Worlds you can play now
Six worlds are ready. The art shows each world's backdrop and characters.
How each genre begins
Isekai
A goddess tells you to live as you like, and you arrive just as a black dragon closes in on the royal capital.
Romance
Your engagement has been announced without your knowledge, and five adults each keep a secret.
Spy
Eleven missing people call you for help, and a recall-order mission begins.
Idol
Your pass is revoked right before the final audition, and you aim for center stage anyway.
Life
You wake up 18 again, free to redo your life your way.
School
On your first day after transferring, three classmates talk to you after class. The welcome party is in four days.
Some of the characters
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.
Free turns and plans
Regular turns use no credits. How many turns you get per day depends on your plan.
| Status | Turns |
|---|---|
| No account | About 30 turns. Then log in to continue the same adventure |
| Free plan | Your first 40 turns (including those played before logging in), then 10 a day |
| Perch | 30 a day |
| During the free trial | 100 a day |
| Watering and higher paid plans | Up to 600 a day (fair-use limit) |
Daily turns reset at midnight Japan time. A conversation with a character counts as half a standard turn. Creating worlds is free too, with a daily limit on how many you can make.

FAQ
Which world should I start with?
Each one begins with its own opening scene. Pick whichever premise grabs you; you can switch to another world later.
Is there mystery or horror?
For anything the ready-made worlds don't cover, create your own world from one sentence.
How far does the romance go?
It focuses on how your relationships change. Worlds with high-school characters restrict romantic actions. Mature settings are available only after age verification.
Do I need to bring my own art?
No. The ready-made worlds come with backdrops and character art.
