Toriko Tsukigata is a beautiful girl who judges guys solely upon their appearance. One day her life changes: Someone tells her that she's the eighth reincarnation of Princess Kaguya, who is a playgirl. To pay for the sins Princess Kaguya commited in her past life, she has to find a guy whom she really loves. If she fails, Toriko will become a hundred-year-old grandma. (Source: MU)
