Eight-Panel Train Delay Manga

Goal: Create a gritty black-and-white seinen manga page about {argument name="protagonist" default="an exhausted middle-aged Japanese commuter"} having a breakdown over train delays and online criticism. The tone is intense, satirical, claustrophobic, and horror-like, with dense crosshatching, heavy ink shadows, sweat, trembling hands, distorted facial expressions, speed lines, and dramatic manga sound effects.

Canvas: Vertical manga page, roughly A4 proportions, monochrome only, divided into exactly 8 numbered panels with thick black gutters. Each panel has a small white square panel number in the upper-left corner: 1, 2, 3, 4, 5, 6, 7, 8.

Visual style: Highly detailed realistic Japanese manga, similar to dark social satire manga; extreme close-ups, wrinkled skin, visible pores, bulging eyes, sweat beads, messy black hair, cheap suit and tie, crowded urban textures, station signage, phones, bookshelves, posters, and chaotic ink hatching. Use Japanese manga speech balloons and caption boxes. Make the lettering look hand-drawn and printed in Japanese.

Panel layout and content: 
1. Wide top panel across the page. A packed commuter train station platform in the morning, dense crowd in suits, overhead beams and signs. In the center foreground, the protagonist stares down at his smartphone, hollow-eyed and exhausted. A large digital station board reads 「中央線（快速）」 and shows 「遅延 25分」, with smaller destination/service text. Include two speech balloons: 「また朝から遅延…。」 and 「中央線、また止まってる…毎日これじゃ困るんだよ…」.
2. Medium panel, close-up of his smartphone screen while he posts to social media. The interface resembles a Japanese posting screen with time 07:42, a button 「ポストする」, and typed text: 「また遅延。日本の鉄道って言うほど便利か？」. His fingers grip the phone tensely.
3. Medium panel in a cramped room or shop-like interior full of train books, posters, timetables, and railway memorabilia. The protagonist, now wearing glasses, glares at his phone with sudden anger and recognition. Speech balloon: 「……来た。」. Background includes small Japanese labels about railway analysis and timetables.
4. Narrow dramatic close-up panel of one eye behind cracked-looking glasses, veins visible, sweat pouring down. Use lightning-like cracks and aggressive texture. Overlay four bold Japanese phrases around the eye: 「安全確認」, 「相互直通」, 「乗務員運用」, 「ダイヤ乱れ」.
5. Medium panel, extreme frontal close-up of the protagonist screaming in rage, mouth open with crooked teeth, sweat and spit flying, vertical speed lines behind him. Speech balloons: 「事情も知らずに…！」 and 「遅れるのは理由がある！だから仕方ないんだ！」.
6. Medium panel, close-up of both hands furiously typing on a phone, fingers distorted and tense. Large manga sound effect above: 「カタカタカタカタ」. On the screen, show a hostile reply being typed: 「事業者の努力も知らずに文句を言うな 国交省目線で考えろ」 with a small 「返信」 button and Japanese kana keyboard visible.
7. Medium panel, the protagonist lunges toward the viewer pointing accusingly, face grotesque with rage, city street or station buildings behind him. Multiple speech balloons: 「お前みたいなのが現場を分かってない！」, 「素人は黙ってろ！」, and 「安全軽視か？」.
8. Large bottom panel spanning the width. The protagonist sits shocked and pale, holding his phone, as a swarm of online reply bubbles attacks him from the right side where a monstrous angry face/hand looms in chaotic ink. Big white sound effects 「ワラ」 repeat in the background. His speech balloon: 「ただ困るって言っただけなのに…。」 Include exactly 8 visible online reply bubbles around the phone/monster, labeled with short Japanese comments: 1 「基礎から勉強しろｗ」, 2 「鉄道なめすぎｗ」, 3 「国交省の資料読んでから物言え」, 4 「勉サーノート」, 5 「もっと現場を敬えよ」, 6 「無知乙」, 7 「黙れカス」, 8 「お前が悪い」. At the bottom right, place a clean white rectangular moral caption: 「鉄道を愛することと、利用者を黙らせることは違う。」

Constraints: Use exactly 8 panels and exactly 8 reply bubbles in the final panel. Keep the image entirely black-and-white manga with no color. Preserve the Japanese text exactly where specified. Make the protagonist visibly the same person throughout: messy black hair, gaunt face, tired eyes, suit jacket, shirt, tie, and later rectangular glasses. Avoid adding extra panels, extra characters as focal heroes, watermarks, or English text.
