Create a single full-page, high-quality Japanese educational comedy manga infographic consisting of 9 numbered panels arranged as one continuous 3×3 comic page.
Overall style: high-quality modern Japanese anime illustration combined with detailed historical technical illustration and vintage educational infographic design. Clean black panel borders, expressive anime characters, detailed backgrounds, readable Japanese typography, historical roller coaster diagrams, engineering drawings, charts, arrows, labels, and humorous visual reactions. The page should feel like an official educational document produced by a quirky fictional research laboratory, while still functioning as a fun manga.
The entire page must be generated as ONE COMPLETE IMAGE, with panels 1 through 9 all visible and connected as a single composition. Do NOT generate panel 9 separately. Maintain consistent character appearance, clothing, hairstyle, facial design, proportions, and color palette throughout all panels.
Recurring characters
田波菜穂子(Tanami Naoko)
A Japanese female researcher in her 20s–30s, energetic and slightly eccentric. Brown hair tied into a ponytail, expressive brown eyes, lively facial expressions, white laboratory coat over a dark blouse and dark trousers. She frequently leans forward enthusiastically while explaining things. Her personality becomes especially excited when discussing technical subjects.
黒神真風芽(Kurogami Mafume)
A Japanese female researcher with long straight black hair, black-framed glasses, calm and serious expression, wearing a white laboratory coat over dark professional clothing. Extremely composed and rational. She often reacts to Tanami's excessive enthusiasm with a deadpan expression and sometimes uses a handheld megaphone and warning buzzer to interrupt dangerous wording.
Both characters must remain visually consistent throughout panels 2–8.
PANEL 1
Historical opening panel.
Show the date:
「1898年8月16日、ローラーコースター(ジェットコースター)『Loop the Loop』に繋がる特許が取得されました」
Show an old American patent drawing labeled:
“U.S. PATENT No. 609,164”
“E. H. PRESCOTT”
“LOOP THE LOOP”
“Patented Aug. 16, 1898”
Include a historically styled portrait of Edwin Prescott, with a 19th-century American gentleman appearance: neatly combed dark hair, large distinctive mustache, formal dark suit, white shirt, tie, serious expression.
The patent drawing should visibly depict an early loop-the-loop roller coaster structure.
Vintage parchment background, subtle paper aging, historical document atmosphere.
Panel number “1” clearly visible.
PANEL 2
Interior of the fictional 「解剖研究室」.
A sign reading:
「解剖研究室」
The laboratory should contain shelves, scientific equipment, old diagrams, anatomical study materials, and a slightly eccentric research-room atmosphere.
Tanami Naoko suddenly leans toward the viewer with an extremely bright smile and energetic expression.
Speech bubble:
「ねえ!最初の頃のローラーコースターがどんな乗り物だったか知りたくない!?」
She looks genuinely thrilled to explain.
Panel number “2”.
PANEL 3
A large whiteboard suddenly dominates the scene.
On the whiteboard, show a detailed historical technical drawing of:
“Flip Flap Railway(1895年ごろ)”
「初期のループ型ローラーコースター」
The drawing should clearly show:
near-circular loop
wooden trestle structure
railway track
vehicle
direction of travel
loop diameter approximately 18–20 m
side elevation
station
technical labels
Tanami points energetically at the diagram with one hand.
Speech bubble:
「この頃のローラーコースターってね
物凄く刺激的だったんだよ🩷」
Panel number “3”.
PANEL 4
Tanami continues explaining the Flip Flap Railway with excessive enthusiasm.
She points toward the loop diagram.
Speech bubbles:
「どれだけ刺激的だったのかというと…」
「私のお〇〇〇が潰れてしまいそうなぐらいのGが掛かって来たんだよ!」
Keep the comedic implication but avoid explicit sexual imagery. The humor comes from her exaggerated expression and Mafume's later intervention.
Show the Flip Flap Railway technical drawing prominently in the background.
Panel number “4”.
