Post Isekai Concepts

I Reject This World! ~Isekai Rebirth~

War. Greed. Hatred. Death. Kobayashi Makoto is sick of this world. All across planet Earth is suffering and destruction. The corrupt elite of society hold back humanity's progress by fighting to secure their status and wealth. Earth's ecosystem is dying as civilization grows out of control. For every single act of good, countless evils take place each and every day.

"Humanity is vile! Earth would be better off without us!"

Kobayashi Makoto rejects this rotten world with all of his soul and is given a chance.

"Will you 「Ｒｅｓｈａｐｅ　ｔｈｅ　Ｗｏｒｌｄ」 with me?

A Goddess appears before him, promising a new beginning for the disenchanted youth. He is reborn in another world, a land called Ise-kai, in the body of a six year old child. Living with his mother (Goddess), Kobayashi Makoto begins his journey to 「Ｒｅｓｈａｐｅ　ｔｈｅ　Ｗｏｒｌｄ」.

Isekais are shit
That looks like something a 15 year old would write

>Isekais are shit

Fuck you.

>That looks like something a 15 year old would write

eh when you're right you're right

I have one that I'm kind of writing but haven't actually worked on in a while.

MC is a bit older than the usual isekai (write what you know) but only particularly talented in languages. After coming to a new world, he gets a suit of adamantium armor which is very strong but not heavier than steel. He appears in a new world type continent, and is soon involved in colonial disputes. He ends up forming his own nation, first as a city that just happens to not be associated with any old world nation, and then eventually as an empire. Along the way, he picks up a spirit waifu to be the genius loci and god of his empire, other waifus to represent specific deities and minority groups, and also earth magic which he uses primarily to build infrastructure. It's also (intended to be) a sort of theme park story, where he goes on adventures on different continents and basically lets me show off my setting.

A boy falls in love with a girl. Unable to confess

Found this interesting (and humorous) twist on the isekai genre.

Basically, it's where fate summoned a bunch of these morally questionable high schoolers to save the world.

Well, they did, and now they're content to stay in that world, and they're all using their powers to start empires, build harems, resolve petty grudges, and in general most of them are causing a lot of chaos in their conflicts with each other.

So whatever force summoned all of them desperately looked for something similar to them that could stop their tyranny, another outsider similar to them capable of preserving order and the law.

So, a cop is summoned. Or, if they're a bunch of highschoolers, the principal of their highschool got summoned.

Can this cop arrest all of the them/can the principal put them all in detention?

>Along the way, he picks up a spirit waifu to be the genius loci and god of his empire,

Fuckin love that shit.

It's shit.
This sounds like a fun premise for an isekai comedy/parody. I can already see MC being a police box cop who happened to know all the troublemakers before they traveled to that world, and try to get super powered teenagers to stop their shit and go back home.

Rayearth is bad

Another user had a decent idea
>Edgy teenager gets trucked
>decides to terrorize everyone as an evil overlord rather than be a hero
>is eventually stopped and sealed away by a group of heroes
>the seal actually sends him to his previous world
>time passes
>he now has a successful job, wife and kids
>without his powers and no evidence of their happening, he treats his memories like some chuuni fantasy he had when he's younger
>the seal has been weakening
>protagonist is forcibly returned to the isekai world
>An Ancient Evil Awakens
>and wants to get back home

A fantasy world is in state of creation by "gods" so some laws are not completely ironed out. There is "patches" falling down from the sky periodically but sometimes weird things still happen.

One of the mages while trying to overcome a teleport ban taps into our universe and spirits away souls/minds of a couple of people. Though he doesn't even know that this thing happened and thinks that his spell just fizzled.

Characters find themselves in newly spawned bodies of monsters and need to survive in the world. And while some of them may have got pretty powerful bodies the truth is they are really small fries in the grand scheme of things. Which they will find out pretty soon. Then characters come up with different survival strategies try to integrate in the world or try to return back to our world.
...
In the end those who wanted to come back may reach for one or even all the gods and find out that they actually never left and wizard's spell just copied their minds.

Holy shit I need this in my life.

