Kiwi & Mozu

Kiwi and Mozu are a pair of characters from One Piece, members of the Franky Family, known for their unique square-shaped hairstyles, earning them the nickname "Square Sisters." Though not twins, they are virtually identical in appearance, distinguished only by their hair: Kiwi has curly hair, while Mozu's is straight. They are fiercely loyal to Franky, often mimicking his actions and poses. During the Water 7 and Enies Lobby Arcs, they served as Franky's allies, briefly becoming adversaries of the Straw Hat Pirates. They currently co-manage Blueno's old bar in Water 7. In battle, they wield katanas with square-shaped handguards, displaying agility but not exceptional strength. Both are quite emotional, easily moved by sad stories, while simultaneously pretending to be unaffected. They demonstrated their loyalty and combat skills during the Water 7 Saga, and later became important allies of the Straw Hat Pirates.
