Real BunCho Play screens (captured October 30, 2026)
How one turn plays
Every screen here is the real BunCho Play, played in the isekai world without logging in.
-
Pick a world, or write one sentence
Choose a ready-made world, or describe the world you want in one line under “What kind of world do you want to play in?”
-
The first scene opens
The game master (GM) sets the scene and characters speak to you. Three suggested actions appear as A, B and C.
-
Act in your own words
Tap a suggestion, or type whatever you want to do. Actions that aren't on the list work too.
-
The GM tells you what happens
The GM narrates the result, characters react and what you've learned is updated. The next suggestions change with it.
What you can do in BunCho Play
Tap a choice or type freely
Advance with the A, B and C suggestions, or write any action you come up with.
Create a world from one sentence
From a line like “I miss the last train, and a train from a line I've never heard of pulls in,” the setting, hero, characters and goal are generated.
A log that sticks
Facts you've learned, promises, items and each character's trust are recorded and used in later narration.
Runs in your browser
Play on a phone or a computer with nothing to install.
It remembers what happened
Your adventure log sits beside the story and feeds the next turn's narration. Below: the screen after two turns.
- What you know: each fact is kept with where you learned it
- People: trust and closeness change with what you do
- Promises, items and techniques: decisions and things you picked up stay on record
- Autosave: stop any time and pick up where you left off
Worlds you can play now
Six worlds are ready. The art shows each world's backdrop and characters.
Some of the characters
Make your own world from one sentence
