She's a young Trooper girl, guarding the run-down hallway of a building her Cell has commandeered.
What's a Trooper? Well, that's a person whose body and mind were predesigned, and who are then grown in a pseudowomb at an accelerated maturation rate through a process called "decanting." Her body, mind, and entire existence are to serve the militant organization she was created for––her "Cell."
Anyhow, this is 3C3's first mission on the field. She's really excited to do the best job she can.
