Summary
Mozu and her twin sister Kiwi are affectionately known as the Square Sisters (スクエアシスターズ) because of their distinctive square-shaped hairstyles. They are fiercely loyal to Franky, following him wherever he goes and often mimicking his reactions. Mozu is distinguished by her yellow bikini top, yellow slacks, and straight-edged hair, whereas Kiwi wears a red top and red bikini bottom with curly-edged hair. Due to the aerodynamic properties of their unique hair, they have to walk sideways during high winds to avoid being blown backward. In combat, they wield samurai swords, though they lack significant strength, as evidenced by Franky and Kalifa easily subduing them. Additionally, both sisters have a lifelong habit of appending the word "Waina" to the end of every sentence they speak.
