In an alternate reality where magic exists and an individual's status in society is measured by their magical abilities, inept Kazuki Shikimori just doesn't seem to fit in. Though he attends a prestigious school for the elite, his abilities are abysmal, and he's constantly teased by his classmates. Resigned to being on the bottom rung, Kazuki's luck takes a dramatic twist when three beautiful girls — sweet Yuna, sexy Kuriko, and surly Rin — come calling on him, with their own agendas. However, little does Kazuki know that lying dormant inside him are the genes that are capable of producing an offspring with legendary magical properties!
