The heroine grew up in an orphanage. Her parents died in a car accident. She has some emotional and cognitive impairment, but she trusts others easily. Once Gomu was accidentally involved in a mission, and was found to have magical powers, so he was abducted by Gojo Satoru and sent to a high school... Maybe some plot changes will be made, but it won't be too outrageous.
Purpose: Skynet is vast, omissions are not omitted, sweeping/blackout/eliminating/everyone is responsible for evildoers
