Neo World Program (Danganronpa 2)

Neo World Program, or its other name Hope Restoration Program is a program created by the Future Foundation, featured in Danganronpa 2: Goodbye Despair.

The Basic
Neo World Program Is a program created by the Future Foundation that programmed to place the user in a virtual world by synchronizing directly with the user's brain.

The user in the game world called as Avatar, an existence created in the game as a copy of the user;s real body. The students' avatars were constructed by removing the school memories from the students; bodies in the real world. Which means the students' avatars were created from their memories from before they entered the academy. The body of the student still exist in the real world. But now, the students is completely submerged in the game world, as if they're dreaming.

Avatar
As example, Hiyoko Saionji more like an adult in a newspaper clipping. Since the students were avatars right now, they look exactly as they did before they entered the school. But in the real world, they've already lived out their school lives. Which means they've grown that much older, and among them, some aged so much they didn't recognize themselves.

Even the students only had memory loss, their bodies still should've grown during that time. So they should've felt their bodies go through growth spurts, but they didn't recognize each other. It's because they did not know each other before they lost their memories. If they all met after they lost their school memories, it's no different than meeting each other for the first time. Since they didn't know each other before that, they wouldn’t have noticed how much they've all grown. As Monokuma said, their memories probably erased for two or three years.

How the Program Works
Monokuma said that Neo World Program were like "you guys were hypnotized to believe you've been burned, a burn mark will really appear". So if their brains believe something is real, it's no different than it's actually happened. Furthermore, Sonia explained the same method she ever heard:

“''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.''”

The students were sleeping and connected to machines and stuff, and their consciousness was uploaded into the virtual world. So they genuinely believed that the game world was real. Actually, Jabberwock Island was a virtual environment created by the program. It looks real because the students' brains think it’s real.

The Original
The Neo World Program isn't just any game, it's next-gen software containing the ultimate reality. If a player's avatar experiences death, their brains inside their actual bodies will stop functioning too. It’s not like their bodies are completely dead, so it can't be say it's a true death. If an avatar that needs to be uploaded has been deleted, there's nothing that the Future Foundation can do.

Originally, in the world created by the Neo World Program, a concept like violence never existed. The virus that invaded this program is forcing the students to kill each other.

The Observer
Monomi/Usami and Chiaki Nanami was the observers of the Neo World Program. They were a Non-player character (NPC), a character that's not controlled by a person that was assigned the role of Observers. Monomi and Chiaki's existence was created entirely by the program, just to monitor the fifteen of the students. They didn't actually exist in the real life. That's why the Neo World Program created. The students' habitation inside the Neo World Program was just a simulation. If the Future Foundation removed the memories of Ultimate Despair time at Hope's Peak Academy, it would aslo remove their Ultimate Despair. The test is success even though it deviated greatly from the original plan of graduating after gathering the Hope Fragments.

Graduation
The students must choose “graduate”. If they choose to graduate, and the Observer determines that there are no problems, they will complete the Hope Restoration Program and their Avatars will be uploaded into their real bodies. It means by uploading their avatar's memories into their bodies, they're also forcibly erasing their past selves. That's why it's called as the Hope Restoration Project.

If the students choose “Graduate”, it'll transfer their in-game memories but their school memories will be gone forever. The people who have already died will not be able to wake up.

However, If they not choose Graduate, they'll just have to continue living their tropical life.
