Sixteen-year-old Subaru Sumeragi, the main character, is a very powerful magician, the thirteenth head of the foremost family of onmyōji in Japan, which has served the Emperor for centuries. As such, he is called upon to solve various occult mysteries, or stumbles himself on people whom his kind nature compels him to help. These occurrences form the main plot of most chapters. He lives in Tokyo with his twin sister Hokuto, an exuberant girl whose chief occupations are to design eccentric clothing for herself and her brother, and to egg on their mutual friend Seishirō Sakurazuka, a kindly, 25-year-old veterinarian, when he declares his love for Subaru. Possible casual nudity. U.S. Manga. With commentary by Thomas Safer.
