The third level of the terrifying prison located in the Black Star Village, this detention place is the most fearsome of all and many people who thought of commiting crimes have been quickly brainwashed not to do so by their own mind because of the fear of the great Black Star Detention Unit.
Here prisoners are trapped unable to use chakra like the rest of the levels of the detention unit using black star metal chains enchanted with chakra-supressing seals and chakra-supressing mechanism brought from the Snow Village from the far North.
Starvation Hell (飢餓地獄, Kiga Jigoku?) is the third level of the Black Star Detention Unit in which prisoners are kept. On this level, prisoners feel the heat rising up from Level 4 and are given precious little food and water to keep them in a near death state. They are reduced to the point where merely looking at them cannot tell that they were anywhere near once frightening criminals. And while the temperature here is nothing compared to the following level below, it is intense enough to cause overwhelming dryness, resulting in Level 3's somewhat desert-like terrain.
In the middle of the level is a large hole going directly to Level 4 down below. This combined with a gigantic fan directly above the hole, serves as the main ventilation system to redirect the smoke produced from below. Level 4 can be reached through this hole, however, to travel down it holds a risk of death or scalding by the fire and heat of the floor below
