Simulated Twilight Town

The simulated Twilight Town is a world from Kingdom Hearts II.

Roxas' Story
Twilight Town (or, in more a more common sense, the virtual Twilight Town that DiZ created) is the first world in Kingdom Hearts II. Roxas lives there, with his best friends Hayner, Pence, and Olette. It was created from data based on the hearts of the residents of the real Twilight Town. This means that the virtual residents act differently from their real-world counterparts.

The boss of Twilight Town is Axel.

Sora's Story
The virtual Twilight Town wasn't visited by Sora (or even known to him) for most of the game. He enters it near the end of the game with the help of Hayner, Pence, and Olette. It holds the only known entrance to The World That Never Was.

Virtual or Reality
Though not easily caught by a player on their first time through the game, there are many notable differences between the virtual and real versions of Twilight Town. These include:
 * The Fabled Countryside only exists in the real Twilight Town. The train to it in the virtual Twilight Town leads to nowhere, and is considered a ghost train.
 * The world and battle music pieces in the virtual Twilight Town are completely different from those of the real Twilight Town. Likewise, as the Twilight Town that appears in Chain of Memories is not the real one either, it uses the same pieces as that of the virtual Twilight Town
 * Hayner, Pence, and Olette have no knowledge of Roxas' existence in the real Twilight Town, but they are his best friends in the virtual Twilight Town.
 * Setzer is the Struggle champion in the virtual Twilight Town. In the real Twilight Town, it is Seifer.
 * In the virtual Twilight Town, there is a standalone building with a candy shop. In the real Twilight Town, there is a Moogle Shop instead.
 * The stores aren't functional in the virtual Twilight Town, but are in the real Twilight Town.
 * Evident only once Sora must go to virtual Twilight Town, the computer in the virtual world's Old Mansion's basement is destroyed (by Roxas), while it is in perfect shape in the real Twilight Town.
