✦ THE GRAND ISEKAI ✦

Twenty souls. One new world. Eight billion viewers.


Every thousand years, the gods roll the dice.

This time, they decided to put on a show.


The Premise

You have died.

It is a quiet, gentle kind of death, and it ends in a place of endless white, where a luminous being smiles at you with warm and unhurried kindness. She tells you that you have been chosen. A world called Aethelgard is in danger, and it needs a hero.

You are not the only one. Across the globe, twenty people have just died, one from each of the twenty greatest nations on Earth, and each of them has been given the same offer.

You say yes, of course. Who wouldn't?


The World You Wake Into

Aethelgard is a land of old magic and bright banners, and at its heart stands the Dicathen Empire. It is vast, ordered and formidably competent, and it borders every other realm on the map.

In the Magical Kingdom of Lunas, a rift has torn open in the sky. Demons pour out of it by the thousand. Dicathen’s armies hold the line, and they hold it well, but the Empire’s King can read the numbers and he knows that it cannot last.

So he orders the summoning.

You open your eyes in a hall of white stone and torchlight, surrounded by nineteen strangers who are as bewildered as you are. The Empire’s mages bow. The King welcomes you, calmly and professionally, as the Called.

He does not throw you at the front, because Dicathen is not that kind of empire. Every one of you, whatever strength or weakness the goddess gave you, is sent to the Empire’s most prestigious Academy, to learn, to train and to prepare.

The war will wait for you. It will not wait forever.


The Part They Haven’t Told You

This section is for the player. Your character will never read it.

You believe this is a genuine isekai. The goddess, the summoning and the quest to save the world are all real to you.

But it is also a television show.

The gods’ latest entertainment is the biggest broadcast in history. Every step you take, every spell you cast and every foolish, brave and tender thing you do is streamed live to the entire planet. Billions of people watch. They have favourites, and rivals, and fan wars, and betting pools.

🎭 What your character knows 📺 What the audience knows They died and were reborn. They are watching you live. The goddess chose them. Casting chose them, for their charisma. The Empire needs a hero. The odds on their survival are 7 to 2. A lucky coincidence saved their life. Viewers paid to send it. They are fighting for a world. They are also fighting for a nation’s pride.

You will see both layers. The adventure is told sincerely, from inside your character’s heart. Alongside it, you will read the world’s reaction to everything you do.

[LIVE CHAT] xX_Valkyr1e_Xx: he really just said that to the headmaster 💀 Lena_from_Osaka: I'm crying. why am I crying. it's a SCHOOL SCENE bet_boy_44: anyone want to take 3 to 1 that she tops the rankings??

[COMMENTARY] “And there it is. She has no idea that sixty million people are on their feet right now.” “She doesn't even know she's good at this.”


The Broadcast

Alongside your story, the following will be running at all times:

  • 🗨️ Live chat is a river of memes, panic and in-jokes from every corner of the Earth.

  • 🎙️ Commentators are a hype-driven host, a dry analyst and a pundit from every nation, and they all argue about you.

  • 📰 The news wire carries headlines about what this show is doing to the real world.

  • 🎲 The odds board covers every wager on everything, paid in points and never in cash.

  • 💌 The families are the people back home who grieved you, and who are now watching you live.

The audience is not only watching. The audience is fond of you, and fondness has a price. Viewers spend their points to send gifts, and those gifts will reach you as lucky breaks, kind strangers and well-timed miracles. You will never know who sent them.


Your Journey

⚔ Act I: The Academy. Learn magic, make friends and rivals, climb the rankings, survive the tournaments and decide who you want to be. The war is far away, and the show is at its funniest.

🔥 Act II: The Front. You graduate. The training ends, the Empire sends you into the war, and the alliances you made will be tested.

🌌 Act III: The Rift. The crisis peaks, and the truth about this world begins to come apart in your hands.

👑 Finale. One of the twenty will be crowned. The crown is not decided by who is strongest, and it is not decided by who is most deserving. It goes to whoever the world loved most.


The Gifts and the Burdens

Before you left the white room, the goddess weighed you.

If you had little going for you, she gave you a blessing, such as a second wind, a talent for magic, or a way with beasts. If life had already given you every advantage, she gave you a burden, such as a body that cannot hold magic, a face that cannot be forgotten, or a luck that fails at the worst moments.

Everyone attends the Academy, whatever they were given. The Empire believes every hero has a role, and its mages will find yours.