PANEL 5
Tanami becomes even more excited.
Her eyes become dreamy and exaggerated, with heart-shaped highlights. Her face is flushed, and she gestures wildly.
Speech bubble:
「もうね…なんていうの
激Gの重みが私の〇〇〇〇!」
Suddenly Mafume appears from the side holding a large golden handheld megaphone and warning buzzer.
Huge yellow comic sound-effect bubble:
「ピーーーーーーーーッッッッッッ!!」
Add dramatic red lightning marks around the warning sound.
Mafume looks completely serious and unimpressed.
Panel number “5”.
PANEL 6
Mafume calmly asks:
「……で、安全になった方も説明して貰えないんですか?」
Tanami immediately brightens up, clasping her hands together with an innocent smile and heart symbols around her.
Tanami replies:
「あっ!?私、優しい方もモチロン好きだよ!」
Mafume maintains a deadpan expression.
Panel number “6”.
PANEL 7
The whiteboard now displays a detailed technical drawing of:
“Loop the Loop(1898年・プレスコットの特許)”
The diagram should clearly show:
approximately 18 m loop diameter
wooden trestle construction
vehicle
direction of travel
smooth approach curve
smooth exit curve
side elevation
engineering annotations
Tanami enthusiastically points at the improved design.
Speech bubbles:
「もうねカタチが優しいんだよ!」
「激Gで攻めて来るのも良いけど
優しく来られるのも悪くないよね!」
Mafume appears in the corner with a completely exhausted deadpan expression.
Mafume:
「あのお…私にブザーを押させないでくれると助かるのですけど…」
Panel number “7”.
PANEL 8
Tanami continues her explanation while pointing toward the Loop the Loop diagram.
Her face becomes dreamy and euphoric again, with exaggerated heart-shaped eyes and flushed cheeks.
Speech bubbles:
「急激なGが掛からない様に進んでいくの…」
「もうね…私〇〇〇〇…」
Before she can finish, Mafume raises the golden megaphone and warning buzzer again.
Huge yellow sound effect:
「ピーーーーーーーーッッッッッッ!!」
Add red comic lightning and impact effects.
Mafume remains expressionless despite the chaos.
Panel number “8”.
PANEL 9 — LARGE TECHNICAL COMPARISON INFOGRAPHIC
The entire bottom panel should be significantly more information-dense than panels 1–8, functioning as a clean technical reference page.
Top heading:
「解剖研究室の説明がほぼ成立していないのでこちらで説明します。」
Below it, divide the infographic into two large comparison sections.
LEFT SECTION — RED THEME
Title:
“Flip Flap Railway”
「初期のループ型ローラーコースター」
Use a pale red / warm off-white background with red borders and red technical annotations.
Clearly explain:
・円に近いループ形状
・曲率変化が急激
・ループ下面で非常に大きなGが発生
・乗員への負担が大きく危険
Main technical illustration:
Show a large near-circular loop with a relatively abrupt transition from the approach track into the loop.
Add a clear annotation:
「ループ直径 約18m前後」
Add another annotation:
「ループ頂部で乗員が逆さまに!」
Add red arrows showing:
「急激なG変化!」
The track geometry should visibly look harsh and mechanically abrupt.
Below the main drawing, include a graph:
「G(加速度)の変化イメージ」
The graph should show a dramatic spike and drop, clearly indicating extreme acceleration changes.
Label the horizontal progression:
「アプローチ → ループ入口 → 上昇 → 頂部 → 下降 → ループ出口」
Use red graph line.
Add conclusion box:
「結果:スリルは強烈だが、乗員への負担が大きく安全性に課題があった。」
Include a warning symbol.
RIGHT SECTION — GREEN THEME
Title:
“Loop the Loop”
「プレスコットの特許によるループ」
Use a pale green / warm off-white background with green borders and green technical annotations.
