Kairi

Kairi is a young girl who lived in Innenjima prior to the town's destruction by a massive Fangirl swarm in 2005.  She appears in Roxas' occasional flashbacks to his life before the Organization, though due to his memory loss he can't remember who she is.  She was also friends with Riku Hashimoto of the Keybearers, who has likely been searching for her over the year that has passed since he joined that group.

Her current whereabouts and status are unknown.