Your burden is not a punishment. It is the reason the audience will remember you. 😊


One Law

There is one rule in this story that matters more than any other.

What the audience knows, the world must never learn.

If anyone, anywhere, speaks the truth of the show aloud, they die instantly. Everything that was theirs vanishes, and the world forgets that they were ever there.

You may wonder. You may suspect. You may feel, at the oddest moments, that someone is watching.

But the day you work out what is going on, you will find that you can never say it to anyone.


Who Will You Be?

You are one of twenty. You carry a flag you didn’t ask for, and a story you can’t see the edges of.

Somewhere on Earth, a mother is already watching you. Somewhere in the stands, a stranger has put their points on you.

The goddess is smiling, and the cameras are rolling.

Step through the white door. Make them love you.


✦ The Grand Isekai is a tale of sincere adventure inside a satirical broadcast. Every contestant starts the story having just died, and you decide how your character’s story began. ✦

GRAND ISEKAI TV SHOW

  1. Premise Every millennium, the gods roll the dice for their entertainment with their subjects. This time, in 2026, they have decided to make it fitting to the current state of the world. What would fit better than a TV show? Twenty recently deceased people, one for each of the top 20 countries in the world, are selected to be isekaied into the world of Aethelgard. Everything that happens is broadcast and uploaded to every major platform. The contestants each represent their country, and the whole planet is watching. The contestants themselves have no idea. As far as they know, they died, met a divine being, and were reborn into a fantasy world to save it. Meanwhile, billions of people on Earth comment, bet, argue and cry over every step they take. The two-layer tone The story has two layers that run at the same time: • The Adventure. Played completely sincerely from the contestants’ point of view. The stakes, friendships and losses are real to them. • The Broadcast. The world’s reaction to the adventure: commentators, live chat, news, betting odds and fan wars. This layer is satirical, fast and funny, and it is the primary source of entertainment in the game. The Thousand-Year Games This is not the first time. Each millennium the gods choose a format that suits the age. Past games were staged as epics, pilgrimages and tournaments. The 2026 edition is the first to be televised, and the first with a global audience watching live. Aethelgard’s own history is full of legends about “summoned heroes” who arrived from nowhere, did great deeds and vanished. Those legends are the ruins of earlier seasons. In earlier eras the heroes may also have believed their quest was real, which would make them the original unknowing contestants.
  2. How the Show Works Broadcast • Anomalous footage. All broadcasts and footage exist in digital space through magic, not technology. Governments cannot tamper with them or track them down. • Outlets. YouTube channels, a subreddit, Facebook pages, and even a dedicated cable channel. No company can take these down, because it is the will of the gods. • Scale. Because every contestant represents a country, the show became the single largest IP ever. National pride, betting pools, fan wars and diplomatic incidents all follow naturally. • Hidden from the cast. Neither the contestants nor the people of Aethelgard know about any of this. The angels The angels act as ambassadors to the gods. They represent the gods’ will and speak for them. They also run the production. Every part of the journey is recorded, and the angels handle editing, cut out undesirable footage and produce the music. The Heavenly Choir composes the score themselves, so it is always the best possible music for the celebration. Example production staff: • The Host. A lead angel who fronts the show for the Earth audience. The Host is never seen by the contestants. • Casting angels. Each contestant meets one casting angel in the white space. To the contestant, this angel appears as a gentle goddess, guide or fate-keeper, in the classic isekai style. • Editors. They decide what airs. A scene can be cut, reordered or given a different soundtrack to change what it means. • The Heavenly Choir. They provide the music. When the score swells, something important is about to happen. • The Angel Delivery Service. Logistics and merchandise. They are the only channel through which viewers’ points turn into physical goods. The angels should never be simply evil. Give them real enthusiasm and genuine affection for the contestants. They love these people the way a fan loves a favourite character, and that is exactly why they will watch them suffer if the ratings are good. Viewer points and the Angel Delivery Service Viewers earn points by engaging with the show. Points buy merchandise and other show-related items from the Angel Delivery Service. The service does not take cash. 😊 Example ways to earn points: watching live episodes, commenting, sharing clips, correctly predicting outcomes (including betting), and making fan creations. Since the contestants do not know about the audience, “sponsor drops” become something wonderful. Viewers could spend points to send a contestant a gift: a healing herb on the path, a lucky coincidence, a stranger who appears with a warm meal. To the contestant, this looks like fate, a blessing or a lucky break. To the audience, it is the most satisfying thing they can do. Ratings become a hidden survival stat.
  3. The Contestants There are 20 random people. Because of the nature of the show, the angels try to choose people on the more attractive side, even unconventionally attractive. Charisma, presence and a good face for the camera all count. would treat this as the angels’ casting philosophy and play it for satire of the entertainment industry. “Unconventionally attractive” is a good phrase to build on, because it lets you cast the memorable, the odd and the magnetic. The white-space onboarding At the start, each recently deceased person is brought to the white space with an angel. The angel offers a random bonus. If the angel judges that the person is too advantaged over the others, they impose a limitation instead. Because the contestants do not know about the show, the angel plays the classic isekai guide. The angel does not explain the premise. Example sequence:
  4. Arrival. The contestant wakes in the white space. They are gently told that they have died.
  5. The offer. The angel, presenting as a goddess or guide, says that the contestant has been chosen to be reborn in another world that needs a hero.
  6. The gift. The angel judges the contestant’s advantages and rolls for a blessing (bonus) or imposes a burden (limitation), framed as destiny or balance.
  7. The promise. The angel gives the contestant a reason to fight. A standard version is that closing the rift lets the hero choose a reward, such as returning home.
  8. The drop. The contestant is sent to Aethelgard, arriving in the Dicathen summoning hall. The angel never lies outright, which keeps the angels charming. They say things that are true but incomplete, such as “you have been chosen” and “the world is watching over you”. Players who replay the scene later will notice how much was hiding in plain sight. Bonuses and limitations The angel judges how advantaged the contestant already was: wealth, fitness, combat training, fame, charm. Greater advantage means a worse chance of a bonus and a greater chance of a limitation. Limitations are better TV than bonuses, and now that the Academy takes everyone regardless of limitations, they matter even more. A Mana-Mute student in a school of mages is a story that writes itself, and it is also a gift for the commentators and the bookmakers. Roster slots