I like the idea but it seems like it would get boring quick because it's just another 'lazy/goodguy maou' story.

All the players of a certain videogame get pulled in the game's world, a la Log Horizon.
MC is a low level player with no particular talent at the game whatsoever. He doesn't get an OP speshul power, nor a super sekrit hack. He gets nothing, he's just a bad low-level player.
But he's fucking good at economics, so he cons a kid into giving him a lot of money to start up his investment bank, and then proceeds to climb every ladder in the world with the power of money.

I feel like this would be better without the overly long backstory :
>Teenager gets trucked (possibly after confessing to the girl he liked or something similar)
>Is reincarnated as the chief of the Big Bad Evil Kingdom.
>The only way for him to go back home is to shatter the balance of the world to the point where he can actually travel back through dimensions.
>Obviously, upsetting the balance of the world force him to act as the evil bad guy.

And for lore purpose :
>Turns out the last big bad was the same, and demons simply keep summoning people and get them to try to destroy the world.

People play a VRMMO which transports them into an isekai, they can log out as they please and there is no permadeath for players. The native inhabitants fear the immortal demigods who resurrect after death, descend as they please, and treat life like a game

Being an economist while trapped in an MMO would suck

>money is used to purchase goods and services
>money is obtained from killing monsters
>there is an infinite supply of monsters and therefore money
>since the mmo is real life there are no external devs to create money sinks and stop the hyperinflation

>Guy gets Truck'd
>Wakes up in a test tube
>"This one is a success! Open the tube!"
>He's the first successful revival of the extinct Human race by a race of jellyfish-like aliens
>It's isekai, but not a totally different universe. The jellyfish stole all the bones they could from Earth, and attempted to revive the race as they were put down by something horrible
>He is put in various breeding programs in an attempt to find a proper mate that can help him restore Humanity, but things never work and he doesn't get a harem of alien monsters.
>He's literally the only Human left. No humanoid aliens, no other Humans, only freaky monsters in space.

It's like a regular isekai but the protagonist is a fan of Rance.

Considering he has a reason to return to his original life (his family), the MC would probably try his best to leave the fantasy world as fast as possible. Combine that with being a former evil overlord, he'd employ "the means justify the ends" methods. And if you think about it, he has not attachment to the isekai world so he'll also probably be an edgelord while he's in it.

>writer has a habit of trucking characters
>eventually makes a spinoff of the fantasy world every trucked character is sent to

d-does this tale have a happy ending?

MC has the ability to enter any isekai as much as he want, but once he enter another world he wont be able to trace back to his home world. MC age remain the same as the first time he uses his isekai ability.

MC live through many different worlds for atleast nearly 300 years already, desperately look for clue. One after another world hoping it has any connection to his home world.

>mc is a maou reincarnated on earth
>gets transported to his world as a hero
>no one knows
>it's 100 years later and a new maou
>he's doing everything differently and mc hates it
>adventures to ruins for treasures of his previous life

/tg/ does it best
1d4chan.org/wiki/Stranded_in_fantasy

Yes and no. He lives a healthy, extended life due to alien tech, providing great insight into both his past culture and the alien's cultural effects on himself, but he still grows old and passes away just before the second successful revival project happens, reviving his girlfriend from before he was truck'd.

a life of isekai MC after came back from other world to japan again

it's all how he deal his life in japan with all his superpower gained from other world

The best you can expect from an isekai is a good start.
But I've never seen an isekai hold up steadily until the end, even the "best" turn to utter shit by the time they reach conclusion.

>shounen gets hit by a truck
>goes into another world
>is very spiteful about dying
>has to rebuild life from ground up
>falls in love with girl
>girl is actually the truck that sent him to the other world
>Can out beta protag overcome his spite and accept Truck-kun into his heart????

MC isekai into his crush's ideal fantasy world.

well, that's an interesting idea, user

>MC gets sent into another world
>realizes that there's no internet and becomes depressed
>learns how to fight
>mans the fuck up
>becomes a criminal and leads a free life full of pillaging and murder

A reverse-isekai sci-fi / conspiracy anime where the plot follows someone else dealing with an overpowered isekai instead of the isekai character themself.

