History Fanfic / BlessedWithAHerosHeart

* AtomicFBomb: Izuku's reaction when [[spoiler:he learns that the Sage Claire was looking for is actually him]].

*** [[spoiler:He heals Princess Iris Belzerg of heavy metal poisoning, by using his knowledge of modern medicine to extract the gold in her organism]].

* BeyondTheImpossible: Izuku uses his Earth-based knowledge and his ability to pick anything apart to do things that would normally take much more powerful people to carry out - such as helping Megumin cast Big Bang (an UpToEleven version of Explosion) or creating his own tree (which is apparently a Druid's equivalent of finding the Holy Grail). [[AchievementsInIgnorance And all of this without using a focus]]. Because of this, everyone's convinced that Izuku has to be an Arch Druid - well before he achieves that upgrade. He then goes and [[spoiler:reincarnates not only Keel and Sasha, but all of Keel's captains, giving them a second chance to live - when the mere act of reincarnating just Keel would have been out of reach for most people that could use that spell. Granted, he does this by sacrificing most of Keel's treasure to make up for the cost, but [[TheArchmage Yunyun]] is completely overwhelmed by the feat.]]

* DoingInTheWizard: The "respawning coffers" in Keel's dungeon that were refilled every year? Those are actually perfectly normal chests that Keel had his minions refill every now and then, to see if they could attract a priest powerful enough to purify him.

** Later, Megumin bonks Izuku on the head after he offers to reincarnate Wiz, after he had just done the same for Keel and his people without sufficient time to rest.

* NayTheist: Izuku knows that gods exist, but if they regard their {{Corrupt Church}}es dealings as good, then why would he want to worship them?

*** When he taught nuclear physics to Megumin, she used it to create [[FantasticNuke Big Bang]], a spell powerful enough to turn a castle and the cliff it stands on into a crater.

* ScrewTheMoneyIHaveRules: [[spoiler:Izuku has no problem with using the huge fortune Keel has accumulated to reincarnate him, his beloved and all of his people, and rejects any reward beyond a token of friendship from Keel.]]

* ScrewThisImOuttaHere: [[spoiler:The Thief in Kyouya's party decides to hightail her way back to Axel and leave Kyouya after she learns of Izuku's and his party's feats, as well as realizing that Kyouya's obsession with Aqua is going to doom the party.]]

* SlaveryIsASpecialKindOfEvil: When Izuku hears about the widespread slavery in the world, he is outright furious about it. He brings in two slaves into his service with the oath that he will find a way to erase their slavery marks while treating them like family. However, when Kyouya Mitsurugi finds out, he immediately considers Izuku evil without even paying attention to what Izuku actually does - and fails to learn that Izuku was about to use Aqua's debt to him to free the girls.

* StatingTheSimpleSolution: The Adventurers' Guild is trying to convince Izuku to stay in Axel and they resort to convoluted schemes to find something to tie the Arch Druid to the town. As far as Liza is concerned (even if she never says it), they could have just asked Izuku.

* SoreLoser: Kyouya claims Izuku cheated in their magic duel, when everyone else agrees that Izuku won fair and square. The fact that he attempts to attack Izuku ''after'' the duel ends only make it more obvious.

* AwesomeButImpractical: Reincarnation is this. It does bring people back from death, but it requires much more mana than Resurrection (a quantity that increases the longer someone has been dead) and has a high chance of bringing people as a different race or gender. The only advantage it has is that it purifies the soul of sin and curses.

* BeyondTheImpossible: Izuku uses his Earth-based knowledge and his ability to pick anything apart to do things that would normally take much more powerful people to carry out - such as helping Megumin cast Big Bang (an UpToEleven version of Explosion) or creating his own tree (which is apparently a Druid's equivalent of finding the Holy Grail). [[AchievementsInIgnorance And all of this without using a focus]]. Because of this, everyone's convinced that Izuku has to be an Arch Druid - well before he achieves that upgrade.
** He then goes and [[spoiler:reincarnates not only Keel and Sasha, but all of Keel's captains, giving them a second chance to live - when the mere act of reincarnating just Keel would have been out of reach for most people that could use that spell. Granted, he does this by sacrificing most of Keel's treasure to make up for the cost, but [[TheArchmage Yunyun]] is completely overwhelmed by the feat.]]

** Her church seems to be little better. After they demand Izuku to be punished (or even executed) for [[spoiler:reincarnating Keel and his people, thus]] depriving them of their main income source, and then attempt to extort him by threatening not to provide any healing services for him, when their temple is to be foreclosed (after their head priest went on the run with the money Izuku had given them to pay their taxes), they have the gall to ask for more money.
* EveryoneHasStandards: Chris, like most followers of Eris ([[spoiler:i.e. herself]]), hates harpies, but she is taken aback by how some of the Church of Eris extended that hatred to all demi-humans, even the ones Eris likes.

* ForWantOfANail: The story begins when All Might accidentally kills Izuku while trying to blast the Sludge Villain when it captures Bakugo.

* GivingRadioToTheRomans: Downplayed. Izuku sells his solar calculator to Luna and teaches sciences to Megumin, but apart from that he does not appear to show people much about his Earth knowledge.

* HiddenDepths: Chika is intelligent enough to become a mage, while Liza has greater wisdom than most adventurers.

* HoistByHisOwnPetard: Aqua forces Izuku to pick "the most powerful thing in the room" so she can get rid of him as fast as possible - after Izuku pointed out that, technically, ''she'' is "the most powerful thing in the room". Aqua's bosses use ExactWords to force Aqua to go with Izuku in his quest.