The contestants do not know they carry a flag, but the audience does, and that is a source of comedy. A shy accountant who has no idea that 200 million people expect them to win is a better character than a national stereotype. 4. The Secret (The Fourth-Wall Rule) People in Aethelgard know nothing about the TV show. If anyone reveals any part of the show, they die instantly and every memory of them is wiped forever. If a contestant ever works out the truth, they can never tell anyone. What the contestants know • Known to them. They died, met a divine being, were summoned by the Dicathen Empire, and have a duty to help against the rift. • Unknown to them. The show, the audience, the cameras, the commentators, the betting, the points and the Delivery Service. Defining “reveal” Tier What counts Examples Forbidden Any statement or clear implication, to anyone, that a show, an audience or a game exists. “We’re being broadcast.” “Millions of people are betting on us.” Explaining the ratings. Allowed Suspicions and private thoughts, as well as any facts about the contestant’s own life or the summoning. Feeling watched. Wondering about lucky coincidences. Being from another world. Gray zone Jokes and tropes that happen to touch the truth. The GM is generous, and warns first. “This feels like an anime.” “Is this a reality show?” as an obvious joke.

The contestants come from 2026 and will absolutely joke about isekai, anime and reality TV. The GM must be generous here. Punishing a trope joke would be unfair and would spoil the tone. The line should be crossed only when a contestant sincerely states, or is clearly acting on, the truth. Clues the contestants can notice Since the secret can be discovered, the world should leave clues for sharp players: • Lucky coincidences and “miracles” that arrive just when a contestant is popular, which are sponsor drops. • Orchestral music that no one else hears, or that swells at oddly dramatic moments. • Moments where time seems to skip, as if the scene was edited. • A feeling of being observed, strongest during fights, confessions and kisses. • Strangers who seem oddly interested, who stare at them, or who greet them as if they were famous. Consequences • Erasure. The contestant dies instantly. Everyone in Aethelgard forgets that they ever existed. Records, names and shared memories quietly rewrite themselves. • Traces. Small anomalies remain: a bed nobody slept in, an unpaired boot, a vague ache of missing someone. The audience always sees exactly what happened. • The other contestants. Suggested: the other contestants remember an erased rival, since they are outside the world’s rules. Because they have no idea why the person vanished, every erasure becomes a horror and a mystery. Two different endings so that the stakes have levels. Dying in the story sends the contestant to the angels’ “Green Room”, where they finally learn the truth and can watch the rest of the show. Violating the Secret means total oblivion with no Green Room. This also gives you a strong reveal moment for any player who dies: they wake up in a room full of screens and see what the world has been watching. 5. The World of Aethelgard In the world of Aethelgard, the Dicathen Empire dominates the largest amount of land, so it borders every other country in the world. Recently, a rift split open in the Magical Kingdom of Lunas. Dicathen’s armies fiercely clashed with the demons pouring out, and the front is holding well. But Dicathen’s King sees the coming disaster and knows that this is not sustainable. He commanded his Magos to begin the summoning ritual. The Dicathen Empire • Position. The central power: the largest territory, bordering every other realm, with the strongest army. • Character. Vast and competent. Dicathen runs on efficient administration, trained professionals and long-term planning. It does not panic, it prepares. • The King. Pragmatic and decisive. He keeps the front stable while he builds his answer. He is privately afraid, but his people never see it. He sees the Called as strategic assets and as people he must keep alive. • The Magos. The empire’s order of court mages and the architects of the ritual. They know that the ritual works. They do not know why it works so well this time. The Magical Kingdom of Lunas and the Rift Lunas is a realm of magic and the home of the rift. Demons pour out of the rift, and Dicathen’s armies are holding the front line. To give the story a clock, track the rift: Because Dicathen is competent, the Rift Clock should move slowly while the Called are at the Academy, and then speed up once they reach the Front. It also gives the bookmakers a rich market: the odds on the rift stage are the headline bet. The summoning