Pre-Release WMGs
- Unfortunately Jossed.
- Also Jossed.
Ochette: Vide is connected to Night Of the Scarlet Moon (which is the cause of man and Beastling not getting along).
Agnea: Likely via the “mother is not dead” theory somehow.
Temenos: His investigation will reveal major corruption in the church via a infiltrating Vide Cult.
Hikari: The Voice is Vide.
Partitio: Roque is financially tied to a Vide cult or a crime syndicate linked to Vide.
Throne: The Blacksnakes are a crime syndicate working with a Vide cult.
Osvald: Harvey is connected to the Vide cult via evil magic.
Cassti: Eir’s Apothecaries work for Vide in some fashion and Castii was unaware. Castii’s situation being to protect her from being corrupted.
- In terms of the overall plot, this is confirmed as far as Vide being the True Final Boss goes. For their relevance in each character's story, though...
- Ochette's: Implied but not outright stated. What is more notably stated is that the Dark Hunter was part of the Moonshade Clan worshiping Vide.
- Agnea: The only story completely unrelated to Vide, so this part is jossed, although Tanzy, one of the characters in her route, has been tricked by Arcanette into locating the Sacred Flames and is sacrificed by Arcanette to put out one of the flames.
- Temenos: Confirmed on corruption with the church, but for the wrong reasons. The leader of the Sacred Guard, Kaldena, attempted to use Vide's power to take revenge for the slaughter of her people, and reclaimed the Book of Night for Vide's followers. More notably, Mindt's true identity is Arcanette, one of Vide's agents.
- Hikari: Implied in regards to Vide being the voice of Ku's curse. More notably, Kazan's true identity is Oboro, one of Vide's top agents.
- Partitio: Seemingly unrelated, until the final chapter reveals that the scrivener Ori who Partitio met multiple times was working for Vide.
- Throné: The progenitor of the Blacksnakes, the ageless Claude, was one of Vide's agents.
- Osvald: Right on the nail—Harvey made a deal with Vide's minions in an attempt to attain the One True Magic.
- Cassti: Not the entire organization, but Vide corrupted Trousseau, a member of Eir's Apothecaries, into doing his bidding, with the rest of Eir's Apothecaries sacrificing themselves to ensure Cassti survives, believing she can cure Trousseau's plague.
- And a "Harvey may not even be real" notion could in fact tie into Hikari's story and the question of just how real The Voice is and where it's even coming from, as well as some of the spiritual weirdness in Temenos's story. "Harvey" could well be an entity not unlike The Voice, and the trailers that seem to show "Harvey" deeper into the game are set up to help fake out audience expectations.
- And, of course, as a corollary: it's possible, with the above, that Osvald is physically guilty of the killings, but depending on the nature of "Harvey" and other things like The Voice, he may well have had absolutely no awareness of what he was doing; his later chapters, and part of his Crossed Path with Partitio, may involve coming to terms with what "guilt" means in such a context.
- Jossed: Harvey is confirmed to be real and is the culprit... Though he didn't immediately kill Osvald's wife and daughter, instead turning his wife into a monster and brainwashing his daughter.
- Osvald's Final Boss would be the man who murdered his family and framed him.
- Confirmed: Harvey, the man responsible, is his route's final boss.
- The trailer shows Throne being abused by a woman dubbed as Mother. This person could be her Final Boss.
- Alternatively, Mother could be the first boss of her story like Helgenish was to Primrose.
- Unlikely as the fourth trailer mentions being able to choose to fight between Mother and Father first suggesting they are the middle chapters.
- Ultimately jossed. The real final boss of her route is Claude, the progenitor of the Blacksnakes.
- Alternatively, Mother could be the first boss of her story like Helgenish was to Primrose.
- Hikari is mentioned as the younger Prince of his kingdom. Depending on how his story could go, his Final Boss may end up being his older sibling.
- Hikari and his brother may also end up dueling like Olberic and Erhardt did.
- Chapter 1 of Hikari's story in the demo makes it crystal clear that Mugen is going to be an opponent of some sort in the final game - whether he's the proper final boss of the route or a Disc-One Final Boss covering for whatever the hell the source of The Voice is is the bigger question.
- Confirmed: Hikari's final boss is his older brother Mugen.
- Temenos's final boss will be the Pontiff or the closest equivalent. His main driving factor as revealed thus far is doubt, which will likely lead to him dealing with corruption in the church that was largely ignored in Ophilia's story.
- This makes sense given Temenos is an Inquisitor.
- Jossed. The Pontiff is dead by the end of Chapter 1. Though, he is murdered by a set up and the deputy of the Sacred Guard is acting suspicious.
- The real final boss is Kaldena, captain of the Sacred Guard.
- Tying in to one of the wilder WMGs below, Agnea may well end up fighting her mother - or whatever her mother has become. Given that her plot ties into Hikari's and is thus adjacent to entities like The Voice, it's not impossible that something may be using Cuani as a Meat Puppet.
- Jossed. Her mother actually is dead, and her final boss is against Dolcinaea, her mother's student, and is completely unrelated to the overarching plot.
- Partitio's final boss may be Roque, his father's old business partner who, over the course of many years, planned both the rise and fall of his hometown via a shady contract.
- Confirmed. More specifically, it's Roque in a steam train.
- Confirmed. Harvey kidnapped and brainwashed Osvald's daughter, intending to use her as a sacrifice to attain the One True Magic, but Osvald stops him just in time. She's not fought as a boss, though.
- Confirmed to an extent. Distorted monsters that cannot be captured appear, and the final boss is the corrupted form of whatever animal companion Ochette did not choose.
- Confirmed. All of the Crossed Paths stories must be beaten to unlock the final chapter.
- Fully jossed with the demo out—the Travelers are in set places for recruitment like in the first game. The difference is that their circumstances of recruitment differ. For example, Partitio does the classic "hanging out in his starting town with a green textbox" thing, albeit he now has reactive dialogue that changes depending on who your lead character is and has different justifications for telling you what he's all about as a result, while you find Hikari in a Hinoeuman border town far from his actual "origin area", facing down a small squad of soldiers that you assist him with. He's impressed enough with you that he offers to come with you, and shares his tale as a result.
If she is alive, it seems likely she is somehow tied up in the wider, sinister goings-on that seem to tie the plot together more tightly than OT1 was—she'd have particular potential hooks into Castti's "Eir's Apothecaries disease" plot, or is tied up some way with the Hinoeuma plot and Mugen's machinations, especially since Hikari and Agnea are confirmed to be a "cross path" pair.
- Jossed: She really is gone.
- Jossed: The bloodline of Ku is tainted due to D'Arquest being a distant ancestor, Vide's influence has a grip on Hikari as it did Mugen hence why Mugen could hear the darkside of Hikari when it manifested in front of him.
