History Manga / UncleFromAnotherWorld

** Uncle learned about Rengoku from one of Hiei's attacks in ''Manga/YuYuHakusho: Makyou Touitsusen''.

* NewLifeInAnotherWorldBonus: Uncle doesn't realize until after he returns that his was [[spoiler:being able to communicate in any language]], because the message from God informing him of this was in another language (Mandarin Chinese in the anime). And his first desperate use of this power, to try to talk with the adventurers beating him up, gets them to sell him off as a rare talking orc freak rather than just leave him behind. Slightly Subverted in that Uncle may have thought his ability to talk to [[NatureSpirit Nature Spirits]] to get powerful magical effects was the bonus.

** Whenever Uncle invokes spirits for powers, they demand something in return. On a hot day, he invoked the spirits of ice to use them as a makeshift air conditioning device, and they demanded a cow's head or else they would cover the world in ice for 10 years. [[spoiler: They settled for a fish's head.]]

* RewindReplayRepeat: Uncle's recollection spell inexplicably works like a video player application, complete with pausing, rewinding, track skipping, and a TranslationConvention function, all of which are handy when trying to explain the context of his memories to Takafumi and Fujimiya. It can change viewpoint in 3D and zoom in to a obviously magical extent. It even has an EnhanceButton!

** Subverted when Uncle is told by God where to go to get more information when he first arrives in Granbahamal, but doesn't understand the message. Viewers with a memory will notice the name reappear later and be hoping he goes there, even accidentally.

* SelectiveObliviousness: Uncle deliberately sorts his inventory while Elf-san is talking with the [[HotSpringsEpisode:Purgatory Hotsprings]] owner about another visitor from Earth, thinking this is unimportant dialogue with an NPC. Viewing it later, Takafumi and Fujimiya disagree as it might have helped him get back home.

* TheresNoPlaceLikeHome: Despite losing fifteen years on Earth and being loaded with a bunch emotional of baggage, Uncle considers being back home a significant upgrade over Granbahamal. It helps that he has an easier time forming relationships in the real world and gets to keep his isekai powers.
* TranslationConvention: The native language of Granbahamal is incomprehensible to people from Earth and vice versa, with Uncle's ability to communicate with them (and by extension, Takafumi and Fujimiya being able to understand them) being given to him by the gods, which is translated into modern Japanese. These same gods also inexplicably spoke an entirely different dialect altogether that's rendered as Mandarin Chinese in Uncle's flashback sequence.

* TribalCarry: Upon his arrival to Granbahamal, Uncle was beaten senseless by three men who mistook him for an orc. When they realized he could speak human language, they tied him on a pole by his wrists and feet and carried away to sell him to a freak show.

* ShootHimHeHasAWallet: Upon being assaulted by the first group of adventurers he ran into in Granbahamal, Uncle tried offering them all of his money so they'd let him go. Unfortunately for him, these people have no concept of paper money and believed that he was trying to use an attack spell talisman on them, prompting them to beat him up even more. When he inadvertently invokes his [[spoiler:God-given gift for translation to suddenly speak their language]], they drag him off to be sold as a rare talking orc.

* MagicalLand: Granbahamal. Earth is one as well, but no one can communicate with Earth's [[NatureSpirit nature spirits]] except Uncle.

* MundaneUtility: After returning to Earth, Uncle uses his vast magic abilities for free long-distance deliveries, special effects in his Website/YouTube videos, free air conditioning in summertime, and getting women's discounts in movie theaters.

** [[spoiler: When Takafumi temporarily got magic powers from his uncle, he got turned into a dinosaur afterwards. Thankfully it only lasted for a day.]]

* RewindReplayRepeat: Uncle's recollection spell inexplicably works like a video player application, complete with pausing, rewinding, track skipping, and a TranslationConvention function, all of which are handy when trying to explain the context of his memories to Takafumi and Fujimiya. It even has an EnhanceButton!

* ShootHimHeHasAWallet: Upon being assaulted by the first group of adventurers he ran into in Granbahamal, Uncle tried offering them all of his money so they'd let him go. Unfortunately for him, these people have no concept of paper money and believed that he was trying to use an attack spell talisman on them, prompting them to beat him up even more.