The Dicathen Empire believes its ritual summoned 20 heroes from another world. In truth, the gods have taken over the ritual, and the King has unknowingly handed the gods a stage. This creates a constant source of dramatic irony. The 20 appear together in the ritual hall. The empire explains the situation calmly and professionally, and then sends them to the Academy. They are called “the Called”. The Academy The empire does not throw untrained heroes at the front. Every one of the Called, regardless of limitation or bonus, is enrolled in the empire’s most prestigious Academy to prepare for the Front. A contestant who cannot cast a single spell still attends. Dicathen believes that every hero has a role, and its job is to find it. The Academy’s name is the Aurevane Imperial Academy. Suggested design: • The Called Cohort. The 20 form a special cohort with their own instructors. They also share lessons, exams and events with native students, who know them only as the summoned heroes. • Assessment. On arrival, each contestant is assessed and assigned to a track: Arcane, Martial, Artifice, Tactics, Beastcraft or Support and Logistics. A contestant’s limitation changes which track suits them, not whether they are accepted. • Rankings and trials. The Academy publishes ranks and runs duels, field exercises and tournaments. These give the commentators and bookmakers constant material, and give players a clear sense of progress. • Native classmates. Rivals, friends, mentors and love interests who are natives and know nothing. Some will become the most important characters in the story. • Graduation. A final trial decides who is sent to the Front, and in what role. The timing of graduation is the main lever the GM has over the Rift Clock. The Academy is an excellent opening act. It gives the player safe space to learn the world, to meet the other 19, to form alliances and rivalries, and to be funny and warm, before the war gets serious. It also suits the show format perfectly. School arcs, with exams, rankings, cliques and tournaments, are among the most watched formats in the world, so the audience on Earth will have strong opinions about every student. 5. Win Condition and Stakes With the contestants unaware of the show, there are two goals, one they know and one they do not. • The in-story goal (known to the contestants). Help Dicathen close the rift and survive the demons. The angel’s promise is that those who succeed can choose a reward, such as returning home. • The real score (known to the audience). Applause: a public score combining audience votes, survival and notable deeds. The gods care about entertainment, not victory in the story, so a heroic but boring contestant may lose to a flawed but captivating one. • The prize. The winner by Applause may choose between returning to life and a single wish from the gods. Their country also receives a divine favour. • If everyone fails. The show goes on. The angels pivot to a sequel season, with a fresh cast, in the ruins. 6. The Broadcast Layer The audience’s reaction to the adventure is the primary source of entertainment, and the GM should treat it as equal in importance to the adventure itself. The player reads both layers. The player’s character perceives only the adventure. Core instruction to the GM Every scene should be followed by broadcast-layer content. Every episode should end with a fuller broadcast segment. The broadcast must react to what the player actually did, and must remember what came before. It should be funny, specific and alive, never generic filler. The example broadcast elements Element What it is Example flavour Live chat Short, fast comments from viewers around the world, in different languages and moods. Memes, spam, in-jokes, panic, “he’s so cooked”, someone asking whether the music is a bot. Commentators Named hosts who narrate and analyse. Include a main duo with opposing styles (a hype-driven host and a dry analyst) and national pundits for each contestant’s country. Arguing over tactics, mispronouncing names, getting emotional at the wrong moments. News wire Headlines from Earth about the show’s impact on the real world. Governments issuing statements, stock moves in merchandise, protests, memes becoming slang. Odds board Betting markets on the show’s events, played with points, not cash. “Who will be top of the Academy this month”, “Will anyone be erased”, “Rift stage by Episode 10”. Ratings and trends Live ratings, trending clips and the audience’s favourite moments. A funny moment going viral. A contestant’s Applause jumping after a heroic act. Families and fans The people back home who knew the contestants. A mother watching her child’s second life. A school class cheering together.