Plot follows 20-something college dropout / NEET / urban explorer in Tokyo or Osaka. Starts noticing weird stuff in abandoned subway stations and other underground places - as if lots of people have been using them or moving around in them. Sets up cameras, they disappear. Meanwhile, city is in state of agitation due to a rash of disappearances thought to be the result of a Yakuza civil war / coup.

MC starts investigating, finds increasingly bizarre and impossible things. Follows people underground only to have them disappear in dead end type of stuff.

First episode ends with MC exploring a pitch black subway tunnel. He turns a corner with his flashlight... to illuminate a teenage girl standing in the pure blackness.

"It'll be easier for you if you don't run."

Next episode timeskips ahead.

It is revealed that the MC is now working for the girl, who is the leader of a technologically advanced organization that has traveled to our world from another. The rest of the series follows the MC as he works for the organization in increasingly violent and far-reaching conspiracies. The mysteries of this organization, the world it came from, their leader, and their designs on our world, and why the MC works for them at all are revealed piecemeal over the series.

The leader of the organization appears as various young girls (because anime HAS to have attractive girls to sell), but is actually a giant cyborg-brain of unknown age who controls many bodies and systems at once. She has access to seemingly endless amount of technological knowledge that she uses to manipulate world events and gradually establish greater and great control over the world. Think of an Overlord type character like Ainz, only we're the shitty underpowered world that is getting stepped on.

>his crush is fujo

The plot would also branch out to incorporate the stories of other people who gradually become aware of the isekai organization and try to oppose it.

MC is bard who lives in a world where tropes are a real thing and countless of heroes are created everyday.

These heroes are your typical knights saving the princess, japanese highschoolers being summoned, and chosen ones being selected from the one of many prophecy.

As a bard, the MC tries to collect as many of these stories as possible.

After finding common patterns and spotting irrational logic behind these stories, the MC decides he can be a better hero by not making the same mistakes as the "real heroes".

Hijinks ensues, and he's faced against evil badguys, comedic relief character who also happen to be strongest character, heroes from all different type of genres (fighting, JRPG, card dueling), and even the TRUE protagonist.

it's a game I'm making

>his crush's magical realms

an user, tired of reading shitty isekai stories, decides to write his own.
he sets up a believable world full of history and culture, rich with customs and technologies developed by infusing magic and technology.

He creates flawed characters that will grow and face hardships.

As he is finishing the work, he goes to sleep, and awakens in the world.

he is happy cause he gets to live in a reach fantasy world of his dreams, but to his surprise another person gets transported.

Its the MC of an Isekai he despises cause it gave him everything on a silver platter, since user is pretty much weak and useless to survive, chad mcthundercock offers to travel with him and protect him since he is super op.

as they arrive at the first village, chad gains 3 girls instantly for his harem.

The story slowly shows anons losing sanity as he is forced to travel with chad and have him repeat all the shitty isekai tropes he hates.

Eventually user confronts a literal god, that got pissed at user for constantly shitting on his isekai story, tells him the entire ordeal was to teach him a lesson.

user does not take this revelation well.

He either goes full raistlin or resigns himself to be chads tag along while chad fucks his harem that now numbers the 1000s.

Fuuka isekai spinoff starring Fuuka after she got trucked. Here, Eris reincarnates her into Fantasy Australia and she becomes a singer, fighting monsters and preventing hijinks through songs.

>Guy dies
>Gets revived as a pinball machine in a semi-fantasy WW1 setting

One humvee of US marines gets transported to magical shitland during a sandstorm.
They try to get the fuck out of there instead of jacking off and making harems, while slowly running out of ammo.

