Neo World Program

Neo World Program (新世界プログラム Shin Sekai Puroguramu), or New World Program in the original Japanese, also known as Psychotherapeutic Communication Simulator, is a program created by Lilith Choi and Daeun.

Description
The Neo World Program is a program created by 606, designed to place the user in a virtual world by synchronizing directly with the user's brain.

By mounting a device to the cranium, the program allows its subjects to experience a 'synthetic virtual world'. It can replace memories formed in the real world with information contained in the virtual world. Therefore, it's possible to undo trauma sustained in the real world through the use of the virtual world, which is why the program is also known as Hope Restoration Program.

The device is for psychotherapeutic purposes only and any other use is expressly forbidden, as abusing the device risks the total destruction of the user's personality.

Avatar
The user of the Neo World Program generates an Avatar, an existence created in the game as a copy of the user's real body. The real body of the user remains in a sleep-like state, as if they're dreaming.

The avatars are constructed from specific memories of the user; thus, their physical appearance and other traits can be very different from what the person is currently like in the real world.

How the Program Functions
Since the Neo World Program is a next-gen software containing the ultimate reality, it tricks the user's brain into thinking that it's all real as their consciousness is uploaded into the virtual world.

According to Lilith, if you are hypnotized to believe you've been burned, a burn mark will really appear - if the users' brains believe something is real, it's no different than if it actually happened. Lilith also compared this characteristic to a science experiment she had once heard about:

“''In a distant country, there was a certain experiment carried out on one of their prisoners. The prisoner was blindfolded, strapped to a bed, and had small wounds applied to his toes to drain his blood. That prisoner was left alone in the experiment room, as the sound of dripping blood echoed throughout the room. But in fact, his blood was not being drained. He was just forced to listen to the sound of dripping water, but he believed he was bleeding to death. However, in spite of that, the prisoner still died.''”

Originally, in the world created by the Neo World Program, a concept like violence never existed. However, the virus that invaded the program forced the users to kill each other.

If a player's avatar experiences "death" while believing it's real, their brain inside their actual bodies will stop functioning too. Their real body will remain in a comatose state with very little chances of waking up. If an avatar that needs to be uploaded has been deleted, there's nothing that Lilith can do.

The Observers
When activated, the Neo World Program generates one or more Observers to guide the users and carry out the pre-programmed objectives of the session. As non-player characters (NPCs), Observers are not controlled by a person; their existence was created entirely by the program, with their appearance and personality influenced by the thoughts and memories of the users.

Usami and Chiaki Nanami were the original Observers of the Neo World Program. Though they did not technically exist outside of the program, they did have real-world counterparts on which their personalities and appearances were based.

Graduation
At the end of the program, the users are given the choice to "graduate" or remain in the program. If they choose to graduate, and the Observer determines that the session's objectives were met, they will complete the Hope Restoration Program. Their avatars will be uploaded into their real bodies, forcibly erasing their past selves. However, if they do not choose Graduate, they will just to continue living their tropical life.
