Sara Shiranui

Sara Shiranui (サラ / 不知火 皐羅) is a prominent character in the Spirits' Difficult Life series.

Official Description
Sara is a flame spirit who came to the human world to pass the Trial of Maturity. She currently lives at Tomori's house rent-free.

Appearance
She has long red hair and blue eyes. She has two bands of white cloth wrapped in each side of her hair and a ribbon - the three serve as a seal to limit her true fire abilities.

Background
Like many spirits in the four elemental realms - earth, fire, wind, and water - Sara is to undertake the Trial of Maturity, a test where one must come to earth and steal the most precious item from the first human they meet. Prior to the test, Sara is instructed by her mother that she would be sent to Japan, and that she must wear a special cloth to dampen her flame abilities. Eventually, she lands in a tulip patch at a Japanese park, and is first seen by Tomori, whom would be Sara's target from then on.

While on Earth, Sara assumes a Japanese identity by keeping her first name, but rendering it with Japanese characters and adding Shiranui as her last name. With Tomori being the focus of her journey in the human realm, Sara manages to bond with her and eventually end up living in the same roof together, all the while attending the same middle school as classmates. She secretly attempts to find out Tomori's most valuable and precious item, but is so fascinated with the culture on earth that she sometimes forgets the real reason she is there.

Since Sara is unable to return to the spiritual realm while taking the trial of maturity, she is occasionally visited by a talking bird named Phoeni, who aids Sara through her mother's wishes.
