Madeline

Madeline is one of the hostesses under the employ of Central City's Madame Christmas and, as such, moonlights as part of the aforementioned madame's covert information network.

In Chapter 69, she is seen passing information about the ongoings at Fort Briggs to Roy Mustang under cover of dating him. It appears that she is otherwise very social, as she opts to go shopping with friends after receiving payment from him for her trouble.

As the Promised Day approaches, it is revealed that Madeline and the other women from the hostess bar have all been smuggled to safety outside the country under Madame Christmas' orders.
