EnemyCity

EnemyCity is a dysfunctional city that was created by LuckyTaaru and Mr. Oof back in Elementary School. It still technically exists, just in the back of their minds. Its antonym is FriendCity. It inhabits ficitional characters that were considered "enemies" and it was a terrible place, for they believed most of those characters deserved suffering. Its most known inhabitant is Vicky from The Fairly Odd Parents. Most of the enemies have been "released" due to how silly the idea was. However, characters like Haiji Towa (who was supposed to be with the Danganronpa tuppers, but wasn't) still exist in it. 
The city is famous for the "Torture Machine", a machine where you could stuff an enemy inside it and it places them on conveyor belts to showcase many torturous methods, including watching cringey videos (like PNGTubers, which didn't exist back then, but is now used as a method, unless the person likes that content).
The city was intentionally a horrid place as a city, having poor water supply, crumbling buildings, and a poor economy. This was to maximize the suffering of the enemies, but now it functions as a proper city (or erm, prison), providing atleast basic needs for most of the enemies, such as clean food and water.
