Aerith

Aerith is a character who lives in Traverse Town in Kingdom Hearts and Kingdom Hearts Chain of Memories, and in Hollow Bastion/Radiant Garden in Kingdom Hearts II. Like many of Sora's allies, she originates from Final Fantasy VII.

Aerith, as an ally of Leon and Yuffie, is one of the three core Final Fantasy characters of the series, and takes an active support role with them in the defense of Hollow Bastion in Kingdom Hearts II. She also plays a part in Cloud's story, though does not directly assist him as she does her other allies.
