Kouun-chi 999 no Watashi, ga Zettai ni Seikou Suru node Sekai Saikyou desu: Maryoku-chi 1 de Tsuihou Saremashita ga, Kakuritsu Cheat de Moriagaru

Sachi was born into a prestigious family of magicians, in a world where magical power determines a person's worth and future. When her own magical capacity was measured, it registered at a mere 1. That devastating result filled her with despair, for it seemed to place her far below the standards of both her lineage and the society around her. By contrast, her luck stat was extraordinary: an astonishing 999. Yet the magicians of her world regarded such fortune as worthless. Luck could not perform magic or uphold a prestigious name, so Sachi's one remarkable attribute was dismissed as meaningless. Trapped between a crippling magical deficiency and a peerless but unappreciated luck stat, Sachi faces a painful dilemma. The very system that measures talent refuses to recognize the one area in which she excels. Her story centers on her struggle to define her own worth in a world that has already judged her by a single number.
