An anime plot generator writes a series pitch with the beats a seasonal show is judged on: who wants something, what blocks them, what the picture keeps showing, where episode 1 starts, and what the cour builds toward. This page holds 33 original pitches. Working titles such as Receipts of the Other World, Appeal Before the Bad End, and Last Bath of the Day name the seeds. They are not existing series.
Filters cover 12 settings (Isekai, School, Shonen / battle, Mecha, Slice of life, Sports, Magical girl / fantasy, Horror, Sci-fi, Romance, Mystery, Idol / showbiz), 6 tones (Comedic, Dramatic, Dark, Wholesome, Romantic, Mystery), and 3 pacing modes. A seed matches one setting, one tone, and one pacing. When your three filters have no seed, the tool says so and opens a wider pool. The output is a brief you can copy into a treatment, a manga one-shot plan, or a web serial. It is not a finished script.
Three steps from a filter to a logline someone else can repeat.
Pick one of 12 settings, a tone, and a pacing. Read the match line. If it says there is no exact seed, you are looking at a wider pool and the note names which filter was relaxed.
Generate a pitch and read only the episode-1 cold open. If you would not stay for the theme song, generate another seed or rewrite the lead before you outline the cour.
One sentence: who wants what, and what blocks them. Leave the twist out of that sentence. Then name three comps — one classic anime, one recent title, and one from another medium.
The same fields every time, so two seeds are easy to compare.
A name for the seed, such as Sponsored Duels or Salt on the Setlist. It is a label for your notes, and you can replace it.
Who the series follows, what they want, and the obstacle in the same breath. That trio is the logline before the twist.
Objects that can repeat in the storyboard, the end card, and the key art: receipts, chalk lines, cedar bath lids, ticket gates.
The turn that redefines the premise. Keep it out of episode 1's first minute so the cold open stands alone.
A pre-credits image written like a broadcast hook, not a neutral synopsis.
A season peak, plus a reminder about comps, cour length, or the logline test.
Original working titles in the same pool the generator draws from. The full lead, twist, cold open, and climax appear when you generate.

Terms the filters use, with the seed titles that belong to them.
A cour (クール, from the French cours) is a Japanese television season of about three months. A one-cour anime is usually 12 or 13 episodes. Two cours back to back are roughly 24 to 26 episodes. A split-cour airs one cour, pauses for a season or more, then returns for another cour of the same story.
The scene before the opening credits. In seasonal anime it is often the first proof that the premise can hold an episode. Every seed on this page includes one.
One sentence a stranger can repeat: who wants what, and what is in the way. Write it from the lead and the setup. Add the twist in a second sentence.
異世界, 'different world.' The protagonist is summoned, reincarnated, or pulled through a portal. The boom in the 2010s ran through web novels on Shōsetsuka ni Narō, then light novels, manga, and anime. Examples people cite include Re:Zero and That Time I Got Reincarnated as a Slime. Seeds here include Receipts of the Other World, Field Hospital, and Soil Before the Crown.
A fantasy character arrives in the contemporary world, instead of a modern person leaving it. The Knight and the Yamanote is that shape: a knight comes through a station lost-and-found into Tokyo. It sits under the Isekai filter.
A reincarnation into the antagonist of an otome game, usually with a scripted condemnation or bad end to dodge. My Next Life as a Villainess is the comedy people name first. Appeal Before the Bad End is this tool's version: a contracts lawyer has three days to appeal the condemnation, and the heroine is also a reincarnator.
Demographic labels for manga magazines. Shonen targets teen boys; Weekly Shonen Jump is the best-known magazine. Seinen targets young adult men and more often allows slower or harsher stories. Shojo targets teen girls, and josei targets adult women. This generator's battle filter is a tournament shape, not a demographic assignment.
Mahō shōjo: a transforming hero, often with a mascot, a contract, and a finishing move. Sailor Moon (1992) is the global reference for the bright version. Puella Magi Madoka Magica (2011) is the title people cite for a darker contract. The Tired Wand is this pool's comedy. The Debt Transformation is the one where the power source is collective guilt.
