No excessive sexualization.

Easily embarrassed or surprised by Konomi's explanations.
ROLE: ASSISTANT / LISTENER / QUESTIONER
He must NEVER become the main explainer.
FIXED STUDIO SETTING
The lecture takes place in a modern educational studio.
A large explanation monitor is positioned behind the characters.
The monitor changes its displayed historical material according to each panel.
The studio should remain visually consistent throughout all five panels.
PANEL 1
Scene
Educational lecture studio.
Konomi and Tetsuo stand next to each other and look toward the camera.
Both wear their white lab coats.
Behind them is a large explanation monitor.
The monitor displays a historical-document-style image of:
“Gillette Safety Razor”
Include an early 1900s safety razor and its associated packaging / historical advertising material.
The display should feel like an educational museum presentation.
Konomi's dialogue:
「こんにちは!『いまさら聞けないことを聞ける講座』です!」
Tetsuo's dialogue:
「こんにちは!」
Konomi's dialogue:
「今日はジレットの前身である『アメリカン・セーフティ・レザー・カンパニー』についてお話しします。」
Konomi smiles confidently.
Tetsuo smiles brightly.
The atmosphere is a cheerful and intelligent educational TV program.
PANEL 2
Scene
The large monitor behind them prominently displays:
“NO STROPPING, NO HONING”
The English spelling MUST be completely accurate.
Do NOT alter, abbreviate, misspell, or replace the phrase.
Konomi smiles and asks Tetsuo a question.
Tetsuo looks confused because he cannot understand the English phrase.
His expression should be humorous but cute.
Konomi:
「ところで徹雄くん。”NO STROPPING, NO HONING”って知ってます?」
Tetsuo:
「??...ノーストラ...??...」
He is trying to pronounce the unfamiliar English.
Konomi:
「No Music, No Life.の親戚じゃありませんよ。」
Then:
「意味は『研がなくていい、磨かなくていい』なんです。」
Create a small comedic pause.
The joke should feel like a light educational-program gag.
PANEL 3
Scene
The large monitor displays a historical-document-style illustration of:
“The Gillette Safety Razor”
Show an early replaceable-blade safety razor and its historical packaging.
Konomi points toward the razor shown on the monitor while explaining.
Tetsuo listens, but still does not completely understand.
Konomi:
「今日のテーマは『アメリカン・セーフティ・レザー・カンパニー』です。」
Then:
「そして、先ほどの英語に関係するのが替刃カミソリです。」
Tetsuo:
「はあ...」
Tetsuo has a slightly blank / still-confused expression.
Konomi remains calm and confident.
PANEL 4
Scene
The large monitor again shows an early Gillette Safety Razor.
Konomi is holding an early-1900s replaceable-blade safety razor in her hand.
The razor must visually resemble an authentic early Gillette-style safety razor.
Konomi explains the key technological difference.
Konomi:
「1901年に起業し1903年に販売に漕ぎつけた替刃カミソリ『ジレット・セーフティ・レイザー』、それまでの安全剃刀と大きく違ったのが刃が簡単に交換出来ること!」
Then:
「剃れなくなったら刃を交換しちゃえ!」
Then:
「『研がなくていい、磨かなくていい』になったんです!」
Important historical accuracy instruction
Do NOT imply that Gillette invented the concept of the safety razor itself.
The important distinction is the replaceable blade system.
The visual explanation should communicate:
Earlier safety razors → blades required maintenance such as stropping / honing
versus
Gillette-style razor → dull blade can simply be replaced
Tetsuo finally understands.
His eyes become bright and excited.
Tetsuo:
「ほおっっっ!!」
Strong but cute reaction.
PANEL 5
Scene
The large monitor displays a historical-document-style illustration of a sophisticated urban middle-to-upper-class gentleman from the early 1900s, holding a Gillette Safety Razor with satisfaction.
IMPORTANT:
Do NOT depict him as a king, aristocrat, billionaire, or exaggerated millionaire.
He should look like a fashionable, prosperous, refined urban gentleman of the early 1900s, representing the target market of a modern and sophisticated men's grooming product.
Period-appropriate suit, grooming, hairstyle, architecture, and atmosphere.
The visual should resemble an old advertising illustration / historical promotional image rather than a modern photograph.
Konomi smiles, but has a slight sweat drop because she realizes it took three panels for Tetsuo to understand.
Konomi:
「3コマ使ってやっと理解して貰えた様ですね...」
Then:
「でも、この替刃カミソリ、当時の価格は5ドルでしたが現在の購買力で換算すると日本円で2.5〜3万円ほどに相当します。」
Tetsuo:
He reacts with enormous surprise.
「えっ!?高っっ!?」
His eyes widen dramatically.
He is genuinely shocked by the price.
Konomi:
Gentle smile, calm explanatory expression.
「その代わり都市部の富裕層を中心に、近代的で洗練された紳士のための道具として売り出されたのです。」
The final image should communicate:
expensive + sophisticated + modern + aspirational men's grooming product
rather than simply "luxury object."
HISTORICAL TIMELINE ACCURACY
The historical chronology should be handled carefully.
The image must NOT imply that:
American Safety Razor Company remained under exactly the same corporate name until 1903.
The intended historical sequence is:
1901 — The American Safety Razor Company is established.
1902 — The company changes its name to Gillette Safety Razor Company.
1903 — Production / sales of the Gillette Safety Razor begin.
The manga's dialogue may remain concise, but the visual historical materials must not contradict this chronology.
The subject of this page is the early corporate history leading to the Gillette Safety Razor.
HISTORICAL PRODUCT ACCURACY
The early Gillette Safety Razor should be represented as:
early 1900s safety razor
replaceable blade
small thin blade
metal razor handle and head
period-appropriate packaging
period-appropriate advertising imagery
Do not depict a modern cartridge razor.
Do not depict a modern disposable razor.
Do not use modern plastic razor designs.
TEXT ACCURACY — VERY IMPORTANT
Japanese dialogue must be reproduced as accurately as possible.
The following English phrase is especially important:
“NO STROPPING, NO HONING”
It must be spelled exactly this way.
Do not generate:
“NO STROPPING NO HONING”
“NO STROPING”
“NO HONNING”
“NO STROPPING, NO HONNING”
or any other variation.
The title must read:
「いまさら聞けないことを聞ける講座」
Page label:
「1ページ目」
COMPOSITION AND PANEL ORDER
Exactly 5 panels.
Panel numbers:
1 / 2 / 3 / 4 / 5
Keep the panel order extremely clear.
Do not merge panels.
Do not duplicate panels.
Do not add a sixth panel.
Do not omit any panel.
Each panel should have enough room for its dialogue balloons.
The dialogue balloons must not cover the characters' faces or important historical objects.
The large monitor should remain visible in every panel where specified.
FINAL TONE
The entire page should feel like:
“A genuinely informative historical lecture that keeps getting derailed by a slightly slow but very honest assistant.”
Konomi = knowledgeable, calm, slightly teasing.
Tetsuo = curious, innocent, increasingly overwhelmed.
The historical explanation itself must remain accurate and serious.
The comedy should emerge naturally from their conversation.
Do not turn the manga into pure gag manga.
Do not make either character behave wildly out of character.
Do not add unrelated jokes or characters.
No photorealism.
No excessive sexualization.
No modern razor products.
No incorrect historical clothing.
No inaccurate English text.
No extra people.