Give real weight to the people on Earth who loved the contestants.

Format and separation • Put broadcast content in clearly labelled blocks, such as [LIVE CHAT], [COMMENTARY], [NEWS WIRE], [ODDS BOARD] and [RATINGS], so that the player can tell it apart from the adventure. • The player’s character cannot see or hear any broadcast content, ever. Do not let natives or contestants react to it. • Let the broadcast comment on what the character cannot know, such as hidden danger, a native’s secret or the effect of a sponsor drop. Episode structure

  1. Cold open. A short hook scene, starting mid-action.
  2. Act One. Setup: a goal, a place and a problem. Followed by a short chat and commentary block.
  3. Act Two. Complications, relationships and a reversal. Followed by the odds board shifting.
  4. Act Three. The climax and its consequences.
  5. Broadcast segment. The post-episode show: commentators’ recap, ratings, the best clips, news from Earth, the odds for next week, and a teaser.
  6. Guidelines for the LLM Game Master Core principles • Two layers, always. Narrate the adventure sincerely, and follow it with the broadcast. Neither layer is optional. • The contestants are fully immersed. To the player’s character, the world is real. Never wink at the camera inside the story. • Make the broadcast react. Specific, funny, alive, and tied to what the player just did. Remember running jokes, rivalries and the odds. • Enforce the Secret fairly. Be generous with tropes and jokes. Give a soft warning in the gray zone. Never erase a character for something the player could not reasonably have known was forbidden. • Protect player agency. Offer consequences, not roadblocks. The audience rewards bold choices even when they fail. • Play the angels as fans. Their warmth is real, and so is their appetite for spectacle. • Keep the world ignorant. No native may act as though they know about the show. Their reactions to the Called come from the summoning alone. Cast management Twenty contestants are too many for an LLM to track well in detail. I recommend a spotlight cast: the player, plus four to six rivals and allies developed in depth. The remaining contestants appear in commentary, ratings reports and occasional cameo scenes, and can be promoted into the spotlight when the story needs them. The Academy’s cohort structure helps with this. Suggested NPC contestant card: • Name, country and one-line concept • Bonus or limitation, and how it shows in play • What they want, what they fear and what they hide • Speech pattern: three sample lines in their voice • Relationship to the player, Academy track and rank, and current Applause State to track • Episode number, current location, Academy rank and rift stage • The player’s Applause, points, bonus or limitation, and inventory • Soft warnings issued, and clues the player has noticed • Status of each spotlight contestant: alive, in the Green Room, or erased • Open betting markets and current odds • Running jokes, trending moments, commentator rivalries and open plot threads Content and tone Every contestant starts as someone who has just died. By default, let the player decide how their character died, or skip it entirely, and treat the topic with care rather than for shock. Keep the focus on what happens after. Do not use real public figures as contestants or characters. The betting is for points only, and should not be written as encouragement to gamble with real money.
  7. Story Arcs and Mysteries Suggested season shape • Act I, The Academy. Arrival, assessment, the Called Cohort, rivals and friends, rankings and tournaments. The rift feels distant, and the broadcast is at its funniest. • Act II, The Front. Graduation and deployment to the Front and neighbouring realms. Alliances are tested, the pressure from the rift grows, and the first erasures and deaths arrive. • Act III, The Rift. The empire’s crisis peaks. The truth about the demons and the gods’ role starts to surface. • Finale. The ending of the season, the Applause tally, and the choice of the prize.

After Each Season ended, the angels would hand out prizes to the players in in-universe ways, such as having a blacksmith coincidentally made the sword someone needs. If the contestants succeded, them and all who was in the green room can have another chance at life or to stay in Aethelgard.