>MC constantly gets hit on by bishounens of all races
>he has a harem of powerful bishounens
>there is also one girl in his team
>she's lesbian

>MC gets summoned
>MC is told that a that prophecy says person from another world has to be summoned to defeat the demon king
>MC is super hyped. always dreamed of being isekai'd
>MC goes out to level up and gain companions
>Turns out MC has a justice boner. White knighting everything he can
>Over time as he get stronger, MC's white knighting gets more and more extreme
>Justice boner get hard to the point where its "You're with me or against me"
>People are starting to get scared of MC, he's starting to act like a tyrant
>King cannot allow this any further and attempts to stop MC and his companions.
>MC sees the King as a threat and usurps the throne
>Commoners are scared shitless, They face cruel punishment for any signs of defiance
>MC is nicknamed the Demon King
>In response of these dark times, a single villager takes up arms in an effort to over throw the tyrannical Demon King.
>Thus is the birth of the Hero.
>Part 1 end

I like how this concept is arrogant enough to assume that there are no flawed isekai MCs and then goes one to write one of the worst isekais concepts ever

I think this is the most ironically shit isekai I've ever seen

Now we're fucking talking.

Taking as a base.
>demons try to make him emphatize with them ("oppressed demons theme" etc.), he gets demon waifus and slave waifus. So he genuinely thinks it's all a game and he's doing the right thing to go home.
>Of course, he's just being manipulated. The charade progressively falls apart as the war goes on. Demons are obviously evil and humans have very good reasons to hate them, slaves only love him because being his slave is better than being the slave of any other sadistic demons.
>MC eventually realize that this is all very real and has a conscience crisis. Leave the demons and try to live alone in peace with his former princess knight slave who eventually abandons him.
>Of course this does not goes well as demons keep oppressing humans and summon another isekai protag to continue the war.
>MC fights back as a sorta antihero and gradually teams up with his former ennemies to push back against the demons, his former slave is among those heroes.
>Start forming genuine friendships with them, even though no one forgive him for the awful things he did.
>Beat the isekai protag, but dies from his wounds in the arms of his waifu, only experiencing true love in his dying moments.
>The heroes use the demon's summoning circle for one last ritual.
>MC now lives between dimensions, appearing only in time of needs to protect the world he once tried to destroy for all of eternity.

MC powers though a standard hero plot, kills the devil king, claims all his loot, then takes everything he gained in the other world back home once he unlocks isekai magic. He has powers no one understands or can fight against, so he's basically Hancock but things keep escalating because he thinks he deserves his own country now for all the shit he's put up with. And he's also spent the last few decades dealing with monarchs and warlords, being both at times.

He sends people to the fantasy world if they try to fight him and eventually some of them get strong enough over there to come back and fight him.

Sounds like this this series was concocted specifically with me in mind, gathering everything i hate the most in a single concentrated piece of garbage.

I once posted one about god transporting an editor into isekais stories to fix their shit through any means necessary.

what is arifureta after stories.

murderhobo is best protagonist.

Fantasy but without the isekai, rpg conventions, self insert MC, and actually good writing

>but without the isekai
>He is reborn in another world, a land LITERALLY called Ise-kai

>good writing
you can remove the transported to another world theme from an Isekai, but good writing completely goes against the genre.

>hating /ss/

>actually good writing
>rpg conventions
>self insert MC

If i see another isekai with an adventurers guild with fucking rankings and videogame shit again I think I'll go on a rampage

The other part of the series would be the relationship between the isekai leader and the MC.

Basically, the isekai leader is a robobrain/pseudo-AI built by the remnants of an advanced nation in a post-apocalyptic world to conduct research and wage war. At the behest of its creators, it invented a way to escape from their ruined world to a new world by destroying their old world to create the energy needed for the transferral process.

Its creators had absolutely no problem with this plan. Unfortunately, it was not quite as loyal as they believed, and only transferred itself a few others, leaving its creators (and the rest of the world) to be destroyed.

At the start of the series, the isekai AI is utterly manipulative and sociopathic, and basically just toys with the MC and others, and basically plans to mindslave the entire planet. However, it also likes to just mess around and explore things in the world, because it never had any sort of childhood or normal life. Over time, however, it begins to develop genuine attachments to the MC and the planet, but still intends to conquer it as a benevolent dictator.

