Miyuki was born into the Murakami clan as the only daughter of Hanabi and Gofuku and was praised by all as the best of her generation; a genius above all others. Even by the standards of the Murakami clan, Miyuki's prowess far outshone their own. In her early years, Miyuki was the subject of great envy from her Academy classmates, who were jealous of her because of her great ninja skills and the fact that she was younger than all of them. Miyuki became a shy individual, and it only was years later that she made up with her classmates and became an outgoing person.
