The Vendicare Water Prison, located in Europe, suspends those contained in the lowest sections of the prison in water, making the contained person completely immobile; as such, all their muscle mass is removed and it is said that no sound nor light can ever reach those who are imprisoned here. This is possibly to prevent escape. However, Mukuro has shown the ability to use Illusions even inside his cell, and Daemon Spade was able to escape when he possessed Mukuro's body.