In the show's climax, everything comes out in the open and the world divides into a massive worldwide civil war as in every country the isekai's agents battle against people who she hasn't been able to subvert. The MC, who comes to care for the isekai but wants her to abandon her goal of conquest, has to figure out how to stop the war without the isekai getting killed and without her winning and taking over everything forever.

In the middle of this, a bunch of people from the isekai's world, which actually wasn't totally destroyed, come over here and immediately begin to show our world what total war with technology 300 years more advanced than ours looks like, forcing our world to unite with the isekai to fight them.

...

I think it would be better if the heroes were inept, so the protagonist actually has to work hard to keep them on the rails

Priest from fantasy world finds himself isekaied in our normal world while keeping his holy powers . He decides that this sick world needs to worship his God so he starts publicly killing heretics and showing his holy magic to convert people.

warhammer fantasy isekai

a japanese neet who only plays dragon quest and reading cliche isekai story one day find himself in warhammer world while walking to buy more isekai. There, a beautiful goddess with blue hair and wings called him the chosen one and tell him to unite all race to fight against the demon king.

Little does the neet know that the goddess is Tzeentch in disguise and he was bored so he summoned a human from another world for his own amusement. And so our hero first arrive in Athel Loren, appear before a showering female wood elf and was responded with a arrow in the arm, which made him flee in terror to the nearby settlement: Cacassone. The naive neet was then treat to shit by the nearby bretonnian knights and so he decided to use his modern world knowledge to survive. He tried to recruit the local peasants just so he could overthrown the local "evil corrupt lord" only to get btfo by the peasants since they are very loyal. Beastmens then attacked which neet fight back and slain the Minotaur out of pure luck and was recruit by the knight who crushed the beastmens with little efforts.

As you can see, this is a story of the neet's suffering at the cruel world of warhammer where nothing goes his way, and he won't die so easily since Tzeentch had planned for his misfortune where he will suffer to the very end.

Hitler goes to a fantasy world at the end of WW2 and saves everyone from a jew who also went to the fantasy world but came from the future to find and kill Hitler before he could return to earth and retake Germany with Thule magic

how does this story last more than one chapter without the moonman getting killed or worse?

"In a certain fantasy world , a ritual were commmenced at a castle to summon demon lord by an unknown masked group. A group of heroes came try to stop the ritual, but they already too late. a great dark beam came from the ritual cicle with massive shock wave, throw everyone at site, the afterexplosion dust cloud revealing a figure with horn, wearing a shirt and shortpants, he's wearing ad700x , his posture is like were sitting on a chair with leaning his to two hand on a table, then he said " RUSH B, Dont stop"

One concept I thought of is a guy who starts off trying to get back home, except he just woke up in the new world one day instead of dying and he begins to wonder if his previous life was all just an incredibly dull dream.

Guy gets summoned to a medieval world.
>The world is recovering from a battle between a group of summoned "Heroes" and Demons which was actually human plot for a Genocide to eliminate aberration species.
>MC has no special powers.
>Wants to come go home but meets a group of street urchins and decides to stay and look after them instead.
>MC works as a hard laborer during day and acts as a thief during night to earn money for the kids.
>Royal house finally gets a whiff there has been a new summoning and wants to get their hands on MC for evil plans.
>MC realizes that the nations heroes saved a century ago is shit and goes on a quest to re-summon the heroes and start a revolution.

>A bunch of people get isekai'd
>They all love it in the new world, because their old life sucked and here they are pretty much kings and heroes.
>Except for one guy who doesn't care about this wish fulfillmint bullshit at all and just wants to go home.
>He finds out that if he wants to go home, everyone needs to go back too.
>Series is about the MC literally dragging everyone kicking and screaming back to reality, because fuck this unhealthy escapism garbage he wants to go home.

Just like Touma he is too unlucky to the point that death would be lucky for him.

I'd like a reversal where the hero from another world dies from their own truck-kun equivalent and then comes to a world were he must work for a living

Because Tzeentch was playing with him. He and Ranald basically made him live the impossible while watch him fail just for the lulz. The neet would later get in trouble with a dwarf (result in a grudge), chased by a vampire yandere, chased by a bunch of goblins sent by Skarsnik even tomb kings wants a piece of him. So instead of getting harem, he kept making new enemies that wants to kill him. Well at least there's this witch hunter who kept gave him quest to kill shit and provide him with gears.