** During one of her initial meetings with Uncle, Alicia does a SwordPlant while giving an introductory speech. Edgar and Raiga immediately chew her out for smashing the tip of their new sword against a solid surface.

* UnresolvedSexualTension: Fujimiya has an obvious crush on Takafumi and he does find her attractive, but she hasn't properly confessed and he resists the sexual tension between them because he thinks it would be weird to [[ChildhoodFriendRomance date his childhood friend]] no matter how obvious she's trying to make she wants that badly.

** After escaping imprisonment from a freak show, a bunch of cute animals he liberated surrounded him... but as they were starving, they attacked him, and he ended up killing them all, and eating them (he was starving too).

* AccidentalProposal: A RunningGag where Uncle offers one of the rarest rings in the fantasy world to certain people in his journey. While they are worth a great deal of money in that world, he is oblivious to the fact that such a gesture is translated to "Will you marry me?"
** In its own running gag, every time he tells Mabel one of the rings' recipients, that she can live off from money she receives from selling hers, she becomes incredibly defensive.

* ArborealAbode: Mabel lives inside a tree until the villagers tear her tree down and force her to find a job.

* ChildhoodFriends: Double-subverted. It seems like Takafumi and Fujimiya have this, but looking at Takafumi's memories reveals that she relentlessly bullied him incredibly cruelly. The double-subversion comes in that, like his uncle, he still considered her amazing and a good friend, one he remembered all those years later.

** There's also a mild jab at the [[ConsoleWars video game console wars]]. Takafumi is genuinely bewildered with how Uncle takes the rivalry between Nintendo and Sega so seriously, especially when the "war" between them ultimately didn't matter in the wider picture of Japan's gaming scene.

* WillTheyOrWontThey: Takafumi and Fujimiya are obviously attracted to each other, but a RelationshipUpgrade isn't happening anytime soon because Takafumi thinks it would be wrong to [[ChildhoodFriendRomance date his childhood friend]] no matter how obvious she's trying to make she wants that badly.
* WorldOfJerkass: Uncle spent 17 years in a fantasy world full of jerks who would beat him up just because he's ugly like an orc by that world's standards. He did make a few allies, but most of them started out hostile, too.

** There's also a mild jab at the video game console wars. Takafumi is genuinely bewildered with how Uncle takes the rivalry between Nintendo and Sega so seriously, especially when the "war" between them ultimately didn't matter in the wider picture of Japan's gaming scene.

** While Uncle is shown to be very knowledgeable about gaming and manga, befitting his being an otaku, this doesn't extend to conventions and tropes that became more mainstream ''after'' the TheNineties. This could be seen in how he mistakes what comes across to modern audiences as tsundere behavior for simply being a jerk.

** The {{Tsundere}} character is also deconstructed - Uncle straight up cannot tell that Elf-san cares about him. While he makes a lot of missteps on this, [[SurprisinglyRealisticOutcome it's hard to blame him]] considering that from his perspective, all she does is mock or nag him.
* DeliberateValuesDissonance: Both ways. On the one hand, Uncle initially struggled to make sense about the culture and social norms of Granbahamal. On the other hand, after returning to Earth, he finds that contemporary Japanese culture and trends have already diverged from what he was familiar with back in 2000.

* TakeThat: A mild one to ''Manga/KochiKame''. One of the first things Uncle wants to do after coming back to Japan after 17 years is to read some manga, being the geek he is. He wants to read ''Kochikame'' because "it's always the same story" so he doesn't have to worry about culture shock. (However, the manga ended in 2016 and Takafumi quickly informs Uncle about that.)

* MoodWhiplash: Things can go from hilarious to serious and from silly to dark at a moment's notice. In Chapter 28 there's the moment where Alicia accidentally exposes herself to Uncle, who then proceeds to quickly wipe out his memory of that to preserve her dignity, then this ends up leading to a hilarious conversation in which Alicia discovers she's ''older'' than Uncle, and ''then'' this leads to a much serious conversation about how precious memories are for Alicia [[spoiler:and how this made Uncle feels guilty about erasing some of her memories in their previous encounters]].