* MundaneUtility: One of Izuku's main uses for his powers is... making berries for him to eat. They are special berries that feed you the equivalent of a day's dinner and heal you, but, still, berries. He then discovers they can be used for both making good quality wine and cheap healing potions.

* UnderestimatingBadassery: Kyouya challenges Izuku to a magic duel in order to force him to free Aqua of her debt, thinking it will be easy because he has a CoolSword and lots of experience, while Izuku is only a low-level Druid. Izuku defeats him before Kyouya can even ''try'' to attack him.

* UngratefulBastard: Aqua. She thinks herself entitled to constant worship and adulation, but she is unwilling to do anything to merit such, even though she knows it is on her best interest to help as much as possible. Every time Izuku helps her, she complains and demands to be freed from the debts she incurs from this. Needless to say, Izuku is not too heartbroken when she leaves, although he does still tell her she can return whenever she wants.
** Kyouya. Aela offers to temporarily take on his fifty million eris debt to Izuku (which he only got because he decided to duel him even though he was warned not to), and he claims he will soon return to make the payment. Instead, he leaves Axel without warning Aela, nor leaving anything behind to help her live. The only reason Aela keeps going is because Izuku takes her in his party.

* WithFriendsLikeThese: Aqua is really unhelpful when it comes down to help Izuku, even though it is in her best interest to do so. Fortunately, the other allies Izuku later picks up are more up to the task.
** She somehow becomes worse when she ditches Izuku and joins Kyouya, taking advantage of his worship of her to fully engage in all of her vices without measure, even when Kyouya begs her to restrain herself in the aftermath of getting black marks.

* EveryoneHasStandards: Chris, like most followers of Eris [[spoiler:i.e. herself]], hates harpies, but she is taken aback by how some of the Church of Eris extended that hatred to all demi-humans, even the ones Eris likes.

* BerserkButton: Izuku hates it when people assume that Chika and Liza are just mindless brutes, when both of them are far more gentle and smarter than people believe (and probably are).

** Chris' first appearance [[spoiler:(and thus Eris')]] shows a nasty side of her as she insults Chika and Liza.

* DopeSlap: Megumin bonks Izuku on the head after he offers to reincarnate Wiz, after he had just done the same for Keel and his people without sufficient time to rest.

* LoopholeAbuse: [[spoiler:The Devil King exploited the letter of his deal with Wiz (she keeps the barrier protecting him powered as long as he doesn't hurt the innocent) by sending Beldia to camp near Axel, knowing that sooner or later the Dullahan would attack the city of his own will.]]

* FluffyTheTerrible: Izuku names his Behemoth "Komoe" in Chapter 19, apparently because Chika and Yunyun considered it "cute" and "adorable" respectively, while Liza considered it "small", so he combined both those kanji to name it.

* BrokenPedestal: Izuku's regard for Aqua (which had been eroded already) drops sharply when he learns that she sanctions the enslavement of demi-humans.

** Kyouya's duel with Izuku becomes the lynchpin for multiple changes: Aqua leaves the party and joins Kyouya's, while he keeps Gram but loses Aela (Clemea in the original), leading to [[spoiler:Beldia biting the dust when he comes to Axel after Megumin blows up his fortress with Big Bang, Keel being reincarnated and the fall of Axel's Axis Cult church.]]

* NiceJobBreakingItHero: Keel the Lich was going to allow Aqua to purify him so he could finally meet his beloved, and in exchange he would give her and Kyouya his treasure. Instead, Kyouya attacked him before he could speak out, only destroying him (thus ensuring he can return) and accidentally destroying Keel's beloved's corpse. Aqua then drew a slapdash seal that would prevent Keel from reaching out to gather the corpse's ashes and didn't try to purify Keel's body. And, finally, the two ran away when the Lich's minions attacked them. Had it not been for Keel being a lot more patient than expected and Izuku learning about the problem and fixing it, Axel could have been in deep trouble.

** When he uses it to restore Wiz, she becomes an [[WingedHumanoid Avariel]].

* LaserGuidedKarma: The Lyndon College mage that attempts to extort Megumin for Big Bang's secrets and then tries to kill her. She dies when Izuku jumps to protect her, meets a furious Eris in the afterlife, is reincarnated as a Dwarf woman and gets in hot water with the Adventurers' Guild.

* WorkOffTheDebt: Aela foolishly takes Kyouya's debt to Izuku, only for Kyouya to bail on her without even saying thanks. This pretty much forces her to join Izuku's team to pay it all. [[spoiler:Izuku declares her free of debt after they return from killing the Rookie Killer, considering her to have paid it off with her share of all the quests they have done, plus her part from Beldia's reward.]]

* FantasticRacism: At some moment in a past war, the harpies and lizardmen killed several races that Eris favored, and the goddess named them her enemies so they would get massacred while the survivors and their descendants were forced into slavery. Izuku understands why she would be furious, comparing the initial event to Germany and Japan's actions during World War II, but he considers that the punishment is DisproportionateRetribution. This usually gets extended to all demi-human races, even the ones that had nothing to do with the war.

* CameBackWrong: The reincarnation ability Izuku has as an Arch Druid has a few drawbacks compared to a normal resurrection, namely that the race, and sometimes ''[[GenderBender gender]]'', of the reincarnated individual is chosen seemingly at random, which can result in this sometimes from the perspective of the subject of the spell.

* IncorruptiblePurePureness: Much to the shock of the Cream Cafe succubi, Izuku is so pure that they can't even find what kind of girls he likes without forcing him to have erotic dreams.
