A medium size prison hidden somewhere in the Fire Country. So hidden, i cannot even tell you about it. Actually, we never had this conversation. Criminals are taken to this location as prisoners of war, Rouges to be transferred to their rightful villages and/or waiting to be executed. They are bound by a black hood over their faces, trapped into:
Kokuangyo no Jutsu (Bringer of Darkness Technique)
Description: An ancient technique created and mastered by the late Nidaime Hokage, it utilizes the foremost creator of fear: darkness. By creating a complete and impenetrable darkness around the user, the actual affect is not to scare them, but to disable them. Doujutsus are especially hindered by this technique because it affects the nervous system in such a way that it deactivates them. Indeed, there is very little that can pierce that jutsu, not even interference from allies. The only way to break this jutsu is by throwing the user off guard or if the user wills it.
As well as having a collar placed upon their necks:

Hidden Leaf Chakra Control Device 2.0:
This device can suck out the chakra of a captured enemy combatant, eliminating their ability to use jutsu. The new modified device would not short out when used in close proximaty to another device of the same. It is perfect for use on shinobi A-ranked and up and those with demons. It would take 5 to subbed due a higher ranking Demon 6 and up. It is shaped like a box in order to clamp onto the enemy's arms, torso, legs or head and then be locked with a key.
