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". This is that a death sentences prisoner can die at any moment, seemingly by an "accident". It is the only fully publicly operated prison in Japan.

Its original Warden in unnamed, but after he was killed by the Red Man, Tsunenaga Tamaki (previous Assistant Warden) became Warden. The Chief Guard is Makina. Deadman Wonderland was closed after its original goals and the Deadmen were exposed to the world and after the death of Tamaki. All Deadmen were released afterwards and the regular prisoners were transferred to another prison. However, the building was still used as a base by Toto Sakigami and was impossible to infiltrate by the special forces. 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.
