Seventeen-year-old Kazuki Shikimori is a student at Aoi Academy, a prestigious institution dedicated to training elite magicians. In this world, every sorcerer is born with a strict limit on the number of spells they can cast throughout their lifetime. Exceeding this threshold carries a fatal consequence: the caster’s body will disintegrate into dust. Unfortunately for Kazuki, his personal magic count falls drastically below the academy’s average, leaving him with an alarmingly small reserve of usable spells and a precarious existence. His already fragile situation takes a dramatic turn when three girls suddenly appear in his life. Rather than seeking his affection or companionship, their true objective is far more unusual—they are after his genetic material. Despite his low spell count, Kazuki possesses a highly coveted bloodline that makes him an invaluable target for these determined young women. As the girls relentlessly pursue him, Kazuki faces a terrifying realization. His remaining magic count is steadily decreasing with each passing day. Caught between their aggressive advances and his dwindling lifespan, he must navigate a dangerous predicament where the very attention threatening to complicate his life may ultimately seal his doom.
