In a near-future Kanazawa, a special district exists for the "alpha," a rare group of one-in-100,000 individuals who are intelligent, attractive, and exceptional. Kohaku Ieyasu, the top figure in this society, was set to marry an omega, but Saru, a regular beta, takes her sister's place. This leads to a lavish narrative blending the Omegaverse and marriage battle genres.
