In my Phantom of the Opera AU story, Gem of the Sunset, Indigo Zap, like Erin, is a Topaz student. She is also a cast member of the “Phantom of the Opera” play. Like Sour Sweet, Indigo usually wears her summer uniform, which comes in two styles like Indigo’s. Description: She wears a white collared shirt with dark yellow bow tie and topaz brooch under a yellow top with a golden collar and buttons, golden skirt with yellow lines, black short socks, and brown shoes. She also has a yellow diamond ring, showing her diamond’s Yellow Diamond. Personality: The same as the original Indigo Zap.
