Sepia Hamster Summer Homework Manga Prompt

Goal: Create a vertical monochrome Japanese manga page about a true-story style hamster father going overboard with a child’s summer homework poster.

Canvas: Tall portrait manga page, about 9:16, sepia ink on warm off-white paper, hand-drawn crosshatching and pencil-like linework, thin black panel borders, nostalgic Showa-era storybook atmosphere.

Layout: Use exactly 6 stacked horizontal comic panels. Interior setting is a cozy wooden room with floorboards, bookshelf, potted plant, curtains and window, art supplies, a large sheet of drawing paper, paint tray, bucket, brushes, and mugs. Keep all dialogue in Japanese speech bubbles and narration boxes.

Characters: Two fluffy hamsters. The child hamster is small, round, cute, black glossy eyes, no glasses, drawing earnestly with a brush. The father hamster is larger and rounder, wearing small round glasses, holding a mug at first, then a brush, becoming increasingly intense and focused. Both are rendered as realistic-cute hamsters rather than humanoid mascots.

Panel details: Panel 1 shows the child hamster facing a blank poster sheet on the floor, art supplies on the left, curtains and bookshelf behind. Add a vertical narration box on the right reading 「ハムスターの夏休みの宿題は『自由研究』の課題ポスターの提出が必要だった」 and a speech bubble from the child reading 「今年も緑化ポスターを描こう」. Panel 2 shows the child hamster drawing trees on the large paper while the father hamster with round glasses stands nearby holding a mug and watching. Panel 3 shows father and child side by side over the poster; father points or comments with a bubble 「ポスターか」 and the child replies 「うん、夏休みの宿題」. Panel 4 shows the father asking to borrow the brush, facing the child across the paper; include a question mark over the child’s head, father bubble 「ちょっと貸して」 and child bubble 「うん？」. Panel 5 is a close-up of the poster becoming extremely detailed: dense forest scenery with many trees and foliage, father’s paw holding a brush at the upper right, child bubble on the left 「おお……！お父さん上手！」. Panel 6 shows the father hamster completely absorbed, sweating and hunched over the poster, drawing an incredibly elaborate forest with dramatic speed lines; the child hamster behind him looks shocked and panicked. Include scattered art supplies, paint tray and bucket. Add a jagged speech bubble from the child reading 「お父さん……!!そしたらハムスターが描いたポスターじゃなくなっちゃう!!!お父さん!!お父さん!!」 and a bottom caption box reading 「ラストの２日で描き直した」.

Visual style: Vintage Japanese newspaper manga, soft sepia monochrome, detailed fur texture, expressive faces, gentle comedy pacing, realistic room perspective, no modern digital coloring, no watermark.