>MC gets truck'd
>Meanwhile, a god who was supposed to look after an alternate dimension wanted to slack off
>Nab MC's spirit before he was reincarnated
>Put him in stewardship over the dimension the god was supposed to look after while said god goofs around
>MC now needs to look after the world
>Turns out, MC cannot do anything but try to influence events and raise heroes to solve calamity after calamity.
>Shenanigans ensues.

>isekai where the MC and the person who trucked him / her both die and get transported
>they have to work together to get back
blegh

ha ha whoops

t. mobileposter

is this supposed to be the NTR isekai?

Pretty much, but MC is a god now, so I would think he would just curse anybody who tries to get into his 'waifu's' knickers.

How is the MC not Hitogami from Mushoku Tensei?

>Over clicheed Paladin dies due to a Demon Lord in a fantasy setting but kills him too.
>Is reborn into our world.
>No knowledge of cars, phones or anything of the modern era.
>He has to go find a job and gets an office job.
>Demon Lord respawns into our world as his boss.
>He finds his old party members are reborn too but are completely different people except for appearance.

Sounds suspiciously like メイデーア魔王転生記, except this had 3 demon kings reincarnating in modern Japan and the hero had to come over and murder them back to their previous world

>Maou is reborn as human peasant girl in poor village
>Improves quality of life for family and/or saves village thanks to intelligence/powers
>Becomes content with her life until village is conquered and sacked by hero's kingdom

...

>protagonist is the usual hero in fantasy world
>some moron otaku gets isekaid into his world in front of protag
>otaku takes it upon himself that he must defeat the demon king
>protag faces his greatest challenge so far as he must guide and protect the otaku on his adventures, while the otaku thinks of himself as the chosen one
>even better if protagonist is female and otaku thinks she is a tsundere for him

Isn't that just tactics advanced?

yes based marche is the only one who can save the industry

>MC get isekaied in a medieval fantasy world.
>End up in a remote village, surely this is his chance to improve everyone's way of life with superior modern knowledge !
>Everyone already knows about crop rotation, they even have a water-powered mill.
>MC then realize that he can't replicate a single thing from his world because of the lack of ressource and his lack of knowledge (he is jus an otaku). He can't even read, he can only understand their sppoken language.
>Ends up working as a farmhand for a wealthy peasant family.
>Story is about his daily life in the village, and discovering all the details of this very small part of a much bigger world.
>Ending is him finally coming to terms with things and becoming a productive member of this agrarian society by teaching basic arithmetics to the village's children after learning how to read.

The furthest he goes is impressing the local noble with his extensive knowledge of strategy and tactics, only to realize that putting those in practice it another matter entirely.
He still gets invited at their table regularily.

yeah, let's break his brother's legs with a hammer.

And when they come back everyone else murders the shit out of him for ruining their life.

>MC turn all the dishies intro traps and crossdresser.

*bishies

Has nobody do a planeswalker-focused kind of thing in these isekai works? Plane jumping seems to be a pretty obvious thing to play with here.

sounds boring

the entire appeal of isekai is the setting

What is Arifureta After Story

The story takes place in a world that exists as a nexus of fantasy tropes. The world is a chaotic place, having heroes summoned is something so common that the moon has been named "Japan" after a famous hero summoned from America saw Chinese writing and called it "moonrunes", a demon king rises about once a month and spreads havoc throughout the world, dragons kidnap princesses for teatime companionship, and the number of fantasy races are in the thousands.

The Story, if you can call it that, completely disregards everything about the setting for the most part and focuses in on the Mages Guild, a collection of wizards, Mages, and other assorted magic users, the greatest of whom sit at the very pinnacle of magic, long since having surpassed the gods and eldritch beings of this magical and expansive universe. Every day the Mages congregate in the great halls and... Well, they don't really do much of anything!

