Mozu (モズ, Mozu) and Kiwi (キウィ, Kiwi), also known as the Square Sisters (スクエアシスターズ, Sukuea Shisutāzu) due to their square-like hairstyle, are very loyal to Franky, and go with him everywhere. They have a tendency to mimic his reactions. They often walk sideways in high winds due to the fact that they are blown back.

History

When CP9 invades their hideout, they are knocked down and out by Kalifa for not letting them in. Later when the Straw Hats chase after the sea train, Puffing Tom, with the Rocketman. Mozu and Kiwi along with the rest of the Franky family, accompany them to the government headquarters, Enies Lobby, as Franky was captured by CP9. Once there they help hold off the naval marines to allow the Straw Hats go on ahead and try to rescue Franky and Nico Robin. They were blown into the Enies Lobby waterfall by cannonfire, but are currently safe thanks to the giants and Paulie.
