Inuyasha the Movie: Fire on the Mystic Island: Ai

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.