It's a gag comedy about ridiculously OP Mages living in a crazy fantasy world who just spend half their time chatting about random inane issues like the color of hats the apprentices must wear this year or who turned all the swords in the warriors guild into kittens!
Featuring completely plagiarized characters from /tg/'s Mages guild such as:
>Antruthius, the senile Archwizard
>Conspierre, the Master Conspiromancer
>Lupa the Flesh warper, creator of nightmares
>Soros, the Head of Divination
>Friya the Crow, a powerful witch
>Noel, the tsundere head of Pyromancy
>Lord James, inheritor of the Red Shadow
>Mortimer the giant butler
>Noone Listed the undead Elven thief
And a bunch of other characters I can't remember since it has been a few years now!

But that would accomodate the development of several settings that might be more suitable to a short story, think Kino. Also, although the plot may differ, isekai worlds seem to be generic as fuck as of late, there's not much at all that break the typical Tolkien or DnD fantasy.

I have my own autistic isekai fantasy in my head. The MC and his whole college class get isekai'd by aliens and set up as kings and nobles in a feudal world by aliens as part of some social experiment the aliens are running. The aliens also stop their aging process.
I've done autistic amounts of worldbuilding in my head, and also more autistic amounts of research to make sure everything is semi-realistic and consistent.
There's no magic or dragons or any of that shit, it's all just politics, management, war, througn various ages.

>scientist gets isekai'd by truck
>in another world he learns magic is real
>proceeds to learn magic in order to gain immortality
>uses any means to get to his goal, no matter how many people die or civilisation are destroyed
>immortality is just the first stetp in his search for knowledge of existence
>conqueres all of the multiverse in the process
>at the end of his journey he is omniscient but ultimatly bored

>truck-san does its job
>MC turns into a big black nigger

>MUH MUSKETS

shit m8 i forgot

Isekai religious war
>Isekai god summon other people to be their champion to combat evil and gather believier
>Each person get their own type of blessing ( War god's champion got super strength, Earth god's champion got ability to control animal...)
>The more believer a champion gather, the more powerful their blessing get
>MC is the champion of the commerce god
>His power is to take and swap a object's "value", for explain: swap value between a pebble and a gemstone, making the gem useless and the pebble more valuable to other. MC also can swap their value back.
>To gather believer, other champion start doing heroic deeds like defeat devil or healing people, while MC just straight up trick other and gain a shiton of money and treasure.
>MC use those money and treasure to fund a country, become the hidden ruler of said country. Through laws, propaganda and more trick, MC turn the entire country into believers and start spreading to other countries, either by invade or convert.

About MC's power: a object got it's "vaue" change still retain it's usage, for explain : if a sword and a stick got swap, other will be caution to the stick and ignore the sword, but will be surprise when they see MC use a "stick" to slash them into pieces.

Moreover, MC's power affect a person sense of value, so if a person don't know about the object which value got swaped, they will only see the original.

This sounds genuinely funny and fun

>average 'nice guy' isekai MC comes into possession of several slave girls
>they do some adventures with typical harem hijinks
>some time later he finds a way to release them, but learns that their 'cute and loving' act was forced on them by their previous owner through slavery magic
>in reality they hate mc's guts and will fucking murder his virgin ass the moment he gives them enough freedom to do that
>(normal end) he never sets them free and lives with them the rest of his life under constant guilt and fear
>(true end) the moment he sets them free they fucking murder his virgin ass and live off his riches happily ever after
>(bad end) the moment he sets them free they beat the shit out of him, cast enslaving magic, set it to super gay mode and send him away to earn more money and then live off his riches happily ever after

A high schooler who's really into making maps and travelling suddenly gets hit by a bus and is whisked away to a fantasy world.

After learning the bare basics of the world, he decides to gear up, and travel around the world, making maps and selling said maps for the betterment of their world.

He gets to learn about the many different cultures in this world, and while many girls fall for him, he always leaves for the next destination without notice.

It's basically Golden Boy, except it's in a fantasy world, and he really likes maps.
He also similarly has a rad mountain bike that came with him when he got hit.
