the true cause of the Human Order Revision when they come across a massive barrier covering Antarctica. Due to Chaldea making constant use of things not of the Human Order such as the Servant Extra Classes, they are barred from approaching CHALDEAS which has become the Foundation of the Human Order after the destruction of the Lostbelts. Chaldea must once again travel the bleached Earth and clear their debt to the Human Order in the Ordeal Call before they can confront the mastermind in Antarctica.

- All There in the Manual: Nasu discussed in an interview why, despite there being four Extra Classes that need working out, the other four were left untouched:
- Moon Cancer is less of an official Class and more like, in Nasu's words, some kind of "postgame EX recruit" or "gag character" designation. In-universe, the Class is treated as having what is essentially diplomatic immunity, since the Moon is Earth's closest neighbor; so long as they don't make trouble for the world, the Ordeal Call won't make trouble for them.
- Pretender has no conflicts because its members take on the identity of pre-existing Servants within the seven Main Classes, so the Human Order recognizes them as such.
- Beasts flat out ignore the rules that the World has set just by existing. Short of hurling the Counter Force at them at full force, the Human Order can't do anything about them.
- Shielder is the one oddity in the list because it is coming under fire by the Human Order, but Nasu deemed a dedicated chapter for a Class represented by one person (Galahad, whose power is wielded by Mash) to be wasteful. Instead, Mash will be given a unique story arc within the other Ordeal Call chapters on the table.
- Breather Episode: There are no fights or even multiple sections in this chapter, just a single node to calm down from the madness of the last Lostbelt and finally assess the growing number of mysteries that've been piling up at Chaldea's feet.
- Company Cross References: Goredolf mentions that there's an old family who practices Substitution Magecraft separate from the Clock Tower, a reference to the Ainsworths from Fate/kaleid liner PRISMA☆ILLYA.
- Didn't See That Coming: A wall of pure Human Order preventing the defenders of the Human Order from solving the problem was not something anyone expected. Even "Romani Archaman" is so baffled by this turn of events that he actually tells Chaldea how to fix it.
- Eldritch Location: While there was something clearly up with the Traum Singularity, this chapter reveals how weird it really was. A Singularity is usually a segment of the real world cut up into its own little pocket dimension, but in Traum nothing except the Area 51 Subject E room was real. It was all an entirely made up fantasy land based on a room that lies in another plane of existence.
- Foreshadowing:
- When "Romani" explains the details of the Ordeal Call, he initially says there will be four trials, but pulls a Verbal Backspace and instead says there will be three, setting up the potential for a fourth trial.
- Curiously, the problem with the Human Order barrier is stated to be abuse of the Avenger, Ruler, and Alter Ego Extra Classes — despite Chaldea also using a certain other Extra Class far more divorced from the Human Order. Sure enough, with the PV trailer's upload, part of the Foreigner Class Card shows up in a Freeze-Frame Bonus.
- Gameplay and Story Integration: Even discounting Events and Main Interludes that occurred in Part 2, the protagonists have had to interact and work alongside Extra Class Servants in the main story, including Qin Shi Huang Di (Ruler), Ganesha (Moon Cancer), and Kingprotea (Alter Ego) to name a few. And that doesn't even cover antagonists of this subset like Ashiya Douman (Alter Ego) and Oberon Vortigern (Pretender), or pre-Lostbelt Servants like Sherlock Holmes (Ruler) and Edmond Dantès (Avenger) who have been with Chaldea since Part 1. And that's without even getting started on the Foreigner Class, which didn't even exist before Chaldea's circumstances and involves beings strictly outside of the World's purview, several of which are Threats to Humanity by themselves.
- Infodump: The entire chapter is a 20 minute long exposition session explaining many of the mysteries encountered throughout the entire game, particularly about Subject E and the Traum Singularity.
- Irony: Waver stressed in Lord El-Melloi II Case Files that trying to solve whodunnit in the world of Magecraft through howdunnit is impossible since there are near infinite ways to accomplish the same thing with Magecraft, so it's better to go through the whydunnit route first to uncover the other two. In the mystery of the Human Order Revision, the exact opposite happens; the whodunnit (Marisbury and CHALDEAS) is answered by Daybit leading to the howdunnit (Substitution Magecraft) being solved this chapter, but the whydunnit (the end goal of Grand Order Animusphere) is still a big blank.
- No Man Should Have This Power: As the Extra classes of Ruler, Alter-Ego, Avenger, Foreigner, Pretender and Moon Cancer are all not normally part of the summoning system, the Human Order itself has deemed them as a potential threat to the stability of humanity, and because Chaldea (and by extension, the player) have been repeatedly using them over the course of the story, it's led the world to view them as essentially foreign outlaws. Meuniere even compares it to abusing weapons that have been outlawed by international humanitarian law. The solution to overcoming the barrier protecting Antarctica, then, is to prove that mankind should have this power by proving it can be of use to humanity.
- The Reveal:
- The bleaching of the Earth was indeed carried out by CHALDEAS. This was done by bleaching the surface of CHALDEAS itself and using basic Substitution Magecraft to swap the surfaces of the Earth and CHALDEAS since the latter is a replica of the former. This means fixing the Earth is as simple as performing another swap, and all of Chaldea is elated at seeing a light at the end of the tunnel.
- The Trees could only be planted on a bleached surface empty of humanity, which means that the humans inside CHALDEAS were wiped out in preparation for Marisbury's plans. The last human alive there somehow found out about this and swore vengeance against Earth, creating the Traum Singularity as a means to do so.
- The human Subject E is the last human who died just a few days before being found. By virtue of being the only human left they became the representative of all humanity inside CHALDEAS as well as the last Master, giving them the ability to summon hundreds of Servants by themselves.
- The Subject E room in Area 51 takes place inside CHALDEAS, and is the only place not to be swapped. The cosmic corridor seen in Traum is because Chaldea was transitioning from Earth to CHALDEAS. This is implicitly the reason for the Ominous Visual Glitch seen when Rayshifting to Traum. This also gives the Foreign Priestess a reason for destroying the room in the Nahui Mictlān prologue, as it deprives Chaldea of a backdoor into CHALDEAS.
- The Reconstruction of Humanity was meant to take place at the end of 2016, but was postponed because of the Incineration. When Lev threw Olga Marie into CHALDEAS, he also threw a proverbial wrench into Marisbury's plans by allowing Goetia's own plan to get off the ground; both Goetia and U-Olga Marie were entirely unforeseen complications, and the dust has yet to settle for either.
- "Romani Archaman" reveals that Chaldea's summoning of Extra Class Servants (primarily Rulers, Alter Egos, and Avengers), has resulted in them being seen as "foreign" to the world in a No Man Should Have This Power sort of way, similar to how Scáthach was booted out of humanity. The only way to fix it is to find a way to seemingly prove how these Extra Classes actually serve the Human Order so they can be recognized as naturally belonging to the planet. The preview hints that this is the basis for the next three story chapters.
