History Fanfic / CrackedGlass

** AdaptationalVillainy: AU All Might, as well as [[spoiler: every Demon-Universe user of One For All, as the Quirk's torchbearers hold a relatively high rank in "Demon" society as the Grandfather/Grandmother.]]

** AdaptationalHeroism: Tenko, ie AU Shigaraki, is sane, collected, mature (if slightly insecure), and [[spoiler: is being groomed as the next leader of the human resistance.]]
** AdaptationalVillainy: AU All Might, as well as [[spoiler: every Demon-Universe user of One For All, as the Quirk’s torchbearers hold a relatively high rank in "Demon" society as the Grandfather/Grandmother.]]
** AdaptationalNiceGuy: Katsuki, due to having lots of pseudo-siblings who wouldn’t put up with his shit, and eventual guilt over having been so cruel to Izuku before his "adoption," plus being expected to help care for the youngest kids.
** SparedByTheAdaptation: Inverted, played straight, and zigzagged. Some of Class 1-A don’t have counterparts who cross over as their alternates in the Demon Universe were already killed and eaten. There’s also DNA evidence that characters who don’t exist in the Hero Universe were born into the Demon Universe thanks to the TangledFamilyTree this has resulted in, and finally [[spoiler: Demon-Universe Hana Shimura is still alive, and part of the human resistance.]]

--> '''Ojiro:''' Back home, they built a giant glamorous island out of pretty much nothing where the smartest people build the most insane technology just because they can. ''Millions'' of people in one place, working to make the ''billions'' of everybody else stronger, faster and better. They can replace whole internal organs. Can ''you'' do that?

* BrokeYourArmPunchingOutCthulhu: [[spoiler: Ojiro]] gets impaled, hospitalized, and nearly killed while hitting [[spoiler: The Grandfather aka Yagi]] hard enough to put him out of commission for the rest of the fight.
* DidYouJustFlipOffCthulhu: Subverted. Shota makes a very badass BreakingSpeech against the demon [[spoiler: captured by the [=LoV=]]], but it’s his TranquilFury that intimidates those around him more than who he gives it to.

* EnemyMine: In the face of the invading demons, [[spoiler: the League of Villains]] agrees to work with Pro-Heroes in order to rescue one of their own. Later Toga and Ojiro join forces while held captive together, [[spoiler: and after the invasion is announced temporary laws are passed saying that even villains will not be persecuted or arrested if they stop to help fend off invading Nomu.]]
* ExactWords: When Ojiro has to explain to Sensei Ken how he got to be so good at fighting when Mashirao clearly isn’t, he gives some vague facts about Bakugo and lets Ken fill in the blanks. Likewise, the two of them never claim to be twins- they just let everyone else assume that.

* EvilCannotComprehendGood: The Grandfather is totally baffled that [[spoiler: a team from the Hero universe helped assault the Tiafari just to rescue one person]], and calls them naïve for doing so.

* FirstNameBasis: Justified, as [[spoiler: almost]] all the humans from the Demon universe were raised as orphans and have no last name. Eventually the initial batch of escapees are given the surname Yamada, but they still go by their first names for simplicity’s sake.

* HeroicSacrifice: Attempted at the sensei training facility during the rescue break-in. When the hero rescue team thinks they can only get a limited number of prisoners/students out, the remaining students [[MoreHeroThanThou start arguing over who should go and begin nominating one another for rescue.]]
* HopeSpot: Hooray, the rescue party found Ojiro! They have everything they need for a rescue, and the teachers are even cooperating! [[spoiler: Wait… why is the Vidame coming back?]]

** The story of what happened to Ojiro after winding up in the Demon-universe gets told in chapter 8, covering several weeks at once.

--> '''The Grandfather: ''' Your kind is going to have to learn… When to make the right sacrifices.

* ImperiledInPregnancy: A rare version where it’s the heroes doing the imperiling. [[spoiler: The Demon Queen was pregnant during the Tiafari, when Ojiro slashed her throat. It’s unclear if she survived, or if she miscarried from the attack. Granted Ojiro didn’t know that she was pregnant, but the resistance who planned to assassinate her ''did'' suspect so.]]
* InspirationalMartyr: A non-lethal example, when the students at the training facility offer to stay behind so that others can be rescued. Since there’s no glory or reward for a sacrifice like that, [[spoiler: Compress sees the students as examples of the "true heroes" Stain spoke of]] and [[HeroicRROD pushes himself well past his limits in order to save every last one of them.]]
* InvisibleStreaker: Hagakure as usual, though notably Tooru doesn’t do the same.
* {{Late Arrival Spoiler}}/[[TrailersAlwaysSpoil Summaries Always Spoil]]: The current fic description makes it clear that Ojiro plays a large role in this fic, but from chapter 1 to chapter 7 his survival was questionable, and most characters assumed he’d been KilledOffscreen.
* LesCollaborateurs: The Grandfather, all the Sensei (albeit without a choice), and by the end [[spoiler: Shota]] work with or for Demons specifically to help keep humanity imprisoned.
* LockedInARoom: Ojiro and Toga are Locked in a Closet together during the third act, as [[EatenAlive the two of them need to be "fresh" when they’re served to the Queen at the feast.]]
* MomentOfWeakness: Ojiro’s BadassBoast to Vidame Tosk is made half to intimidate the demons into leaving his dimension alone, half because he’s fed up with being helpless and getting caught up in a power trip.
* MoreHeroThanThou: When the signal-blocker for the heart implants breaks and it looks like only a limited number of students can escape from the sensei training facility, the students immediately start arguing over which of them would be able to do the most good in freedom, and begin nominating one another for rescue. [[spoiler: Compress makes it a moot point by saving them all.]]

