The Red Shadow: Government agent.

Amaia must understand the world around her without her mother's constant guidance. She takes refuge in the government and becomes the youngest agent.
She will reconnect with old acquaintances and her own inner monsters. Not only is she a 13-year-old girl searching for a path in her life, but she is also trying to escape the shadow of her mother and the nickname placed upon her by the people who created her. Although she may also find advantages in it, being a government agent doesn't always have to be a negative thing.
The events take place during the series "Falcon and the Winter Soldier" with slight changes. The relationship between Amaia and Bucky will simply be as friends.
(The characters belong to Marvel, those you don't recognize are my creation.)
