要点

4つの展開とキャラクター設定を決めてから各コマを制作し、吹き出しと文字は編集ツールで仕上げます。

'Gemini comic' is an ambiguous search phrase—it also refers to comic-book shipping companies. This tutorial is specifically about Google Gemini and its image models, including the Nano Banana family, for original comic storytelling.

モデルの機能に関する重要事項 Gemini and Nano Banana are Google products. This is an independent workflow guide, not Google's comic app and not a claim that every model is available inside LlamaGen.

Visual planning · original example

Four-panel story structure

This schematic is a storyboard brief, not imagery generated by Gemini. Each frame has a narrative beat, camera direction and editable dialogue. Use the same character sheet when creating actual art.

  1. Panel 01Setup

    Wide shot

    A shy copper robot enters a greenhouse in a yellow apron.

    Gardener: “Want to help?”
  2. Panel 02Mistake

    Medium shot

    The robot carefully waters an old boot instead of a planter.

    Robot: “This one?”
  3. Panel 03Reaction

    Close-up

    A tiny green sprout pushes through the boot; everyone looks surprised.

    Gardener: “Wait…”
  4. Panel 04Payoff

    Wide shot

    The boot is displayed as the garden's most unusual success.

    Robot: “I invented a planter!”

Layout diagram only. No claims about Gemini's rendering accuracy, panel count or text legibility.

Four-panel storyboard example: the robot gardener

An original story prototype ready to adapt. These are scripted panel directions, not Gemini output images. Generate or draw each beat, then letter in an editor.

Panel01 · Setup
What the reader seesWide view: copper robot enters a greenhouse, yellow apron visible.
Dialogue / editorial noteFriend: 'Want to help?'
Panel02 · Mistake
What the reader seesMedium view: robot carefully waters an old boot.
Dialogue / editorial noteKeep a clear balloon zone above frame.
Panel03 · Reaction
What the reader seesClose shot: gardener notices a sprout inside the boot.
Dialogue / editorial noteDo not swap apron or eye colors.
Panel04 · Payoff
What the reader seesWide view: boot becomes the greenhouse's prize plant.
Dialogue / editorial noteRobot: 'New planter invented!'

Keep the same character reference across panels; set the reading direction before page assembly.

手順ガイド

Follow the sequence using an original or authorized project. The workshop above is an editorial plan, not output falsely attributed to a model.

  1. Step 1

    Outline four beats

    Write setup, complication, turn and punchline in one sentence each. Limit the cast to two characters for a first test.

  2. Step 2

    Create a character bible

    Fix hair, clothing, silhouette, age and palette. Refer to your original reference artwork in each panel prompt.

  3. Step 3

    Render panels intentionally

    Choose portrait or square panels based on your story. Render separately when text, layout or composition is unreliable; do not assume a single image will preserve every panel.

  4. Step 4

    Letter after the visual pass

    Keep dialogue in a script and add balloons in a comic editor when exact text and reading order matter.

  5. Step 5

    Inspect page continuity

    Check left-to-right or right-to-left order, panels that accidentally merge, character drift, and dialogue that overlaps faces.

コピーして使えるプロンプト

Replace placeholder details with your own original story and reference assets. Paste into a compatible model or workflow; available tools and results differ.

1. Original four-panel comic

Create a family-friendly four-panel comic about a shy robot joining a gardening club. Fixed character: round copper robot, teal eye lights, striped yellow apron. Panel 1: invitation outside greenhouse, wide shot. Panel 2: robot accidentally waters a boot, medium shot. Panel 3: friends laugh kindly, close-up. Panel 4: sprouts appear in boot, playful punchline. Keep character appearance identical; no logos or copyrighted characters.

2. Panel-level art prompt

Panel 2 of 4. The copper robot with teal eye lights and a striped yellow apron tilts a watering can into an old boot. Greenhouse shelves in background; comedic pause, clean comic inking, blank room for a speech balloon at top right. Do not add any text in the image.

漫画制作で起こる問題と解決策

Specific failure patterns matter more than a generic 'try again'. These fixes target the output you can inspect.

1. Three panels look right but the fourth changes cast

考えられる原因 No stable character reference was passed.

対処方法 Keep a locked character sheet and rerender the wrong panel.

2. AI draws balloons with misspelled words

考えられる原因 Image lettering is hard to correct.

対処方法 Leave room for balloons and use editable typesetting.

3. The page feels like four unrelated images

考えられる原因 Beats lack story progression and camera variation.

対処方法 Outline setup, complication, reaction and payoff before generating.

よくある質問

Does Gemini make complete comic books automatically?

Gemini image tools can help create panels and visual stories, but page sequencing, consistent lettering and long-form continuity usually need editorial review.

Why use a dedicated comic editor?

Page assembly, speech bubbles, panel cropping and consistent characters are easier to review independently from image generation.

Does 'Gemini comic' always mean Google Gemini?

No. Search suggestions include unrelated comic shipping suppliers; add AI or Google to clarify your intent.