* PromotedToParent: As there’s about fifty kids at the farm, the older kids were naturally expected to help Sensei Shota take care of the younger ones. Once they escape to UA, the teenagers become the full-on caretakers for those children and babies.
* ReasonableAuthorityFigure: Surprisingly, Ken (AU Cementoss) turns out to be one, protecting Ojiro from his superiors as much as he can when he draws the attention of Ken’s superiors.
* RescueArc: The second-to-last arc of the fic is centered around the Pro-Hero team infiltrating the Demon Universe to rescue Ojiro [[spoiler: and Toga]].
** The last arc is split between several teams, with two different rescue missions in mind: [[spoiler: Ojiro and Toga at the Tiafari, and Izuku in the Grandfather’s mansion]].

* SuperCellReception: Apparently cell phones can’t communicate past dimensional barriers, but once Ojiro and Hagakure are in the same dimension they can still send and receive texts from each other.
* SureLetsGoWithThat: During the second portal opening, the UA staff figure out that the Demon emissary believes that the Hero Universe is also ruled by Nomu, and that UA is simply an advanced farm. They play along until [[spoiler: Shota backstabs it]].

* TangledFamilyTree: Due to the complicated details of some alternate-universe counterparts to MHA characters having more children than their hero-universe counterparts did, several of the OC child-characters who escaped with alternate class 1-A are technically related to Pro-heroes in the Hero universe. [[spoiler: Ken (AU Cementoss) and Shino (AU Mandalay) having one kid each foreshadows the fact that they’ve become Sensei.]]
** Endeavor legally adopts AU Shoto [[spoiler: as well as the infant with no hero-universe counterpart who is AU-Shoto’s biological baby brother.]]
* ToServeMan: What the Demons do with humans. The plot kicks off when the alternate 1-A kids find out that their "orphanage" is actually a farm, and as soon as they’re "adopted" out they’re actually slaughtered for food.
* UnderestimatingBadassery: [[FantasticRacism Since Demons view humans as animals,]] more than once some of them jump into situations where they’re outmatched against humans, even with their amazing strength and powers.

* WhamLine: The true name of the "demons" is [[spoiler: Nomu.]]

** The dimensional portal is invented as part of Mei and co’s refusal to be killed and eaten as livestock.
** [[spoiler: The League of Villains]] overcame the scout party sent after them and then teams up with Pro-Heroes because they fought back against the scout party sent after them.
** The attack on the Tiafari succeeds [[spoiler: despite the demons knowing about the Resistance’s assassination plan]] because Toga and Ojiro refused to let themselves be eaten.
* YouSaidYouWouldLetThemGo: A variant, [[spoiler: when Shota betrays the Resistance he tells Katsuki that he was promised that the children from ''their'' farm would be spared.]]

Note that due to half the cast being alternate-universe counterparts of MHA characters, the fic uses last name/first name for different characters depending on which universe they come from. As characters from the Promised Neverland inspired world are "orphans" and [[OnlyOneName have no last names]], they are referred to by their first/only names. Characters from the main-MHA universe are referred to by their last names or hero names, depending on which is used more often in cannon.

* TangledFamilyTree: Due to the complicated details of alternate-universe counterparts to MHA characters having more or less kids, several of the OC child-characters who escaped with alternate class 1-A are technically related to Pro-heroes in the Hero universe. [[spoiler: Ken (AU Cementoss) and Shino (AU Mandalay) having one kid each foreshadows the fact that they’ve become Sensei.]]

* EvilCannotComprehendGood: The Grandfather is totally baffled that [[spoiler: Hero Society helped assault the Tiafari just to rescue one person]], and calls them naïve for doing so.

** The dimensional portal is invented as part of Mei and co’s refusal to remain and be farmed as animals.

** Also when [[LivingLieDetector Naomasa]] helps interrogate Ojiro. While Ojiro starts off trying to give ExactWords to be as misleading as possible, he leaves out details on quirk licensing to make the Hero Universe sound much more intimidating than it is.

