Safe Zones (Karma x Reader)

"Safe zones aren't made to keep other out, they were made to keep us in."

Y/n L/n was born as a test tub baby with 450 others in a underground lab. At age 14 she runs away to an abandoned building near a broken down school, leaving with the only 4 alive 'Ultimates' called Cyber, Rin, Haruhi, and Keizo and a young scientist named Kyo. When they find out that Karasuma is assigned to bring them back, they set out to find him only to be stopped by Koro-sensei. How will Class E react to The Ultimates? Why are the Ultimates made? Will they ever actually feel safe?
