Stage 1: The Core Idea
Logline: (Describe the story in one single, gripping sentence.)

Example: A cowardly boy discovers a magical paintbrush that brings anything he draws to life, but only if he learns to draw with confidence.

Central Theme/Question: (What is the "heart" of the story or the question you are exploring?)

Examples: Is talent born or made? What are you willing to sacrifice for your dreams? The definition of true justice.

Stage 2: Character Conception
The Protagonist (MC):

Name:

External Goal: (What do they want that everyone can see?)

Internal Need: (What emotional growth must they undergo to be happy, though they don't know it yet?)

Fatal Flaw: (The character defect that gets in their own way.)

"The Ordinary Life": (Describe their life before the story begins.)

The Antagonist/Rival:

Name:

External Goal: (Their goal must clash directly with the protagonist’s.)

Philosophy: (Why are they right in their own eyes?)

Connection: (Why this villain for this hero?)

Stage 3: The World Building
Setting: (Time period, location, rules, and aesthetic. Urban fantasy, sci-fi cyberpunk, historical feudal?)

The Magic/Power System (if applicable):

Rules: (What is possible?)

Limitations & Cost: (What is impossible? What happens if you use too much power? Limitations make power systems interesting.)

Stage 4: Structure (The Arc)
The Inciting Incident: (The event that shatters the protagonist’s ordinary life and pulls them into the conflict.)

The Journey (Rising Action): (The challenges, new allies, and rivals they meet. They fail and learn.)

The Low Point: (The protagonist loses everything and must confront their internal need.)

The Climax: (The final showdown where the protagonist uses their newfound strength to face the ultimate challenge.)

The Resolution: (The new normalcy.)

Four Example Manga Story Ideas
Use these as inspiration, or build your own from the prompts within.

Idea #1: Supernatural Mystery / Action (Shonen-Style)
Logline: To save his sick sister, a cautious student contracts with the demon of forgotten names, gaining powers tied to the things he can remember to say.

Genre: Action, Dark Fantasy, Supernatural.

Central Theme: The value of memories and what defines an identity.

Magic System: Contract Memory. Powers are strong only when the user remembers the specific name or incantation. Forget the name, and the power vanishes.

Conflict: He must hunt other demons for artifacts that can cure his sister, but the more he hunts, the more people and history are erased from the world.

Idea #2: Psychological / Thriller (Seinen-Style)
Logline: An expert archivist finds a hidden section in the world's oldest library: the "Future Files"—detailed biographies of people that haven't been born yet.

Genre: Psychological, Thriller, Science-Fiction.

Central Theme: Determinism vs. Free Will. Can we change the future if we know it?

Conflict: The protagonist starts subtly manipulating events to prevent disasters (like a benevolent "Death Note"), only to discover that the Future Files are actively adapting and predicting his interventions, escalating the stakes.

Idea #3: Slice-of-Life / Drama (Josei/Seinen-Style)
Logline: A burnt-out urban planner moves back to her quiet coastal hometown and discovers a unique "Café of Lost Recipes," where she helps people recreate meals that connected them to loved ones they've lost.

Genre: Slice-of-Life, Comfort, Food/Cooking.

Central Theme: Grief, reconnection, and finding joy in small moments.

Conflict: Her internal battle against feeling like a "failure" for leaving the city. The conflict comes from the emotionally complex requests—like a daughter asking for the simple rice ball her abusive father once made her.

Idea #4: High-Stakes Sport / Competitive (Shonen/Shojo-Style)
Logline: A naturally talented but unmotivated pianist must partner with a classical prodigy who plays with flawless technicality but no emotion to win a national ensemble competition and keep his family’s music school from closing.

Genre: Sports (Music), Drama, Competitive.

Central Theme: Technical mastery vs. emotional expression; finding synergy with a rival.

Conflict: The duo's conflicting philosophies clash at every practice. They must learn not just how to play "together," but how to breathe and feel as one musical entity to win.