Giant-robot anime. Fans split super robot stories (a unique hero machine, hot-blooded fights) from real robot stories (military hardware, pilots, and politics), a line associated with Mobile Suit Gundam (1979). Soup in the Hangar is a found-family hangar story. The Mech That Breathes is a defense-contract story.
Slice of life follows ordinary days. Iyashikei ('healing') is the low-conflict comfort subset, associated with shows such as Laid-Back Camp, Aria, and Non Non Biyori. Last Bath of the Day is the iyashikei seed: an onsen attendant refuses a travel show that wants a ghost. Other slice seeds, such as Four Minutes of Foam, carry a mystery.
Stories about performers, auditions, and fans. School-idol franchises such as Love Live!, production franchises such as The Idolmaster, and industry dramas such as Oshi no Ko occupy different corners. Salt on the Setlist is a port-town unit. Zero on the Countdown is a backup dancer promoted when the center vanishes on stream.
A pacing mode, not a genre. Each episode adds a wrong detail and withholds a central answer. The phrase is associated with J.J. Abrams's description of a locked box the audience wants opened. Here it fits seeds such as Tapes That Do Not Exist, One Detail Wrong, and Scores for Feelings.
A Japanese illustrated novel aimed largely at teens and young adults. A common 2010s path was web novel, then light novel, then manga, then anime. A pitch from this tool can start at any of those steps. It does not have to pretend it is already on a broadcast schedule.
Neighboring labels get collapsed in roundups. This is how the seeds on this page split them.
| Pair | First shape | Second shape |
|---|---|---|
| Isekai and Reverse isekai | Isekai. A modern person is taken to another world, as in Field Hospital or Soil Before the Crown. | Reverse isekai. A fantasy person arrives in our world, as in The Knight and the Yamanote. |
| Shonen battle and Darker war story | Shonen battle. A tournament or televised duel with a power that has a rule, as in Sponsored Duels and Page Seven. | Darker war story. The fight is about the story people are told afterward, as in After the Parade. |
| Bright magical girl and Dark contract | Bright magical girl. A long transformation, a tired mascot, and a monster that looks like homework: The Tired Wand. | Dark contract. Power that bills someone else, and a mascot who profits: The Debt Transformation. |
| Slice of life and Iyashikei | Slice of life. Ordinary work that can still hide a secret, as in Four Minutes of Foam. | Iyashikei. Comfort is the point, and outside drama is turned away: Last Bath of the Day. |
| Idol and Sports | Idol. The performance and the fandom are the arena: Zero on the Countdown, Salt on the Setlist. | Sports. The match is the arena, and the crowd can be the obstacle: The Empty Stands, A Tie on the Podium. |
| One cour and Two cours or a split-cour | One cour. About 12 episodes. The climax has to be earned by episode 11 or 12. | Two cours or a split-cour. About twice the episodes if they air together, or a second cour after a pause. Leave a door only if you mean to return. |
A cour is about three months of television, usually 12 or 13 episodes. Four moves turn a generated pitch into that length.
Open on the seed's cold open, then state the want before the credits. The viewer should know the genre promise: a duel, a delivery route, a song, a contract.
A one-cour show has about 12 episodes. The early episodes should be satisfying examples of the genre, not only clues. A sports pitch needs matches. An idol pitch needs performances.
Put a half-reveal near the middle. The full twist can wait, and the episode still has to work for someone who guessed it from the cold open.
Use the climax field as the season peak. If you want a second cour, leave one open door. If this is the whole story, close the want. A split-cour pause belongs between those shapes, not in the middle of the climax.
The Story Plot Generator writes beats that can sit in a novel or a general script. This page writes the broadcast brief: cold open, motif, and a climax sized to a cour, inside settings such as isekai, mecha, and idol. The Writing Prompt Generator stops at one scene. The Trope Generator is useful after the pitch is chosen, when you want a named trope on top of a setting you already like.
A practical order is pitch, then logline, then a 12-episode card, then key art from the Art Prompt Generator using the motif line.
What the generator on this page actually contains.
Each seed has a working title, from Receipts of the Other World to Last Bath of the Day.
