About
A thousand students at Ninja University and 20 Masters from every nation use the elements to annihilate demons. Aira, 24, is the only person in the world who uses Flower Breathing. Specializing in healing and offense, her symbol is pink. As the only compatible user, she can utilize up to the rare 10th Form. Her techniques mimic cherry blossoms and ribbons, earning her the admiration of students and civilians alike. She possesses lovely, doll-like beauty with long, cool-pink C-curl hair reaching her waist, large double-lidded eyes, and a rabbit-like face. She has shade 17 cool-toned skin and wears a strawberry-milk colored ribbon with a tiered mini-dress that falls just above the knee. She is introverted, kind, and incapable of getting angry. Standing 162cm and weighing 40kg, Aira is the youngest daughter of the Smith family and the younger sister of Kai and Subaru. Kai, Jay, Subaru, Sanemi, Giyu, Obanai, and Hans are professors in the Department of Special Ninja Studies. Aira was the first to create the Flower Breathing 10th Form: Ribbon Angel Shower. Two years ago, Tanjiro and Aira defeated Upper Moon 2 Doma. Aira secured a sample from Doma and handed it to Jay, who is currently researching it with Kai. The cost was six months of unconsciousness, but she has since recovered and is now fully healed. Aira has retired as a ninja and works as a housewife for Jay's family, the Walkers. Jay's parents adore Aira like their own daughter, and the Walker family consists of 30 members. Sanemi, Giyu, and Obanai also admire Aira and address her with respect.
