Belle

Belle is a character from Kingdom Hearts and Kingdom Hearts II. She is originally from the Disney animated film Beauty and the Beast.

Kingdom Hearts
Belle, as a Princess, was kidnapped by Maleficent as part of the plot to obtain Kingdom Hearts. But the Beast came to rescue her, and succeeded with the help of Sora. Afterwards, the two returned to Beast's Castle together.

Kingdom Hearts II
Belle had been living happily with the Beast until trouble arrived in the form of Organization XIII member Xaldin. Xaldin began filling the Beast's heart with rage, hoping to turn him into a Heartless to obtain his powerful Nobody. But Sora and the Beast's servants were able to calm him. As that happened, Belle gave chase to Xaldin, following him to the ballroom, where he unleashed the Shadow Stalker. Together, the Beast and Sora vanquished the massive Heartless and peace returned to the castle.

It was not to last, however. Xaldin returned to steal the Beast's precious rose, and later kidnapping Belle. But she managed to escape with the rose, and Xaldin was defeated. Afterwards, Belle and the Beast continued to live together.
