Maburaho is set in a world where every character has the ability to use magic, however everyone's magic is not equal. Each person in the story has a different degree of magic and a set number of times that they can use their magic. The average person is able to use magic less than a hundred times, however some people are able to use magic several thousand times. Because of this, a person's social standing is determined by the number of times that he or she can perform magic. If someone uses up all of their magic, his or her body turns to ash and is scattered into the winds. The series first introduces us to Kazuki Shikimori, a second year student from an elite magic school, Aoi Academy. However, unlike his classmates, Kazuki can only use his magic eight times before he turns to dust. As a result, he is at the bottom of the school's social pecking order. However things change one day when Yuna Miyama shows up in his dorm room and declares that she is his wife. Moments later, Kuriko Kazetsubaki and Rin Kamishiro appear at Kazuki's dorm, the former in order to obtain his genes and the latter to kill him to escape her obligation to marry him. Kazuki learns that he is a descendant of most of the world's greatest magicians from both the eastern and western worlds. Even though he has a feeble spell count, his offspring has the potential of becoming a powerful magician.
