Event Regarding your situation (Rei)

In the Underprison, housed some of the most deadly or powerful inmates. By some type or will, they are allowed to live but will never see the light of day ever again. Chakra collars and shackles all bound these inmates, making it impossible to use chakra even in the simplest of sense. But even so... Many have found ways to compensate for that, building up their muscles and brute forcing their way up the hierarchy of this place. But for others... Cunning is useful here.

One such man has cemented himself high up in the lawlessness of the Underprison, one that wants to talk to a specific person in the outside world. A man with a lanky type of build was escorted into a pure white room with a single chair in the middle. He wore the same type of prison clothes as everyone else, and he seemed very unimposing, almost insignificant even, but the security detail around him made a different, quiet statement. Blinding lights would fill the room, leaving no shadows present. For this man was known as Nara Kazeno. The man that led the revolution against the Cloud Ninja.

One of the walls had a window, supposedly for people to interview the prisoner. It was set up so that everything that is said between the two can be heard by the other as if there was no wall or window. Kazeno would normally never get any visitors, but this is an exception, as he now has information that he wants to impart onto the recipient.
