Description
Aisa is a young girl from the Shandia tribe, residing in the cloud island of Skypiea. She is a descendant of the legendary warrior Calgara, and her mother is named Isa. At the time of the Skypiea conflict, Aisa is nine years old and stands 140 centimeters tall. She has short, violet-brown hair, brown eyes, and the small feathered wings characteristic of her people. Her typical outfit includes a fur-trimmed dress and a matching cap. Aisa has a fondness for sweet cloud confections and often sneaks onto the sacred Upper Yard to collect Vearth, the ordinary soil that is considered a precious treasure in the sky.

Aisa possesses a powerful innate ability known as Mantra, which is a form of Observation Haki. She has had this ability since birth, granting her extrasensory perception to sense the presence, emotions, and life force of people across a vast area. Because she cannot control this power, she is constantly aware of pain and death, which causes her great distress and has made her hate war and violence. As a baby, she would cry whenever battles broke out among her people.

Despite her sensitivity, Aisa has a strong will and a deep sense of justice. She greatly admires the Shandia warriors, particularly their leader Wyper, and proudly calls herself a warrior. She is tomboyish, brave, and sometimes reckless, rushing into dangerous situations to try and stop people from getting hurt. During the conflict against the self-proclaimed god Enel, Aisa allies with the Straw Hat Pirates. After being rescued by Conis and her father Pagaya, she is brought to the Going Merry. She initially reacts with hostility toward the blue-sea dwellers but eventually bonds with them, especially Nami and Monkey D. Luffy. Her Mantra ability becomes vital for tracking Enel’s movements and locating captured crewmates. She accompanies Luffy through the final stages of the battle and tearfully asks if Skypiea will truly disappear.

After Enel is defeated by Luffy, Aisa is overjoyed to be reunited with her close friend Raki, who is a caring maternal figure to her. In a symbolic gesture of the peace that has come to Skypiea, Raki cuts Aisa’s short hair, suggesting she can now focus on being a normal girl. Aisa is the only one of the Shandia to personally say goodbye and thank Luffy before his crew departs. Two years later, she has grown taller, keeps her hair in two braids, and works as a cloud balloon salesgirl at an amusement park, living peacefully in the world Luffy and his friends helped save.
