Raimei Shimizu is a 14-year-old guardian of the world of Nabari and head of Fuuma Village's Shimizu clan. She prefers to fight with a sword named Kurogamon over using ninjutsu to the point of claiming to be a samurai. Five years ago, her older brother Raikō annihilated their clan. She has sworn to kill him in revenge. The two reconcile and stay on friendly terms after Raimei learns that the massacre was Raikō's vengeance against their uncle and his gang, who killed Raikō and Raimei's parents. She has a tendency to mistake one person for another or reveal information she intended to keep to herself when excited. She is voiced by Ayumi Fujimura in Japanese and Kate Oxley in English.
