When witches turn thirteen, they summon a guardian "cat" who stays with them and supports them their entire life. This is a story of witches and cats, a story of four friends at magic school -- Suzu, Kei, Mary, and Nina -- who all learn something about life as they turn thirteen and meet their cats.
