Aisa

Aisa (アイサ) is a small brave Shandian girl.

Personality
Since she was born, she had the ability known as "mantra". Because of this, she hates it when people die and will try anything to stop it, even rushing into danger without any plans on what to do.

Aisa is good friends with Laki and tends to bring her gifts like bags of dirt, which are considered holy and are called Vearth in the sky. Aisa wants to be a strong fighter like everyone else but is afraid of Wiper, though she warms up to him eventually. Aisa is a bit of a tomboy as she reacted with disgust when Laki suggested she grow her hair longer because it would look cute on her.

Mantra
Aisa was born with the ability known as Mantra (later revealed to be a kind of Haki), which gave her a sixth sense of the world around her. She can sense when people die as well as the feelings of others.

Weapons
Aisa was often seen carrying a Burn Blade as protection for herself. Though she carries a Burn Blade and used it on several occasions to threaten others with it, she is never shown using it.

Skypiea Arc
She is the one who reveals the defeat of both Satori and Gan Fall to the rest of the tribe, and later tries to stop all of the killing by going to Upper Yard, where she meets the Straw Hat Pirates. Though she is initially afraid of them, she soon warms up to the pirates, especially Luffy and Nami. Aisa helps Luffy locate Enel and after the war ends, Aisa no longer has to be a warrior.

The last time she is seen she is taking a walk on the Vearth with Laki, Conis and Norla.