* There’sNoPlaceLikeHome: Despite losing fifteen years on Earth and being loaded with a bunch emotional of baggage, Uncle considers being back home a significant upgrade over Granbahamal. It helps that he has an easier time forming relationships in the real world and gets to keep his isekai powers.

* AssholeVictim: A variant between Mabel and the villagers. Freezing them in place and subjecting them to cold water torture sounds incredibly pretty; however, considering they all treated Uncle poorly and planned to make Mabel a slave, they’re lucky the latter didn’t just snap and offer them.

* There’sNoPlaceLikeHome: Despite losing fifteen years on earth and loaded with a bunch of baggage, Uncle considers being back home a significant upgrade over Granbahamal. It helps that he has an easier time forming relationships and keeping his isekai powers.

* TraumaCongaLine: Uncle's isekai was pretty much this: he started off with being sold as a talking orc to a freak show, for 3 copper coins, or 1/40th of the value of an used scrubbing cloth. He only survived by awakening his spirit powers, but being powerful often just led to him being treated like a more dangerous monster. Imagine seventeen years of similar treatment.

** A guardian whose job is done isn't needed anymore, as Mabel discovers.

* SequenceBreaking: Done unintentionally when Uncle managed to slay the fire dragon without going through Mabel's SideQuest to obtain her Frost Blade, which up until that point was supposedly the only weapon that could defeat the monster. He also does it later with Alicia's party by using a spell to detect and open a door leading directly to the dungeon's treasure room where the Rod Of Salvation is found, but having learned his lesson and not wanting to steal all the credit, he erases their memories of the room and leaves the rod in the room and helps them complete the dungeon the normal way.

** When Uncle and Mabel have illusions of themselves distract a group of knights that Mabel is currently working for so that she and Uncle can talk things out, their deception is found out sooner than expected. When they ask how they figured it out since the illusions are still fighting each other, they've shown to have detoriated over time, with Uncle's illusion now being oversized and fat and swinging his sword in the same way as Shell Shogun in ''VideoGame/AlienSoldier''.

** Whenever Uncle invokes spirits for powers, they demand something in return. On a hot day, he invoked the spirits for ice, and they demanded a cow’s head or else they would cover the world in ice. [[spoiler: They settled for a fish's head.]]

* SequenceBreaking: Done unintentionally when Uncle managed to slay the fire dragon without going through Mabel's SideQuest to obtain her Frost Blade, which up until that point was supposedly the only weapon that could defeat the monster.

* BalancedHarem: In the Granbahamal flashbacks, Uncle has three admirers and each girl has equally slim chances of getting with guy due to the series' ForegoneConclusion. Since all Uncle wants is to return to his world, no one ever makes romantic progress with him. Elf-San, the first girl, gets the most screentime and is the most overt, but in the end has no better a shot with him than anyone else.

* FantasticRacism: It seems almost everyone in Granbahamal are terrified of orcs. The immediate reaction to seeing one is extermination and double dealing an orc is considered acceptable.

* LookBothWays: Subverted as a VisualGag, then played straight, in the first episode. The Narrator of the series (the nephew of said uncle) was apparently going to get hit by a truck while crossing the street, but was then revealed to have made it safely across. Then it is revealed that the titular uncle got into the predicament he is in now because he was hit by a truck while crossing the street 17 years ago.

** The anime's [[https://www.youtube.com/watch?v=NFS7ZvqOO_A opening]] contains numerous nods to games released on Creator/{{Sega}} consoles, including (but not limited to) ''[[https://en.wikipedia.org/wiki/Shinrei_Jusatsushi_Tar%C5%8Dmaru Shinrei Jusatsushi Taromaru]]'', ''VideoGame/NightsIntoDreams'', ''VideoGame/GuardianHeroes'', ''VideoGame/SwordOfVermilion'', ''VideoGame/GoldenAxe'', ''VideoGame/StreetFighter'', and ''VideoGame/SonicTheHedgehog''.

* BalancedHarem: In the Granbahamal flashbacks, Uncle has three admirers and each girl has equal amounts of screen time with him. Since all Uncle wants is to return to his world, no one ever makes romantic progress with him.

* IdiosyncraticEpisodeNaming: Each episode is titled after a line of dialogue from Uncle.
