Becky Blackbell is the daughter of the CEO of Blackbell Heavy Industries, a major military manufacturer. She attends Eden Academy as part of Cecile House, Group 3, and is Anya Forger's best friend.

Becky is a very kind child, but with her being the daughter of a major military manufacturer, she is shown to be somewhat prideful and tries to be mature, attempting to take Anya under her wing as an act of benevolence when she views Anya as a brat. She does not attempt to get close to Damian Desmond despite his social position, even looking down on their classmates who try to befriend Damian and Anya who is initially bullied by Damian's group.
