Cecilia Lynn - Magical Angel Fairy Princess

Cecilian Lynn from Magical Angel Fairy Princess, a game by Umai Neko

The only protag from the Magical Angel series with a civilian name (afaik, her game is the only one with plot)

EDIT April 10th: - Remaking her in Illustrious was a priority since she was a popular model for a couple of months, before being dethroned by Aisha
