Deadman Wonderland (Prison)

Deadman Wonderland, often abbreviated to DW, is a privately-run prison in Tokyo that doubles as an amusement park. It was supposedly built for the revival of Tokyo, pulling a lot of tourists to the prison's special attractions. In reality, it is a place to hold Deadmen, and in particular, to seal the Wretched Egg. The prison is built on the Mother Goose System. It has 6 normal wards (labelled A-F) and 1 Deadmen-ward (G Ward). The prison has a special system called the "death sentence rule". That is that every prisoner on death row has a modified necklace, one that constantly injects poison. The only way to escape death is to eat Candy every three days. However, Candy costs a lot of CP. DW is the only fully publicly operated prison in Japan.

History
DW was built after the Great Tokyo Earthquake with an unnamed Warden in control. The warden was in fact sick, and it was the Assistant Warden who was pulling the trings. For ten years long, DW sought Deadmen and imprisoned them. The Carnival Corpse was also one of the first events in DW. The original Warden died and Tamaki finally became Warden. In the year 2024, Scar Chain attempted a prison break, but it failed. They tried again and succeeded, but only Karako Koshio and a handful henchmen escaped. Karako revealed DW's secrets to the media, but Tamaki depicted these Deadmen as animals and inhuman, so now even the Carnival Corpse was broadcasted. Around this time, the Forgeries were also introduced. But then the Chief Guard Makina discovered Tamaki's plan and did a coup d'état. She succeeded with the help of Ganta Igarashi and the other Deadmen. But then Toto Sakigami appears and takes DW for his own. Tamaki was killed and DW was closed for good. All Deadmen were released afterwards and the regular prisoners were transferred to another prison.

Makina has set up a mission to infiltrate DW and to use the Mother Goose System to completely seal the Red Man. This mission is still ongoing.
