Freezing Hell (極寒地獄 Gokkan Jigoku?, Frozen Hell in the Viz Manga) is the fifth level of Impel Down in which prisoners are kept. This is the level where criminals with bounties of 100,000,000 and over are kept. In stark contrast to the level above it, the entire level here is a giant freezer. The level is so cold that not only do the prisoners kept here either freeze to death or lose pieces of their flesh from severe frostbite, but the food given to them is frozen to the level of being virtually inedible. Due to the extreme cold, Den Den Mushi don't function in this Level, thus cutting off both contact and surveillance, except on the locations localized around the entrances that connects Level 5 to the previous and next levels. Along with the severe cold, the level is inhabited by wolves. These wolves roam around the level like the beasts of Level 2, where they were originally stationed at. However, they proved to be too brutal to be in Level 2 as they also hunted the other beasts as well, including the Basilisk and the Sphinx.
Along with the bitter cold of the level, there seems to be a occurrence of prisoners mysteriously disappearing as well. Prisoners who are incapable of moving by themselves have been disappearing without a trace. Because of this, the Impel Down staff and the prisoners call this phenomenon, the "demoning away". The superstition is that the missing prisoners have been actually pulled away by demons to the Gates of Hell itself. The belief of this superstition has been carefully kept within level 5 so that no inmates from the upper levels were aware about it prior to Bentham (disguised as Hannyabal), Buggy, and Galdino descending down to it where they were informed by the guards. Among these missing prisoners is Emporio Ivankov, the queen of the okama. He was imprisoned here until he mysteriously disappeared from his cell. Since then, he was rumored to be living in an abandoned guard's office deep within a forest situated in the level.
Luffy was transferred into the central tower of this floor after his loss against Magellan, until released by Bentham, hoping to find a cure.
