Chiaki is in a coma and her physical body is still in the real world
This theory is based on the 1992 show The Odyssey.While Chiaki is wondering in the fantasy world at the moment. Her friends and doctors are trying to bring about her recovery. Chiaki will eventually waken but will still be between two worlds. This leads to another theory based on American McGee's Alice. Where she would find the two worlds merging in her mind.
The flaw in the latter is that Chiaki may become insane and be committed to a mental institution which can't exactly happen given how she will eventually become a highly respected Manga artist as seen in Rain.
Alternatively, Chiaki isn't in a coma, but is experiencing some kind of astral projection like in John Carter of Mars or Insidious.
Anytime Chiaki loses consciousness(including going to sleep) in the real world, she enters the other world and vice versa.
The comic will bounce back and forth between the two worlds, with time only passing in the other world while she is asleep, making it kinda seem like a dream-world to her.- Jossed, Chiaki appears to wake up in her homeworld near the end of Chapter 1, but that's just a dream, as she wakes up and is still very much in the other world.
Kaminari and her adventure was a part of the Other World's history.
Same goes with Birth of the Lilim, and if so, something tells me that both manga-presented segments of history had an effect on the events of MIS and STP.- Confirmed with mentions of the Age of Lilim and Princess Kaminari. (The events are even given specific spots in the Other World timeline, with BotL taking place >3000 years before MIS and BWK taking place 16 years prior.)
Something terrible happened to Toria and the skyfolk survived
Kaminari and the Kingdom of Toria are revealed to be real after all. Seeing that Eiji shows a cousin-like relationship to Nagisa... Something really trumatic must have happened that made them change their ideas.Either the skyfolk chose to come to the surface or they had to.
Nagisa actually is the princess
She’s pretending to be the other child to hide. Maybe the other child died from the fall and she’s traumatized by guilt.- Jossed from the get-go. Even before we knew of Kaminari and Nagisa, Rain's loredump told us that the "other child" survived the fall alongside Kaminari and was raised by a human family, matching with what we know about Nagisa, and Kaminari and Nagisa appear as protagonists of separate Koizumi mangas, proving they're not one and the same.
Chiaki will end up coining the phrase "demisexual".
- Watsonian perspective: Given Chiaki's circumstances (and MIS's author), Chiaki's likely finding out she's demi before getting back home. She'd likely end up coining the phrase for convenience's sake.
- Doylist perspective: "Demisexual" wouldn't be coined until 2006, whilst *MIS* is set in mid-2000. Having Chiaki come up with the phrase herself would be a convenient workaround for that minor anachronism.
- Additionally. She coins it after learning the term “demi-human” from the other world.
Further elaboration on "Corruption"
Name carving grants the corrupting demon mind control (or even just body control) over the victim. Which explains how Belial would be trusted to guard an obviously sensitive area. The GA Library probably allows demons whose corruptors have been killed, and who have otherwise been appropriately vetted, into their ranks. Theo is a closeted trans girl
His parents are very controlling and kept him unsealed. By extension, they also forced him to repress. Chiaki's alignment will be:
- Spirit, due to Chiaki being Unbound and all.
- Fire-aligned, which could help Chiaki and Nagisa bond even further and maybe even cause Nagisa to unseal hers after watching Chiaki use it.
- Light, because Chiaki needs a way to charge the battery of her UsaMaMa-chan.
- Something new, or a multi-alignment; it's a more exotic answer, but she is Unbound, so maybe certain rules don't apply to her?
- Additionally, maybe there's another alignment that she has that is undiscovered or maybe once considered extinct, having not appeared for many generations?
- Going this way, maybe she has an "Observer" alignment, giving her magic around enhancing senses - possibly telepathy. It could explain why she could hear Fumiko for a period; she was hearing her thoughts across the divide, her body being there while tapping into the magic here. Particularly strange, perhaps, but also she was stressed and didn't have control of her powers, whatever they may be.
- Chiaki has no alignment, as alignments only apply to those born under the stars of the "Other World".
- All of these have been jossed. Chiaki's alignment is Wind.
The kids who stole Eiji's pizza will turn out to be Justified Criminals with a Heart of Gold.
The viewers were initially led to believe that Jude would be a Dragon Hall member, but this seems to be anything but the case, since he and his companions (Arc, Rhys, Bonnie, and Harley) simply refer to their victims as "library kids" and appear not to know the distinction between Golem Hall and Dragon Hall. It may thus be that they thought they were stealing from Dragon Hall and celebrated the theft because they thought they were sticking it to the man. (Whether they will change their tune when they learn that Eiji was from the less rich Golem Hall or resent Golem Hall for being more privileged remains to be seen, but this Troper and many other fans believe they will be anti-villains who eventually become supporting characters regardless.) One fan even remarked that Jude's design seemed to mark them as a potential supporting protagonist. This theory would also explain why Arc, a literal child who otherwise has no business being part of a gang of bandits, is following them (Word of God confirmed that she is 10-11 years old). She could have been a street urchin they adopted out of sympathy (as they likely come from similar backgrounds), and/or she could have a sibling-like relationship with one of the other thieves.- With how many teasers regarding the thieves Lynn gave prior to Chapter 4 and the fact that Chapter 4 started with and seems to be focusing on them, this theory looks like it's getting stronger.
- Confirmed.
Theories about the thieves' backstories
- Arc: An orphaned street merchant who was found and taken in by Harley.
- Rhys: A servant of Bonnie's family who Bonnie had fallen in love with against the wishes of her family (who'd bethrothed her to Theo). He was also mistreated by Bonnie's family and grew weary of them.
- Jossed; while how he met Bonnie remains unclear, he is an Unbound.
- Harley: A street urchin who was sought out by and offered to join the thieves (especially considering he was the only one who knew sign language) but refused to accept unless they let Arc in too.
- Jude: Jude attempted to examine the cursed choker that he now wears, but it automatically latched onto his neck as soon as he touched it.
- Bonnie: A princess of the Rose Kingdom who survived the demise of her family due to being sent to study at the GAL, she eventually found herself at the mercy of scheming nobles. Four years prior to the main story, one of those schemes (probably engineered by Theo's father) resulted in Bonnie being forced out of the upper echelons of society, eventually causing her to join the bandits.
- Jossed; she ran away from her apparently abusive royal family together with Rhys, bringing her into a life of banditry.
When they were younger, Keegan and his sister were attacked by a rogue Unbound.
Keegan puts on the act of a goofy, energetic prankster, but the few times we've seen him without that facade, it's made abundantly clear he's working through some trauma. When talking to Belial in Chapter 2, he reveals he wishes to become a demon because he wishes he could protect his older sister, whom he greatly respects and who was horribly injured while protecting him. One chapter later, when Chiaki reveals she's an Unbound, Keegan doesn't respond and later distances himself from the rest of the kids due to a fear of Unbounds. Following this logic, a young Keegan must have been attacked by a rogue Unbound. During this attack, his sister successfully rescued him, though she sustained some terrible injuries in the process. (Bonus points if the person who attacked Keegan was a Corrupted Character Copy of the typical generic isekai hero.) The ending
When the comic eventually ends, we'll catch up with Chiaki about twenty years later, making an appearance at a convention in the hometown of the English VA of the title character (or close enough) of the anime adaptation of one of her works, and a certain superfan of hers will finally get to meet her.- Extra cute points available if Koizumi still uses an UsaMaMa-chan as a fidget and Lydia recognizes Momokomo.
