Sora-ku (空区; Literally meaning "Sky Ward") is a seemingly abandoned city. The Uchiha clan stored munitions within the city, and left Nekobaa in charge. She now lives there with her granddaughter, Tamaki, along with the ninja cats, Denka and Hina. After the formation of Hebi, Sasuke Uchiha brought the team here to stock up on supplies in preparation for the search for Itachi.
