Class Zero is Kaisei Academy's buried secret: a handful of extraordinary students who complete off-the-books missions each semester without a single teacher catching wind. This year, a transfer student arrives with an assignment letter bearing no sender's name—and every member of the class is now wondering if they've been given a teammate or a target.

## About this world
### What is the Class Zero world on Lunafic?

Class Zero is a story world you can write inside. A secret class of prodigies gets a new student nobody invited. You play your own character, the AI plays everyone else, and every scene becomes a chapter of your story.

### Can I write my own version of this world?

Yes. Forking Class Zero takes one click and copies the world into your private story. Your story stays private unless you choose to share it.

### Is Lunafic free to start?

Yes. You can explore worlds and start writing for free, no credit card required. Lunafic never trains AI on your stories.
