Ten years ago, the Pure Maidens saved the world from Nega-Force. They then retired, married, and got on with their lives—until Nega-Force rebranded as Neo Nega-Force and came back. The former heroines are now older, more experienced, and arguably more powerful than they were the first time. Ryohei, a normal citizen, discovers that his neighbor Ayumi is Pure Sapphire when he witnesses her transform mid-fight—and uses it to blackmail her. A magical girl parody that keeps its tongue firmly in its cheek.
