Maburaho

In Maburaho, magic is a universal birthright, but status hinges on a single number: how many times a person can cast spells in their lifetime. With talent fixed by heredity, lineages tied to renowned magicians carry enormous social value, and bloodlines are treated as commodities as much as gifts.

At Aoi Academy, Kazuki Shikimori has the lowest magic count in the school and earns little more than scorn for it—yet his ancestry is filled with celebrated mages, making him a coveted prospect for the future. His quiet life is upended by three girls with very different intentions: Yuna Miyama, a transfer student who immediately claims him as her husband; Rin Kamishiro, a proud swordswoman from a traditional family who insists she must kill him to pursue her own wishes; and Kuriko Kazetsubaki, an influential heiress who bluntly pursues him for his genes. Caught between their demands and the resentment of his classmates, Kazuki finds himself at the center of a chaotic, romantic scramble he never asked for.
