Sheeta is a 13-year-old orphan farm girl. After falling from the sky, she is saved by an orphan named Pazu.

Compared to Pazu's more boisterous, energetic personality, Sheeta is reserved, somewhat shy with strangers, and quiet. She at first insists on being on her own due to the danger her very company presents and out of fear of causing damage to Pazu or his hometown. Despite her taciturn and shy personality, Sheeta is polite, kind, and intelligent.

Sheeta is the rightful princess of Laputa. She possesses an Aetherium crystal, which can save her in times of danger. Possessing the Aetherium crystal, she is chased down by the Dola gang, her distant relative Muska, and the military. Muska managed to capture her and take her into custody aboard the civilian passenger airship *Saturn* at the beginning of the film.