* {{LateArrivalSpoiler}}/[[TrailersAlwaysSpoil Summaries Always Spoil]]: The current fic description makes it clear that Ojiro plays a large role in this fic, but from chapter 1 to chapter 7 his survival was questionable, and most characters assumed he’d been KilledOffscreen.

Take the popular CrossOver premise where characters of franchise A [[TrappedInAnotherWorld open a portal to the universe where franchise B live and travel through.]] Mix in an AlternateUniverseFic slash TransplantedCharacterFic with the entirety of Class 1-A transplanted into the world of {{Manga/ThePromisedNeverland]]. Add FusionFic where [[EveryoneIsASuper Quirks]] exist in the Promised Neverland Franchise. The result is ''Cracked Glass'', a story that begins with alternate-universe counterparts to Class 1-A traveling through a portal into the heart of UA in an attempt to escape the [[ToServeMan farm they were being raised in before anyone else gets eaten]].

* ImperiledInPregnancy: A rare version where it’s the heroes doing the imperiling. [[spoiler: The Demon Queen was pregnant during the Tiafari, when Ojiro slashed her throat. It’s unclear if she survived, or if she miscarried from the attack. Granted he didn’t know that, but the resistance who planned an assassination ''did'' suspect.]]

* EvilCannotComprehendGood: For a given definition of evil, the Grandfather is totally baffled that [[spoiler: Hero Society helped assault the Tiafari just to rescue one person]], and calls them naïve for doing so.

* DidYouJustFlipOffCthulhu: Subverted. Shota makes a very badass BreakingSpeech against the demon [[spoiler: captured by the LoV]], but it’s his TranquilFury that intimidates those around him more than who he gives it to.

* BrokeYourArmPunchingOutCthulhu: [[spoiler: Ojiro]] gets impaled, hospitalized, and nearly killed while hitting the Grandfather- ie demon-universe ALL MIGHT- hard enough to put him out of commission for the rest of the fight.

** AdaptationalHeroism: Tenko, ie AU Shigaraki, is sane, collected, mature (if slightly insecure), has a still-living sister who he loves, and [[spoiler: is being groomed as the next leader of the human resistance.]]

** AdaptationalVillainy: AU All Might, as well as [[spoiler: every Demon-Universe user of One For All, as the Quirk’s holders hold a relatively high rank in "Demon" society as the Grandfather/Grandmother.]]

* DoNotGoGentle: Togata is insistent on doing this, and she convinces Ojiro to do the same.
* EnemyMine: In the face of the invading demons, [[spoiler: the League of Villains]] agrees to work with Pro-Heroes in order to rescue one of their own. Later Togata and Ojiro join forces while held captive together, [[spoiler: and after the invasion is announced temporary laws are passed saying that even villains will not be persecuted or arrested if they stop to help fend off invading Nomu.]]

* GetAHoldOfYourselfMan: Togata to Ojiro, when he starts having a panic attack while they’re trapped together and going to be eaten alive at the Tiafari.

* LockedInARoom: Ojiro and Togata are Locked in a Closet together during the third act, as [[EatenAlive the two of them need to be "fresh" when they’re served to the Queen at the feast.]]

* RescueArc: The second-to-last arc of the fic is centered around the Pro-Hero team infiltrating the Demon Universe to rescue Ojiro [[spoiler: and Togata]].
** The last arc is split between several teams, with two different rescue missions in mind: [[spoiler: Ojiro and Togata at the Tiafari, and Izuku in the Grandfather’s mansion]].

** The attack on the Tiafari succeeds [[spoiler: despite the demons knowing about the Resistance’s assassination plan]] because Togata and Ojiro refused to let themselves be eaten.

* SpannerInTheWorks: Ojiro and Togata attack the Queen at the Tiafari on their own, well before the assassination team was ready.

** The attack on the Tiafari succeeds [[spoiler: despite the demons knowing about the Resistance’s plans]] because Togata and Ojiro refused to let themselves be eaten.

* LateArrivalSpoiler/TrailersAlwaysSpoil: The current fic description makes it clear that Ojiro plays a large role in this fic, but from chapter 1 to chapter 7 his survival was questionable, and most characters assumed he’d been KilledOffscreen.

** AdaptationalSurvival: Inverted, played straight, and zigzagged. Some of Class 1-A don’t have counterparts who cross over as their alternates in the Demon Universe were already killed and eaten. There’s also DNA evidence that characters who don’t exist in the Hero Universe were born into the Demon Universe thanks to the TangledFamilyTree this has resulted in, and finally [[spoiler: Demon-Universe Hana Shimura is still alive, and part of the human resistance.]]
