Minamoto no Hikaru is a young girl that has been secretly assigned by her father to pose as her brother, Minamoto no Raikou due to Raikou being severely sick. In her brother's stead, she is supposed to retrieve the Magatama of Fire, Water, Wind, and Earth through the orders of Seimei. She is at first attempting to retrieve the Magatama of Earth so as to heal her weakened near-to-death brother. Hikaru begins the story with her trusted retainer Watanabe no Tsuna in hopes of retrieving the Magatama. She later finds out that the Tsuchigumo clan is the holder of the Magatama.
