One Piece postcard set
Three real postcards from the page’s own generation run.













Three real postcards from the page’s own generation run.
A postcard is three things at once — a character, a place and a line — and most tools only make the first. In Studio a character is a material with a cover, a location is a material with its own light, and the card is drawn from both, so the second card of the same pair matches the first. Every card saves as a work with its own URL: send it, print it, or fork the world and keep going.
One finished postcard image: the scene drawn, a cream border with a gold rule, a handwritten line, and the place name set under it. Not a raw character portrait you still have to lay out.
Yes. Say it in your sentence — "write: see you in spring" — and it goes in the margin. Leave it out and the agent picks a six-word line that fits the scene.
Any world in Studio: an existing anime world such as Genshin Impact, One Piece, Horimiya or Demon Slayer, or your own cast. The card is drawn from the world's materials, so the faces stay the ones already in it.
If the character is a material in the world, its cover image is used as the reference. If not, attach a photo or a character sheet and the prompt tells the agent to match it. These are fan works, not official art.
One 3:2 landscape image, the shape of a 148×105 mm postcard. Export a high-resolution copy and it prints at 6×4 inches with the border intact.
Yes — attach a place or a person, describe the moment, and the card is drawn around that reference with the border and caption added on top.
Short lines come out clean because there are few letters to get wrong. Read the caption before you keep the card; if a letter slips, ask for the same card with the line rewritten and keep the good one.
No. One sentence is the input. The button opens a new world with the prompt already written for you.
A rooftop at sunset is enough to start.
