Okuni's Mansion was the home of Okuni. The mansion served as the headquarters of the Shadow Organization's Records Office (of which Okuni had authority over as the Special Adviser), and contained the archives, which dated back to organization's founding. The upper levels housed the records storage, while Okuni's personal chambers were located in the lower levels. There was an additional level that contained a large sitting room, where Okuni preferred to meet guests and conduct business. A large portion of the mansion was destroyed in a fire, ultimately resulting in the loss of the archives and the murder of Okuni.