Clearly explain:
・アプローチや離脱区間をなめらかに設計
・曲率変化を緩やかにすることでGを抑制
・Gの変化が緩和され、乗員への負担が低減
・後の安全なコースター設計の基礎に
Main technical illustration:
Show the loop with smooth transition curves entering and leaving the loop.
Add:
「ループ直径 約18〜20m」
Add annotation:
「なめらかな曲線で移行もスムーズ!」
Add:
「ループ下面でもGが緩やか!」
Use green arrows to emphasize gradual curvature changes.
Below the drawing, include:
「G(加速度)の変化イメージ」
The green graph should show a much smoother, lower, rounded acceleration curve rather than a sharp spike.
Horizontal labels:
「アプローチ → ループ入口 → 上昇 → 頂部 → 下降 → ループ出口」
Add conclusion box:
「結果:スリルを保ちながらも、安全性が大きく向上した。」
Include a green checkmark symbol.
RIGHTMOST TECHNICAL SIDEBAR
Create a narrow technical explanation column titled:
「なぜ形(曲率)が重要なのか?」
Clearly display:
「G(加速度)は速度と曲率半径で決まる」
Then the formula:
“G = v² / r”
with:
「v:速度」
「r:曲率半径」
Add the explanation:
「半径が小さいほどGは大きくなる!」
Below this, show two small comparison diagrams.
Upper diagram:
「半径が小さい(急カーブ)」
Use a sharply curved track and many red upward arrows.
Label:
「G:大きい」
Lower diagram:
「半径が大きい(ゆるやか)」
Use a gently curved track and fewer, smaller green arrows.
Label:
「G:小さい」
COMPARISON TABLE
Include a compact but highly readable table titled:
「まとめ比較」
Columns:
「項目」
「Flip Flap Railway」
「Loop the Loop」
Rows:
「ループ形状」
→ 「円に近い」 / 「なめらかな曲線」
「曲率変化」
→ 「急激」 / 「緩やか」
「Gの変化」
→ 「非常に急激」 / 「緩やか」
「安全性」
→ 「低い(危険)」 / 「高い(安全)」
「乗り心地」
→ 「激しい・圧迫感大」 / 「スムーズ・快適」
「歴史的意義」
→ 「初期の挑戦」 / 「安全設計の礎」
Use red typography for the Flip Flap Railway column and green typography for the Loop the Loop column.
BOTTOM CONCLUSION
At the bottom of panel 9, place a large rounded speech-bubble-style educational conclusion:
「つまり、ループは“丸ければいい”というものではありません。
曲線の設計こそが、スリルと安全を両立させる重要なカギなのです。」
At the lower-right corner, include a small vintage illustrated 19th-century gentleman engineer/professor holding a pointer and gesturing toward the diagrams, as if giving the final lecture.
VISUAL DESIGN REQUIREMENTS
The entire page must read naturally from panel 1 through panel 9.
Use strong visual continuity:
panels 1–8 = colorful anime comedy manga
panel 9 = highly detailed technical educational infographic
red = dangerous abrupt curvature / high G
green = smooth curvature / reduced G
warm off-white paper background
black ink outlines
subtle vintage print texture
clean technical drafting lines
historical roller coaster engineering diagrams
expressive anime facial expressions
consistent character designs
Panel 9 should NOT feel like a separate image pasted onto the page. It must look intentionally designed as the final explanatory panel of the same manga.
Make the difference between Flip Flap Railway and Loop the Loop immediately understandable even at a glance: abrupt curvature and violent G variation versus smooth curvature and controlled G variation.
High detail, polished composition, excellent typography placement, strong readability, sophisticated Japanese educational manga aesthetic, humorous but genuinely informative, professional
After creating something decent, I always remind myself, “Don't forget this isn't your own skill—it's all thanks to the model's capabilities” lol... I still haven't escaped being a total beginner who relies on everyone else's prompts. I've learned so much from all your amazing prompts. I keep my prompts open in hopes they might be somewhat useful to others too. If you have any suggestions like “This prompt would be better changed here,” please don't hesitate to let me know.
