Raikou Episode 1

When the legendary gem Magatama is stolen by the barbaric Tsuchigumo clan, one noble warrior receives the order to bring the jewel back to the capital city of Heian: his name is Minamoto no Raiko. But Raiko's unexpected illness forces him to renounce the accomplishment of his perilious mission. And so Hikaru, the youngest daughter of the Minamoto family, disguises herself as a man, and assuming the identity of her elder brother Raiko, starts her journey in search of the Magatama. Together with Watanabe no Tsuna, an one-eyed retainer who made an oath of brotherhood with Raiko, Hikaru heads to Hitachi-no-Kuni, the land of the Tsuchigumo clan, but she is attacked by her enemies on the way. Her hands hesitate while she draws her bow, and for the first time in her life, Hikaru shoots an arrow at another human being.
