The Seventh Agency

The Seventh Agency (七號機関) is a criminal group created by the government, responsible for hiding scandals, political crimes cover-ups, illegal tactics, and many more things that regular government workers would not normally comprise.

Record of a Jailbreak
The Seventh Agency was first mentioned by Mushitaro Oguri, which in his account is the organization that held responsible for his captive, exploiting his special ability to help erase evidence of their crimes.

Upon a questioning by Oguri, Ango Sakaguchi confessed about employing the organization, albeit only once to help erase Osamu Dazai's past crimes to atone for the death of his friend, Sakunosuke Oda.
