How to Come Up With a Manga Idea in 7 Minutes
Direct Answers
How do you come up with a manga idea by tweaking an existing story?
Take a story that already works and change one fundamental thing about it. Write down the core concept of your favorite manga, and then change a key element to make it feel fresh.
To get a concept that is familiar but unexpected, you can change these elements:
- The main character's central motivation.
- The nature of the protagonist's goal.
- The overall setting or time period.
What is the fastest way to get a high concept manga idea?
The fastest way to a high concept idea is to combine two things that should not belong together. The contrast is what creates the hook for the story.
Make a list of character archetypes or skills, and a second list of settings or genres. Combine one from each list and force yourself to write a one sentence summary of the premise.
How can you rescue a forgotten manga idea?
Find a manga or anime that is widely considered a failure. Ignore the plot and the characters to focus on the one part that shines.
Pinpoint a single element with potential, such as a power, a world rule, or a villain concept. Write a new one sentence premise using that idea, but place it in a completely different genre or give it to a different type of protagonist.
How do you borrow manga ideas from other fiction?
Go into other worlds like movies, video games, and novels to bring their best ideas back into manga. You should steal structure and mechanics instead of just looking for plot ideas.
For example, you can design a manga fight scene like a multi-phase video game boss battle. You can also map out an action scene from a movie and apply that framing to your panel layout and page flow.
Tweak an Existing Story
Before you can write the next hit manga, you need an idea. You need a concept that hooks a reader from the first page and doesn't let them go.
Nothing is truly original, and every story you love stands on the shoulders of other stories. Take a story that already works and change one fundamental thing about it to get a concept that is familiar and completely unexpected.
A perfect example of this is Kaiju No. 8 and Attack on Titan.
In both stories, humanity is on the brink and constantly attacked by giant destructive monsters.
In both, a specialized military force is the only thing standing between the monsters and total annihilation. The protagonist is a man who gains the power to turn into the very monster he's supposed to fight.
The core structure is the same, but Kaiju No. 8 made one massive change that created a brand new story. It changed the protagonist.
In Attack on Titan, Eren is a young, passionate, and angry teenager driven by revenge. In Kaiju No.
8, Kafka is a 32-year-old man who already failed to achieve his dream.
Kafka is not a hot-headed soldier. He cleans up the monster guts left behind after the battle is over.
This change transforms the entire story. The themes, character struggles, and tone are completely different, even though the basic premise is the same.
Write down the core concept of your favorite manga. Change the main character's central motivation or the nature of their goal to see a new story instantly start to form.
You can even change the setting or time period as well.
Combine Opposites
The fastest way to a high concept idea is to combine two things that should not belong together. The contrast is what creates the hook.
Many of the most memorable manga are simple, powerful mashups. A perfect example is Mashle: Magic and Muscles.
It takes a magical school like Harry Potter and combines it with a protagonist who has no magic and superhuman strength like One Punch Man. The entire story is about this clash.
How does a kid with zero magic survive in a world that values only magical talent? By punching his way through it.
The concept is simple, absurd, and works perfectly.
Another great example is Zom 100: Bucket List of the Dead, which mashes up two completely opposite genres. It combines a terrifying zombie apocalypse with an uplifting feel-good slice of life comedy.
The world is ending, which is horrible for everyone else. For the main character, a miserable office worker, the apocalypse is the first time he's ever felt free.
The story isn't about surviving zombies, but about the joy of finally living.
The real test of a mashup is the one sentence premise. If you can't explain your idea in a single compelling sentence, it might be too complicated.
Make a list of character archetypes or skills like a samurai, detective, or chef. Make a second list of settings or genres like outer space, a haunted house, or a high stakes sports tournament.
Combine one from each list and force yourself to write a one sentence summary.
Rescue a Forgotten Idea
Start reading manga that sucks. Read the manga that got cancelled after 15 chapters, or the anime that has a terrible rating online.
The graveyard of forgotten series is full of incredible ideas that were wasted by poor execution. Your job is to be an idea scavenger.
Walk through the rubble of a failed story, find the one part that shines, and pull it out to build something new and better. You are taking a brilliant concept that was trapped in a bad story and giving it a proper home.
Find a manga or anime that is widely considered a failure. Ignore the plot and characters to pinpoint a single element with potential.
Find a power, a world rule, or a villain concept that could be great. Write a new one sentence premise using that single idea, but place it in a completely different genre or give it to a different type of protagonist.
Borrow From Other Fiction
If you only ever read manga, you will only ever create manga that feels like something you've already read. The well of inspiration eventually runs dry.
Your job is to go into other worlds like movies, video games, and novels to smuggle their best ideas back into the world of manga. Don't just look for plot ideas, but steal structure and mechanics.
A great video game boss battle is a masterclass in storytelling and pacing. The boss has different phases and a changing attack pattern, which is a perfect structure for a multi-chapter manga fight.
The hero has to discover a weak point or use the environment to win. That's far more interesting than just having two characters punch each other until one falls down.
Imagine designing your next fight scene like a boss battle from a game like Elden Ring or God of War. The tension, strategy, and payoff are already built in.
Think about action movies and deconstruct how a great film director frames their shots. Apply that same thinking to your panel layout and page flow.
Your manga will feel more dynamic and cinematic than anything else out there.
Pick your favorite video game level or a single action scene from a movie, and map it out. Note the sequence of events, the core challenge, and how the tension rises and falls.
Try to sketch a one page manga scene using that exact structure as a powerful exercise.
To find your winning manga idea, you can change a core element of a story that already works or combine two opposite concepts to create a new one. You can also rescue a great idea from a bad story, or borrow from movies, video games, novels, and history.
The goal is to build a concept that makes even the author desperate to know what happens next. That's an idea worth writing.
