Yuffie Kisaragi a video game character from Square Enix's Final Fantasy series. Designed by Tetsuya Nomura, she was first introduced in the 1997 role-playing video game Final Fantasy VII as a young female ninja princess and thief. She can become one of the game's player characters after finishing a special sidequest. Yuffie reappears in the Compilation of Final Fantasy VII series, expanding her background and showing her after the events of the original game. Yuffie has also been featured in other Square Enix games, most notably the Kingdom Hearts crossover series, voiced by Yumi Kakazu in the Japanese versions of the games. In the English versions, Christy Carlson Romano provides her voice for Kingdom Hearts and Final Fantasy VII: Advent Children, and Mae Whitman is Yuffie's voice for Kingdom Hearts II and Dirge of Cerberus: Final Fantasy VII. The character has achieved a high level of popularity in Japan, but the English-language media reception has been more mixed.
