One of these people remarked that a region resembled "heart rings" formed by mating dragonflies, giving rise to one name for that region. The first of these people was the grandson of the prince Hoori and a woman who returned his borrowed fish hook. One of these people battled "shrimp barbarians" during their travels East guided by a three-legged crow. (*) Suinin is the first of these people to have possibly existed, though Jimmu is the first recorded one. (10[2])In a ceremony, priests present these people with a mirror, jewel, and sword known as the Three Sacred Treasures. According to the Kojiki, these rulers descend from a goddess who caused darkness by hiding in a cave. For 10 points, name these rulers who are said to be descended from Amaterasu. ■END■
