Ai

was a hanyō from Hōrai Island. She is the youngest of the children that are living there, and she appears only in the fourth InuYasha movie.

History
Ai was the only child on Hōrai Island that escaped being marked by the war gods. Because of this, she is the only one able to escape the island.

Although she does not want to leave her friends, they (Especially Asagi) order her to leave, wanting her to be safe. When she escapes the island, one of the Four War Gods tries to kill her, but Inuyasha and his friends come to save her. Kagome takes her, and when Ai sees Inuyasha she seems to recognize him. It is revealed that Inuyasha had been on Hōrai Island with Kikyō fifty years prior. Ai later returns to the island, wanting to see the others again.

At the end of the film, she sets out with the other remaining half-demon children to live in the outside world.

Personality
Ai is the youngest of the half-demon children, and she is also the most innocent and optimistic. She seems too young to comprehend the severity of some of the situations, and is always looking at the bright side of things. She looks up to Inuyasha and all the other children, although she is pretty strong-willed herself.

Physical description
Ai is a small, skinny, half-demon child. She has purple hair that is always in a messy bun at the back of her head, tied up with a band of pearls. She has blue eyes and her being half-demon is shown through her ears. Her ears are blue and fin-like, making it safe to assume she is part fish-demon. She has peachy skin.

Outfit
Ai wears a pink 'dress' and is barefoot. There is a small pink ribbon hanging off the very middle back of the dress.
