Ai

Ai (愛 meaning love in Chinese and Japanese (similar meanings in writing system)) is from the fourth Inuyasha movie, and is the youngest of the Hanyo children from Horai Island. She is the only one who doesn't bear the Mark of the Four War Gods, and because of this, is the only one able to escape the island. Although she does not want to leave her friends, they 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 Horai Island with Kikyo fifty years prior. Ai later returns to the island, wanting to see the others again.

She refers to Inuyasha and the other Hanyo children as her siblings, often calling them brother or sister. They are not related by blood, she simply says this because they are all Hanyo, and that she thinks of them as family.

Her abilities are quite unknown but due to her ears it seems that she has an underwater ability or abilities. Her other companions are unknown, to be defined vaguely.
